Hands-On Enterprise Java Microservices with Eclipse MicroProfile

Overview of this book

Eclipse MicroProfile has gained momentum in the industry as a multi-vendor, interoperable, community-driven specification. It is a major disruptor that allows organizations with large investments in enterprise Java to move to microservices without spending a lot on retraining their workforce. This book is based on MicroProfile 2.2, however, it will guide you in running your applications in MicroProfile 3.0. You'll start by understanding why microservices are important in the digital economy and how MicroProfile addresses the need for enterprise Java microservices. You'll learn about the subprojects that make up a MicroProfile, its value proposition to organizations and developers, and its processes and governance. As you advance, the book takes you through the capabilities and code examples of MicroProfile’s subprojects - Config, Fault Tolerance, Health Check, JWT Propagation, Metrics, and OpenTracing. Finally, you’ll be guided in developing a conference application using Eclipse MicroProfile, and explore possible scenarios of what’s next in MicroProfile with Jakarta EE. By the end of this book, you'll have gained a clear understanding of Eclipse MicroProfile and its role in enterprise Java microservices.

Developing and running MicroProfile applications across clouds

What features does MicroProfile provide to support development across clouds? Microservices and support for language-agnostic communication based on HTTP REST API are two of the main features that are supported. In addition, MicroProfile Config supports the integration of cloud environment variables that define integration with the cloud environment. MicroProfile Health Check supports integration with the cloud environment health checks. MicroProfile Metrics and MicroProfile OpenTracing support integration with the DevOps monitoring tasks. Finally, MicroProfile fault tolerance supports fallback and recovery behaviors between the independent microservices.

Eclipse MicroProfile provides capabilities that allow for the development of microservices and applications across clouds. But what about the underlying cloud compute...
