Control plane
Typically, Kubernetes clusters have Nodes with different roles, one being to host control plane components. The most important ones being: - etcd - apiserver - controller-manager - scheduler - cloud-controller-manager
MetaKube takes a different approach and manages these components in SysEleven infrastructure and only exposes the apiserver behind a load balancer.
This comes with better flexibility, enhanced security and is more robust. But since Nodes don't all share the same network, it adds a few challenges.
