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.

Jakarta EE - the New Open Source Life of Java EE

We are living in a new era of information technology. All people like me, who started work at the beginning of the 2000s, have gone through a constant but gradual evolution of languages, frameworks, and architectures. The last year has marked a great change in the way we approach a software release.

The great competition that drives the global market has changed the cultural approach of companies, which now have a milestone target—the reduction of time to market. The need to release a new business service as soon as possible is the main target of a company, regardless of their business area.

From an information technology point of view, this need has been translated into a complete review of development platforms and their updating and evolution processes.

From an enterprise point of view, this change, defined as digital disruption, is leading to the need to review company structures with regard to the organization of roles and skills, as well as to the policies of continuously updating to keep up with market needs. The community side of developers has led to a conceptualization of ideas as has not been seen for some time.

The best way to comprehend all the ideas that are being born around these concepts is through the open source model.

In this chapter, we will cover the following topics:

  • Open source
  • The Java programming language
  • OpenJDK 9 and 10
  • Java EE – MicroProfile.io – Jakarta EE
