A regular monolith can still be well-organized. But a modular monolith goes a step further by enforcing strict boundaries between parts of the system. In this video, I compare the same application implemented as a traditional monolith and as a modular monolith. You’ll see how coupling slowly creeps into a codebase, why folder structure alone is not enough, and how module boundaries help you keep your architecture flexible as the system grows. You’ll learn: - What makes a module different from a folder - Why monoliths often become tightly coupled over time - How modular monoliths enforce boundaries - Why public APIs between modules matter - How database/schema isolation fits into the design - When extracting a module into a separate service becomes easier A modular monolith is still deployed as one application. But the key difference is that each module has clear ownership, a public contract, and fewer hidden dependencies. This gives you many of the design benefits of microservices without taking on distributed systems complexity too early.
