This Old App, a guide to renovating apps for the cloud
summary
Migrating a legacy app to the cloud requires concrete choices not platitudes: compare lift-and-shift (fast but brittle, risks lost session state and hidden dependencies) versus full refactor into microservices (high effort, lower long‑term risk) and the practical strangler pattern for incremental decomposition. Use an API gateway to expose on‑prem services, avoid backhauling traffic, and consider containerize with Docker to enforce isolation and limit blast radius. Start with a small but meaningful pilot, expect to learn what breaks, and harden CI/CD and access roles to prevent cloud account takeover.
