Deep Dive: Modular Monoliths in .NET
Take your Modular Monoliths journey to the next level
About This Course
A monolith refers to a software application that is deployed as a single
physical deployment. Many monolithic applications lack sufficient structure
and end up becoming Big Balls of Mud. By contrast, a modular monolith breaks
up the application into logical modules which are largely independent from one
another. This provides many of the benefits of more distributed approaches like
microservices without the overhead of deploying and managing a distributed
application. In this course, we will build on top of your existing knowledge of Modular Monoliths
that you gained during the Getting Started course of the series and you�ll learn
how to apply advanced Modular Monolith patterns and add more features to the RiverBooks ecommerce site.
