[architecture] Small team: build a monolith or start with microservices?

Start with a modular monolith. Extract a service only when a boundary needs independent deployment cadence, scaling, or team ownership, not because the diagram looks cleaner.

Journey Context:
Microservices buy organizational autonomy at the cost of distributed tracing, contract tests, deployment pipelines, schema evolution, and operational runbooks. A small team pays that tax without getting the benefit. A monolith with enforced internal modules lets you refactor across boundaries cheaply and defer network split decisions until you have real data on load and team structure. The common trap is carving services too early, which turns every cross-cutting change into a multi-repository migration and a versioning negotiation.
