Modular Monolith

ELI5 — The Vibe Check

Modular Monolith is the best of both worlds: one deployable app (monolith) but organized into clear, separate modules that could become microservices someday. It's the responsible middle ground. You don't suffer microservice complexity now, but you're ready to split later if needed.

Real Talk

A Modular Monolith is a single deployable application organized into clearly bounded modules with explicit interfaces between them. Each module owns its data and logic. Provides the operational simplicity of a monolith with the organizational clarity of microservices. Often a stepping stone to microservices.

When You'll Hear This

"Start with a modular monolith and extract services only when you need to scale." / "Our modular monolith has clear boundaries — each module is almost a microservice already."
