Over the last weeks I've worked on an example application that demonstrates how Java EE developers can get started with microservices. The application is a full end-to-end sample which includes a web application, business logic, authentication and now also persistence. It runs on Kubernetes and Istio and there are scripts to easily deploy it. (more…)

I've been working on an example that demonstrates how to get started with cloud-native applications as a Java developer. The example is supposed to be a full end-to-end sample application which includes the topis authentication and authorization, since that functionality is required by most applications. This article describes how to check authorization in microservices implemented with Java EE and Eclipse MicroProfile. (more…)

This week I attended JAX in Mainz, Germany, which is a conference with 2000 enterprise developers. Below are some pictures. (more…)

Over the next weeks I'll give several talks how to get started with cloud-native applications implemented in Java. The talk is based on cloud-native-starter, which is an end-to-end application that demonstrates how to build microservices with Java and MicroProfile and how to deploy and run them on Kubernetes and Istio. (more…)

Over the last weeks I've worked on a new sample application which demonstrates how to build microservices-based architectures. While there are still some minor things I'd like to add, I think the sample is pretty comprehensive now and a good option for developers, especially Java EE developers, to learn microservices and cloud-native patterns. (more…)

My colleague Harald Ueble and I are working on a repo to help especially Java developers getting started with cloud-native applications. By doing this we have learned a lot ourselves. (more…)

When running cloud-native applications in the orchestration framework Kubernetes and the service mesh Istio, microservices need to report whether they are ready and live. Kubernetes needs to know this to restart containers if necessary. Istio needs to know this information to define where to route requests to. (more…)

As defined in the Twelve-Factor-App it's important for cloud-native applications to store configuration externally, rather than in the code since this makes it possible to deploy applications to different environments. (more…)

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 features for most applications is authentication and authorization. (more…)

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 can be collected automatically. (more…)
