Parallel Stack Processing and Nested Stack Updates for AWS CloudFormation

AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion by using custom or predefined templates.
