Many diagrams use "OSP compute nodes" and OpenShift without indicating the OSP control and data planes, or label compute plane and compute nodes, with a data plane label. Some diagram should indicate clearly that the control plane exists inside OpenShift and the data plane outside, like https://sigs.centos.org/cloud/rdo_on_okd/introduction/
