Validate Your Lambda Runtime with CloudFormation Lambda Hooks

This article discusses using AWS CloudFormation Lambda Hooks to enforce runtime compliance for Lambda functions before deployment. The solution provides a way to validate Lambda runtimes against a predefined list of permitted runtimes.

• CloudFormation Lambda Hooks intercept and evaluate resource configurations before provisioning
• A validation Lambda function checks if a Lambda function's runtime is compliant
• AWS Systems Manager Parameter Store stores the list of permitted runtimes
• The hook can be configured to fail deployment if a non-compliant runtime is detected
• The solution can be easily adapted to enforce policies on different AWS resources

The approach provides an automated mechanism to ensure only approved Lambda runtimes are used during infrastructure deployment, enhancing compliance and governance.
