Microservices: the right tool for the right problem

Microservices architecture splits a system into small independent services, each with its own team, database and delivery cycle. At companies with dozens of developers it solves a real organizational problem: teams ship independently without waiting on each other, and a failure in one component does not bring down the whole. Our position, formed by experience and against the marketing current: for most companies, prematurely adopted microservices are an expensive mistake. Distributed complexity — network between services, data consistency, debugging across systems — is paid permanently, while the benefits appear only at a certain team scale. Our standard recommendation is the modular monolith: one system, internally structured into strictly bounded modules, which ships fast today and can be split into services tomorrow when — and if — scale demands it. We design both; what matters is the correct diagnosis first.
