Report #64639

[architecture] Should a startup use microservices or a monolith

Start with a modular monolith: single deployable unit with strictly enforced internal module boundaries \(package-private, no circular imports\). Extract to service only when a module needs independent scaling or team ownership.

Journey Context:
People cargo-cult 'Netflix microservices' and pay the distributed systems tax \(network latency, partial failures, deployment coordination\) with <10 engineers. The hard-won insight is that deployment coupling \(monolith\) is cheaper than operational coupling \(services\) for small teams. Enforcing module boundaries in code \(ports/adapters\) lets you split later without rewriting business logic.
