Chapter 9. Event-Driven Architecture
In the last few chapters, we have looked at issues around stability and performance, and some patterns you can employ in your code, which enable more stable systems. In this chapter, we are going to take a more in-depth look at event-driven architecture.
As your system grows, these patterns become more important; they allow you to loosely couple your microservices, and therefore you are not bound to the same dependencies of intertwined objects common in monolithic applications. We are going to learn that with the right amount of up-front design and effort that loosely coupling your systems with events need not be a painful process.
