Yeah, especially in production bare metal clusters. If you want N+2 redundancy that's at least 5 physical machines for just the control plane (etcd & apiservers), more if you don't want to colocate worker nodes with that...

Even if you have full bare metal automation and thousands of machines that seems like unnecessary waste.

Add the cost of administrative services: DNS resolvers, ingress controllers, log forwarders, monitoring (e.g. Prometheus, some exporters), autoscalers, tracing infrastructure, admission controllers, backups/disaster recovery tools (e.g. Velero)...

It can add up to millions per year if you aren't auditing your costs.
