  title: AWS CloudFormation Templates API
  description: AWS CloudFormation gives you an easy way to model a collection of related AWS and third-party resources, provision them quickly and consistently, and manage them throughout their lifecycles. It uses templates to define stacks of resources and provides API operations for creating, updating, and deleting stacks. The API uses a query-style interface where all operations are submitted as POST requests with an Action parameter.
