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.

Quarkus

The open source Quarkus project made its debut in 2019. Quarkus is a Kubernetes-native Java stack with that can compile to native machine language or building to HotSpot (OpenJDK). When using Quarkus, your application consumes very little memory, has great performance that allows it to handle a high throughput of invocations, and has a very fast start up time (that is, boot plus first response time), making Quarkus a great runtime for containers, as well as cloud-native and serverless deployments. Quarkus also provides an extension framework that allows the quarking of libraries and projects to make them work seamlessly with Quarkus.

Quarkus's mission is to transform your full application and the libraries it uses into an optimal output for GraalVM. To do this, you need to analyze and understand the full closed world of the application. Without the full and complete...
