CCE Cloud Bursting Engine for CCI

Add-on Overview

The virtual-kubelet add-on is an implementation of the open-source Virtual Kubelet project. When momentary traffic spikes occur in CCE clusters, virtual-kubelet uses Huawei Cloud CCI to create pods for Deployments, StatefulSets, and jobs, eliminating the overhead of resizing CCE clusters. For details, see virtual kubelet.
