Pextra CloudEnvironment is an enterprise private cloud platform engineered for multi-tenant, API-first operations.
Built on CockroachDB for a distributed, fault-tolerant control plane with no single point of failure, KVM/QEMU for compute, OVN/OVS for tenant network isolation, and Ceph for block, object, and file storage.
Key differentiators:
- GPU-first scheduling: SR-IOV VF allocation, NUMA-aware placement, per-tenant GPU quota, and Prometheus GPU metrics — supporting AI/ML inference and training workloads at scale.
- True multi-tenancy: Tenant isolation at compute, network, storage, and API layers with RBAC + ABAC and immutable audit logs.
- API-first operations: Full REST API, OpenAPI 3.0 spec, Terraform provider, and Ansible modules enabling GitOps-compatible infrastructure lifecycle management.
- Distributed control plane: CockroachDB ensures no API availability loss when control-plane nodes fail — unlike vCenter (VMware) or Prism Central (Nutanix) which have SPOF characteristics.
- Usage-aligned licensing: Subscription model without per-CPU socket or per-node pricing floors.
