Getting Started: Modular Monoliths in .NET
Learn how to structure your .NET applications with modular monoliths. This course covers designing modular systems that improve maintainability without the complexity of microservices.
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, you�ll learn how to get started building a
modular monolith application using a real world sample, the RiverBooks ecommerce site.
