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.

Platform as a Service

As the name suggests, a Platform as a Service (PaaS) is a software solution capable of providing platforms on demand. Those platforms can be any platform enable to expose services, such as database platform, Java platform, Java EE platform, .NET platform, Node.js platform, and much more.

Organizations having a PaaS can easily and quickly provide for their needs and business platform to run their application, processes, and manage everything from one single point.

In this chapter, we will cover the following topics:

An introduction to OpenShift
OKD (The Origin Community Distribution of Kubernetes)
OKD installation
Templates
Networking
Monitoring
