AWS CloudFormation is a service that helps you model and set up your AWS resources using Infrastructure as Code (IaC). It solves several key problems:

• Manual Configuration Errors: Eliminates human error in manual resource provisioning
• Environment Consistency: Ensures identical infrastructure across development, testing, and production
• Resource Dependencies: Automatically handles the order of resource creation and dependencies
• Version Control: Infrastructure changes can be tracked and versioned like application code
• Rollback Capabilities: Provides automatic rollback if stack creation/update fails
• Cost Management: Easy to tear down entire environments, reducing costs
• Documentation: Templates serve as living documentation of your infrastructure
