You can also provision downstream clusters using rancher. If the control-plane is hosted by a cloud-provider (gke/aks/eks) then that counts as provisioned. If you want to provision to bare-metal nodes, then you must use RKE, RKE2, or K3s.

Internally and historically we have referred to things as “provisioned” or “imported”, that page uses “launched” or “registered” for the same meanings.
