Definition
A Modular Monolith is a software architecture where code is deployed as a single unit but organized into strictly isolated modules with defined boundaries.
Why It Matters
Microservices are complex and expensive to manage (DevOps nightmare). Monoliths get messy (Spaghetti code). Modular Monoliths give you the simplicity of deployment with the organization of microservices.
How It Works
- 1
Code is in one repo.
- 2
Modules (e.g., `Billing`, `Users`, `Inventory`) cannot import each other's internal code.
- 3
Communication happens via public interfaces.
- 4
Modules can be peeled off into microservices later if needed.
The NetForce Take
Start here. Don't build microservices until you have 50+ engineers. A well-structured monolith can handle millions of users.
