vCluster — Kubernetes Tenant Isolation for AI Infrastructure

Create & Manage Tenant Clusters Like a Hyperscaler

Launch your Kubernetes platform in days
Automate tenant and infra provisioning
Ensure strict isolation, including hardware isolation on bare metal infra

Unlock more revenue with a hyperscaler-like experience for your customers

Managed Kubernetes running reliably and scaling as needed
Automate tenant and infra provisioning
Deep integrations into your network and infra layer

Launch managed K8s fast

Trusted by the fastest-growing AI cloud providers

Give every AI team the GPU access they need, without multiplying your infrastructure

Isolated Kubernetes environments per team, project, or training run
Cloud-like self-service for ML engineers without new cluster overhead
Maximize utilization with automatic allocation of nodes to tenants based on capacity needs

Operate your GPUs like a hyperscaler

Reference Architecture: vCluster on NVIDIA DGX

“With vCluster on DGX systems, you can bring the elasticity, automation, and multi-tenancy of Kubernetes onto your on-prem infrastructure. Get the experience of the public cloud on your DGX systems.”

Provision Kubernetes across any public or private cloud, and shift workloads freely

One platform to manage tenants across EKS, GKE, AKS, and private cloud
Consistent developer experience regardless of the underlying infrastructure
Shift workloads between environments without re-architecting

Lightweight · Isolated · Fast

Virtual clusters, real isolation.

Choose the control plane deployment model that fits your infrastructure.

Control Planes as Pods

Deploy vCluster Standalone on a few bare metal CPU machines as your Control Plane Cluster

Faster spin up time
Less resources needed
Manage tenant control planes the Kubernetes-native way

Control Planes on VMs

Connect any VM provisioning tool to vCluster Platform or let vCluster Platform spin up a KubeVirt cluster

OS-level separation between every tenant
Built for strict compliance requirements
Works with KubeVirt or any VM provisioner

Choose the workload isolation model that matches your security and cost requirements.

Private Nodes

Reserve physical nodes, including GPUs, exclusively per tenant

Dedicated nodes with no hardware sharing between tenants
Full GPU memory isolation, no noisy-neighbor interference
Meets the strictest compliance and data residency requirements

Shared Nodes

Run tenant workloads on shared infra with namespace-level guardrails

Maximum tenant density on shared infrastructure
Namespace isolation with network policies and resource quotas
Lower cost per tenant

Harden control plane pods and workloads

Combine with vNode for runtime-level isolation — or pair with gVisor or Kata Containers.  Blocks container escapes and kernel exploits at the node level.

Why vCluster

You think you can DIY this?

This isn’t a side project. Behind every vCluster deployment is 5+ years of deep K8s engineering, security hardening, and battle-tested infrastructure work at massive scale.

100K+

GPU Nodes Powered

Plus 1M+ CPU nodes in production and growing

50+

GPU Clouds & Fortune 500s

Battle tested at massive scale across enterprise and hyperscaler environments

30M+

Lines of Code

Continuously growing as new chip generations and K8s versions ship

30+

Hardcore K8s Engineers

5+ years of deep infrastructure and distributed systems engineering

Highly Resilient Cluster Operations

Control planes that auto-heal and self-scale. Tenant disruptions can’t take your platform down.

Reliable Technology Proven at Scale

Runs millions of production clusters across every major cloud and bare metal environment.

Enterprise-Grade High-Security Clusters

Hardened by default: tenant isolation, RBAC, and network policies built in from day one.

Security Audited by Industry Leading Pentesters

Including containerd and Linux kernel-level attack surfaces. Most platforms never go this deep.

Best-In-Class 24/7 Support

Deep infra and Kubernetes experts on call. Not a generalist tier-1 help desk.

Open Source Core, Millions of Users

Production-tested by thousands of teams worldwide and backed by a massive open source community.

Certified Kubernetes Distro

Officially CNCF certified. Build on standards, not proprietary lock-in.

Continuously Improving Platform

New features, chip generation support, and K8s version compatibility shipped continuously, not quarterly.

The best in the industry trust vCluster.

GET STARTED

Deploy vCluster in minutes.

With a few simple commands, you can create your first virtual cluster and define how workloads are isolated — all with a lightweight vcluster.yaml config.

Virtual clusters run on fully separate nodes with their own CNI, CSI, and control

# vcluster.yaml
privateNodes:
  enabled: true
controlPlane:
  service:
    spec:
      # could also be LoadBalancer if available
      type: NodePort

Virtual clusters share the host’s nodes and plugins

# vcluster.yaml
sync:
  fromHost:
    nodes:
      # set to true for real node specs
      enabled: false

Deploy on...
