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 got an overview of the current landscape of the IT industry. As we have learned, Kubernetes adds a completely new dimension to traditional language-based building blocks by offering a new set of distributed services and a runtime environment for creating distributed systems that spread across multiple nodes. Although the core principles of creating containerized applications don't strictly require that you decompose your monolithic applications in single services, there are evident advantages in doing so in terms of isolation, scalability, team independence, monitoring, resilience, and life cycle automation.

Later, we discussed the actual applications that can run natively by introducing Quarkus, an amazing framework where we can create serverless, native applications without losing the skills we learned as Java developers.

Now that we've...
