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.

For two audiences
For enterprise buyers
See the gap portfolio you'd actually own
No vendor delivers a complete on-prem Fourth Cloud control plane. Every score below 4 is a gap you must own, close with a partner, or accept structurally. This instrument makes those gaps visible, nameable, and comparable.
For technology vendors
Pressure-test your platform story
The Fourth Cloud instrument scores functions, not vendors. A score moves when evidence moves. A structural gap becomes a Vendor roadmap gap only when a specific product with a confirmed timeline exists.
