[architecture] Startup team debating microservices vs monolith architecture

Build a Modular Monolith with strict internal boundaries \(ports/adapters architecture\); extract services only when deployment scaling needs diverge

Journey Context:
Teams conflate 'clean code' with 'distributed services.' Microservices introduce network latency, distributed tracing complexity, and deployment orchestration overhead that destroys productivity for teams under 10 engineers. The Modular Monolith enforces domain boundaries via compiler-enforced modules \(e.g., Java packages, Go internal/ directories, Python namespace packages\) while keeping operational simplicity. Services should be extracted only when subsystems require independent deployment cadences or scaling characteristics that justify the operational cost of RPCs.
