Proactively validate your AWS CloudFormation templates with AWS Lambda

This article discusses using AWS CloudFormation Hooks, specifically Lambda Hooks, to proactively validate infrastructure-as-code templates before deployment. The example focuses on validating S3 bucket versioning configuration.

• Lambda Hooks allow custom validation logic to be integrated into CloudFormation stack operations
• Users can create Lambda functions to check resource configurations before provisioning
• The sample code demonstrates validating S3 bucket versioning during create and update operations
• Hooks can be activated through AWS Console, CLI, or CloudFormation
• The approach enables enforcing infrastructure policies at the point of deployment

The solution provides a flexible way to implement custom validation and governance checks for AWS infrastructure deployments, reducing compliance risks and improving infrastructure management.
