Quarkus for Enterprise Java Developers: Modernize Legacy Spring Boot and Jakarta EE Apps, Reduce Cloud Costs, and Build High-Performance Microservices (Paperback) (ISBN-13: 9798176767797)

Is your enterprise Java application carrying the cost of yesterday's architecture?

Java remains a powerful foundation for enterprise software-but modern cloud environments demand faster startup times, smaller memory footprints, efficient scaling, and production-ready microservices. Quarkus for Enterprise Java Developers shows experienced Java developers how to modernize enterprise applications and build lightweight, high-performance services with Quarkus.

At its core, this book provides a practical path from traditional enterprise Java development to cloud-native Quarkus applications. Instead of focusing on lengthy theory, it concentrates on production-oriented techniques you can apply to real systems, whether you are starting a new service or modernizing an existing Spring Boot or Jakarta EE application.

Inside, you will learn how to:

• Build high-performance REST APIs using Jakarta REST and Quarkus REST.

• Use Hibernate ORM with Panache for practical enterprise data persistence.

• Work with reactive programming and virtual threads for modern concurrency.

• Refactor and migrate existing Spring Boot applications to Quarkus.

• Modernize legacy Jakarta EE and JBoss applications without unnecessarily rewriting business logic.

• Secure enterprise APIs with modern authentication and authorization approaches.

• Add resiliency, observability, metrics, and distributed tracing to production services.

• Build event-driven microservices with enterprise messaging technologies.

• Compile applications into GraalVM native executables and deploy them efficiently to Kubernetes.

• Apply Quarkus to emerging enterprise AI workflows with LangChain4j.

You will also work with practical Quarkus development features such as Live Coding, Dev Services, Continuous Testing, Maven, Gradle, and the Quarkus Dev UI-helping you create a faster development and testing workflow.

Whether you are modernizing an existing Java estate, developing cloud-native microservices, or preparing enterprise applications for Kubernetes, this book gives you practical techniques for building leaner and more responsive Java services.
