[architecture] Microservices or monolith for a small team building a new product?

Start with a modular monolith. Extract a service only when a module has independent deploy cadence, scaling needs, or team-ownership boundaries. A small team should optimize for fast refactorability and end-to-end tests, not network boundaries.

Journey Context:
Microservices are not a scaling shortcut for headcount; they are an organizational scaling technique. For a small team, every service boundary adds deployment, observability, schema versioning, network failure modes, and distributed transactions. The result is usually a 'distributed monolith' with the worst of both worlds. A well-modularized monolith lets you enforce clean internal boundaries \(ports/adapters, feature modules\) while keeping refactoring, testing, and debugging trivial. The right time to split is when one module needs to ship on a different schedule, scale differently, or be owned by a different team—not because the diagram looks cleaner. If you cannot draw the bounded context clearly, you are not ready to extract it.
