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.

Networking

OKD provides a routing layer to expose the application to the outside world. You can find the routing information of our example in the networking section on the right, labeled as Routes - External Traffic. You may have also noticed another element on the left, called Service - Internal Traffic, which is used by OKD for pod-to-pod communication. In that manner, different pods can talk to each other using the internal OKD network.

Services

If you click on a service name, a new page should appear, showing detailed information about how the application is internally visible and reachable, as follows:

The service page itself also references the route used by the system to expose the internal service. In this case,...
