AcceptVpcPeeringConnection([DryRun => Bool, VpcPeeringConnectionId => Str])

Returns: a Paws::EC2::AcceptVpcPeeringConnectionResult instance

Accept a VPC peering connection request. To accept a request, the VPC peering connection must be in the "pending-acceptance" state, and you must be the owner of the peer VPC. Use the "DescribeVpcPeeringConnections" request to view your outstanding VPC peering connection requests.

AllocateAddress([Domain => Str, DryRun => Bool])

Returns: a Paws::EC2::AllocateAddressResult instance

Acquires an Elastic IP address.

An Elastic IP address is for use either in the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

AssignPrivateIpAddresses(NetworkInterfaceId => Str, [AllowReassignment => Bool, PrivateIpAddresses => ArrayRef[Str], SecondaryPrivateIpAddressCount => Int])

Returns: nothing

Assigns one or more secondary private IP addresses to the specified network interface. You can specify one or more specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned within the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For information about instance types, see Instance Types in the Amazon Elastic Compute Cloud User Guide. For more information about Elastic IP addresses, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

AssignPrivateIpAddresses is available only in EC2-VPC.

AssociateAddress([AllocationId => Str, AllowReassociation => Bool, DryRun => Bool, InstanceId => Str, NetworkInterfaceId => Str, PrivateIpAddress => Str, PublicIp => Str])

Returns: a Paws::EC2::AssociateAddressResult instance

Associates an Elastic IP address with an instance or a network interface.

An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

[EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.

[VPC in an EC2-Classic account] If you don't specify a private IP address, the Elastic IP address is associated with the primary IP address. If the Elastic IP address is already associated with a different instance or a network interface, you get an error unless you allow reassociation.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

AssociateDhcpOptions(DhcpOptionsId => Str, VpcId => Str, [DryRun => Bool])

Returns: nothing

Associates a set of DHCP options (that you've previously created) with the specified VPC, or associates no DHCP options with the VPC.

After you associate the options with the VPC, any existing instances and all new instances that you launch in that VPC use the options. You don't need to restart or relaunch the instances. They automatically pick up the changes within a few hours, depending on how frequently the instance renews its DHCP lease. You can explicitly renew the lease using the operating system on the instance.

For more information, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

AssociateRouteTable(RouteTableId => Str, SubnetId => Str, [DryRun => Bool])

Returns: a Paws::EC2::AssociateRouteTableResult instance

Associates a subnet with a route table. The subnet and route table must be in the same VPC. This association causes traffic originating from the subnet to be routed according to the routes in the route table. The action returns an association ID, which you need in order to disassociate the route table from the subnet later. A route table can be associated with multiple subnets.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

AttachClassicLinkVpc(Groups => ArrayRef[Str], InstanceId => Str, VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::AttachClassicLinkVpcResult instance

Links an EC2-Classic instance to a ClassicLink-enabled VPC through one or more of the VPC's security groups. You cannot link an EC2-Classic instance to more than one VPC at a time. You can only link an instance that's in the "running" state. An instance is automatically unlinked from a VPC when it's stopped - you can link it to the VPC again when you restart it.

After you've linked an instance, you cannot change the VPC security groups that are associated with it. To change the security groups, you must first unlink the instance, and then link it again.

Linking your instance to a VPC is sometimes referred to as attaching your instance.

AttachInternetGateway(InternetGatewayId => Str, VpcId => Str, [DryRun => Bool])

Returns: nothing

Attaches an Internet gateway to a VPC, enabling connectivity between the Internet and the VPC. For more information about your VPC and Internet gateway, see the Amazon Virtual Private Cloud User Guide.

AttachNetworkInterface(DeviceIndex => Int, InstanceId => Str, NetworkInterfaceId => Str, [DryRun => Bool])

Returns: a Paws::EC2::AttachNetworkInterfaceResult instance

Attaches a network interface to an instance.

AttachVolume(Device => Str, InstanceId => Str, VolumeId => Str, [DryRun => Bool])

Returns: a Paws::EC2::VolumeAttachment instance

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

Encrypted EBS volumes may only be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

For a list of supported device names, see Attaching an EBS Volume to an Instance. Any device names that aren't reserved for instance store volumes can be used for EBS volumes. For more information, see Amazon EC2 Instance Store in the Amazon Elastic Compute Cloud User Guide.

If a volume has an AWS Marketplace product code:

• The volume can be attached only to a stopped instance.
• AWS Marketplace product codes are copied from the volume to the instance.
• You must be subscribed to the product.
• The instance type and operating system of the instance must support the product. For example, you can't detach a volume from a Windows instance and attach it to a Linux instance.

For an overview of the AWS Marketplace, see Introducing AWS Marketplace.

For more information about EBS volumes, see Attaching Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

AttachVpnGateway(VpcId => Str, VpnGatewayId => Str, [DryRun => Bool])

Returns: a Paws::EC2::AttachVpnGatewayResult instance

Attaches a virtual private gateway to a VPC. For more information, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

AuthorizeSecurityGroupEgress(GroupId => Str, [CidrIp => Str, DryRun => Bool, FromPort => Int, IpPermissions => ArrayRef[Paws::EC2::IpPermission], IpProtocol => Str, SourceSecurityGroupName => Str, SourceSecurityGroupOwnerId => Str, ToPort => Int])

Returns: nothing

Adds one or more egress rules to a security group for use with a VPC. Specifically, this action permits instances to send traffic to one or more destination CIDR IP address ranges, or to one or more destination security groups for the same VPC.

You can have up to 50 rules per security group (covering both ingress and egress rules).

A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. This action doesn't apply to security groups for use in EC2-Classic. For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

Each rule consists of the protocol (for example, TCP), plus either a CIDR range or a source group. For the TCP and UDP protocols, you must also specify the destination port or port range. For the ICMP protocol, you must also specify the ICMP type and code. You can use -1 for the type or code to mean all types or all codes.

Rule changes are propagated to affected instances as quickly as possible. However, a small delay might occur.

AuthorizeSecurityGroupIngress([CidrIp => Str, DryRun => Bool, FromPort => Int, GroupId => Str, GroupName => Str, IpPermissions => ArrayRef[Paws::EC2::IpPermission], IpProtocol => Str, SourceSecurityGroupName => Str, SourceSecurityGroupOwnerId => Str, ToPort => Int])

Returns: nothing

Adds one or more ingress rules to a security group.

EC2-Classic: You can have up to 100 rules per group.

EC2-VPC: You can have up to 50 rules per group (covering both ingress and egress rules).

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

[EC2-Classic] This action gives one or more CIDR IP address ranges permission to access a security group in your account, or gives one or more security groups (called the source groups) permission to access a security group for your account. A source group can be for your own AWS account, or another.

[EC2-VPC] This action gives one or more CIDR IP address ranges permission to access a security group in your VPC, or gives one or more other security groups (called the source groups) permission to access a security group for your VPC. The security groups must all be for the same VPC.

BundleInstance(InstanceId => Str, Storage => Paws::EC2::Storage, [DryRun => Bool])

Returns: a Paws::EC2::BundleInstanceResult instance

Bundles an Amazon instance store-backed Windows instance.

During bundling, only the root device volume (C:\) is bundled. Data on other instance store volumes is not preserved.

This action is not applicable for Linux/Unix instances or Windows instances that are backed by Amazon EBS.

For more information, see Creating an Instance Store-Backed Windows AMI.

CancelBundleTask(BundleId => Str, [DryRun => Bool])

Returns: a Paws::EC2::CancelBundleTaskResult instance

Cancels a bundling operation for an instance store-backed Windows instance.

CancelConversionTask(ConversionTaskId => Str, [DryRun => Bool, ReasonMessage => Str])

Returns: nothing

Cancels an active conversion task. The task can be the import of an instance or volume. The action removes all artifacts of the conversion, including a partially uploaded volume or instance. If the conversion is complete or is in the process of transferring the final disk image, the command fails and returns an exception.

