From Flying Circus to Holy Grail: Migrating the Twilio API from PHP to Python
summary
Company extracts features from a 500k‑line PHP monolith into small services and builds starship, a Python/Flask federation that maps public REST endpoints to internal REST services using the proxy resource pattern. Starship uses requests and gevent, centralises auth/validation/rate‑limit, and handles 5,000 RPS and five billion monthly requests while the team runs 1,200 unit tests (3s), 30s integration tests and 5min cluster tests. Deploys use shadowing, canaries and percentage rollouts; migration succeeds with zero downtime.
