Working with Application Revisions for AWS CodeDeploy

In AWS CodeDeploy, a revision contains a version of the source files AWS CodeDeploy will deploy to your instances or scripts AWS CodeDeploy will run on your instances.

You plan the revision, add an AppSpec file to the revision, and then push the revision to Amazon S3 or GitHub. After you push the revision, you can deploy it.
