Serverless beyond Functions
summary
Shows that Lambda scales across three AZs and can be free under the tier of 1 million invocations and 400k GB‑seconds, demonstrates the memory/CPU tradeoff (128MB runs a 1M-primes job ~12s for ~$0.025, 1GB finishes ~1.5s for the same cost), uses SAM and CloudFormation with sam‑local for packaging/testing and a graphical "serverless by design" exporter, implements event sourcing and canary deploys (example: 10% for 10 minutes), and builds a working AppSync GraphQL frontend backed by DynamoDB with real‑time subscriptions.