For more information, see Using the Command Line Tools to Import Your Virtual Machine to Amazon EC2 in the Amazon Elastic Compute Cloud User Guide.

CancelExportTask(ExportTaskId => Str)

Returns: nothing

Cancels an active export task. The request removes all artifacts of the export, including any partially-created Amazon S3 objects. If the export task is complete or is in the process of transferring the final disk image, the command fails and returns an error.

CancelImportTask([CancelReason => Str, DryRun => Bool, ImportTaskId => Str])

Returns: a Paws::EC2::CancelImportTaskResult instance

Cancels an in-process import virtual machine or import snapshot task.

CancelReservedInstancesListing(ReservedInstancesListingId => Str)

Returns: a Paws::EC2::CancelReservedInstancesListingResult instance

Cancels the specified Reserved Instance listing in the Reserved Instance Marketplace.

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

CancelSpotFleetRequests(SpotFleetRequestIds => ArrayRef[Str], TerminateInstances => Bool, [DryRun => Bool])

Returns: a Paws::EC2::CancelSpotFleetRequestsResponse instance

Cancels the specified Spot fleet requests.

CancelSpotInstanceRequests(SpotInstanceRequestIds => ArrayRef[Str], [DryRun => Bool])

Returns: a Paws::EC2::CancelSpotInstanceRequestsResult instance

Cancels one or more Spot Instance requests. Spot Instances are instances that Amazon EC2 starts on your behalf when the bid price that you specify exceeds the current Spot Price. Amazon EC2 periodically sets the Spot Price based on available Spot Instance capacity and current Spot Instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

Canceling a Spot Instance request does not terminate running Spot Instances associated with the request.

ConfirmProductInstance(InstanceId => Str, ProductCode => Str, [DryRun => Bool])

Returns: a Paws::EC2::ConfirmProductInstanceResult instance

Determines whether a product code is associated with an instance. This action can only be used by the owner of the product code. It is useful when a product code owner needs to verify whether another user's instance is eligible for support.

CopyImage(Name => Str, SourceImageId => Str, SourceRegion => Str, [ClientToken => Str, Description => Str, DryRun => Bool])

Returns: a Paws::EC2::CopyImageResult instance

Initiates the copy of an AMI from the specified source region to the current region. You specify the destination region by using its endpoint when making the request. AMIs that use encrypted EBS snapshots cannot be copied with this method.

For more information, see Copying AMIs in the Amazon Elastic Compute Cloud User Guide.

CopySnapshot(SourceRegion => Str, SourceSnapshotId => Str, [Description => Str, DestinationRegion => Str, DryRun => Bool, Encrypted => Bool, KmsKeyId => Str, PresignedUrl => Str])

Returns: a Paws::EC2::CopySnapshotResult instance

Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy the snapshot within the same region or from one region to another. You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs). The snapshot is copied to the regional endpoint that you send the HTTP request to.

Copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless the "Encrypted" flag is specified during the snapshot copy operation. By default, encrypted snapshot copies use the default AWS Key Management Service (AWS KMS) customer master key (CMK); however, you can specify a non-default CMK with the "KmsKeyId" parameter.

For more information, see Copying an Amazon EBS Snapshot in the Amazon Elastic Compute Cloud User Guide.

CreateCustomerGateway(BgpAsn => Int, PublicIp => Str, Type => Str, [DryRun => Bool])

Returns: a Paws::EC2::CreateCustomerGatewayResult instance

Provides information to AWS about your VPN customer gateway device. The customer gateway is the appliance at your end of the VPN connection. (The device on the AWS side of the VPN connection is the virtual private gateway.) You must provide the Internet-routable IP address of the customer gateway's external interface. The IP address must be static and can't be behind a device performing network address translation (NAT).

For devices that use Border Gateway Protocol (BGP), you can also provide the device's BGP Autonomous System Number (ASN). You can use an existing ASN assigned to your network. If you don't have an ASN already, you can use a private ASN (in the 64512 - 65534 range).

Amazon EC2 supports all 2-byte ASN numbers in the range of 1 - 65534, with the exception of 7224, which is reserved in the "us-east-1" region, and 9059, which is reserved in the "eu-west-1" region.

For more information about VPN customer gateways, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

You cannot create more than one customer gateway with the same VPN type, IP address, and BGP ASN parameter values. If you run an identical request more than one time, the first request creates the customer gateway, and subsequent requests return information about the existing customer gateway. The subsequent requests do not create new customer gateway resources.

CreateDhcpOptions(DhcpConfigurations => ArrayRef[Paws::EC2::NewDhcpConfiguration], [DryRun => Bool])

Returns: a Paws::EC2::CreateDhcpOptionsResult instance

Creates a set of DHCP options for your VPC. After creating the set, you must associate it with the VPC, causing all existing and new instances that you launch in the VPC to use this set of DHCP options. The following are the individual DHCP options you can specify. For more information about the options, see RFC 2132.

• "domain-name-servers" - The IP addresses of up to four domain name servers, or "AmazonProvidedDNS". The default DHCP option set specifies "AmazonProvidedDNS". If specifying more than one domain name server, specify the IP addresses in a single parameter, separated by commas.
• "domain-name" - If you're using AmazonProvidedDNS in "us-east-1", specify "ec2.internal". If you're using AmazonProvidedDNS in another region, specify "region.compute.internal" (for example, "ap-northeast-1.compute.internal"). Otherwise, specify a domain name (for example, "MyCompany.com"). Important: Some Linux operating systems accept multiple domain names separated by spaces. However, Windows and other Linux operating systems treat the value as a single domain, which results in unexpected behavior. If your DHCP options set is associated with a VPC that has instances with multiple operating systems, specify only one domain name.
• "ntp-servers" - The IP addresses of up to four Network Time Protocol (NTP) servers.
• "netbios-name-servers" - The IP addresses of up to four NetBIOS name servers.
• "netbios-node-type" - The NetBIOS node type (1, 2, 4, or 8). We recommend that you specify 2 (broadcast and multicast are not currently supported). For more information about these node types, see RFC 2132.

Your VPC automatically starts out with a set of DHCP options that includes only a DNS server that we provide (AmazonProvidedDNS). If you create a set of options, and if your VPC has an Internet gateway, make sure to set the "domain-name-servers" option either to "AmazonProvidedDNS" or to a domain name server of your choice. For more information about DHCP options, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

CreateFlowLogs(DeliverLogsPermissionArn => Str, LogGroupName => Str, ResourceIds => ArrayRef[Str], ResourceType => Str, TrafficType => Str, [ClientToken => Str])

Returns: a Paws::EC2::CreateFlowLogsResult instance

Creates one or more flow logs to capture IP traffic for a specific network interface, subnet, or VPC. Flow logs are delivered to a specified log group in Amazon CloudWatch Logs. If you specify a VPC or subnet in the request, a log stream is created in CloudWatch Logs for each network interface in the subnet or VPC. Log streams can include information about accepted and rejected traffic to a network interface. You can view the data in your log streams using Amazon CloudWatch Logs.

In your request, you must also specify an IAM role that has permission to publish logs to CloudWatch Logs.

CreateImage(InstanceId => Str, Name => Str, [BlockDeviceMappings => ArrayRef[Paws::EC2::BlockDeviceMapping], Description => Str, DryRun => Bool, NoReboot => Bool])

Returns: a Paws::EC2::CreateImageResult instance

Creates an Amazon EBS-backed AMI from an Amazon EBS-backed instance that is either running or stopped.

If you customized your instance with instance store volumes or EBS volumes in addition to the root device volume, the new AMI contains block device mapping information for those volumes. When you launch an instance from this new AMI, the instance automatically launches with those additional volumes.

For more information, see Creating Amazon EBS-Backed Linux AMIs in the Amazon Elastic Compute Cloud User Guide.

CreateInstanceExportTask(InstanceId => Str, [Description => Str, ExportToS3Task => Paws::EC2::ExportToS3TaskSpecification, TargetEnvironment => Str])

Returns: a Paws::EC2::CreateInstanceExportTaskResult instance

Exports a running or stopped instance to an S3 bucket.

