Report #76645

[architecture] Prematurely adopting microservices as a small team \(<10 engineers\)

Start with a modular monolith \(strict internal modules/packages mapping to bounded contexts\) and extract services only when deployment velocity or scaling constraints force it.

Journey Context:
Microservices impose a heavy 'distributed systems tax': network latency, schema evolution, distributed tracing, and integration testing complexity. Small teams burn cycles on DevOps instead of product. A modular monolith preserves refactoring agility \(single deploy, in-process calls\) while keeping code boundaries clean for future extraction. The trap is confusing 'clean architecture' with physical separation; logical modularity scales further than premature network boundaries.
