This comprehensive guide demystifies Java cloud-native application development, leveraging standard Microprofile APIs while delving into Payara-specific features like automatic clustering and enhanced application initialization performance. By utilizing class data sharing, developers can optimize startup performance, while configuring cloud-native applications using industry-standard tools like Maven and Gradle. The book also sheds light on developing essential cloud-native functionalities, such as health checks and request tracing, through MicroProfile APIs.

The journey begins with the fundamentals of developing microservices using RESTful web services, seamlessly transitioning to creating microservice clients utilizing MicroProfile and the REST client API. Dependency Injection via Jakarta Context and Dependency Injection (CDI) is explored in depth, along with various approaches to application configuration, including property files, environment variables, and system properties. Developers will gain expertise in configuring fault tolerance and high availability, generating system and custom application metrics, and implementing health checks to automatically enhance application health.

OpenTracing enables developers to trace request flow across service boundaries, facilitating future maintenance with automated documentation generation. Additionally, the book covers securing cloud applications and automating application clustering for improved startup performance.

By mastering the techniques outlined in this book, developers will be well-equipped to build robust, scalable, and cloud-native applications using Payara Micro.
