GPU as a Service Built on Tenant Isolation

Launch a competitive GPU as a service offering in weeks. vCluster Platform deploys hundreds of fully isolated, CNCF-certified tenant clusters on shared bare metal with near-zero marginal cost per tenant.

Problem

Why GPU as a Service Is Hard to Launch

GPU providers stall competing on specs alone while customers demand cloud-grade managed Kubernetes experiences.

Raw Compute Is Not Enough

Customers don't just want raw compute. They expect self-service environments, managed Kubernetes, and cloud-native tooling from day one.

Namespace Isolation Is Too Weak

Namespace isolation leaves tenants exposed to platform internals and each other. Separate physical clusters are too expensive to scale.

Building In-House Takes Years

Based on industry experience, building a GPU cloud platform typically requires 6 to 10 engineers, 6 to 12 months, and over a million dollars. Most teams we've spoken with are still building two years in.

Solution

One Stack From Bare Metal to Tenant Clusters

vCluster Platform virtualizes the Kubernetes control plane itself, giving every tenant their own API server, etcd, RBAC, and CRDs as lightweight pods on shared bare metal. Boost Run launched a GPU as a service offering in less than 45 days. Lintasarta launched Indonesia's leading GPU cloud in 90 days with 170+ tenant clusters.

Everything to Launch Your GPU Cloud

From zero-touch bare metal provisioning to isolated tenant clusters and pre-validated AI environments, vCluster covers the full stack.

Bare Metal

Zero-Touch GPU Server Provisioning

PXE boot, OS installation, machine registration, and network automation handled automatically. Go from GPU rack to production-ready infrastructure without manual intervention at every step.

  • PXE boot to production automatically
  • Full machine lifecycle management
  • Network automation built in
Tenant Isolation

Isolated Tenant Clusters in Seconds

Every tenant gets a fully isolated Kubernetes control plane running as a lightweight pod. Own API server, etcd, scheduler, and RBAC on shared bare metal hardware with no physical cluster per tenant.

  • Spin up tenant clusters in seconds
  • Own API server per tenant
  • Hundreds of tenants on shared hardware
Workload Security

Kernel-Native Workload Isolation

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

  • No hypervisor tax on GPU performance
  • Container breakout protection
  • Defense-in-depth isolation stack
AI Environments

Pre-Validated AI Platforms Included

Pre-validated environments for Run:AI, Ray, and Jupyter turn a bare Kubernetes cluster into a production AI platform in minutes. Skip weeks of integration work and deliver managed AI tooling from launch.

  • Run:AI, Ray, Jupyter ready instantly
  • Cluster to AI platform in minutes
  • Certified against tenant isolation
Customer Experience

EKS-Grade Self-Service for Customers

Give end customers an EKS-like self-service portal to provision their own isolated environments on demand. Your GPU as a service offering matches the cloud experience AI teams already expect.

  • Self-service cluster provisioning portal
  • EKS-like customer experience
  • Fully branded tenant environments

FAQs

What is GPU as a service and how does Kubernetes fit in?

GPU as a service means providing customers on-demand access to GPU compute with cloud-grade management on top. Kubernetes has become the standard orchestration layer for AI workloads, so GPU cloud providers are expected to offer managed Kubernetes alongside raw compute. vCluster Platform lets you deliver fully isolated, CNCF-certified tenant clusters on your bare metal GPU infrastructure so every customer gets the cloud experience they expect without you provisioning a separate physical cluster per tenant.

How fast can I launch a GPU as a service offering with vCluster?

Boost Run launched their managed Kubernetes service in less than 45 days using vCluster Platform. Lintasarta launched Indonesia's leading GPU cloud in 90 days with 170+ tenant clusters. The platform handles bare metal provisioning, tenant cluster orchestration, and workload isolation in one integrated stack, so your engineering team focuses on differentiation rather than rebuilding infrastructure primitives from scratch.

How does vCluster isolate tenants on shared bare metal GPU hardware?

Each tenant receives a fully isolated Kubernetes control plane running as a lightweight pod with its own API server, etcd, RBAC, and CRDs. On the workload side, vNode (currently in private beta) adds kernel-native isolation using seccomp, cgroups, namespaces, and AppArmor to prevent container breakouts without adding hypervisor overhead. This means you get strong tenant isolation across the full stack while preserving bare metal GPU performance.

Does vCluster support dedicated GPU nodes per tenant?

Yes. vCluster Platform offers a flexible isolation spectrum ranging from shared nodes to private nodes with fully dedicated physical hardware per tenant. Private nodes give each tenant their own CNI and CSI with no workload overlap from other tenants, making it suitable for GPU customers who require complete hardware isolation for performance or compliance reasons.

Is vCluster compatible with existing AI platforms like Run:AI or Ray?

Yes. Certified Stacks are pre-validated AI environments that include Run:AI, Ray, and Jupyter, turning a bare Kubernetes cluster into a production AI platform in minutes. These environments are tested and certified to work with vCluster tenant isolation, so AI platforms run in isolated tenant environments without requiring custom integration work from your team.

What bare metal GPU infrastructure does vCluster support?

vMetal handles zero-touch provisioning for GPU servers including PXE boot, OS installation, machine registration, and network automation. vCluster Standalone runs as a single binary directly on Linux with no dependency on k3s, kubeadm, or any external Kubernetes distribution as a base layer. vCluster is named in the NVIDIA DGX SuperPOD reference architecture and powers 100K+ GPU nodes across 50+ GPU clouds and Fortune 500 customers.
