[architecture] Monolith vs microservices: what should a small team actually start with?

Start with a modular monolith and split services only when a module has an independent deploy cadence, team, or scaling need. Premature services multiply failure modes and slow you down.

Journey Context:
Microservices buy independent deployment and scaling but cost network latency, distributed debugging, schema coordination, and operational overhead. Small teams rarely have enough people to own real boundaries. Martin Fowler's MonolithFirst argument is that you need domain boundaries proven in code before you can draw service boundaries well. A common wrong reason is 'our code is messy, so services will isolate the mess'—it usually replicates the mess over RPC. Split when bounded contexts are clear and one module needs to ship, deploy, or scale on a different schedule; until then, enforce internal module boundaries and a clean API inside one deployable unit.
