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.

  1. At the time of writing, there are eight implementations of Eclipse MicroProfile, all of which are open source. They are Thorntail, Open Liberty, Apache TomEE, Payara Micro, Hammock, KumuluzEE, Launcher, and Helidon. There is also Quarkus as the latest entrant.
  2. An application server is a container for Java EE applications. An application assembler only includes the functionality that the application needs, instead of requiring an application server to be up and running, and commonly generates an executable JAR. An application assembler can generate an uberjar, a self-contained runnable JAR file, or an application jar with its runtime dependencies located in a sub-directory, for example, an accompanying lib or libs sub-directory.
  3. Here is a short description of the current eight MicroProfile implementations on the market:
