AWS CloudFormation Documentation

AWS CloudFormation gives you a way to model a collection of related AWS and third-party resources, provision them quickly and consistently, and manage them throughout their lifecycles, by treating infrastructure as code. A CloudFormation template describes your desired resources and their dependencies so you can launch and configure them together as a stack. You can use a template to create, update, and delete an entire stack as a single unit, as often as you need to, instead of managing resources individually. You can manage and provision stacks across multiple AWS accounts and AWS Regions.

Using the AWS CloudFormation Registry, you can model and provision third-party resources.

You can build your own resource providers using the AWS CloudFormation CLI, an open-source tool that streamlines the development process, including local testing and code generation capabilities.

CloudFormation let you provision a common set of AWS resources across multiple accounts and regions.

CloudFormation allows you to model your cloud environment in text files. You can use open-source declarative languages, such as JSON or YAML, to describe what AWS resources you want to create and configure.

With the AWS Cloud Development Kit (AWS CDK), you can define your cloud environment using familiar programming languages, and then provision your infrastructure using CloudFormation directly from your IDE. 

You can build serverless applications with the AWS Serverless Application Model (SAM), an open-source framework that provides shorthand syntax to express functions, APIs, databases, and event source mappings. 

CloudFormation automates provisioning and updating your infrastructure in a controlled manner. You can use Rollback Triggers to specify the CloudWatch alarms that CloudFormation should monitor during the stack creation and update process. 

AWS CloudFormation allows you to preview how proposed changes to a stack might affect your running resources, for example to check whether your changes will delete or replace any particular resources.  

AWS CloudFormation manages dependencies between your resources during stack management actions. CloudFormation supports determining the correct sequence of actions to take for each resource when performing stack operations.
