Initiate a Spot Instance interruption

You can select a Spot Instance request or a Spot Fleet request in the Amazon EC2 console and initiate a Spot Instance interruption so that you can test how the applications on your Spot Instances handle being interrupted. When you initiate a Spot Instance interruption, Amazon EC2 notifies you that your Spot Instance will be interrupted in two minutes, and then, after two minutes, the instance is interrupted.

The underlying service that performs the Spot Instance interruption is AWS Fault Injection Service (AWS FIS). For information about AWS FIS, see AWS Fault Injection Service.

Note

Interruption behaviors are terminate, stop, and hibernate. If you set the interruption behavior to hibernate, when you initiate a Spot Instance interruption, the hibernation process will begin immediately.

Initiating a Spot Instance interruption is supported in all AWS Regions except Asia Pacific (Jakarta), Asia Pacific (Osaka), China (Beijing), China (Ningxia), and Middle East (UAE).

Initiate a Spot Instance interruption

You can use the EC2 console to quickly initiate a Spot Instance interruption. When you select a Spot Instance request, you can initiate the interruption of one Spot Instance. When you select a Spot Fleet request, you can initiate the interruption of multiple Spot Instances at once.

For more advanced experiments to test Spot Instance interruptions, you can create your own experiments using the AWS FIS console.

To initiate the interruption of one Spot Instance in a Spot Instance request using the EC2 console

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the navigation pane, choose Spot Requests.

  3. Select a Spot Instance request, and then choose Actions, Initiate interruption. You can’t select multiple Spot Instance requests to initiate an interruption.

  4. In the Initiate Spot Instance interruption dialog box, under Service access, either use the default role, or choose an existing role. To choose an existing role, choose Use an existing service role, and then, for IAM role, select the role to use.

  5. When you're ready to initiate the Spot Instance interruption, choose Initiate interruption.

To initiate the interruption of one or more Spot Instances in a Spot Fleet request using the EC2 console

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the navigation pane, choose Spot Requests.

  3. Select a Spot Fleet request, and then choose Actions, Initiate interruption. You can’t select multiple Spot Fleet requests to initiate an interruption.

  4. In the Specify number of Spot Instances dialog box, for Number of instances to interrupt, enter the number of Spot Instances to interrupt, and then choose Confirm.

    Note

    The number can't exceed the number of Spot Instances in the fleet or your quota for the number of Spot Instances that AWS FIS can interrupt per experiment.

  5. In the Initiate Spot Instance interruption dialog box, under Service access, either use the default role, or choose an existing role. To choose an existing role, choose Use an existing service role, and then, for IAM role, select the role to use.

  6. When you're ready to initiate the Spot Instance interruption, choose Initiate interruption.

To create more advanced experiments to test Spot Instance interruptions using the AWS FIS console

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the navigation pane, choose Spot Requests.

  3. Choose Actions, Create advanced experiments.

    The AWS FIS console opens. For more information, see Tutorial: Test Spot Instance interruptions using AWS FIS in the AWS Fault Injection Service User Guide.

Verify the Spot Instance interruption

After you initiate the interruption, the following occurs:

To verify that the instance was interrupted after you initiated the interruption

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the navigation pane, open Spot Requests and Instances in separate browser tabs or windows.

  3. For Spot Requests, select the Spot Instance request or Spot Fleet request. The initial status is fulfilled. After the instance is interrupted, the status changes as follows, depending on the interruption behavior:

    • terminate – The status changes to instance-terminated-by-experiment.

    • stop – The status changes to marked-for-stop-by-experiment and then instance-stopped-by-experiment.

  4. For Instances, select the Spot Instance. The initial status is Running. Two minutes after you receive the Spot Instance interruption notice, the status changes as follows, depending on the interruption behavior:

    • stop – The status changes to Stopping and then Stopped.

    • terminate – The status changes to Shutting-down and then Terminated.

Quotas

Your AWS account has the following default quota for the number of Spot Instances that AWS FIS can interrupt per experiment.

Name Default Adjustable Description

Target SpotInstances for aws:ec2:send-spot-instance-interruptions

Each supported Region: 5

 Yes

The maximum number of Spot Instances that aws:ec2:send-spot-instance-interruptions can target when you identify targets using tags, per experiment.

You can request a quota increase. For more information, see Requesting a quota increase in the Service Quotas User Guide.

To view all the quotas for AWS FIS, open the Service Quotas console. In the navigation pane, choose AWS services and select AWS Fault Injection Service. You can also view all the quotas for AWS Fault Injection Service in the AWS Fault Injection Service User Guide.
