Objectives

  • You can classify the idea behind moduliths and how they differ from microservices.
  • You will define and structure modules with Spring Modulith.
  • Implement suitable communication patterns between modules (synchronous, asynchronous, events).
  • You can automatically check architecture rules and integrate them into CI/CD pipelines.
  • You can independently design and extend a modular sample application.

Audience

  • Software developers who work with Spring Boot and want to structure their applications in a clearly modular way.
  • Software architects who want to critically examine microservices or design hybrid architectures.
  • Teams that want to modernize existing monoliths and gradually convert them into modular systems.

Description

Get a practical overview of Spring Modulith. This is a modern approach to structuring applications in a modular way without having to deal with the complexity of distributed architecture approaches.

‍

Microservices are often considered the ideal solution for modularization – but they come with significant technical and organizational challenges. Moduliths offer a pragmatic alternative: a modular monolith that clearly structures technical aspects and remains maintainable in the long term.

‍

We apply the concepts in practice using an example application. We discuss how dependencies can be controlled, architecture rules can be checked automatically, documentation can be generated, and existing systems can be modernized step by step.
