Private GPU Cloud Kubernetes for AI Providers

Deliver fully isolated, CNCF-certified tenant clusters on your GPU infrastructure. vCluster virtualizes K8s control planes so every tenant gets their own API server without provisioning separate physical clusters.

Problem

The GPU Cloud Kubernetes Problem

Standard Kubernetes forces a painful choice between strong tenant isolation and operational efficiency.

Namespace Isolation Is Too Weak

Standard Kubernetes namespace isolation exposes cluster-wide agents and other tenants' nodes to workloads that should never see them.

Separate Physical Clusters Cost Too Much

Provisioning a dedicated cluster per tenant multiplies hardware, operational overhead, and time to revenue at every new customer.

DIY Platform Takes Too Long

Building a private GPU cloud Kubernetes platform in-house takes 6 to 10 engineers, 6 to 12 months, and over one million dollars.

Solution

Tenant Clusters Without Physical Cluster Overhead

vCluster virtualizes the Kubernetes control plane itself, running fully isolated, CNCF-certified tenant clusters as lightweight pods inside your host cluster. Every tenant gets a dedicated API server, etcd, and RBAC on your private GPU cloud Kubernetes infrastructure with near-zero marginal cost per tenant. Production-proven across 100K+ GPU nodes and 50+ GPU clouds.

Built for Private GPU Cloud Kubernetes

A complete stack from bare metal provisioning to tenant cluster orchestration to kernel-native workload isolation, purpose-built for GPU cloud providers.

Tenant Isolation

Isolated Tenant Clusters as Lightweight Pods

Each tenant on your private GPU cloud Kubernetes environment gets a fully dedicated control plane running as a pod. Own API server, etcd, scheduler, and RBAC. Spins up in seconds with near-zero overhead per tenant.

  • Own API server and etcd per tenant
  • Spins up in seconds
  • Near-zero marginal cost per tenant
Bare Metal

Zero-Touch GPU Server Provisioning

PXE boot, OS installation, machine registration, and network automation handled automatically. vMetal takes GPU racks from physical delivery to production-ready Kubernetes nodes with no manual intervention.

  • PXE boot and OS install automated
  • Full GPU server lifecycle management
  • Network automation via Netris integration
Hardware Isolation

Fully Dedicated Nodes Per Tenant

Assign dedicated physical GPU nodes to a tenant with their own CNI and CSI. No other tenant workloads share the hardware. Complete hardware-level isolation for your most demanding enterprise customers.

  • Dedicated physical GPU nodes per tenant
  • Own CNI and CSI stack
  • No cross-tenant workload bleed
Workload Security

Kernel-Native GPU Workload Isolation

vNode (currently in private beta) places every workload in its own secure runtime using seccomp, cgroups, namespaces, and AppArmor. Container breakout protection at bare metal GPU performance with no hypervisor tax.

  • Prevents container breakout attempts
  • No hypervisor overhead on GPU
  • Compatible with gVisor and Kata Containers
AI Environments

Pre-Certified AI Platform Environments

Turn a bare tenant cluster into a production AI platform in minutes with pre-validated environments for Run:AI, Ray, and Jupyter. Skip weeks of integration work and deliver managed AI services on day one.

  • Run:AI, Ray, Jupyter pre-validated
  • Cluster to AI platform in minutes
  • Certified with tenant isolation layer

FAQs

What makes vCluster different from standard Kubernetes multi-cluster management?

vCluster virtualizes the Kubernetes control plane itself rather than managing separate physical clusters. Each tenant on your private GPU cloud Kubernetes infrastructure gets a real, CNCF-certified API server running as a lightweight pod inside a single host cluster. This means you avoid the cost and provisioning delay of physical clusters while still giving every tenant full cluster-admin, their own CRDs, and complete RBAC isolation. Over 40 million tenant clusters have been created using this approach in production.

How does vCluster handle tenant isolation for GPU workloads?

vCluster offers a full isolation spectrum: shared nodes with resource quotas, private nodes with dedicated hardware and separate CNI and CSI, and dedicated nodes that eliminate noisy-neighbor GPU contention. At the workload level, vNode (currently in private beta) adds kernel-native isolation using seccomp, cgroups, and AppArmor to prevent container breakouts without introducing hypervisor overhead. GPU performance is preserved at the bare metal level throughout.

Can vCluster deploy directly on bare metal GPU servers?

Yes. vCluster Standalone runs as a single binary directly on Linux bare metal with no dependency on k3s, kubeadm, or any existing Kubernetes base layer. vMetal extends this with zero-touch provisioning: PXE boot, OS installation, machine registration, and network automation from rack to production. Lintasarta launched Indonesia's leading GPU cloud in 90 days using this stack with 170 or more tenant clusters in production.

How quickly can a GPU cloud provider go live with managed Kubernetes?

Boost Run launched a managed Kubernetes offering in under 45 days with zero new platform engineering hires using vCluster. The full stack from bare metal provisioning through tenant cluster orchestration to AI-ready environments is designed to compress what traditionally takes 6 to 12 months of internal engineering into weeks, avoiding the multi-million dollar build cost of a DIY private GPU cloud Kubernetes platform.

Is vCluster Kubernetes conformant for enterprise GPU cloud customers?

Every tenant cluster provisioned by vCluster is a CNCF-certified Kubernetes distribution with 100 percent API compatibility. Enterprise customers get the same Kubernetes API they use on AWS EKS or Google GKE, with full cluster-admin access to install their own CRDs and configure RBAC. vCluster is also named in the NVIDIA DGX SuperPOD reference architecture and in SemiAnalysis ClusterMax evaluation criteria.

What GPU cloud providers and enterprises use vCluster today?

vCluster powers infrastructure for more than 50 GPU clouds and Fortune 500 customers, including CoreWeave and Nscale on the GPU cloud side and JPMorganChase and Adobe on the enterprise side. The platform has proven scale across 100 thousand or more GPU nodes and 1 million or more CPU nodes in production, underpinning managed Kubernetes services and internal AI factory deployments worldwide.
