EC2 Terminate Instances

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

If you specify multiple instances and the request fails (for example, because of a single incorrect instance ID), none of the instances are terminated.

If you terminate multiple instances across multiple Availability Zones, and one or more of the specified instances are enabled for termination protection, the request fails with the following results:

• The specified instances that are in the same Availability Zone as the protected instance are not terminated.

• The specified instances that are in different Availability Zones, where no other specified instances are protected, are successfully terminated.

For example, say you have the following instances:

• Instance A: us-east-1a; Not protected

• Instance B: us-east-1a; Not protected

• Instance C: us-east-1b; Protected

• Instance D: us-east-1b; not protected

If you attempt to terminate all of these instances in the same request, the request reports failure with the following results:

• Instance A and Instance B are successfully terminated because none of the specified instances in us-east-1a are enabled for termination protection.

• Instance C and Instance D fail to terminate because at least one of the specified instances in us-east-1b (Instance C) is enabled for termination protection.

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, any attached EBS volumes with the DeleteOnTermination block device mapping parameter set to true are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance lifecycle in the Amazon EC2 User Guide.

Basic Parameters

Parameter	Description
AWS Region(s)	Enter the desired AWS Region(s).To execute the action in multiple regions, provide a comma-separated list.For example: us-east-1,eu-west-2.If you wish to run the action in all available regions, use the asterisk symbol (*) instead.
Instance IDs	The IDs of the instances.Constraints: Up to 1000 instance IDs. We recommend breaking up this request into smaller batches.

Advanced Parameters

Parameter	Description
Disable XML To JSON Auto Convert	When checked, XML responses are not automatically converted into JSON format.
Dry Run	Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
