The architecture and design of an application significantly influences its maintainability, testability, and quality in general. Spring has always been a versatile tool that supports architects implementing the practices and patterns that have emerged to align technical building blocks in their code bases with domain concepts and boundaries. It lets developers build applications that clearly reflect architectural ideas and that are ultimately more amendable and maintainable. Key aspects of that are code organization for encapsulation, the Spring bean relationship arrangement, and how to use domain events to decouple logically individual parts of the application even within a singular artifact.

The talk discusses those patterns and approaches to introduce Spring Modulith to, in turn, show how they uniquely position Spring developers to build better structured, more maintainable applications.
