[architecture] Should I start with microservices for my startup?

Start with a modular monolith. Organize code into well‑defined modules with clear interfaces \(e.g., bounded contexts\) but deploy as a single unit. Only extract services when you have clear reasons: independent scaling, team boundaries, or external integration needs. This reduces complexity, deployment friction, and operational overhead. Microservices add network latency, distributed debugging, and deployment coordination that most early‑stage teams don’t need.

Journey Context:
A common mistake is assuming microservices are needed for scalability from day one, resulting in a distributed monolith — a system with all the drawbacks of microservices \(network calls, eventual consistency\) and none of the benefits \(independent deployability\). The modular monolith allows you to refactor toward services later without premature complexity. Martin Fowler and ThoughtWorks advocate this approach. Tradeoffs: a modular monolith may require more discipline to prevent coupling, but it’s much easier to manage for a small team.
