Quarkus Cookbook

Preface

We’re excited to have you with us on this journey of learning and using Quarkus! Unlike traditional Java frameworks, which can be big, cumbersome, heavy-weight, and take months to learn, Quarkus builds on knowledge you already have! It uses JPA, JAX-RS, Eclipse Vert.x, Eclipse MicroProfile, and CDI, just to name a few technologies you’re already familiar with. Quarkus then takes your knowledge and combines it into a compact, easy-to-deploy, fully Kubernetes-optimized container targeting either OpenJDK Hotspot or GraalVM. This allows you to pack your Kubernetes cluster as tightly as possible, making use of every resource on the machine as your application scales to meet demand. Regardless of where you are on your migration to Kubernetes, you’ll find something useful with Quarkus, and this book will give you the tools and resources you need to succeed.

Who Should Read This Book

Obviously, we want everyone to read this book! However, we have made some assumptions about the reader:

• You are already familiar with Java and application development within that space.

• You understand traditional software development practices.

• You regularly deploy services into a cluster of machines or into the cloud.

Why We Wrote This Book

Quarkus is a relatively new framework in a new space (native Java and GraalVM). We wanted to dive into some more examples and how-to sections than what you will find on the internet. Also, we wanted to give you as much substance with this book as possible. ...
