Practical Cloud-Native Java Development with MicroProfile

By: Emily Jiang, Andrew McCright, John Alcorn, David Chan, Alasdair Nottingham

Overview of this book

In this cloud-native era, most applications are deployed in a cloud environment that is public, private, or a combination of both. To ensure that your application performs well in the cloud, you need to build an application that is cloud native. MicroProfile is one of the most popular frameworks for building cloud-native applications, and fits well with Kubernetes. As an open standard technology, MicroProfile helps improve application portability across all of MicroProfile's implementations. Practical Cloud-Native Java Development with MicroProfile is a comprehensive guide that helps you explore the advanced features and use cases of a variety of Jakarta and MicroProfile specifications. You'll start by learning how to develop a real-world stock trader application, and then move on to enhancing the application and adding day-2 operation considerations. You'll gradually advance to packaging and deploying the application. The book demonstrates the complete process of development through to deployment and concludes by showing you how to monitor the application's performance in the cloud. By the end of this book, you will master MicroProfile's latest features and be able to build fast and efficient cloud-native applications.

Optional microservices and external services

There are also several optional parts of the example that you would only set up if you wanted certain extra bells and whistles available (such as having it send a tweet when you level up from SILVER to GOLD). Those parts have a dashed border in the architectural diagram.

Most people setting up the example skip many (or sometimes all) of the following pieces in the interest of simplicity. But each of these demonstrates how to do some additional things in a cloud-native manner, so they serve as good examples of how to utilize additional Java Enterprise Edition (EE)/Jakarta EE and MicroProfile technologies.

In this section, we will take a look at each of these optional microservices and their dependencies. The first of these is the alternate UI we saw earlier.


The more attractive UI is called Tradr. Its source code (the only non-Java microservice in the example) is a bit more complicated to read, but it provides a much more...
