Keep Cloud Infrastructure Flexible with Ports & Adapters
summary
Claims that cloud choices usually come from personal taste not data and recommends a set‑based engineering approach that keeps options open. Describes Hexagonal Architecture / Ports and Adapters that isolate core logic so adapters for Lambda + API Gateway, AppSync, Aurora Serverless, Postgres, MongoDB or Cassandra can be swapped. Uses a parking‑ticket use case (buy ticket, inspector check) as the concrete example and shows migrating from serverless Lambda to Kubernetes when cost or latency forces a change.
