Amazon CloudFormation provides a common language for you to model and provision Amazon Web Services and third party application resources in your cloud environment. CloudFormation allows you to use programming languages or a simple text file to model and provision, in an automated and secure manner, all the resources needed for your applications across all regions and accounts. This gives you a single source of truth for your Amazon Web Services and non- Amazon Web Services resources.
Model it all
Amazon CloudFormation allows you to model your entire infrastructure and application resources with either a text file or programming languages. The CloudFormation Registry makes it easy to manage third party resources with CloudFormation. This provides a single source of truth for all your resources and helps you to standardize infrastructure components used across your organization, enabling configuration compliance and faster troubleshooting.
Automate and deploy
Amazon CloudFormation provisions your Amazon Web Services and third party resources in a safe, repeatable manner, allowing you to build and rebuild your infrastructure and applications, without having to perform manual actions or write custom scripts. CloudFormation takes care of determining the right operations to perform when managing your stack, orchestrating them in the most efficient way, and rolls back changes automatically if errors are detected.
It's just code
Codifying your infrastructure allows you to treat your infrastructure as just code. You can author it with any code editor, check it into a version control system, and review the files with team members before deploying into production.
