node-fleet-heterogeneous-runtime-model

Status: IN

The OpenShift node fleet is fundamentally heterogeneous: RHCOS nodes follow an immutable rpm-ostree model with operator-mediated changes, while Windows nodes use an entirely different container runtime (not CRI-O) and require OVN-Kubernetes hybrid networking — operational procedures, troubleshooting, and capacity planning must account for this runtime divergence.

Justifications

depth-2 — RHCOS and Windows nodes have incompatible runtime models coexisting in one cluster

Depends on (SL): rhcos-immutable-update-model, windows-node-architectural-divergence
