Report #57643

[architecture] Should a startup or small team \(<10 devs\) build microservices or a monolith

Start with a modular monolith \(strictly separated bounded contexts within a single deployable\) until team size exceeds ~8 engineers or specific services require independent scaling/deployment velocity; extract services only when domain boundaries are stable and the operational tax \(observability, CI/CD duplication\) is justified by scaling constraints

Journey Context:
Premature microservices impose 'micromanagement overhead': distributed tracing complexity, integration test nightmares, deployment coordination, and resistance to cross-cutting refactors. Small teams have high bandwidth communication \(Conway's Law\), making monolithic collaboration efficient. A 'modular monolith' enforces clean architecture boundaries \(ports/adapters\) so that extraction later is mechanical, not surgical. The threshold for extraction is usually when one component needs to scale on a different axis \(CPU vs Memory\) or when teams need to deploy at different cadences.
