Microservices vs Monoliths A Developer's Perspective

You don't need microservices. You need boundaries.

The industry loves buzzwords. Microservices were all the rage for a while — but in practice, most teams I've worked with needed something simpler: a well-structured monolith.

Microservices introduce complexity: network latency, deployment overhead, inter-service contracts. These aren't bad — if you need them.

But most apps start simpler. And they should.

A modular monolith with clear separation of concerns, proper versioning, and layered design can scale surprisingly far.

Complexity isn't a badge of honor — it's a tradeoff.

Choose wisely.
