Models, Modules, Microservices – Better Domain Models with Java 9 Modules
summary
The talk explains how to use Java 9’s module system (Project Jigsaw / Java Platform Module System) to express Domain-Driven Design’s Bounded Contexts directly in source code. It shows how modeling domains as smaller, well-cut modules produces clearer, less error-prone models that multiple teams can develop in parallel, and how this modular approach can serve as a precursor to or replacement for microservices.
