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.

Transactions in microservices architecture

The benefits related to microservice architectures are there for all to see, from the reduction of the time to market, to the simpler management of the source life cycle, to the punctual management of resources, according to the actual workload.

However, at the end of every discussion on microservices, before proceeding to the design of the application architecture, a question always comes up—how are the transactions managed within microservices?

Distributed system interactions can be complex for many reasons, some of which are as follows:

  • A microservices architecture involves many parties, realized using different technologies that adhere to different specifications
  • A business function can span many different organizations that can have different service-level agreements, and, for this reason, can be implemented with various...
