Event-Driven Spring for the Win!

At its core, Spring is built on a dependency injection framework that enables (among other things) loose coupling of application components. But dependency injection is not the only way to achieve loose-coupling. Event-driven design, as its name implies, enables components to react to events, not knowing where they came from, process those events, and then publish new events not knowing who (if anybody) will be handling those events.

In this session, you'll learn how to apply events in Spring applications to achieve looser coupling of components. We’ll start by looking at some fundamental abilities that the core framework offers for handling events. Then we'll quickly move into a higher-level form of event-driven architecture where events aren’t just handled within a single deployment, but span across multiple microservices by employing Spring Cloud Stream and Spring Cloud DataFlow. And then we’ll see how, when paired with serverless functions based on Spring Cloud Function, we can achieve not only loose-coupling of microservices, but also an efficient yet scalable use of resources in our event-driven architecture.
