Kubernetes on Bare Metal: When Raw Server Performance Beats the Public Cloud
For many teams, the first instinct when deploying Kubernetes is to spin up nodes in a public cloud. The flexibility is real, but a growing number of operators are revisiting bare metal servers for workloads that demand maximum efficiency. Research from Linux.com and aggregated analysis shows that running Kubernetes without a hypervisor can deliver measurable improvements in inter-pod network I/O and stateful workload performance, especially in clusters beyond ten nodes. This matters when you see recurring CPU throttling above 80%, RAM stuck in swap, or stable traffic above 80,000 visits per month. In this article we unpack what bare metal really means for Kubernetes buyers, where the performance gains come from, the operational tradeoffs, and how European hosting options fit in.
