Securing Microservices with Auth0 and MicroProfile in Kubernetes without a hassle

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.

The Present and Future of Java at the GeeCon Conference 2019

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.

The Health Check Service In-Depth - Payara Server 5

This is an updated blog of the original which was published in May 2016

Payara Server provides the Health Check Service for automatic self-monitoring in order to detect future problems as soon as possible. When enabled, the Health Check Service periodically checks some low level metrics. Whenever it detects that a threshold is not met, it triggers alert notifications that allow to detect undesired behavior and predict possible failures. All of these automatic checks are very lightweight and run with a negligible impact on performance.

Payara Services at Oracle Code One 2019

This year marked the second edition of the Oracle Code One conference, which was formerly known as Java One. The conference is one of the most important Java conferences in the world and rightly so for many reasons! Which means that we at Payara couldn't miss being there. We were extraordinary busy at the conference, so we want to share with you a short summary of what happened, what it meant for Payara and for the whole Java community in general.

Tips for Building Cloud-Native Applications

An increasing number of organisations have moved, or are planning to move, to cloud-based hosting and are developing their applications to run in the cloud. However, once it's decided that your next application is going to run in the cloud, there are still a lot of architectural choices ahead of you. Besides obvious benefits like cost reduction, scalability and easier administration, cloud environments bring their own disadvantages and potential risks. In this blog, I'll share with you some tips on how to take care of the most important disadvantages and risks when you decide to build your applications for the cloud.

We will look at the various options for running your application:

Java 11 Support in Payara Server Coming Soon

The world is moving in fast forward and the Java ecosystem is no exception. In 2017, the release of Java 9 disrupted the Java ecosystem with the introduction of Java modules. Soon after, the new six months Java release cycle caused another disruption, with three new Java major versions released since then. The Payara team have been working hard to keep up with this new, faster velocity. Although the latest Payara Server version 5.191 doesn’t run on Java 11 yet, we’re very close and can confidently say the next version of Payara Server will run on Java 11.
