Updated August 24, 2026 The control plane — API server, scheduler, controllers, etcd — is run by Raff. The single-master control plane is free; the HA control plane (3 masters) costs a flat $30/month. Workers and storage nodes are billed separately.

​
Standard vs HA

You can create a cluster with HA or upgrade later; upgrades are not reversible. HA covers VM- and host-level failures within the region. For production: enable HA, run workers across at least 2–3 nodes, and use ClusterIP Services behind Traefik ingress — a fully redundant ingress path with no standalone load balancer.

etcd on local NVMe

etcd is the one latency-critical component in Kubernetes: every write waits for an fsync. Raff places control-plane disks on hypervisor-local NVMe rather than network storage, keeping etcd fsync latency in single-digit milliseconds. The dashboard’s control-plane health card shows the live etcd latency p99 and 24-hour restart counts for your cluster — the same signals our own alerting watches.
