Detailed Summary of the Book

The book begins with an introduction to the concept of cloud-native applications and why they matter in today's world of distributed systems and microservices. It progresses into exploring Quarkus—a Kubernetes-native Java framework designed to transform how developers build applications for the cloud. Through practical examples and hands-on guidance, you’ll learn how to develop high-performance applications that are perfectly suited for containerized environments.

The authors thoughtfully cover the full development lifecycle, from setting up a development environment to deploying applications on cloud platforms using orchestration tools like Kubernetes. You'll explore essential topics like reactive programming, dependency injection, and serverless computing, while also diving into advanced concepts such as distributed transactions and observability.

• Understanding the principles of cloud-native application design
• Hands-on tutorials for creating Quarkus-based microservices
• Techniques for optimizing performance and achieving ultra-low startup times
• Best practices for deploying applications to Kubernetes and working with serverless architecture
• Debugging, testing, and scaling applications in cloud-native environments

By the end of the book, readers will have the practical expertise to design, code, and deploy robust Java applications that harness the full power of Quarkus and the cloud-native ecosystem.
