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.

Quarkus – a Kubernetes-native Java framework

One of the main challenges of a microservices architecture is that the proliferation of services can increase the complexity of your systems unless you have a valid framework to orchestrate them from. Also, without a centralized function for authentication, data management, and an API gateway, the advantages of a microservices architecture are invalidated by these challenges.

In this sense, the arrival of Kubernetes is a real revolution in IT patterns. With the help of Kubernetes-based orchestration, you can enhance efficiency and resource utilization by managing and scheduling your microservices in a dynamic manner. This also adds an advanced resiliency level. You can continue to operate as demand varies, without worrying about container failure. To close the circle and unify all the components, we need a framework that has...
