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.

Introduction to MicroProfile OpenAPI and its capabilities

The mobile force that fuels the digital economy led to the need for businesses to establish an omni-channel approach to development in order to optimize costs, increase efficiencies, and improve customer experience. A facilitator of this approach was APIs, which led to the API economy and concepts such as API-led or API-first development practices. In addition, the microservices architecture has become the architecture of choice for modern development. API-based (that is, RESTful) communication among microservices has been adopted as the de facto standard because it is a good fit for the smart endpoints and dumb pipes, decentralized governance, and decentralized data management characteristics of microservices.

However, as the number of microservices increases in a microservices architecture, their management can become...
