Virtual nodes to auto-scale applications on Kubernetes

on YouTube ↗23m

" summary

Demo shows virtual nodes registering as Kubernetes nodes and running pods via Azure Container Instances so horizontal scaling happens without provisioning VMs, using ServiceMonitor for Prometheus, an HPA, a custom container that counts instances and a Grafana dashboard to view metrics. The presenter generates about 20 million requests to trigger rapid container creation, it starts in seconds, works with existing pod specs, but virtual kubelet lacks full kubelet features, is v1.0/CNCF-managed and ultimately still limited by backend CPU and memory.
