[architecture] Premature microservices extraction slowing down small teams

Start with a modular monolith \(single deployable unit with internal modules/bounded contexts\) until the team size \(>8-10 developers\) or deployment cadence conflicts force a split; extraction before boundaries are clear results in distributed monolith hell.

Journey Context:
Small teams often split into microservices early for 'clean architecture,' but end up with distributed monoliths \(tight coupling via sync calls, shared databases\) that are harder to refactor than a single codebase. Martin Fowler's 'Monolith First' strategy argues that boundaries are unknown early in a project; a modular monolith allows refactoring within a single process until clear bounded contexts emerge. The 'Microservice Premium' \(higher baseline cost for distributed systems\) only pays off when team scale requires independent deployment velocity. Indicators for splitting: teams stepping on each other's deployments, conflicting scaling requirements, or different data persistence needs \(polyglot persistence\).
