Control plane and infrastructure nodes are deployed and managed by Stakater. Shutting down the underlying infrastructure through the cloud provider console is unsupported and can lead to data loss. There are at least 3 control plane nodes that handle etcd- and API-related workloads. There are at least 2 infrastructure nodes that handle metrics, routing, the web console, and other workloads. You must not run any workloads on the control and infrastructure nodes. Any workloads you intend to run must be deployed on worker nodes.

!!! Note:
!!! note

Approximately one vCPU core and 1 GiB of memory are reserved on each worker node and removed from allocatable resources. This reservation of resources is necessary to run processes required by the underlying platform. These processes include system daemons such as udev, kubelet, and container runtime among others. The reserved resources also account for kernel reservations.
