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.

For some time now there has been an undeniable growth of interest for Microservices. The core concept itself, however, is not that new.

All companies are software companies, and businesses will always experience the challenge of keeping integrations between users and applications scalable, productive, fast, and of high quality. To combat this, cloud, microservices, and other modern solutions come up more and more in architectural decisions. Here is the question: Is Java prepared to deal with these diverse concepts in a corporate environment?

MicroProfile Health is an API designed specifically for use in cloud and containerized environments, where you want to quickly determine if an instance of an application is unhealthy and restart it. How exactly do you use it though? In this session, I’ll run through how to add some health checks to your application, and how to configure a number of cloud providers and containers to effectively use them to restart your application instances.

In this day and age, securing enterprise platforms is a challenge that developers and consultants tackle in an uninformed manner, producing subpar solutions in most cases. To combat this pattern, third-party security services such as Auth0 have been devised to externalize the security of services, and they focus on stable implementations of common enterprise use cases (identity management, OAuth compatibility, and so on), and platforms such as Eclipse MicroProfile allow for their easy integration with enterprise Java microservices. Moreover, in combination with Kubernetes, MicroProfile is a very powerful tool to simplify securing microservices, monitoring them and creating reproducible deployments.

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.

Each year, there's one special Java conference for me. It's GeeCon in Prague because Prague is my home city where I work and live and where I know so many great people in the Java community. This year, I had the opportunity to be a part of GeeCon again as a speaker. As is true every year, GeeCon was well organized, with a lot of interesting international and local speakers and a huge crowd of passionate attendees. All of this made the conference exceptional and worth attending.

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.
