6-22-23 - [Pittsburgh JUG] - Intro to Quarkus

Quarkus is a Kubernetes-native Java framework tailored for building cloud-native applications and serverless functions with small memory footprint and fast startup time. Quarkus is the rising star for cloud-native Java as it re-imagines the Java stack to give you the performance characteristics and developer experience you need to create modern, high performing applications. Quarkus helps you use your existing skills and code in new ways and greatly reduces the technical burden when moving to a cloud-native environment.
