How to reuse patterns when developing infrastructure as code
summary
Shows how CloudFormation modules package opinionated templates, get published and versioned, and how changing the default module version pushes updates to consumers (demo moves a module from v11 to v12). Demonstrates CDK constructs and that cdk synth turns a few lines of code into hundreds of CloudFormation lines (example: ~600–700 lines; an ALB Fargate pattern can synthesize ~829 lines). Builds a Lambda + API Gateway with CDK and deploys it; the deployed API returns the expected welcome response.
