Hands-On Cloud-Native Applications with Java and Quarkus

By: 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 took a comprehensive overview of the MicroProfile specification and how to integrate it with Quarkus applications.

We started with an overview of the MicroProfile API and how it fits into the overall picture of cloud-based microservices. Then, we covered the major MicroProfile specifications.

First, we looked at the Health API and how it can report the liveness and readiness of your services. Then, we covered the Fault Tolerance API, which can be used to design resilient services. Next, we discussed the application's telemetry data and how it can be collected using the Metrics API. Another key aspect we covered was documenting of services and tracing the flow of requests, which can be carried out using the OpenAPI and tracing specifications. Finally, we learned how to create REST clients to simplify our interaction with remote services.
