Fourth Cloud — On-prem control plane assessment

Function-by-function scoring of on-prem control planes against the Fourth Cloud operational model: VMware Cloud Foundation, IBM / Red Hat OpenShift, Nutanix Cloud Platform, and Oxide Cloud Computer. Each vendor is scored on FC-0 through FC-4 layers plus identity plane continuity.

Enterprise on-prem control planes, scored against the Fourth Cloud operational model.

On-prem control planes assessed against the Fourth Cloud operational model. Function-by-function scoring (0–4), gap ownership classification, and a top-level identity plane continuity finding for each vendor — calibrated against the AWS hyperscaler benchmark.

Part of the Layer2C research system

Fourth Cloud is the readiness instrument in a four-part system. It scores on-prem control-plane readiness, not vendor authority, and its scores don't map one to one onto the 4+1 layers. System map →
