Create an AMI and cross-Region copy - AWS Systems Manager

Create an AMI and cross-Region copy

Creating an Amazon Machine Image (AMI) of an instance is a common process used in backup and recovery. You might also choose to copy an AMI to another Region as part of a disaster recovery architecture. Automating common maintenance tasks can reduce downtime if an issue requires failover. AWS Systems Manager Automation actions can help you accomplish this.

The following sample AWS Systems Manager Automation document below performs these actions.

  • Uses the aws:executeAwsApi Automation action to create an AMI.

  • Uses the aws:waitForAwsResourceProperty Automation action to confirm the availability of the AMI.

  • Uses the aws:executeScript Automation action to copy the AMI to the destination Region.