For information about the supported operating systems, image formats, and known limitations for the types of instances you can export, see Exporting EC2 Instances in the Amazon Elastic Compute Cloud User Guide.

CreateInternetGateway([DryRun => Bool])

Returns: a Paws::EC2::CreateInternetGatewayResult instance

Creates an Internet gateway for use with a VPC. After creating the Internet gateway, you attach it to a VPC using AttachInternetGateway.

For more information about your VPC and Internet gateway, see the Amazon Virtual Private Cloud User Guide.

CreateKeyPair(KeyName => Str, [DryRun => Bool])

Returns: a Paws::EC2::KeyPair instance

Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS private key. If a key with the specified name already exists, Amazon EC2 returns an error.

You can have up to five thousand key pairs per region.

The key pair returned to you is available only in the region in which you create it. To create a key pair that is available in all regions, use ImportKeyPair.

For more information about key pairs, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

CreateNetworkAcl(VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::CreateNetworkAclResult instance

Creates a network ACL in a VPC. Network ACLs provide an optional layer of security (in addition to security groups) for the instances in your VPC.

For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

CreateNetworkAclEntry(CidrBlock => Str, Egress => Bool, NetworkAclId => Str, Protocol => Str, RuleAction => Str, RuleNumber => Int, [DryRun => Bool, IcmpTypeCode => Paws::EC2::IcmpTypeCode, PortRange => Paws::EC2::PortRange])

Returns: nothing

Creates an entry (a rule) in a network ACL with the specified rule number. Each network ACL has a set of numbered ingress rules and a separate set of numbered egress rules. When determining whether a packet should be allowed in or out of a subnet associated with the ACL, we process the entries in the ACL according to the rule numbers, in ascending order. Each network ACL has a set of ingress rules and a separate set of egress rules.

We recommend that you leave room between the rule numbers (for example, 100, 110, 120, ...), and not number them one right after the other (for example, 101, 102, 103, ...). This makes it easier to add a rule between existing ones without having to renumber the rules.

After you add an entry, you can't modify it; you must either replace it, or create an entry and delete the old one.

For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

CreateNetworkInterface(SubnetId => Str, [Description => Str, DryRun => Bool, Groups => ArrayRef[Str], PrivateIpAddress => Str, PrivateIpAddresses => ArrayRef[Paws::EC2::PrivateIpAddressSpecification], SecondaryPrivateIpAddressCount => Int])

Returns: a Paws::EC2::CreateNetworkInterfaceResult instance

Creates a network interface in the specified subnet.

For more information about network interfaces, see Elastic Network Interfaces in the Amazon Elastic Compute Cloud User Guide.

CreatePlacementGroup(GroupName => Str, Strategy => Str, [DryRun => Bool])

Returns: nothing

Creates a placement group that you launch cluster instances into. You must give the group a name that's unique within the scope of your account.

For more information about placement groups and cluster instances, see Cluster Instances in the Amazon Elastic Compute Cloud User Guide.

CreateReservedInstancesListing(ClientToken => Str, InstanceCount => Int, PriceSchedules => ArrayRef[Paws::EC2::PriceScheduleSpecification], ReservedInstancesId => Str)

Returns: a Paws::EC2::CreateReservedInstancesListingResult instance

Creates a listing for Amazon EC2 Reserved Instances to be sold in the Reserved Instance Marketplace. You can submit one Reserved Instance listing at a time. To get a list of your Reserved Instances, you can use the DescribeReservedInstances operation.

The Reserved Instance Marketplace matches sellers who want to resell Reserved Instance capacity that they no longer need with buyers who want to purchase additional capacity. Reserved Instances bought and sold through the Reserved Instance Marketplace work like any other Reserved Instances.

To sell your Reserved Instances, you must first register as a seller in the Reserved Instance Marketplace. After completing the registration process, you can create a Reserved Instance Marketplace listing of some or all of your Reserved Instances, and specify the upfront price to receive for them. Your Reserved Instance listings then become available for purchase. To view the details of your Reserved Instance listing, you can use the DescribeReservedInstancesListings operation.

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

CreateRoute(DestinationCidrBlock => Str, RouteTableId => Str, [DryRun => Bool, GatewayId => Str, InstanceId => Str, NetworkInterfaceId => Str, VpcPeeringConnectionId => Str])

Returns: a Paws::EC2::CreateRouteResult instance

Creates a route in a route table within a VPC.

You must specify one of the following targets: Internet gateway or virtual private gateway, NAT instance, VPC peering connection, or network interface.

When determining how to route traffic, we use the route with the most specific match. For example, let's say the traffic is destined for 192.0.2.3, and the route table includes the following two routes:

• "192.0.2.0/24" (goes to some target A)
• "192.0.2.0/28" (goes to some target B)

Both routes apply to the traffic destined for 192.0.2.3. However, the second route in the list covers a smaller number of IP addresses and is therefore more specific, so we use that route to determine where to target the traffic.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

CreateRouteTable(VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::CreateRouteTableResult instance

Creates a route table for the specified VPC. After you create a route table, you can add routes and associate the table with a subnet.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

CreateSecurityGroup(Description => Str, GroupName => Str, [DryRun => Bool, VpcId => Str])

Returns: a Paws::EC2::CreateSecurityGroupResult instance

Creates a security group.

A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. For more information, see Amazon EC2 Security Groups in the Amazon Elastic Compute Cloud User Guide and Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

EC2-Classic: You can have up to 500 security groups.

EC2-VPC: You can create up to 100 security groups per VPC.

When you create a security group, you specify a friendly name of your choice. You can have a security group for use in EC2-Classic with the same name as a security group for use in a VPC. However, you can't have two security groups for use in EC2-Classic with the same name or two security groups for use in a VPC with the same name.

You have a default security group for use in EC2-Classic and a default security group for use in your VPC. If you don't specify a security group when you launch an instance, the instance is launched into the appropriate default security group. A default security group includes a default rule that grants instances unrestricted network access to each other.

You can add or remove rules from your security groups using AuthorizeSecurityGroupIngress, AuthorizeSecurityGroupEgress, RevokeSecurityGroupIngress, and RevokeSecurityGroupEgress.

CreateSnapshot(VolumeId => Str, [Description => Str, DryRun => Bool])

Returns: a Paws::EC2::Snapshot instance

Creates a snapshot of an EBS volume and stores it in Amazon S3. You can use snapshots for backups, to make copies of EBS volumes, and to save data before shutting down an instance.

When a snapshot is created, any AWS Marketplace product codes that are associated with the source volume are propagated to the snapshot.

You can take a snapshot of an attached volume that is in use. However, snapshots only capture data that has been written to your EBS volume at the time the snapshot command is issued; this may exclude any data that has been cached by any applications or the operating system. If you can pause any file systems on the volume long enough to take a snapshot, your snapshot should be complete. However, if you cannot pause all file writes to the volume, you should unmount the volume from within the instance, issue the snapshot command, and then remount the volume to ensure a consistent and complete snapshot. You may remount and use your volume while the snapshot status is "pending".

To create a snapshot for EBS volumes that serve as root devices, you should stop the instance before taking the snapshot.

Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected.

For more information, see Amazon Elastic Block Store and Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

CreateSpotDatafeedSubscription(Bucket => Str, [DryRun => Bool, Prefix => Str])

Returns: a Paws::EC2::CreateSpotDatafeedSubscriptionResult instance

Creates a data feed for Spot Instances, enabling you to view Spot Instance usage logs. You can create one data feed per AWS account. For more information, see Spot Instance Data Feed in the Amazon Elastic Compute Cloud User Guide.

CreateSubnet(CidrBlock => Str, VpcId => Str, [AvailabilityZone => Str, DryRun => Bool])

Returns: a Paws::EC2::CreateSubnetResult instance

Creates a subnet in an existing VPC.

