Java was introduced 25 years ago and to this day, remains one of the most popular programming languages among developers. By adding Quarkus as a supported runtime, Red Hat is helping to bring Java into the modern, cloud-native application development landscape and to approaches like microservices, containers and serverless that are enabling organizations to push the envelope on productivity, efficiency, agility and scale, and enabling Java developers to continue working in the language they know and love. With Quarkus, users are getting a fully Red Hat supported technology, which includes an active community, continuous updates, and a fast release cadence.

As a full-stack, Kubernetes-native Java framework that has been optimized for memory density and rapid startup time, Quarkus enables organizations to advance existing application environments and extend years of investment in Java for mission-critical systems. The open source project has been crafted from a selection of leading Java technologies and standards, and offers developers an adaptable development model that is designed to combine both imperative and reactive styles in a seamless, unified user experience.

Quarkus helps to:

  • Increase developer productivity: Quarkus works out of the box with popular Java standards, frameworks, and libraries, alleviating the need to learn new APIs or switch to another programming language altogether. It also provides a number of features such as live coding and unified configuration for faster iteration during development, where code changes are automatically and immediately reflected in the running app.
  • Increase operational efficiency: Quarkus is tailored for a modern, Kubernetes-native development stack, enabling organizations to deliver business solutions faster and in a more streamlined manner, maintain a competitive edge and speed up the overall time to market.
  • Increase cost savings: Quarkus has a low memory consumption and a fast startup time. This translates into better resource utilization and end user experience, with new applications and services instantly available. This efficiency leads to a high density of workloads per CPU, also translating to increased cost savings.
  • Increase reliability: Quarkus applications are elastic, scalable, and able to meet changing demand, translating to a more reliable system.

Red Hat has long been a leader in the Java community, and remains committed to moving Java forward through open, community-driven innovation. Today, Red Hat furthers this commitment with the addition of Quarkus to the fully supported Red Hat Runtimes. Red Hat Runtimes provides best-in-class integrated products, migration tools, and components to create cloud-native applications while also speeding up development and delivery time. Red Hat Runtimes offers developers and architects the choice of the right tool for the right task, through a collection of lightweight runtimes and frameworks for highly-distributed cloud architectures, like microservices, with in-memory caching for fast data access, and messaging for quick data transfer between existing applications.

Quarkus includes an extension library that incorporates a vibrant ecosystem of more than 200 extensions standards, libraries, services, and technologies. The library includes a number of cloud-native frameworks and tools such as RESTEasy, Hibernate, Eclipse MicroProfile, and more. It also includes extensions for several Red Hat cloud services such as Red Hat AMQ Streams, Red Hat AMQ Broker, Red Hat Fuse, and business automation.

Quarkus as a supported Red Hat Runtime is now generally available.
