Neocloud Tenant Isolation at Bare Metal Speed

Stop choosing between tenant isolation and performance. vCluster creates fully isolated Kubernetes clusters on bare metal, giving every neocloud tenant their own API server, etcd, and RBAC without provisioning separate physical clusters.

Problem

The Neocloud Infrastructure Trap

AI cloud providers face three compounding problems that delay revenue and erode margins.

Raw Compute Is Not Enough

Selling bare metal GPUs alone is a race to the bottom. Customers want the cloud experience, not just raw specs.

DIY Platform Takes Years

Building a GPU cloud platform yourself takes 6 to 10 engineers, 6 to 12 months, and over a million dollars.

Isolation vs. Efficiency Tradeoff

Namespace isolation is too weak. Separate physical clusters are too expensive. Standard Kubernetes forces you to choose.

Solution

One Stack from Bare Metal to Tenant Clusters

vCluster delivers the complete infrastructure path for neocloud providers: zero-touch bare metal provisioning with vMetal, fully isolated CNCF-certified tenant clusters via vCluster, and kernel-native workload isolation through vNode. Proven across 100K+ GPU nodes and 50+ GPU clouds including CoreWeave and Nscale.

Built for AI Cloud Providers at Scale

Every layer of the stack purpose-built for GPU cloud operators who need tenant isolation without sacrificing bare metal performance.

Tenant Isolation

Isolated Tenant Clusters in Seconds

Each tenant gets a fully isolated Kubernetes control plane running as a lightweight pod. Own API server, etcd, scheduler, and RBAC with no physical cluster provisioning required.

  • Spins up in seconds
  • Full cluster-admin per tenant
  • CNCF-certified K8s per tenant
Bare Metal

Zero-Touch GPU Server Provisioning

PXE boot, OS installation, machine registration, and network automation handled automatically. Take GPU racks from delivery to production-ready Kubernetes without manual intervention.

  • PXE boot to production-ready
  • Full machine lifecycle management
  • No manual OS configuration
Workload Security

Kernel-Native Isolation Without VM Overhead

vNode (currently in private beta) wraps every workload in its own secure runtime using seccomp, cgroups, namespaces, and AppArmor. Container breakout protection without hypervisor tax on GPU performance.

  • No hypervisor performance penalty
  • Container breakout protection
  • Compatible with gVisor and Kata
Dynamic Scaling

Automatic GPU Node Provisioning

When tenants schedule workloads, bare metal GPU nodes are provisioned automatically via Terraform. Scale physical infrastructure on demand without manual datacenter operations.

  • Terraform-driven node provisioning
  • Scales on tenant workload demand
  • Eliminates idle GPU overhead
Tenant Experience

EKS-Like Portal for Your Customers

Give your neocloud customers a self-service portal to provision and manage their own Kubernetes environments. Deliver the cloud experience AI teams expect from hyperscalers, on your infrastructure.

  • Self-service cluster provisioning
  • EKS-like tenant experience
  • No platform engineering per request

Why vCluster

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.

FAQs

What is a neocloud and how does vCluster support it?

A neocloud is an AI cloud provider offering GPU compute as a service, typically built on bare metal infrastructure rather than legacy virtualization. vCluster supports neoclouds by delivering the full infrastructure stack from bare metal provisioning to isolated tenant Kubernetes clusters to kernel-native workload isolation. Providers like CoreWeave and Nscale use this stack to offer managed Kubernetes environments on top of their GPU hardware without the cost or complexity of provisioning separate physical clusters per customer.

How does vCluster deliver tenant isolation without separate physical clusters?

vCluster virtualizes the Kubernetes control plane itself. Each tenant receives a fully isolated cluster with its own API server, etcd, scheduler, and RBAC running as a lightweight pod inside the host cluster. This gives tenants genuine cluster-admin isolation without the cost of dedicated physical clusters. The isolation spectrum ranges from shared nodes with namespace boundaries through to private dedicated nodes with hardware-level separation, so operators can match isolation strength to tenant requirements.

How long does it take to launch a managed Kubernetes offering on GPU hardware?

Boost Run launched their managed Kubernetes service in less than 45 days using vCluster with zero new platform engineering hires. Lintasarta launched Indonesia's leading GPU cloud in 90 days, deploying 170+ tenant clusters on their infrastructure. The speed advantage comes from vCluster replacing years of custom platform engineering with a production-proven stack that covers bare metal provisioning, tenant cluster orchestration, and Day 2 operations out of the box.

Does vCluster require an existing Kubernetes cluster to run on bare metal?

No. vCluster Standalone runs as a single binary directly on Linux bare metal with no external Kubernetes dependency. There is no need for k3s, kubeadm, or k0s as a base layer. This means GPU cloud providers can go from raw hardware to a running Kubernetes distribution to isolated tenant clusters in one integrated path, without stitching together multiple open-source tools.

How does vNode protect GPU cloud tenants from container breakouts?

vNode (currently in private beta) provides kernel-native workload isolation using seccomp, cgroups, Linux namespaces, and AppArmor at the individual workload level. It significantly limits container escape from reaching the host kernel or neighboring tenant workloads. Unlike VM-based isolation, vNode adds no hypervisor overhead, preserving bare metal GPU performance. It is compatible with gVisor and Kata Containers for operators who need additional defense-in-depth layers, and it complements vCluster's control plane isolation.

Is vCluster recognized in any industry standards for GPU cloud security?

Yes. vCluster is named in the NVIDIA DGX SuperPOD reference architecture and is cited in the SemiAnalysis ClusterMax evaluation criteria as a requirement for GPU cloud providers. The platform powers 100K+ GPU nodes in production across 50+ GPU clouds and Fortune 500 customers. The CNCF-certified Kubernetes distribution ensures each tenant cluster meets full API conformance standards without proprietary lock-in.