When you create each subnet, you provide the VPC ID and the CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you want only a single subnet in the VPC), or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).

AWS reserves both the first four and the last IP address in each subnet's CIDR block. They're not available for use.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

If you launch an instance in a VPC using an Amazon EBS-backed AMI, the IP address doesn't change if you stop and restart the instance (unlike a similar instance launched outside a VPC, which gets a new IP address when restarted). It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.

For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

CreateTags(Resources => ArrayRef[Str], Tags => ArrayRef[Paws::EC2::Tag], [DryRun => Bool])

Returns: nothing

Adds or overwrites one or more tags for the specified Amazon EC2 resource or resources. Each resource can have a maximum of 10 tags. Each tag consists of a key and optional value. Tag keys must be unique per resource.

For more information about tags, see Tagging Your Resources in the Amazon Elastic Compute Cloud User Guide.

CreateVolume(AvailabilityZone => Str, [DryRun => Bool, Encrypted => Bool, Iops => Int, KmsKeyId => Str, Size => Int, SnapshotId => Str, VolumeType => Str])

Returns: a Paws::EC2::Volume instance

Creates an EBS volume that can be attached to an instance in the same Availability Zone. The volume is created in the regional endpoint that you send the HTTP request to. For more information see Regions and Endpoints.

You can create a new empty volume or restore a volume from an EBS snapshot. Any AWS Marketplace product codes from the snapshot are propagated to the volume.

You can create encrypted volumes with the "Encrypted" parameter. Encrypted volumes may only be attached to instances that support Amazon EBS encryption. Volumes that are created from encrypted snapshots are also automatically encrypted. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

For more information, see Creating or Restoring an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

CreateVpc(CidrBlock => Str, [DryRun => Bool, InstanceTenancy => Str])

Returns: a Paws::EC2::CreateVpcResult instance

Creates a VPC with the specified CIDR block.

The smallest VPC you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses). To help you decide how big to make your VPC, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

By default, each instance you launch in the VPC has the default DHCP options, which includes only a default DNS server that we provide (AmazonProvidedDNS). For more information about DHCP options, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

CreateVpcEndpoint(ServiceName => Str, VpcId => Str, [ClientToken => Str, DryRun => Bool, PolicyDocument => Str, RouteTableIds => ArrayRef[Str]])

Returns: a Paws::EC2::CreateVpcEndpointResult instance

Creates a VPC endpoint for a specified AWS service. An endpoint enables you to create a private connection between your VPC and another AWS service in your account. You can specify an endpoint policy to attach to the endpoint that will control access to the service from your VPC. You can also specify the VPC route tables that use the endpoint.

Currently, only endpoints to Amazon S3 are supported.

CreateVpcPeeringConnection([DryRun => Bool, PeerOwnerId => Str, PeerVpcId => Str, VpcId => Str])

Returns: a Paws::EC2::CreateVpcPeeringConnectionResult instance

Requests a VPC peering connection between two VPCs: a requester VPC that you own and a peer VPC with which to create the connection. The peer VPC can belong to another AWS account. The requester VPC and peer VPC cannot have overlapping CIDR blocks.

The owner of the peer VPC must accept the peering request to activate the peering connection. The VPC peering connection request expires after 7 days, after which it cannot be accepted or rejected.

A "CreateVpcPeeringConnection" request between VPCs with overlapping CIDR blocks results in the VPC peering connection having a status of "failed".

CreateVpnConnection(CustomerGatewayId => Str, Type => Str, VpnGatewayId => Str, [DryRun => Bool, Options => Paws::EC2::VpnConnectionOptionsSpecification])

Returns: a Paws::EC2::CreateVpnConnectionResult instance

Creates a VPN connection between an existing virtual private gateway and a VPN customer gateway. The only supported connection type is "ipsec.1".

The response includes information that you need to give to your network administrator to configure your customer gateway.

We strongly recommend that you use HTTPS when calling this operation because the response contains sensitive cryptographic information for configuring your customer gateway.

If you decide to shut down your VPN connection for any reason and later create a new VPN connection, you must reconfigure your customer gateway with the new information returned from this call.

For more information about VPN connections, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

CreateVpnConnectionRoute(DestinationCidrBlock => Str, VpnConnectionId => Str)

Returns: nothing

Creates a static route associated with a VPN connection between an existing virtual private gateway and a VPN customer gateway. The static route allows traffic to be routed from the virtual private gateway to the VPN customer gateway.

For more information about VPN connections, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

CreateVpnGateway(Type => Str, [AvailabilityZone => Str, DryRun => Bool])

Returns: a Paws::EC2::CreateVpnGatewayResult instance

Creates a virtual private gateway. A virtual private gateway is the endpoint on the VPC side of your VPN connection. You can create a virtual private gateway before creating the VPC itself.

For more information about virtual private gateways, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

DeleteCustomerGateway(CustomerGatewayId => Str, [DryRun => Bool])

Returns: nothing

Deletes the specified customer gateway. You must delete the VPN connection before you can delete the customer gateway.

DeleteDhcpOptions(DhcpOptionsId => Str, [DryRun => Bool])

Returns: nothing

DeleteSecurityGroup([DryRun => Bool, GroupId => Str, GroupName => Str])

Returns: nothing

Deletes a security group.

If you attempt to delete a security group that is associated with an instance, or is referenced by another security group, the operation fails with "InvalidGroup.InUse" in EC2-Classic or "DependencyViolation" in EC2-VPC.

DeleteSnapshot(SnapshotId => Str, [DryRun => Bool])

Returns: nothing

Deletes the specified snapshot.

When you make periodic snapshots of a volume, the snapshots are incremental, and only the blocks on the device that have changed since your last snapshot are saved in the new snapshot. When you delete a snapshot, only the data not needed for any other snapshot is removed. So regardless of which prior snapshots have been deleted, all active snapshots will have access to all the information needed to restore the volume.

You cannot delete a snapshot of the root device of an EBS volume used by a registered AMI. You must first de-register the AMI before you can delete the snapshot.

For more information, see Deleting an Amazon EBS Snapshot in the Amazon Elastic Compute Cloud User Guide.

Returns: a Paws::EC2::DeleteVpcPeeringConnectionResult instance

Deletes a VPC peering connection. Either the owner of the requester VPC or the owner of the peer VPC can delete the VPC peering connection if it's in the "active" state. The owner of the requester VPC can delete a VPC peering connection in the "pending-acceptance" state.

DeleteVpnConnection(VpnConnectionId => Str, [DryRun => Bool])

Returns: nothing

Deletes the specified VPN connection.

If you're deleting the VPC and its associated components, we recommend that you detach the virtual private gateway from the VPC and delete the VPC before deleting the VPN connection. If you believe that the tunnel credentials for your VPN connection have been compromised, you can delete the VPN connection and create a new one that has new keys, without needing to delete the VPC or virtual private gateway. If you create a new VPN connection, you must reconfigure the customer gateway using the new configuration information returned with the new VPN connection ID.

DeleteVpnConnectionRoute(DestinationCidrBlock => Str, VpnConnectionId => Str)

Returns: nothing

Deletes the specified static route associated with a VPN connection between an existing virtual private gateway and a VPN customer gateway. The static route allows traffic to be routed from the virtual private gateway to the VPN customer gateway.

DeleteVpnGateway(VpnGatewayId => Str, [DryRun => Bool])

Returns: nothing

Deletes the specified virtual private gateway. We recommend that before you delete a virtual private gateway, you detach it from the VPC and delete the VPN connection. Note that you don't need to delete the virtual private gateway if you plan to delete and recreate the VPN connection between your VPC and your network.

DeregisterImage(ImageId => Str, [DryRun => Bool])

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

DescribeRouteTables([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], RouteTableIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeRouteTablesResult instance

Describes one or more of your route tables.

