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.

MicroProfile and Service Mesh

When deploying into a Kubernetes cluster, some people choose to make use of a Service Mesh. The goal of a Service Mesh is to move certain considerations of microservices out of the application code and to place it around the application. A Service Mesh can remove some application concerns such as service selection, observability, fault tolerance, and, to a certain degree, security. One common Service Mesh technology is Istio. The way Istio works is by inserting a sidecar into the Pod for the containers and all inbound and network traffic is routed via that sidecar. This allows the sidecar to perform activities applying access control policies, routing requests to downstream services, and applying fault tolerance policies such as retrying requests or timing them out. Some of these capabilities overlap with some of the MicroProfile capabilities, for example, Istio can handle attaching and propagating OpenTracing data with requests. If you use Istio, you...
