outdatedInstancesStrategy

Indicates what happens when new Amazon EC2 instances are launched mid-deployment and do not receive the deployed application revision.

If this option is set to UPDATE or is unspecified, CodeDeploy initiates one or more 'auto-update outdated instances' deployments to apply the deployed application revision to the new Amazon EC2 instances.

If this option is set to IGNORE, CodeDeploy does not initiate a deployment to update the new Amazon EC2 instances. This may result in instances having different revisions.
