Moving from A and B to ~150 microservices, the journey and learnings
summary
Recounts replacing two legacy monoliths (front end A and back-office B) with ~150 microservices over 4–5 years, built around REST/JSON APIs, stateless services with JWTs, and deployed via Docker and Kubernetes. About 10 back-end engineers iteratively extract business slices (order export, warehouse pick app, payment service) using feature flags and gradual rollouts; performance improves (example rewrite is ~70% faster) and the migration succeeds while noting added networking and distributed-systems complexity.
