If you’ve been hearing that Java/Jakarta EE is not Cloud-native or it’s difficult to get your Java/Jakarta EE applications running in the Cloud, watch this webinar to see why that’s not true and how you can continue using your existing Java/Jakarta EE development skills to modernize your application development!

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.

Jakarta EE Application Deployment to Kubernetes Cluster in Jelastic PaaS

Recently, Jelastic were asked to sponsor cloud hosting of a Jakarta EE project, called Cargo Tracker.

Being a member of Jakarta EE Working Group, Jelastic wanted to support the community and thus we started to run this application at one of our service providers (Scaleforce).

In this article, we would like to show how to deploy the Jakarta EE projects to the Kubernetes cluster within Jelastic PaaS using Cargo Tracker as an example.

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.

We explain a few features of Context and Dependency Injection (CDI). The CDI specification is an important backbone of Jakarta EE as it brings several specifications together. Over the years, it became more and more important as an increasing number of specifications started using CDI as the basis for it.

In this article, we will also tell you a bit about the different scopes, the interceptor mechanism, and the Event system.

Jakarta EE 9.1 Released!

The Jakarta EE Working Group Releases Jakarta EE 9.1 as Industry Continues to Embrace Open Source Enterprise Java!

Java Garbage Collection Types and Settings Customization via Jelastic PaaS

Performance and price are two big considerations in application hosting that always matter. And, often, we question ourselves on how to decrease the spends, without affecting the performance of your apps at the same time. In this article, we’d like to address automatic memory management for Java applications hosted with Jelastic using garbage collection.

Let’s clarify what garbage collection is, what it does for Java applications and how it works within Jelastic PaaS.
