Introduction to New AutoScale Feature Available in Payara Server
When AutoScale is fully developed, not only will it allow you to change the number of instances in the Deployment Group by implementing additional asadmin commands, but it will also signal the routing systems of the changed configuration and automatically trigger a change in size based on rules around resource usage.
In this first step of the AutoScale development, we have introduced the concept of the Scaling Group into Payara Server Community Edition 5.2021.4 which can alter the number of instances in a Deployment group and implement it for SSH nodes.
The AutoScale feature is in continuous development, with improvements and additional functionality (including addressing the routing issue) planned in our future releases.

Automatic WildFly Clustering in Managed Domain Mode and Scaling inside Containers
How to extend WildFly from standalone server to cluster in managed domain mode inside containers for running cloud-native scalable applications?
There is no need to rebuild the whole application architecture in order to gain the required outcome from both managed domain mode and container technology.
Migration of legacy projects from VMs to micro clusters with system containers is not that painful at all.
It brings a “rich taste” of flexibility and efficiency for increasing competitive advantage.

Getting Started with Jakarta EE 9: Context And Dependency Injection (CDI)
In this article of the Getting Started with Jakarta EE series, we look at various specifications and how you can use them in your next application.
