The industry spent a decade splitting monoliths apart and the last few years quietly putting some back together. The lesson: architecture should follow the problem, not the hype.

When each one wins

A modular monolith is faster to build, easier to test, and simpler to operate — ideal for most teams and most stages. Microservices earn their keep when independent teams need to deploy independently, when parts of the system scale very differently, or when fault isolation is critical.

Our default is a clean monolith with clear internal boundaries. If a boundary later needs its own deploy cadence or scaling profile, then we extract it — with evidence, not on faith.
