Reactive applications are flexible and robust. Reactive programming is already an established concept and there are many modern frameworks and tools which support it. You need to understand the concept in order to build truly reactive applications. But you do not need to switch from what you already know to build them. With standard Java EE you have wide range of options to add reactive behavior to new and even existing applications. I will show that Java EE is a modern and evolving framework, which supports reactive concepts. The latest versions of JDK and Java EE add even more asynchronous API to write fully reactive applications. On top of asynchronous processing in servlets, REST services and EJBs, there is asynchronous IO, managed multithreading and CompletableFuture with its promise-like API to tackle callback hell. Several Java EE implementations, like Payara Micro, go even further and provide extensions to scale your applications in natural way. Will include code examples and short demonstration using Payara Micro.
