Most businesses have been deploying containers and Kubernetes on top of VMs, which in turn sit on top of a hypervisor layer and a host OS on the hardware. While Kubernetes will happily orchestrate your containers regardless of the underlying servers, that doesn’t mean that choosing bare-metal servers over VMs has no impact on your Kubernetes environment. However, bare metal Kubernetes removes the VM layer and its hypervisor overhead and puts the Kubernetes installation directly on the host server’s operating system (OS). Deploying bare metal K8s provides several advantages including: better performance without a hypervisor layer, reduced licensing costs and complexity and improved cluster security and control.
