Kubernetes-native operations

Hypervisors, storage clusters, and network configuration managed declaratively through Kubernetes operators and Helm - no manual runbooks.

OpenStack cloud APIs

Nova, Neutron, Cinder, Keystone, and Glance provide the cloud APIs your users and automation tools already know.

High availability by default

Automatic hypervisor evacuation, Ceph stretched clusters with Arbiter quorum, and OVN-based networking for resilient VM workloads.

Intelligent placement

Cortex enriches Nova scheduling with real-time cluster state for better resource utilization and workload performance.

Full observability

Prysm, Prometheus, and Perses provide metrics, alerting, and dashboards across every layer of the stack.

Aurora management frontend

A unified UI for managing VMs, networks, and storage - backed by Greenhouse for team-scoped monitoring and operations.
