Hands-On Enterprise Java Microservices with Eclipse MicroProfile

By: Cesar Saavedra, Heiko W. Rupp, Jeff Mesnil, Pavol Loffay, Antoine Sabot-Durand, Scott Stark

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.

Introducing Eclipse MicroProfile

Java EE has been an extremely successful platform. The Java Community Process (JCP) has been the steward of over 20 compatible implementations during its nearly 20-year history, resulting in a $4 billion industry. However, the management of Java EE by Oracle (unintentional or not) of Java EE (unintentional or not) stalled innovations, and while other standards have developed, the Java community worldwide and CIOs at all major enterprises desired an open standard for Java within their enterprise.

In its early stages, J2EE grew somewhat quickly from J2EE 1.2 up to J2EE 1.4, as the platform needed to address the immediate requirements of the enterprise. Beginning with Java EE 5 in May 2006, the pace began to slow down as the platform began to mature, and it was 3 years and 6 months between releases. After Java EE 7, which was released on June 12...
