A change in the year means a change in our version number! Slightly later than our usual release month of February, we've tried to include some more changes in the release than a simple number change to make the wait worthwhile: read on to find out more!

What is Docker?

Docker is a platform which makes it easier to create, deploy and run your applications using containers. A container bundles all the software needed to run it. By packaging the required dependencies, it makes it easy to run it on any machine, regardless of small configuration differences.

I have written and talked a lot about why reactive programming matters. It’s always been a topic of personal interest for me. I’m not only an engineer but also a perfectionist and I’ve always wanted my applications to be perfect, easy-to-use and pleasant to work with. Building reactive applications is one way to achieve this perfection.

As 2019 is in full swing, let's reflect on the highlights of improvements for the Payara Platform in 2018 and review the plans for enhancements and changes coming in 2019.

The Payara Support Lifecycle policy ensures longevity of your Payara Server or Payara Micro (The Payara Platform) investment. We provide 10 years of support and a well-defined lifecycle model to maintain the stability of your production environment.

Starting in February 2019, Payara Server 4 and Payara Micro 4 are moving from Full Support to the "Maintenance" stage of the lifecycle. No new features, enhancements, or APIs will be released for the Payara Platform 4 after February. What does this mean for you? Should you upgrade to Payara Platform 5?

This is an update of the article "How to Upgrade Payara Server."

Since Payara Server is on a regular and frequent release cycle, we get a lot of questions on how to upgrade to the latest version while maintaining existing domain configurations.

Hazelcast in the Payara Platform offers several ways to configure how instances cluster. One new way is by using DNS records.

There has been a lot of noise around MicroProfile for quite a while now, and one of the specs provided by MicroProfile are Health Checks. The aim of this spec is to allow you to write a number of health checks that will run when you hit a specific endpoint, the intention being that this endpoint can be periodically poked by a container orchestrator to determine if an instance is responsive and healthy.
