Hands-On Cloud-Native Microservices with Jakarta EE

By: Luigi Fugaro, Mauro Vocale

Overview of this book

Businesses today are evolving rapidly, and developers now face the challenge of building applications that are resilient, flexible, and native to the cloud. To achieve this, you'll need to be aware of the environment, tools, and resources that you're coding against. The book will begin by introducing you to cloud-native architecture and simplifying the major concepts. You'll learn to build microservices in Jakarta EE using MicroProfile with Thorntail and Narayana LRA. You'll then delve into cloud-native application x-rays, understanding the MicroProfile specification and the implementation/testing of microservices. As you progress further, you'll focus on continuous integration and continuous delivery, in addition to learning how to dockerize your services. You'll also cover concepts and techniques relating to security, monitoring, and troubleshooting problems that might occur with applications after you've written them. By the end of this book, you will be equipped with the skills you need to build highly resilient applications using cloud-native microservice architecture.

MicroProfile LRA

The MicroProfile specification aims to propose a standard solution about the management of the transactions in distributed systems as microservices, based on the saga pattern.

The specification is Long Running Actions (LRA) for MicroProfile: it's built by the Narayana team under the Eclipse MicroProfile initiative. Currently, it is in a "in progress" state, and it is one of the main topics under discussion in the community.

It proposes a new API for the coordination of long-running activities: the approach would be totally different from the one implemented, for example, in the Extended Architecture. The target is to guarantee a globally consistent outcome without the need to set locks on data that limits the scalability of the system.

The Narayana LRA implementation is based on the standard specifications provided by Java EE/Jakarta EE and MicroProfile...
