Report #74669

[architecture] Building microservices from day one for unproven products or small teams \(<10 developers\)

Start with a modular monolith \(strict internal module boundaries, single deploy unit\); extract services only after boundaries are well-understood and team size demands independent deploy velocity

Journey Context:
Microservices impose a heavy tax: distributed debugging, eventual consistency headaches, DevOps complexity, and performance overhead from network calls. Teams often create 'distributed monoliths' with tight coupling across HTTP calls that would be simple method calls in a monolith. A modular monolith allows rapid refactoring and type-safe transactional boundaries while keeping operational simplicity. Extract to services only when subteams need to deploy on different schedules.
