As part of the new features introduced with the release of Payara Server 162, you can now form a cluster of Payara Server instances using the concept of Hazelcast “Lite Nodes”. This can help you create more flexible cluster topologies.

Payara Server 163 is about to be released in a couple of days, as usual with many improvements and bug fixes. Although it cannot match the previous release in the number of new features, the list of improvements and fixes in Payara Server 163 is already longer than in the current release!

The recording of the Payara Team Q&A session, broadcasted live on Wednesday the 20th of July, is now available to watch on YouTube!  Payara Engineering and Development Team answered questions from the community (listed below) and discussed Payara Server, Payara Micro, future releases, upcoming features, best practices, use cases and more.

In this short video recap, Ondrej Mihalyi ( @OMihalyi )- Payara Support Engineer – gives you an overview of the Payara Server 162 Release Notes. Tune in to find out more about the most useful developer and operations features in Payara Server and Payara Micro 162, Payara Documentation update, new Docker images, new demos, how to contribute and more.

Payara Micro allows you to run web applications in a self-contained and easy way. Since the release of the Payara Server in May 2016, there is a simple way to generate an "Uber" JAR that bundles the contents of a WAR file and the classes and resources that compose Payara Micro!

Note that this "Uber" Jar is not the best way to run your application in a Docker container as it requires an update of the entire binary for each small code change you make in the application. A better solution is just to start a Payara Micro Instance and point to the application that needs to be installed. More information can be found on our Payara Micro Docker Image documentation.

The HealthCheck Service provides automatic self-monitoring in order to detect future problems as soon as possible. The HealthCheck Service was introduced in Payara Server and Payara Micro version 161 and some new metrics have been added in version 162.

All the functionality of the HealthCheck Service that is available in Payara Server is also included in Payara Micro. However, as Payara Micro differs in some concepts from Payara Server, the usage and configuration of the HealthCheck Service is slightly different. In this post, we will focus on how to use it in Payara Micro.

Payara Micro 162   can now deploy your artifacts stored in Maven repositories simply by providing the GAV coordinates. This should provide another option for continuous delivery scripts! 

A year ago, we brought you our first Docker images. Today, we have updated them with a few changes and refinements.

For those already familiar with Docker, here are the key points:

One of the most exciting new features in the Payara Server 162 release is the Asadmin Recorder - a tool especially useful for the Operations Teams! 

Asadmin Recorder allows you to create runnable scripts of asadmin commands that mirror configuration done in the administration console.  Have a look at our video walkthrough below for a quick overview of this new Payara Server feature.
