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.

When you use AWS CloudFormation, you work with templates and stacks. You create template to describes your AWS resources and their properties.

CloudFormation has two parts: templates and stacks. A template is a JavaScript Object Notation (JSON) text file. The file, which is declarative and not scripted, defines what AWS resources or non-AWS resources are required to run the application.

Your CloudFormation templates templates can live with your application in your version control repository, allowing architectures to be reused
