[architecture] When should a startup or small team split into microservices?

Build a monolith first; extract a service only after the boundary is stable and you need independent deployment, scaling, or team autonomy.

Journey Context:
Microservices are not a scaling shortcut for a small team — they are an organizational scaling technique. Premature splitting multiplies failure modes, forces you to design network contracts before you understand them, and turns method calls into distributed transactions. A modular monolith lets you refactor inside one deploy unit until the seams are obvious. The right time to extract is when a module changes independently, is owned by a different team, or needs its own failure domain. Until then, the operational cost is pure drag.
