Red Hat introduced Quarkus, a Kubernetes Native Java framework tailored for GraalVM and HotSpot, crafted from best-of-breed Java libraries and standards.
The goal of Quarkus is to make Java a leading platform in Kubernetes and serverless environments while offering developers a unified reactive and imperative programming model to optimally address a wider range of distributed application architectures.
Quarkus is a lightweight, high performance framework that is designed to significantly reduce the footprint and latency of Java applications, specifically for cloud-native architectures like microservices, containers and serverless.
Quarkus delivers significant runtime efficiencies (based on Red Hat testing), such as:
- Fast Startup (tens of milliseconds) allows automatic scaling up and down of microservices on containers and Kubernetes as well as FaaS on-the-spot execution
- Low memory utilization helps optimize container density in microservices architecture deployments requiring multiple containers
- Smaller application and container image footprint
Most Java developers are familiar with the imperative programming model and would like to utilize that experience when adopting a new platform. At the same time, developers are rapidly adopting a cloud native, event-driven, asynchronous, and reactive model to address business requirements to build highly concurrent and responsive applications. Quarkus is designed to seamlessly brings the two models together in the same platform, resulting in strong leverage within an organization.
Quarkus also offers developers:
- Unified configuration with all configuration in a single property file.
- Zero config, live reload in the blink of an eye
- Streamlined code for the 80% common usages, flexible for the 20%
- No hassle native executable generation
Quarkus brings a cohesive, fun-to-use full-stack framework by leveraging best of breed libraries you love and use wired on a standard backbone – these include Eclipse MicroProfile, JPA/Hibernate, JAX-RS/RESTEasy, Eclipse Vert.x, Netty, and more.
Quarkus also includes an extension framework that third-party framework authors can leverage to extend it. The Quarkus extension framework reduces the complexity for making third-party frameworks run on Quarkus and compile to a GraalVM native binary.
