The Next Evolution of Java: ☕️ Achieving Hyper Performance and Efficiency in Cloud Native Workloads

on YouTube ↗53m

" summary

Compares concrete techniques: Quarkus + Jib for minimal images, GraalVM Native Image for tiny cold starts (example build ~25–30s with ~2–3GB peak build RAM producing a ~51MB native binary), CRaC for 200–300ms JVM resume, and CDS class-data-sharing to avoid repeated class parsing. Measured numbers: JVM startup ~300–340ms and ~130MB RSS, native startup ~33ms and ~10MB RSS, Kubernetes scale‑out hits ~100 replicas in under 10s. build time and peak RAM tradeoffs native reduces footprint and cold start
