Explore the concept of building better monoliths through implementing modulithic applications with Spring in this 51-minute conference talk from Spring I/O 2019 in Barcelona. Discover pragmatic alternatives to microservices architecture while addressing common issues in unstructured monoliths. Learn effective approaches to code organization, component structure, package design, transactions, and event-driven bounded context interaction. Gain insights into leveraging Spring Boot ecosystem features for testing individual bounded contexts and detecting architectural violations. Master techniques for implementing and preserving architectural concepts in modular, monolithic applications, preparing for potential future system splits. Dive into topics such as module mapping, annotations, package structure, module bootstrap, catalog integration, breaking dependency cycles, module dependencies, isolated testing, and Java modules.
