Aws Lambda Functions

This gets you up and running with AWS Lambda through multiple deployment paths: raw AWS CLI commands, Terraform, and SAM templates. The reference guides cover the full lifecycle from creating IAM roles to packaging functions, plus practical patterns like Lambda Layers for sharing code across functions. Good mix of Node.js examples and infrastructure as code approaches. The quick start shows the manual IAM setup you'll need, which is honestly the part most tutorials skip. Best practices lean heavily on the operational side: cold starts, concurrency limits, and not burning money on oversized memory allocations. If you're choosing between deployment methods or need working examples of event sources and permissions, this covers the common paths.
