Going Serverless

" summary

Uses the Serverless Framework to deploy code to AWS Lambda and Api Gateway, with CloudFormation for infra and DynamoDB/RDS as examples. Demo builds a left-pad HTTP endpoint, ships via sls deploy, tests functions with mocha/chai, and runs Ruby by shim‑ning in mruby. Measured timings: API baseline ~30–40 ms, end-to-end ~70–75 ms, mruby ~5–6 ms slower, and cold starts spike to ~650–700 ms. The demos work as proof of concept.
