Monitor and React to Deployment Changes in AWS CodeDeploy with Amazon CloudWatch Events

You can now monitor and automatically react to changes in your AWS CodeDeploy deployments using Amazon CloudWatch Events. This lets you detect changes in the state of an Amazon EC2 instance or deployment managed by CodeDeploy, and then invoke an action based on rules that you set. This is useful for building workflows and processes that are triggered by changes in your deployments.
