In April, the Node.js development team released Node.js 14. This major version release, code-named Fermium, will become a long-term support (LTS) release in October 2020.

We are always looking for ways to understand better how developers create, build, manage, test, and deploy applications on and for Red Hat OpenShift. An important part of that effort is the annual OpenShift Developer Survey, which we’ve just released for 2020.
Keep reading to learn more about the survey, including highlights of the 2019 survey results and what to expect from the survey this year. We also invite you to participate in our OpenShift developer experience office hours and one-to-one feedback sessions for our developer community and customers.

The release of Red Hat Data Grid 8.1 offers new features for securing applications deployed on Red Hat OpenShift. Naturally, I wanted to check them out for Quarkus. Using the Quarkus Data Grid extension made that easy to do.
Data Grid is an in-memory, distributed, NoSQL datastore solution based on Infinispan. Since it manages your data, Data Grid should be as secure as possible. For this reason, it uses a default property realm that requires HTTPS and automatically enforces user authentication on remote endpoints. As an additional layer of security on OpenShift, Data Grid presents certificates signed by the OpenShift Service Signer. In practice, this means that Data Grid is as secure as possible out of the box, requiring encrypted connections and authentication from the first request. Data Grid generates a default set of credentials (which, of course, you can override), but unauthenticated access is denied.
In this article, I show you how to configure a Quarkus application with Data Grid and deploy it on OpenShift.

When OpenJDK‘s Java virtual machine (JVM) runs a Java application, it loads a dozen or so classes before it starts the main class. It runs a method several hundred times before it invokes the optimizing compiler on that method. This preparation is a critical component of Java’s “write once, run anywhere” power, but it comes at the cost of long startup times.

In the first half of this article, I introduced Tekton as a framework for cloud-native CI/CD pipelines, and Argo CD as its perfect partner for GitOps on Red Hat OpenShift. Our example for the demonstration is a Knative service that deploys and serves a Quarkus application. Our goal is to develop a complete continuous integration and delivery process, which begins when a commit is initiated in the application’s GitHub repository and ends with the new application version deployed in the development, staging, and production environments.

Red Hat CodeReady Workspaces 2.4 is now available. For this release, we focused on adding support for IBM Z and improving the IDE editor and configuration elements.

DevNation Tech Talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions plus code and sample projects to help you get started. In this talk, you’ll learn about testing Quarkus applications and services from Alex Soto Bueno and Burr Sutter.

In this article, we introduce a new utility for developers who want to ensure that their code transitions cleanly from upstream Kubernetes to Red Hat OpenShift. OpenShiftKubeAudit (KubeAudit) is a static analyzer that semantically checks a user’s code for known incompatibilities so you can fix them before bringing the code into OpenShift. KubeAudit is also simple to use and easy to extend.
This being the first release, KubeAudit currently offers only a handful of audits, but they’re easy to write. We’re looking for feedback and additional use cases from the community to help make the tool more comprehensive.

When moving an application that you’ve compiled on Red Hat Enterprise Linux (RHEL) 7 to RHEL 8, you will likely encounter issues due to changes in the application binary interface (ABI). The ABI describes the low-level binary interface between an application and its operating environment. This interface requires tools such as compilers and linkers, as well as the produced runtime libraries and the operating system itself, to agree upon the following:

Red Hat Runtimes now supports the new Open Liberty 20.0.0.10 Java runtime. Open Liberty 20.0.0.10 features support for the Automatic Certificate Management Environment (ACME) protocol, which automates the process of obtaining a certificate signed by a certificate authority (CA). The Open Liberty 20.0.0.10 release also includes many bug fixes.
