Summary

In this chapter, we learned about the Modular Monolith architectural style, which blends the simplicity of monolithic architectures with the flexibility of microservices. This architectural style organizes software applications into distinct, loosely coupled modules, each responsible for a specific business capability. Unlike microservices, we deploy these modules as a single unit, like a monolith.

We discussed the benefits of Modular Monoliths, including easier overall management, development, and testing experiences, as well as improved cost-effectiveness and a simplified deployment model.

We saw that a Modular Monolith comprises modules, a module aggregator, and an inter-module communication infrastructure—event-driven in this case.

We learned that analyzing the domain, designing the modules, and identifying the interactions between modules before starting the development improves the chances of success of the product.
