As some of my readers will know, I’m working on a cloud-native-starter repo that demonstrates how to start building cloud-native applications with Java EE and Istio. One of the required core featur...

For cloud-native applications Kubernetes and Istio deliver a lot of important functionality out of the box, for example certain metrics which are independent from the actual service implementations...

Istio is an open source service mesh to connect and control microservices in cloud native applications running on Kubernetes. One of the key features is traffic management for A/B testing, canary r...

Yesterday Harald Uebele, Thomas Südbröcker and I presented Blue Cloud Mirror in an IBM Developer webinar. Below are the slides and the recording. Blue Cloud Mirror is a game where players need to ...

This week I’ve attended JavaLand, a developer conference in Germany with 2000 attendees. It has been the fourth time I’ve been there and, as always, it has been a great pleasure. We had a booth whe...

Last week Red Hat introduced the open source framework Quarkus which promises fast boot times and low memory usages. This makes Quarkus interesting for Java workloads running as serverless function...

Previously I blogged about how to implement and document REST APIs in JavaEE applications with Eclipse MicroProfile. In this article I describe the inverse scenario how services can invoke other se...

Quarkus is a “next-generation Kubernetes native Java framework” which is available as open source. Quarkus promises fast boot times and low memory usages. This makes Quarkus a perfect fit for Java ...

The standard way to implement REST APIs in JavaEE applications is JAX-RS. The de-facto standard for API documentation is OpenAPI (formally Swagger). Eclipse MicroProfile supports developers to use ...
