Quarkus

A Kubernetes-native Java stack tailored for OpenJDK HotSpot and GraalVM, crafted from the best-of-breed Java libraries and standards.

Quarkus redefines Java for the cloud-native era by delivering ultra-low memory footprints and near-instant boot times (often under 0.02 seconds). It optimizes developer productivity through features like Live Coding and Dev Services, which automatically provision containers for databases or message brokers during development. By utilizing a container-first philosophy and compile-time boot techniques, Quarkus allows Java applications to compete directly with Go and Node.js in high-density environments like AWS Lambda and Kubernetes.
