Microservices Course

Welcome to Microservices: From Monolith to Production-Grade Distributed Systems — a mentor-led course for engineers who need to decompose systems, ship independently, and surviv…

Microservices are independently deployable services aligned to business capabilities — each owns its data, communicates over well-defined APIs or events, and can scale and fail…

Monolith vs microservices is not a purity contest — it's a trade-off between development simplicity and organizational scale.

When to split a monolith: clear bounded contexts, independent scaling needs, team ownership pain, or deploy blast radius — not because microservices are fashionable.
