Running Jakarta EE Applications like Cargo Tracker inside Kubernetes with Nested Container Architect
summary
Demo shows deploying Cargo Tracker on a Kubernetes cluster run inside system containers on the Jelestic PaaS using a nested container architecture, with Kubernetes nodes packaged and installed from a marketplace. JVM and container memory limits are adjusted automatically; example cluster set to a pay‑per‑use 1GB of 4GB limit while allowing instant lift to 7GB. Claims include higher density than VM hosts, easier vertical scaling without full VM buys, and live cross‑cloud migration demonstrated (Minecraft) with no user downtime.