Each subnet in your VPC must be associated with a route table. If a subnet is not explicitly associated with any route table, it is implicitly associated with the main route table. This command does not return the subnet ID for implicit associations.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

DescribeSecurityGroups([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], GroupIds => ArrayRef[Str], GroupNames => ArrayRef[Str]])

DescribeSnapshotAttribute(Attribute => Str, SnapshotId => Str, [DryRun => Bool])

Returns: a Paws::EC2::DescribeSnapshotAttributeResult instance

Describes the specified attribute of the specified snapshot. You can specify only one attribute at a time.

For more information about EBS snapshots, see Amazon EBS Snapshots in the Amazon Elastic Compute Cloud User Guide.

DescribeSnapshots([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], MaxResults => Int, NextToken => Str, OwnerIds => ArrayRef[Str], RestorableByUserIds => ArrayRef[Str], SnapshotIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeSnapshotsResult instance

Describes one or more of the EBS snapshots available to you. Available snapshots include public snapshots available for any AWS account to launch, private snapshots that you own, and private snapshots owned by another AWS account but for which you've been given explicit create volume permissions.

The create volume permissions fall into the following categories:

• public: The owner of the snapshot granted create volume permissions for the snapshot to the "all" group. All AWS accounts have create volume permissions for these snapshots.
• explicit: The owner of the snapshot granted create volume permissions to a specific AWS account.
• implicit: An AWS account has implicit create volume permissions for all snapshots it owns.

The list of snapshots returned can be modified by specifying snapshot IDs, snapshot owners, or AWS accounts with create volume permissions. If no options are specified, Amazon EC2 returns all snapshots for which you have create volume permissions.

If you specify one or more snapshot IDs, only snapshots that have the specified IDs are returned. If you specify an invalid snapshot ID, an error is returned. If you specify a snapshot ID for which you do not have access, it is not included in the returned results.

If you specify one or more snapshot owners, only snapshots from the specified owners and for which you have access are returned. The results can include the AWS account IDs of the specified owners, "amazon" for snapshots owned by Amazon, or "self" for snapshots that you own.

If you specify a list of restorable users, only snapshots with create snapshot permissions for those users are returned. You can specify AWS account IDs (if you own the snapshots), "self" for snapshots for which you own or have explicit permissions, or "all" for public snapshots.

If you are describing a long list of snapshots, you can paginate the output to make the list more manageable. The "MaxResults" parameter sets the maximum number of results returned in a single page. If the list of results exceeds your "MaxResults" value, then that number of results is returned along with a "NextToken" value that can be passed to a subsequent "DescribeSnapshots" request to retrieve the remaining results.

For more information about EBS snapshots, see Amazon EBS Snapshots in the Amazon Elastic Compute Cloud User Guide.

DescribeSpotDatafeedSubscription([DryRun => Bool])

Returns: a Paws::EC2::DescribeSpotFleetRequestHistoryResponse instance

Describes the events for the specified Spot fleet request during the specified time.

Spot fleet events are delayed by up to 30 seconds before they can be described. This ensures that you can query by the last evaluated time and not miss a recorded event.

DescribeSpotFleetRequests([DryRun => Bool, MaxResults => Int, NextToken => Str, SpotFleetRequestIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeSpotFleetRequestsResponse instance

Describes your Spot fleet requests.

DescribeSpotInstanceRequests([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], SpotInstanceRequestIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeSpotInstanceRequestsResult instance

Describes the Spot Instance requests that belong to your account. Spot Instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot Price. Amazon EC2 periodically sets the Spot Price based on available Spot Instance capacity and current Spot Instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

You can use "DescribeSpotInstanceRequests" to find a running Spot Instance by examining the response. If the status of the Spot Instance is "fulfilled", the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances with a filter to look for instances where the instance lifecycle is "spot".

DescribeSpotPriceHistory([AvailabilityZone => Str, DryRun => Bool, EndTime => Str, Filters => ArrayRef[Paws::EC2::Filter], InstanceTypes => ArrayRef[Str], MaxResults => Int, NextToken => Str, ProductDescriptions => ArrayRef[Str], StartTime => Str])

Describes the Spot Price history. The prices returned are listed in chronological order, from the oldest to the most recent, for up to the past 90 days. For more information, see Spot Instance Pricing History in the Amazon Elastic Compute Cloud User Guide.

When you specify a start and end time, this operation returns the prices of the instance types within the time range that you specified and the time when the price changed. The price is valid within the time period that you specified; the response merely indicates the last time that the price changed.

DescribeSubnets([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], SubnetIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeSubnetsResult instance

Describes one or more of your subnets.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

DescribeVolumes([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], MaxResults => Int, NextToken => Str, VolumeIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeVolumesResult instance

Describes the specified EBS volumes.

If you are describing a long list of volumes, you can paginate the output to make the list more manageable. The "MaxResults" parameter sets the maximum number of results returned in a single page. If the list of results exceeds your "MaxResults" value, then that number of results is returned along with a "NextToken" value that can be passed to a subsequent "DescribeVolumes" request to retrieve the remaining results.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

DescribeVolumeStatus([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], MaxResults => Int, NextToken => Str, VolumeIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeVolumeStatusResult instance

Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The "DescribeVolumeStatus" operation provides the following information about the specified volumes:

Status: Reflects the current status of the volume. The possible values are "ok", "impaired" , "warning", or "insufficient-data". If all checks pass, the overall status of the volume is "ok". If the check fails, the overall status is "impaired". If the status is "insufficient-data", then the checks may still be taking place on your volume at the time. We recommend that you retry the request. For more information on volume status, see Monitoring the Status of Your Volumes.

Events: Reflect the cause of a volume status and may require you to take action. For example, if your volume returns an "impaired" status, then the volume event might be "potential-data-inconsistency". This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and may have inconsistent data.

Actions: Reflect the actions you may have to take in response to an event. For example, if the status of the volume is "impaired" and the volume event shows "potential-data-inconsistency", then the action shows "enable-volume-io". This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the "error" state (for example, when a volume is incapable of accepting I/O.)

DescribeVpcAttribute(VpcId => Str, [Attribute => Str, DryRun => Bool])

Returns: a Paws::EC2::DescribeVpcAttributeResult instance

Describes the specified attribute of the specified VPC. You can specify only one attribute at a time.

Describes one or more of your VPC peering connections.

DescribeVpcs([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], VpcIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeVpcsResult instance

Describes one or more of your VPCs.

DescribeVpnConnections([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], VpnConnectionIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeVpnConnectionsResult instance

Describes one or more of your VPN connections.

For more information about VPN connections, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

DescribeVpnGateways([DryRun => Bool, Filters => ArrayRef[Paws::EC2::Filter], VpnGatewayIds => ArrayRef[Str]])

Returns: a Paws::EC2::DescribeVpnGatewaysResult instance

Describes one or more of your virtual private gateways.

For more information about virtual private gateways, see Adding an IPsec Hardware VPN to Your VPC in the Amazon Virtual Private Cloud User Guide.

DetachClassicLinkVpc(InstanceId => Str, VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::DetachClassicLinkVpcResult instance

Unlinks (detaches) a linked EC2-Classic instance from a VPC. After the instance has been unlinked, the VPC security groups are no longer associated with it. An instance is automatically unlinked from a VPC when it's stopped.

DetachInternetGateway(InternetGatewayId => Str, VpcId => Str, [DryRun => Bool])

Returns: nothing

Detaches an Internet gateway from a VPC, disabling connectivity between the Internet and the VPC. The VPC must not contain any running instances with Elastic IP addresses.

DetachNetworkInterface(AttachmentId => Str, [DryRun => Bool, Force => Bool])

Returns: nothing

Detaches a network interface from an instance.

DetachVolume(VolumeId => Str, [Device => Str, DryRun => Bool, Force => Bool, InstanceId => Str])

Returns: a Paws::EC2::VolumeAttachment instance

Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume. Failure to do so results in the volume being stuck in a busy state while detaching.

If an Amazon EBS volume is the root device of an instance, it can't be detached while the instance is running. To detach the root volume, stop the instance first.

