Hands-On Cloud-Native Applications with Java and Quarkus

By: Francesco Marchioni

Overview of this book

Quarkus is a new Kubernetes-native framework that allows Java developers to combine the power of containers, microservices, and cloud-native to build reliable applications. The book is a development guide that will teach you how to build Java-native applications using Quarkus and GraalVM. We start by learning about the basic concepts of a cloud-native application and its advantages over standard enterprise applications. Then we will quickly move on to application development, by installing the tooling required to build our first application on Quarkus. Next, we’ll learn how to create a container-native image of our application and execute it in a Platform-as-a-Service environment such as Minishift. Later, we will build a complete real-world application that will use REST and the Contexts and Dependency injection stack with a web frontend. We will also learn how to add database persistence to our application using PostgreSQL. We will learn how to work with various APIs available to?Quarkus?such as Camel, Eclipse MicroProfile, and Spring DI. Towards the end, we will learn advanced development techniques such as securing applications, application configuration, and working with non-blocking programming models using Vert.x. By the end of this book, you will be proficient with all the components of Quarkus and develop-blazing fast applications leveraging modern technology infrastructure.

Summary

In this chapter, we learned how to use CDI beans to produce, consume, and process messages using the Reactive Messaging specification. We also learned how to bootstrap and configure Apache Kafka and Active MQ's broker so that it acts as a distributed streaming platform for our CDI Beans. To put our new skills in place, we created an example stock trade application, which was initially run in development mode and then deployed as a native image on top of OpenShift.

Now, we have reached the end of this book, where we learned about the story of the gradual renewal of the Java Enterprise application, from monolith to native microservices running in the cloud. It was an exciting journey that certainly set a milestone, but this isn't the end of our hard work it's just the end of this story.
