Report #78770

[architecture] Monolith or microservices for a startup with fewer than 10 engineers?

Start with a modular monolith: deploy as a single unit but enforce strict internal module boundaries \(no cross-module DB queries\). Extract to services only when a module needs independent deploy velocity or scaling beyond the monolith's capacity.

Journey Context:
Small teams adopt microservices for 'clean architecture' but pay massive coordination tax: integration testing becomes distributed systems debugging, deploys require choreography, and local development breaks. The 'death star' diagram evolves. Modular monoliths give you the codebase organization benefits \(bounded contexts\) without the network partition failures. Extract when a team owns a module and deploys >3x daily or needs tech divergence \(e.g., GPU workers\). Premature extraction kills velocity.
