Red Hat is committed to the future of Java. It remains the most popular programming language runtime for enterprise application development, with nearly two-thirds of developers globally self-identifying as "moderate to heavy" users of Java. Java has consistently been in the top three programming languages on the TIOBE ratings for the past eighteen years. Safe to say - despite developers having more choice and easier access to new programming languages than ever before, Java remains the de facto standard for building business-critical applications. At Red Hat, our goal is to continue to support Java developers by offering new ways for Java developers to continue innovating.
There are a number of technologies driving Java into the cloud-native future, but one of the most promising is Quarkus, a framework for building Kubernetes-native Java applications. Quarkus is specifically designed to optimize Java for container environments, and as a result, it can significantly increase developer productivity and reduce operational costs, enabling it to be a key component in containerized workloads. Despite being an emerging technology, Quarkus has already become a significant player and is re-defining how developers do their jobs. Today, we are announcing that Quarkus is now included with Red Hat OpenShift, an important step for the future of bringing Java into modern cloud-native application development.
Quarkus on Red Hat OpenShift
Quarkus is already fully supported and available in Red Hat Runtimes, but we are excited to announce that now, Red Hat OpenShift customers also have access to Quarkus by it being available on OpenShift. Quarkus is natively integrated into OpenShift to make development even easier. This will offer developers familiar tooling, remote development on clusters using IDEs like CodeReady Workspaces, and integration with managed configuration, deployment of serverless workloads and managing application storage.
Quarkus contains several components for developing and deploying on OpenShift:
- A Quarkus extension that enables code generation for new projects, managing project dependencies, remote development and debugging, and easy 1-step deployment to OpenShiftPlugins for CodeReady Workspaces including pre-defined developer workspace stacks, configuration property suggestion and code completion, snippets for common Quarkus class types, and generating and deploying code to OpenShift directly from the IDE
- Automatic wiring of health checks, mounting of secrets, and exposing metrics for easy consumption by monitoring tools like Prometheus
- Automatic deployment of containerized Quarkus applications as an OpenShift Serverless workload
- One step Knative deployments
It also provides integration with the Kubernetes API, including a generic API client and support for dynamic application configuration using Kubernetes ConfigMaps and Secrets.
Migration Toolkit for Applications
Additionally, we have updated the Migration Toolkit for Applications to help bring Spring Boot applications to Quarkus and OpenShift. The tool, used by consultants, architects and developers, can help review your Java code or binaries to cover a wide set of transformation paths, based on battle tested rules, to modernize and migrate your applications. The latest version of the Migration Toolkit for Applications couples rules for Containerization, OpenJDK and Linux, with specifically developed and tested rules, that will help bring Spring Boot code to Quarkus on OpenShift, to better prepare for the hybrid cloud.
