In this short video Rudy de Busscher demonstrates how to use MicroProfile OpenTracing with Jaeger in combination with Payara Micro.

In this short video Rudy de Busscher shows how to connect MicroProfile Metrics with Prometheus and Grafana to produce useful graphics and to help investigate your microservice architecture.

In this short video, Rudy de Busscher demonstrates how to use MicroProfile Config with etcd.

Integration testing is perceived as difficult, time-consuming and requiring complex setup of 3rd party systems. There are different types of integration testing, such as system, acceptance and release testing, but all types of testing share the need to integrate several units of your application or other systems in your test.

The Java Virtual Machine comes in different flavors. On one hand, you have the OpenJDK based JVMs. Many vendors, including Oracle, RedHat, Amazon, and Azul to name just a few, create builds from the OpenJDK source to bring the JVM to your development machine or server.

Maybe you've already heard about Eclipse MicroProfile, or maybe you don't know what benefits it offers you in your current project. Perhaps you don't see the relationship with Java EE/Jakarta EE - or how you can use it with Payara Server or Payara Micro.

In this blog, I'll give you a short overview of all of the above questions so that you can start using MicroProfile in your next project on the Payara Platform.

Introduction

With Container orchestration tools like Kubernetes and Docker Swarm, you can add instances quite easily. Depending on the type of clustering you need or use for your application, some scenarios are easier to implement than others.

*Update* - The IntelliJ IDEA Payara Tools Plugin has been released and offers a better alternative to the solution discussed in this blog. Read more here about the Plugin.

If you want to run and debug your application from within an IDE using Payara Micro, you need to take different steps and use a different configuration then when you run the application with Payara Server. With Payara Micro, you can start the runtime from a jar file with no previous installation step. In this blog, I'll show you the steps to use IntelliJ IDEA with Payara Micro and how you can perform a hot reload of the application.

Introduction

Application updates are required as part of the normal maintenance process of your application lifecycle management. These updates should be as smooth as possible, and especially for a micro-services environment, performed with zero-downtime of your Payara Micro application. The Kubernetes Rolling Upgrades feature can help you with this.

In this blog, I'll discuss the basics around Kubernetes ConfigMaps and Secrets and give two examples of how you can use them in combination with Payara Micro.
