See the idea
Bare metal gives engineers direct control over GPU, network, and virtualization layers, but it shifts elasticity and lifecycle work onto the team. This trade-off map shows when that bargain pays off.

Hosted control planes for Red Hat OpenShift, based on the HyperShift project, decouple the cluster control plane from worker nodes by running control-plane components as pods inside a central management cluster. On bare-metal infrastructure, OpenShift Virtualization provisions worker nodes as virtual machines, enabling live migration and reducing hardware requirements. The article presents a declarative GitOps workflow using Helm templates and an Argo CD ApplicationSet that dynamically generates deployments from tenant-specific YAML configuration files in Git. Prerequisites include a bare-metal management cluster with OpenShift Virtualization, Red Hat Advanced Cluster Management, and OpenShift GitOps, plus networking configured with NMState, Multus CNI, and MetalLB. The approach achieves a “Cluster-as-a-Service” model where provisioning a production-grade cluster requires only a Git push.
