Dedicated Kubernetes Environments for AI Clouds
Provision fully isolated, CNCF-certified tenant clusters on shared GPU hardware in seconds. vCluster delivers dedicated Kubernetes environments without the overhead of physical clusters.
Trusted by the fastest-growing AI cloud providers
Problem
Why Generic Isolation Falls Short
Standard Kubernetes forces a tradeoff between tenant isolation and operational efficiency.
Namespace Isolation Is Too Weak
Tenants can see platform internals they should not — cluster-wide agents, other tenants' nodes and running pods.
Separate Clusters Are Too Expensive
Provisioning physical clusters per tenant multiplies hardware cost and adds hours of spin-up time per environment.
DIY Takes Too Long to Build
Based on vCluster customer conversations, building dedicated Kubernetes environments in-house typically requires 6 to 10 engineers, 6 to 12 months, with total investment often exceeding a million dollars.
Solution
Dedicated Tenant Clusters Without Physical Overhead
vCluster virtualizes the Kubernetes control plane itself — giving every tenant their own API server, etcd, scheduler, and RBAC as a lightweight process. Dedicated Kubernetes environments spin up in seconds, proven across 100K+ GPU nodes and 50+ GPU clouds and Fortune 500 customers.
Built for Dedicated Kubernetes at GPU Scale
Every layer of the stack is designed to deliver strong tenant isolation and full Kubernetes compatibility without sacrificing performance.
Tenant Isolation
Dedicated Control Planes Per Tenant
Each tenant gets their own Kubernetes API server, etcd, and scheduler running as lightweight pods. Dedicated Kubernetes environments spin up in seconds with zero physical cluster provisioning.
- Own API server and etcd per tenant
- Spins up in seconds, not hours
- No physical cluster required
Node Isolation
Fully Dedicated Physical Nodes
Tenants receive fully dedicated physical nodes with their own CNI and CSI configuration. No workloads from other tenants share the same hardware, delivering complete node-level isolation.
- Dedicated hardware per tenant
- Own CNI and CSI per environment
- Zero workload cross-contamination
Standards Compliance
CNCF-Certified Kubernetes Per Tenant
Every dedicated Kubernetes environment is a fully conformant CNCF-certified cluster — 100% API compatibility. Tenants get a real Kubernetes cluster, not a proprietary or partial implementation.
- 100% Kubernetes API compatibility
- CNCF-certified distribution
- Works with all standard K8s tooling
Tenant Autonomy
Full Cluster Admin Per Tenant
Every tenant receives cluster-admin privileges within their dedicated environment. They can install CRDs, configure RBAC, and manage resources freely without impacting other tenants.
- Full CRD and RBAC control
- Tenant-scoped cluster-admin access
- No shared blast radius
Platform Operations
Central Fleet Management at Scale
Manage hundreds of dedicated Kubernetes environments from a single control plane. Unified UI, CLI, and API with SSO, quotas, templates, and auto-sleep across the entire tenant fleet.
- Unified UI, CLI, and API
- SSO, quotas, and templates built in
- Auto-sleep to reclaim idle resources
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
How are these Kubernetes environments truly dedicated if they share hardware?
vCluster virtualizes the Kubernetes control plane itself — each tenant gets their own real API server, etcd, scheduler, and RBAC running as isolated processes inside the host cluster. At the node level, Private Nodes give tenants fully dedicated physical hardware with their own CNI and CSI, meaning no other tenant's workloads run on the same machines. The result is a dedicated Kubernetes environment in every meaningful sense — isolated control plane, isolated data plane — without provisioning separate physical clusters.
Are the dedicated environments fully compatible with standard Kubernetes tooling?
Yes. Every tenant environment is a CNCF-certified Kubernetes cluster with 100% API compatibility. Tenants can use any standard Kubernetes tooling, install custom CRDs, configure RBAC, run Helm charts, and connect CI/CD pipelines exactly as they would with a standalone cluster. There is no proprietary API layer or partial Kubernetes implementation.
How quickly can a dedicated Kubernetes environment be provisioned?
Tenant clusters spin up in seconds because the control plane runs as lightweight pods inside the host cluster — no physical infrastructure provisioning required. This is fundamentally different from provisioning a new physical cluster, which can take minutes to hours. The speed enables self-service workflows where tenants provision their own dedicated environments on demand.
What isolation options are available for dedicated Kubernetes environments?
vCluster offers a flexible isolation spectrum. Shared Nodes provide namespace-level boundaries on shared hardware. Private Nodes give tenants fully dedicated physical nodes with their own networking stack. Dedicated VMs add OS-level isolation for the control plane. vNode (currently in private beta) adds kernel-native workload isolation using seccomp, cgroups, and AppArmor at the workload level — without VM overhead or hypervisor tax. Teams can match isolation depth to their specific compliance and performance requirements.
Can I manage hundreds of dedicated environments from a single platform?
Yes. The vCluster Platform includes a central fleet management layer with a unified UI, CLI, and API for managing all tenant clusters. Features like SSO, resource quotas, cluster templates, and auto-sleep work across the entire fleet. Boost Run launched a managed Kubernetes offering in less than 45 days, and Lintasarta launched Indonesia's leading GPU cloud in 90 days with 170+ tenant clusters under central management.
Does vCluster support air-gapped or compliance-restricted deployments?
Yes. vCluster supports air-gapped and FIPS-compliant deployment configurations for environments with strict connectivity and regulatory requirements. This makes dedicated Kubernetes environments viable for regulated industries, government workloads, and enterprises with data residency constraints. Deployment is possible in fully disconnected environments without relying on public registries or external dependencies.
