// AWS CloudFormation enables you to create and manage AWS infrastructure deployments
// predictably and repeatedly. AWS CloudFormation helps you leverage AWS products
// such as Amazon EC2, EBS, Amazon SNS, ELB, and Auto Scaling to build highly-reliable,
// highly scalable, cost effective applications without worrying about creating
// and configuring the underlying AWS infrastructure.
//
// With AWS CloudFormation, you declare all of your resources and dependencies
// in a template file. The template defines a collection of resources as a single
// unit called a stack. AWS CloudFormation creates and deletes all member resources
// of the stack together and manages all dependencies between the resources
// for you.
//
// For more information about this product, go to the CloudFormation Product
// Page (http://aws.amazon.com/cloudformation/).
//
// Amazon CloudFormation makes use of other AWS products. If you need additional
// technical information about a specific AWS product, you can find the product's
// technical documentation at http://docs.aws.amazon.com/documentation/ (http://docs.aws.amazon.com/documentation/).
