Taming a beast
summary
Bol.com moves a 70‑engineer monolith from four‑week releases to continuous delivery by rebuilding a 200+ stable integration test suite (run time cut from >1 hour to ~20 minutes), containerizing the app, and automating with Mayfly and Jenkins plus a small “git diff” service that tracks versions. Result: 30 releases in eight weeks, 447 features, average lead time ~4 days, ability to roll back fast; a simple feature toggle service is next.
