AWS CloudFormation

AWS CloudFormation automates resource provisioning through declarative YAML or JSON templates.

CloudFormation treats your infrastructure as code: it manages the entire lifecycle of AWS resources from Amazon EC2 instances to complex VPC configurations. You define your stack in a single template (JSON or YAML) and let the engine handle resource dependencies and parallel execution. It provides a reliable safety net: if a deployment fails, the service automatically rolls back to the last stable state. This eliminates manual configuration errors and ensures consistency across development, staging, and production environments.
