The Engine Room

Technical advantages engineered from bare-metal up for resilience, performance, and true sovereignty.

🔒

Hard Multi-Tenancy

True VPCs, Not Just VPS.

Every instance is isolated via KVM hypervisors. Build complex Layer 3 topologies, floating IPs, and private subnets powered by OVN.

Upstream Kubernetes

No Walled Gardens.

Deploy fully compliant, unmodified K8s clusters. Bring your own CNI (Cilium/Calico) and Ingress. You control the control plane.

Ceph NVMe Storage

Distributed by Default.

Cinder CSI is baked into every cluster. When your pod requests a volume, our NVMe Ceph cluster provisions it instantly with LUKS encryption at rest.
