Container for the parameters to the TerminateInstances operation. 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 protectedInstance B:
us-east-1a; Not protectedInstance C:
us-east-1b; ProtectedInstance 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-1aare 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.
By default, the TerminateInstances operation includes a graceful operating system
(OS) shutdown. To bypass the graceful shutdown, use the skipOsShutdown parameter;
however, this might risk data integrity.
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 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 Amazon
EC2 instance state changes in the Amazon EC2 User Guide.
When you terminate an instance, we attempt to terminate it forcibly after a short while. If your instance appears stuck in the shutting-down state after a period of time, there might be an issue with the underlying host computer. For more information about terminating and troubleshooting terminating your instances, see Terminate Amazon EC2 instances and Troubleshooting terminating your instance in the Amazon EC2 User Guide.

The TerminateInstancesRequest type exposes the following members
Constructors
| Name | Description | |
|---|---|---|
|
TerminateInstancesRequest() |
Empty constructor used to set properties independently even when a simple constructor is available |
|
|
TerminateInstancesRequest(List<String>) |
Instantiates TerminateInstancesRequest with the parameterized properties |
Properties
| Name | Type | Description | |
|---|---|---|---|
|
|
Force | System.Boolean |
Gets and sets the property Force. Forces the instances to terminate. The instance will first attempt a graceful shutdown, which includes flushing file system caches and metadata. If the graceful shutdown fails to complete within the timeout period, the instance shuts down forcibly without flushing the file system caches and metadata. |
|
|
InstanceIds | System.Collections.Generic.List<System.String> |
Gets and sets the property InstanceIds. The IDs of the instances. Constraints: Up to 1000 instance IDs. We recommend breaking up this request into smaller batches. |
|
|
SkipOsShutdown | System.Boolean |
Gets and sets the property SkipOsShutdown. Specifies whether to bypass the graceful OS shutdown process when the instance is terminated.
Default: |
Examples
This example terminates the specified EC2 instance.
To terminate an EC2 instance
var client = new AmazonEC2Client();
var response = client.TerminateInstances(new TerminateInstancesRequest
{
InstanceIds = new List<string> {
"i-1234567890abcdef0"
}
});
List<InstanceStateChange> terminatingInstances = response.TerminatingInstances;