When a volume with an AWS Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

For more information, see Detaching an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

DetachVpnGateway(VpcId => Str, VpnGatewayId => Str, [DryRun => Bool])

Returns: nothing

Detaches a virtual private gateway from a VPC. You do this if you're planning to turn off the VPC and not use it anymore. You can confirm a virtual private gateway has been completely detached from a VPC by describing the virtual private gateway (any attachments to the virtual private gateway are also described).

You must wait for the attachment's state to switch to "detached" before you can delete the VPC or attach a different VPC to the virtual private gateway.

DisableVgwRoutePropagation(GatewayId => Str, RouteTableId => Str)

Returns: nothing

Disables a virtual private gateway (VGW) from propagating routes to a specified route table of a VPC.

DisableVpcClassicLink(VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::DisableVpcClassicLinkResult instance

Disables ClassicLink for a VPC. You cannot disable ClassicLink for a VPC that has EC2-Classic instances linked to it.

DisassociateAddress([AssociationId => Str, DryRun => Bool, PublicIp => Str])

Returns: nothing

Disassociates an Elastic IP address from the instance or network interface it's associated with.

An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

DisassociateRouteTable(AssociationId => Str, [DryRun => Bool])

Returns: nothing

Disassociates a subnet from a route table.

After you perform this action, the subnet no longer uses the routes in the route table. Instead, it uses the routes in the VPC's main route table. For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

EnableVgwRoutePropagation(GatewayId => Str, RouteTableId => Str)

Returns: nothing

Enables a virtual private gateway (VGW) to propagate routes to the specified route table of a VPC.

EnableVolumeIO(VolumeId => Str, [DryRun => Bool])

Returns: nothing

Enables I/O operations for a volume that had I/O operations disabled because the data on the volume was potentially inconsistent.

EnableVpcClassicLink(VpcId => Str, [DryRun => Bool])

Returns: a Paws::EC2::EnableVpcClassicLinkResult instance

Enables a VPC for ClassicLink. You can then link EC2-Classic instances to your ClassicLink-enabled VPC to allow communication over private IP addresses. You cannot enable your VPC for ClassicLink if any of your VPC's route tables have existing routes for address ranges within the "10.0.0.0/8" IP address range, excluding local routes for VPCs in the "10.0.0.0/16" and "10.1.0.0/16" IP address ranges. For more information, see ClassicLink in the Amazon Elastic Compute Cloud User Guide.

GetConsoleOutput(InstanceId => Str, [DryRun => Bool])

Returns: a Paws::EC2::GetConsoleOutputResult instance

Gets the console output for the specified instance.

Instances do not have a physical monitor through which you can view their console output. They also lack physical controls that allow you to power up, reboot, or shut them down. To allow these actions, we provide them through the Amazon EC2 API and command line interface.

Instance console output is buffered and posted shortly after instance boot, reboot, and termination. Amazon EC2 preserves the most recent 64 KB output which is available for at least one hour after the most recent post.

For Linux instances, the instance console output displays the exact console output that would normally be displayed on a physical monitor attached to a computer. This output is buffered because the instance produces it and then posts it to a store where the instance's owner can retrieve it.

For Windows instances, the instance console output includes output from the EC2Config service.

GetPasswordData(InstanceId => Str, [DryRun => Bool])

Returns: a Paws::EC2::GetPasswordDataResult instance

Retrieves the encrypted administrator password for an instance running Windows.

The Windows password is generated at boot if the "EC2Config" service plugin, "Ec2SetPassword", is enabled. This usually only happens the first time an AMI is launched, and then "Ec2SetPassword" is automatically disabled. The password is not generated for rebundled AMIs unless "Ec2SetPassword" is enabled before bundling.

The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.

Password generation and encryption takes a few moments. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

ImportImage([Architecture => Str, ClientData => Paws::EC2::ClientData, ClientToken => Str, Description => Str, DiskContainers => ArrayRef[Paws::EC2::ImageDiskContainer], DryRun => Bool, Hypervisor => Str, LicenseType => Str, Platform => Str, RoleName => Str])

Returns: a Paws::EC2::ImportImageResult instance

ImportInstance(Platform => Str, [Description => Str, DiskImages => ArrayRef[Paws::EC2::DiskImage], DryRun => Bool, LaunchSpecification => Paws::EC2::ImportInstanceLaunchSpecification])

Returns: a Paws::EC2::ImportInstanceResult instance

Creates an import instance task using metadata from the specified disk image. "ImportInstance" only supports single-volume VMs. To import multi-volume VMs, use ImportImage. After importing the image, you then upload it using the "ec2-import-volume" command in the EC2 command line tools. For more information, see Using the Command Line Tools to Import Your Virtual Machine to Amazon EC2 in the Amazon Elastic Compute Cloud User Guide.

ImportKeyPair(KeyName => Str, PublicKeyMaterial => Str, [DryRun => Bool])

Returns: a Paws::EC2::ImportKeyPairResult instance

Imports the public key from an RSA key pair that you created with a third-party tool. Compare this with CreateKeyPair, in which AWS creates the key pair and gives the keys to you (AWS keeps a copy of the public key). With ImportKeyPair, you create the key pair and give AWS just the public key. The private key is never transferred between you and AWS.

For more information about key pairs, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

ImportSnapshot([ClientData => Paws::EC2::ClientData, ClientToken => Str, Description => Str, DiskContainer => Paws::EC2::SnapshotDiskContainer, DryRun => Bool, RoleName => Str])

Returns: a Paws::EC2::ImportSnapshotResult instance

Imports a disk into an EBS snapshot.

ImportVolume(AvailabilityZone => Str, Image => Paws::EC2::DiskImageDetail, Volume => Paws::EC2::VolumeDetail, [Description => Str, DryRun => Bool])

Returns: a Paws::EC2::ImportVolumeResult instance

Creates an import volume task using metadata from the specified disk image. After importing the image, you then upload it using the "ec2-import-volume" command in the Amazon EC2 command-line interface (CLI) tools. For more information, see Using the Command Line Tools to Import Your Virtual Machine to Amazon EC2 in the Amazon Elastic Compute Cloud User Guide.

ModifyImageAttribute(ImageId => Str, [Attribute => Str, Description => Paws::EC2::AttributeValue, DryRun => Bool, LaunchPermission => Paws::EC2::LaunchPermissionModifications, OperationType => Str, ProductCodes => ArrayRef[Str], UserGroups => ArrayRef[Str], UserIds => ArrayRef[Str], Value => Str])

Returns: nothing

Modifies the specified attribute of the specified AMI. You can specify only one attribute at a time.

AWS Marketplace product codes cannot be modified. Images with an AWS Marketplace product code cannot be made public.

ModifyInstanceAttribute(InstanceId => Str, [Attribute => Str, BlockDeviceMappings => ArrayRef[Paws::EC2::InstanceBlockDeviceMappingSpecification], DisableApiTermination => Paws::EC2::AttributeBooleanValue, DryRun => Bool, EbsOptimized => Paws::EC2::AttributeBooleanValue, Groups => ArrayRef[Str], InstanceInitiatedShutdownBehavior => Paws::EC2::AttributeValue, InstanceType => Paws::EC2::AttributeValue, Kernel => Paws::EC2::AttributeValue, Ramdisk => Paws::EC2::AttributeValue, SourceDestCheck => Paws::EC2::AttributeBooleanValue, SriovNetSupport => Paws::EC2::AttributeValue, UserData => Paws::EC2::BlobAttributeValue, Value => Str])

Returns: nothing

Modifies the specified attribute of the specified instance. You can specify only one attribute at a time.

To modify some attributes, the instance must be stopped. For more information, see Modifying Attributes of a Stopped Instance in the Amazon Elastic Compute Cloud User Guide.

Returns: a Paws::EC2::ModifyReservedInstancesResult instance

Modifies the Availability Zone, instance count, instance type, or network platform (EC2-Classic or EC2-VPC) of your Reserved Instances. The Reserved Instances to be modified must be identical, except for Availability Zone, network platform, and instance type.

