Evolving to Cloud Native
summary
Practical playbook for moving a legacy portfolio to cloud: assess each app for tech stack, startup time, filesystem and vendor dependencies, and 12‑factor gaps, cataloging results (assess portfolio (~400 apps, 3–4 hr/app)). Run pilots, refactor incrementally—most apps need weeks not months to modernize (refactor measured in weeks per app)—or choose lift‑and‑shift, containers, a platform like Cloud Foundry/Kubernetes, or serverless where latency and billing fit. Real outcomes: improved dev→prod parity, faster deploy cadence (example cited: 3,000 deploys/month (Scotiabank)), but watch cold starts and runaway costs.
