Supersonic Java Quarkus with Knative serverless

on YouTube ↗30m

" summary

Live demo builds a Quarkus app with Maven, shows 0.6s reload on code change, packages an uber JAR that uses about 96 MB JAR memory, then compiles a GraalVM native image (build takes minutes) that starts in ~10 ms and runs at 7 MB native RSS. The native binary is containerized, pushed to OpenShift/kubernetes, deployed with Knative Serving and autoscaling-to-zero (default 30s) and verified responding after scale-up; commands shown include mvn, docker/OCI image push and kubectl apply.
