Reactive systems and event-driven architecture are becoming essential to application design–and companies are taking note. Reactive systems ensure applications are responsive, resilient, and elastic no matter what failures, latency, or other errors may be occurring, while event-driven architecture offers a flexible and composable option for distributed systems. This practical resource helps you bring these approaches together using Quarkus, a Java framework that greatly simplifies the work developers must undertake for cloud deployments. This book covers how Quarkus 2.0 reactive features allow the smooth development of reactive systems.

Reactive is an overloaded word. If you are reading this book, you probably searched for “reactive” with a search engine to understand what it’s all about. If you didn’t, no worries, you save yourself from a lot of confusion. There are many reactive things: reactive systems, reactive programming, reactive extensions, reactive messaging. Every day new ones pop up. Are all these “reactives” the same “reactive”?

Are they different?
These are the questions we are going to answer in this chapter. We are going to sneak a peek at the reactive landscape to identify and understand these different nuances of “reactive,” what they mean, the concepts associated with them, and how do they relate to each other. Because yes, without spoiling too much, all these “reactives” are related.
