Explanation:
AWS Cloudformation is an application management tool which provides application modelling,
deployment, configuration, management and related activities. AWS CloudFormation introduces
two concepts: the template and the stack. The template is a JSON-format, text-based file that
describes all the AWS resources required to deploy and run an application. The stack is a
collection of AWS resources which are created and managed as a single unit when AWS
CloudFormation instantiates a template. While creating a stack, the user uploads the template and
provides the data for the parameters if required.
