Enable EBS optimization for an Amazon EC2 instance - Amazon Elastic Compute Cloud

Enable EBS optimization for an Amazon EC2 instance

You can manually enable EBS optimization only for previous generation instances types that optionally support EBS optimization. If you enable EBS optimization for these instance types, there is an additional hourly fee

Prerequisites

  • Verify that the instance type requires that you enable EBS optimization. For more information, see EBS optimization supported.

  • To enable EBS optimization after launch, you must stop the instance.

    Warning

    When you stop an instance, the data on instance store volumes is lost. To preserve this data, back it up to persistent storage.

Console
To enable Amazon EBS optimization during launch

In the Launch instances wizard, select the required instance type. Expand the Advanced details section, then for EBS-optimized instance, select Enable.

If the selected instance type does not support Amazon EBS optimization, the drop-down is disabled. If the instance type is Amazon EBS-optimized by default, Enable is already selected.

To enable Amazon EBS optimization after launch

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

  2. In the navigation pane, choose Instances, and select the instance.

  3. Stop the instance. Choose Actions, Instance state, Stop instance.

  4. With the instance still selected, choose Actions, Instance settings, Change instance type.

  5. Select EBS-optimized and then choose Apply.

    If the instance type is Amazon EBS-optimized by default, or if it does not support Amazon EBS optimization, the checkbox is disabled.

  6. Restart the instance. Choose Instance state, Start instance.

AWS CLI
To enable Amazon EBS optimization during launch

Use the run-instances command with the --ebs-optimized option.

To enable Amazon EBS optimization after launch

  1. If the instance is running, stop it by using the stop-instances command.

    aws ec2 stop-instances --instance-ids i-1234567890abcdef0

  2. Enable EBS optimization by using the modify-instance-attribute command with the --ebs-optimized option.

    aws ec2 modify-instance-attribute \
    --instance-id i-1234567890abcdef0 \
    --ebs-optimized
PowerShell
To enable Amazon EBS optimization during launch

Use the New-EC2Instance cmdlet with the -EbsOptimized option.

To enable Amazon EBS optimization after launch

  1. If the instance is running, stop it by using the Stop-EC2Instance cmdlet.

    Stop-EC2Instance -InstanceId i-1234567890abcdef0

  2. Enable EBS optimization by using the Edit-EC2InstanceAttribute cmdlet with the -EbsOptimized option.

    Edit-EC2InstanceAttribute `
    -InstanceId i-1234567890abcdef0 `
    -EbsOptimized $true
