Frequently Asked Questions

(01)Didn't Netflix prove microservices are best?
Netflix has thousands of engineers and billions of users. Their problems aren't your problems. They also started as a monolith. Most companies never reach the scale where microservices benefits outweigh complexity.
(02)How do I know when to switch?
Consider microservices when: team size exceeds 50 developers, deployment conflicts are frequent, different components need different scaling, or you have clear bounded contexts. Not before.
(03)What about modular monoliths?
Modular monoliths offer the best of both: clean architecture, domain separation, but single deployment. This is often the right middle ground before microservices.
