Summary

In this chapter, we have seen a very quick overview of the JEE specification and some very interesting alternatives, such as MicroProfile and Quarkus, which are certified MicroProfile implementations.

We have learned about the JEE standard and why it's so popular. We also learned about the basic usage of the WildFly application server, along with some widely used JEE APIs, including RESTful Web Services, JMS messaging, and JPA persistence. We also learned about the MicroProfile standard, a modern alternative to JEE, and the Quarkus framework, which implements the MicroProfile standard. We also learned about some Quarkus extensions, including RESTful Web Services, JMS messaging, and persistence with Panache.

We will see more Quarkus cloud-native features in Chapter 9, Designing Cloud-Native Architectures.

In the next chapter, instead, we will continue our discussion on the concept of middleware by having a look at the world of application integration.