For more information, see Modifying Reserved Instances in the Amazon Elastic Compute Cloud User Guide.

ModifySnapshotAttribute(SnapshotId => Str, [Attribute => Str, CreateVolumePermission => Paws::EC2::CreateVolumePermissionModifications, DryRun => Bool, GroupNames => ArrayRef[Str], OperationType => Str, UserIds => ArrayRef[Str]])

Returns: nothing

Adds or removes permission settings for the specified snapshot. You may add or remove specified AWS account IDs from a snapshot's list of create volume permissions, but you cannot do both in a single API call. If you need to both add and remove account IDs for a snapshot, you must use multiple API calls.

For more information on modifying snapshot permissions, see Sharing Snapshots in the Amazon Elastic Compute Cloud User Guide.

Snapshots with AWS Marketplace product codes cannot be made public.

ModifySubnetAttribute(SubnetId => Str, [MapPublicIpOnLaunch => Paws::EC2::AttributeBooleanValue])

Returns: nothing

Modifies a subnet attribute.

ModifyVolumeAttribute(VolumeId => Str, [AutoEnableIO => Paws::EC2::AttributeBooleanValue, DryRun => Bool])

Returns: nothing

Modifies a volume attribute.

By default, all I/O operations for the volume are suspended when the data on the volume is determined to be potentially inconsistent, to prevent undetectable, latent data corruption. The I/O access to the volume can be resumed by first enabling I/O access and then checking the data consistency on your volume.

You can change the default behavior to resume I/O operations. We recommend that you change this only for boot volumes or for volumes that are stateless or disposable.

ModifyVpcAttribute(VpcId => Str, [EnableDnsHostnames => Paws::EC2::AttributeBooleanValue, EnableDnsSupport => Paws::EC2::AttributeBooleanValue])

Returns: nothing

Modifies the specified attribute of the specified VPC.

Returns: a Paws::EC2::ModifyVpcEndpointResult instance

Modifies attributes of a specified VPC endpoint. You can modify the policy associated with the endpoint, and you can add and remove route tables associated with the endpoint.

MonitorInstances(InstanceIds => ArrayRef[Str], [DryRun => Bool])

Returns: a Paws::EC2::MonitorInstancesResult instance

Enables monitoring for a running instance. For more information about monitoring instances, see Monitoring Your Instances and Volumes in the Amazon Elastic Compute Cloud User Guide.

MoveAddressToVpc(PublicIp => Str, [DryRun => Bool])

Returns: a Paws::EC2::MoveAddressToVpcResult instance

Moves an Elastic IP address from the EC2-Classic platform to the EC2-VPC platform. The Elastic IP address must be allocated to your account, and it must not be associated with an instance. After the Elastic IP address is moved, it is no longer available for use in the EC2-Classic platform, unless you move it back using the RestoreAddressToClassic request. You cannot move an Elastic IP address that's allocated for use in the EC2-VPC platform to the EC2-Classic platform.

PurchaseReservedInstancesOffering(InstanceCount => Int, ReservedInstancesOfferingId => Str, [DryRun => Bool, LimitPrice => Paws::EC2::ReservedInstanceLimitPrice])

Returns: a Paws::EC2::PurchaseReservedInstancesOfferingResult instance

Purchases a Reserved Instance for use with your account. With Amazon EC2 Reserved Instances, you obtain a capacity reservation for a certain instance configuration over a specified period of time and pay a lower hourly rate compared to on-Demand Instance pricing.

Use DescribeReservedInstancesOfferings to get a list of Reserved Instance offerings that match your specifications. After you've purchased a Reserved Instance, you can check for your new Reserved Instance with DescribeReservedInstances.

For more information, see Reserved Instances and Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

RebootInstances(InstanceIds => ArrayRef[Str], [DryRun => Bool])

Returns: nothing

Requests a reboot of one or more instances. This operation is asynchronous; it only queues a request to reboot the specified instances. The operation succeeds if the instances are valid and belong to you. Requests to reboot terminated instances are ignored.

If a Linux/Unix instance does not cleanly shut down within four minutes, Amazon EC2 performs a hard reboot.

For more information about troubleshooting, see Getting Console Output and Rebooting Instances in the Amazon Elastic Compute Cloud User Guide.

RegisterImage(Name => Str, [Architecture => Str, BlockDeviceMappings => ArrayRef[Paws::EC2::BlockDeviceMapping], Description => Str, DryRun => Bool, ImageLocation => Str, KernelId => Str, RamdiskId => Str, RootDeviceName => Str, SriovNetSupport => Str, VirtualizationType => Str])

Returns: a Paws::EC2::RegisterImageResult instance

Registers an AMI. When you're creating an AMI, this is the final step you must complete before you can launch an instance from the AMI. This step is required if you're creating an instance store-backed Linux or Windows AMI. For more information, see Creating an Instance Store-Backed Linux AMI and Creating an Instance Store-Backed Windows AMI in the Amazon Elastic Compute Cloud User Guide.

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don't have to register the AMI yourself.

You can also use "RegisterImage" to create an Amazon EBS-backed AMI from a snapshot of a root device volume. For more information, see Launching an Instance from a Backup in the Amazon Elastic Compute Cloud User Guide. Note that although you can create a Windows AMI from a snapshot, you can't launch an instance from the AMI - use the CreateImage command instead.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

You can't register an image where a secondary (non-root) snapshot has AWS Marketplace product codes.

RejectVpcPeeringConnection(VpcPeeringConnectionId => Str, [DryRun => Bool])

Returns: a Paws::EC2::RejectVpcPeeringConnectionResult instance

Rejects a VPC peering connection request. The VPC peering connection must be in the "pending-acceptance" state. Use the DescribeVpcPeeringConnections request to view your outstanding VPC peering connection requests. To delete an active VPC peering connection, or to delete a VPC peering connection request that you initiated, use DeleteVpcPeeringConnection.

ReleaseAddress([AllocationId => Str, DryRun => Bool, PublicIp => Str])

Returns: nothing

Releases the specified Elastic IP address.

After releasing an Elastic IP address, it is released to the IP address pool and might be unavailable to you. Be sure to update your DNS records and any servers or devices that communicate with the address. If you attempt to release an Elastic IP address that you already released, you'll get an "AuthFailure" error if the address is already allocated to another AWS account.

[EC2-Classic, default VPC] Releasing an Elastic IP address automatically disassociates it from any instance that it's associated with. To disassociate an Elastic IP address without releasing it, use DisassociateAddress.

[Nondefault VPC] You must use DisassociateAddress to disassociate the Elastic IP address before you try to release it. Otherwise, Amazon EC2 returns an error ("InvalidIPAddress.InUse").

ReplaceNetworkAclAssociation(AssociationId => Str, NetworkAclId => Str, [DryRun => Bool])

Returns: a Paws::EC2::ReplaceNetworkAclAssociationResult instance

Changes which network ACL a subnet is associated with. By default when you create a subnet, it's automatically associated with the default network ACL. For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

ReplaceNetworkAclEntry(CidrBlock => Str, Egress => Bool, NetworkAclId => Str, Protocol => Str, RuleAction => Str, RuleNumber => Int, [DryRun => Bool, IcmpTypeCode => Paws::EC2::IcmpTypeCode, PortRange => Paws::EC2::PortRange])

Returns: nothing

Replaces an entry (rule) in a network ACL. For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

ReplaceRoute(DestinationCidrBlock => Str, RouteTableId => Str, [DryRun => Bool, GatewayId => Str, InstanceId => Str, NetworkInterfaceId => Str, VpcPeeringConnectionId => Str])

Returns: nothing

Replaces an existing route within a route table in a VPC. You must provide only one of the following: Internet gateway or virtual private gateway, NAT instance, VPC peering connection, or network interface.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

ReplaceRouteTableAssociation(AssociationId => Str, RouteTableId => Str, [DryRun => Bool])

Returns: a Paws::EC2::ReplaceRouteTableAssociationResult instance

Changes the route table associated with a given subnet in a VPC. After the operation completes, the subnet uses the routes in the new route table it's associated with. For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

You can also use ReplaceRouteTableAssociation to change which table is the main route table in the VPC. You just specify the main route table's association ID and the route table to be the new main route table.

