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.

We've now explored some of the benefits of having an operator help you out with both deployment and day 2 operations of a composite application to your Kubernetes cluster. While it is possible to deploy a given microservice without the use of an operator, having one guiding you is like having a co-pilot suggesting good default values where appropriate so that you get your application deployed with optimal configuration settings. And having one in the post-deployment stage, helping you with day 2 operations such as scaling, upgrading, and problem determination, ensures you have the best experience maintaining your application once it is in production use.

We've now covered all of the core MicroProfile features and have shown them in use in a real-world microservices-based application running in a Kubernetes platform such as OCP. Going forward, the remaining chapters will cover some of the auxiliary MicroProfile features (such as reactive messaging) and will look...
