The Modern Monolith, with Spring Modulith by Cora Iberkleid @ Spring I/O 2024

Spring I/O 2024 - 30-31 May, Barcelona

In the last decade, much emphasis has been placed on decomposing monoliths into microservices. While this practice has important benefits, including increased agility for development teams and independent lifecycle management for applications, it also introduces new complexities, such as managing many git repositories and many component deployments.

In some cases, the benefits of monolith decomposition are absolutely necessary, but not in all. Sometimes we invite complexity for no good reason. In these cases, it behooves us to consider maintaining monolithic code bases. This does not mean, however, to revert back to the spaghetti monoliths of yesteryear, or to the cursory attempt to organize code into services of the SOA age. Instead, we must be sure to apply the hard-fought lessons from microservices and create a new paradigm for Modern Monoliths.

Enter Spring Modulith. In this talk, we will explore the concept of the modern modular monolith and how this compares to the monoliths of yore. How are they different, and what challenges do these differences aim to resolve?

By the end of this talk you will understand when and how to apply the principles of modular architecture to your Spring Boot applications using Spring Modulith.