ReportInstanceStatus(Instances => ArrayRef[Str], ReasonCodes => ArrayRef[Str], Status => Str, [Description => Str, DryRun => Bool, EndTime => Str, StartTime => Str])

Returns: nothing

Submits feedback about the status of an instance. The instance must be in the "running" state. If your experience with the instance differs from the instance status returned by DescribeInstanceStatus, use ReportInstanceStatus to report your experience with the instance. Amazon EC2 collects this information to improve the accuracy of status checks.

Use of this action does not change the value returned by DescribeInstanceStatus.

RequestSpotFleet(SpotFleetRequestConfig => Paws::EC2::SpotFleetRequestConfigData, [DryRun => Bool])

Returns: a Paws::EC2::RequestSpotFleetResponse instance

Creates a Spot fleet request.

For more information, see Spot Fleets in the Amazon Elastic Compute Cloud User Guide.

RequestSpotInstances(SpotPrice => Str, [AvailabilityZoneGroup => Str, ClientToken => Str, DryRun => Bool, InstanceCount => Int, LaunchGroup => Str, LaunchSpecification => Paws::EC2::RequestSpotLaunchSpecification, Type => Str, ValidFrom => Str, ValidUntil => Str])

Returns: a Paws::EC2::RequestSpotInstancesResult instance

Creates a Spot Instance request. Spot Instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot Price. Amazon EC2 periodically sets the Spot Price based on available Spot Instance capacity and current Spot Instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

ResetImageAttribute(Attribute => Str, ImageId => Str, [DryRun => Bool])

Returns: nothing

Resets an attribute of an AMI to its default value.

The productCodes attribute can't be reset.

ResetInstanceAttribute(Attribute => Str, InstanceId => Str, [DryRun => Bool])

Returns: nothing

Resets an attribute of an instance to its default value. To reset the "kernel" or "ramdisk", the instance must be in a stopped state. To reset the "SourceDestCheck", the instance can be either running or stopped.

The "SourceDestCheck" attribute controls whether source/destination checking is enabled. The default value is "true", which means checking is enabled. This value must be "false" for a NAT instance to perform NAT. For more information, see NAT Instances in the Amazon Virtual Private Cloud User Guide.

ResetNetworkInterfaceAttribute(NetworkInterfaceId => Str, [DryRun => Bool, SourceDestCheck => Str])

Returns: nothing

Resets a network interface attribute. You can specify only one attribute at a time.

ResetSnapshotAttribute(Attribute => Str, SnapshotId => Str, [DryRun => Bool])

Returns: nothing

Resets permission settings for the specified snapshot.

For more information on modifying snapshot permissions, see Sharing Snapshots in the Amazon Elastic Compute Cloud User Guide.

RestoreAddressToClassic(PublicIp => Str, [DryRun => Bool])

Returns: a Paws::EC2::RestoreAddressToClassicResult instance

Restores an Elastic IP address that was previously moved to the EC2-VPC platform back to the EC2-Classic platform. You cannot move an Elastic IP address that was originally allocated for use in EC2-VPC. The Elastic IP address must not be associated with an instance or network interface.

RevokeSecurityGroupEgress(GroupId => Str, [CidrIp => Str, DryRun => Bool, FromPort => Int, IpPermissions => ArrayRef[Paws::EC2::IpPermission], IpProtocol => Str, SourceSecurityGroupName => Str, SourceSecurityGroupOwnerId => Str, ToPort => Int])

Returns: nothing

Removes one or more egress rules from a security group for EC2-VPC. The values that you specify in the revoke request (for example, ports) must match the existing rule's values for the rule to be revoked.

Each rule consists of the protocol and the CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

RevokeSecurityGroupIngress([CidrIp => Str, DryRun => Bool, FromPort => Int, GroupId => Str, GroupName => Str, IpPermissions => ArrayRef[Paws::EC2::IpPermission], IpProtocol => Str, SourceSecurityGroupName => Str, SourceSecurityGroupOwnerId => Str, ToPort => Int])

Returns: nothing

Removes one or more ingress rules from a security group. The values that you specify in the revoke request (for example, ports) must match the existing rule's values for the rule to be removed.

Each rule consists of the protocol and the CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

RunInstances(ImageId => Str, MaxCount => Int, MinCount => Int, [AdditionalInfo => Str, BlockDeviceMappings => ArrayRef[Paws::EC2::BlockDeviceMapping], ClientToken => Str, DisableApiTermination => Bool, DryRun => Bool, EbsOptimized => Bool, IamInstanceProfile => Paws::EC2::IamInstanceProfileSpecification, InstanceInitiatedShutdownBehavior => Str, InstanceType => Str, KernelId => Str, KeyName => Str, Monitoring => Paws::EC2::RunInstancesMonitoringEnabled, NetworkInterfaces => ArrayRef[Paws::EC2::InstanceNetworkInterfaceSpecification], Placement => Paws::EC2::Placement, PrivateIpAddress => Str, RamdiskId => Str, SecurityGroupIds => ArrayRef[Str], SecurityGroups => ArrayRef[Str], SubnetId => Str, UserData => Str])

Returns: a Paws::EC2::Reservation instance

Launches the specified number of instances using an AMI for which you have permissions.

When you launch an instance, it enters the "pending" state. After the instance is ready for you, it enters the "running" state. To check the state of your instance, call DescribeInstances.

If you don't specify a security group when launching an instance, Amazon EC2 uses the default security group. For more information, see Security Groups in the Amazon Elastic Compute Cloud User Guide.

Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

You can provide optional user data when launching an instance. For more information, see Instance Metadata in the Amazon Elastic Compute Cloud User Guide.

If any of the AMIs have a product code attached for which the user has not subscribed, "RunInstances" fails.

T2 instance types can only be launched into a VPC. If you do not have a default VPC, or if you do not specify a subnet ID in the request, "RunInstances" fails.

For more information about troubleshooting, see What To Do If An Instance Immediately Terminates, and Troubleshooting Connecting to Your Instance in the Amazon Elastic Compute Cloud User Guide.

StartInstances(InstanceIds => ArrayRef[Str], [AdditionalInfo => Str, DryRun => Bool])

Returns: a Paws::EC2::StartInstancesResult instance

Starts an Amazon EBS-backed AMI that you've previously stopped.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

For more information, see Stopping Instances in the Amazon Elastic Compute Cloud User Guide.

StopInstances(InstanceIds => ArrayRef[Str], [DryRun => Bool, Force => Bool])

Returns: a Paws::EC2::StopInstancesResult instance

Stops an Amazon EBS-backed instance. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

You can't start or stop Spot Instances.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

For more information about troubleshooting, see Troubleshooting Stopping Your Instance in the Amazon Elastic Compute Cloud User Guide.

TerminateInstances(InstanceIds => ArrayRef[Str], [DryRun => Bool])

Returns: a Paws::EC2::TerminateInstancesResult instance

Shuts down one or more instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds.

Terminated instances remain visible after termination (for approximately one hour).

By default, Amazon EC2 deletes all EBS volumes that were attached when the instance launched. Volumes attached after instance launch continue running.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

For more information about troubleshooting, see Troubleshooting Terminating Your Instance in the Amazon Elastic Compute Cloud User Guide.

UnassignPrivateIpAddresses(NetworkInterfaceId => Str, PrivateIpAddresses => ArrayRef[Str])

Returns: nothing

Unassigns one or more secondary private IP addresses from a network interface.

UnmonitorInstances(InstanceIds => ArrayRef[Str], [DryRun => Bool])

Returns: a Paws::EC2::UnmonitorInstancesResult instance

Disables monitoring for a running instance. For more information about monitoring instances, see Monitoring Your Instances and Volumes in the Amazon Elastic Compute Cloud User Guide.
