Report #82529

[architecture] Microservices or monolith for a small engineering team of 5-10 people?

Build a Modular Monolith with compiler-enforced package boundaries \(internal modules/packages\) that isolate bounded contexts; deploy as a single unit but structure code so entire domains can be extracted into services later if team size justifies it.

Journey Context:
Small teams adopt microservices for 'scalability' but drown in network latency, distributed debugging, and deployment orchestration that kills velocity. A 'big ball of mud' monolith is also bad because domains become tangled. The Modular Monolith \(a la Sam Newman\) enforces strict internal boundaries—use Java modules, C\# internal classes, or Go package visibility so domains don't leak into each other. You get the development speed of single-process debugging and atomic transactions, but the architecture can evolve to distributed when the team grows to 30\+ and network boundaries become necessary, not just fashionable.
