[architecture] Premature microservices adoption with small engineering teams \(<10 developers\)

Build a modular monolith with strict internal boundaries \(Hexagonal/Ports-Adapters architecture\); extract services only when team size forces deployment velocity conflicts or components require orthogonal scaling.

Journey Context:
Teams under 10 people often split into microservices for 'clean architecture' but face 'distributed monolith' pain—debugging across services, integration testing hell, and deployment coordination—without the team size to justify the overhead. The proven pattern is 'Monolith First': enforce modular architecture inside a single deployable unit using strict boundaries \(anti-corruption layers\). This allows rapid refactoring and testing. Services should be extracted only when \(1\) different teams need independent deployment cadences \(Conway's Law\) or \(2\) components have fundamentally different scaling requirements \(e.g., CPU vs. GPU vs. Memory\).
