Platform & DevOps·The orchestrator's model of the world
the nodes running your containers and the proxies moving the packets keep working whether or not anyone is watching them.
Data plane
Also calledworker plane, workload plane
The components that actually carry the work: the nodes running containers, the proxies forwarding requests, the storage serving reads. It is the part users experience, and it is designed to keep running from its last known instructions when the control plane is unavailable. Separating the two planes is the reason a managed cluster's upgrade can be boring and the reason a control-plane incident is measured in inability to change rather than in downtime.
