One of the methods which provide a way for you to quickly identify when a deployment has failed, and then to optionally roll back the failure to the last working deployment.
When the alarms are generated, Amazon ECS sets the service deployment to failed. Set the rollback parameter to have Amazon ECS to roll back your service to the last completed deployment after a failure.
