In the context of cloud-native applications the topic 'reactive' becomes more and more important, since more efficient applications can be built and user experiences can be improved. If you want to learn more about reactive functionality in Java applications, read on and try out the sample application and the two new workshops. (more…)

This article describes Tekton, an open-source framework for creating CI/CD systems, and explains how to deploy microservices built with Eclipse MicroProfile on Kubernetes and OpenShift. (more…)

Yesterday I presented in a Jakarta Tech Talk 'How to develop your first cloud-native Applications with Java'. Below is the recording and the slides. (more…)

Open Liberty is a flexible Java application server. It comes with Eclipse MicroProfile which is a set of tools and APIs to build microservices. With these technologies I have created a simple hello world microservice which can be used as template for your own microservices. In this article I describe how to deploy it to OpenShift. (more…)

OKD, the open source upstream Kubernetes distribution embedded in OpenShift, provides several ways to make deployments of applications to Kubernetes for developers easy. I've open sourced a project that demonstrates how to deploy local Open Liberty applications via two simple commands 'oc new-app' and 'oc start-build'. (more…)

Over the last weeks I've worked on an example application that demonstrates how to develop your first cloud-native applications with Java/Jakarta EE, Eclipse MicroProfile, Kubernetes and Istio. Based on this example my colleague Thomas Südbröcker wrote a workshop which explains how to implement resilient microservices, how to expose and consume REST APIs, how to do traffic management and more.

At WeAreDevelopers Harald Uebele and I gave a 30 minutes talk 'How to develop your first cloud-native Applications with Java'. Below is the recording and the slides. (more…)

The repo cloud-native-starter contains an end-to-end sample application that demonstrates how to develop your first cloud-native applications. Two of the microservices have been developed with Java EE and MicroProfile. To simplify the creation of new Java EE microservices, I've added another very simple service that can be used as template for new services. (more…)
