Quarkus in Practice

Quarkus in Practice: Building Modern Java Applications with Speed and Simplicity is a practical guide for developers, architects, and DevOps professionals who want to build cloud-native Java applications with confidence. It introduces Quarkus as a modern framework designed for fast startup times, low memory consumption, and an excellent developer experience, while showing how it combines imperative and reactive programming models to fit a wide range of application needs. From the fundamentals of project setup to the core ideas behind Quarkus's design, the book helps readers understand why it has become a compelling choice for enterprise Java development.

The book then moves into hands-on implementation, covering the essential skills needed to develop production-ready applications. Readers will learn how to create and configure projects with Maven or Gradle, build RESTful and event-driven services, work with persistence and messaging, and apply security, testing, and observability best practices. Each topic is presented with practical examples and clear guidance, making it easier to move from concept to working application while maintaining performance, reliability, and maintainability.

Beyond the basics, Quarkus in Practice explores the operational side of modern Java delivery, including containerization, Kubernetes deployment, CI/CD pipelines, and native image optimization. It also introduces advanced topics such as creating custom extensions and working with the Quarkus ecosystem to extend functionality as applications grow. Whether you are modernizing existing services or starting a new cloud-native project, this book provides a focused, accessible path to building fast, simple, and scalable Java applications.
