For cloud native applications, Kubernetes and Istio provide a variety of key functionality that works generically for microservices out of the box, regardless of the language they are implemented in and without changes to the application logic. However, some functionality can not be covered by orchestration frameworks and service meshes, they must be handled in the business logic of the microservices, e.g. application-specific failover functionality, metrics, and fine-grained authorizations.
In this session, we’ll use a concrete example to show how to create microservices with JavaEE and Eclipse MicroProfile and how to roll out and run them on Kubernetes and Istio. MicroProfile itself has some convenient features that are typically needed in the development of microservices, such as: calls to REST APIs and implementation of REST APIs, including their documentation. For this session, we use our example code "cloud-native-starter", which we have released on GitHub as open source, along with scripts for fast deployment to Minikube and lots of instructions and information.
