CloudFormation

AWS CloudFormation allows customer to write infrastructure as a code. It provides an easy way to developers and system administrator to create and manage the collection of AWS resources as a single stack. It allows for the definition of an entire application stack to exist as either a single or set of text-based template files. A version controlled system can then be used to manage different versions of the application infrastructure. CloudFormation template helps customers to quickly and consistently build the stack for different environments. The CloudFormation also offers real-time audit logs of events that can occur during the deployment process of the stack. By defining the stack policies, you can prevent unauthorized access to the CloudFormation stack resources. It is tightly integrated in the AWS platform and almost all the services can be created using CloudFormation.
