Internal Kubernetes Platform
Give Every Tenant a Cluster. Own the Platform.
vCluster lets platform engineers hand out self-service Kubernetes environments to every tenant, with the isolation, governance, and cloud portability to run anywhere.
The Problem
What’s Holding Back Kubernetes Adoption Across Your Org
Platform teams face an impossible choice: lock things down and lose developer velocity, or open things up and lose control.
WITHOUT VCLUSTER
Platform Team
as Bottleneck
- Dedicated cluster per team: Hours to provision, massive cost and sprawl
- Shared namespaces: CRD conflicts, blast radius risk, no real isolation
- Manual provisioning: Developers wait days, platform engineers drown in tickets
- No cloud portability: Inconsistent environments across EKS, AKS, GKE, on-prem
- Governance gaps: No way to enforce limits, policies, or cost attribution at scale
Kubernetes adoption stalls. Developers are frustrated. The platform team can’t scale.
WITH VCLUSTER
Self-Service With Platform-Grade Control
- Self-service tenant clusters spin up in under 3 seconds
- Each tenant gets an isolated control plane: no noisy neighbors, no blast radius
- Platform teams set guardrails once; governance is applied at creation time
- One consistent platform layer from EKS to GKE to bare metal to on-prem
- 80%+ reduction in Kubernetes spend through cluster consolidation
Platform engineers own the infrastructure. Every team owns their environment.
How It Works
One Infrastructure, Infinite Environments
vCluster runs isolated virtual control planes inside your existing shared clusters. Every tenant gets a full Kubernetes experience without dedicating physical infrastructure to each one.
STEP 1
Tenant requests an environment
Self-service portal
STEP 2
Template enforces policy & guardrails
RBAC · Quotas · Network
STEP 3
vCluster provisions isolated control plane
~30 seconds
STEP 4
Tenant gets a full Kubernetes cluster
API server · etcd · RBAC
Dedicated Control Planes
Each tenant gets its own API server, etcd, RBAC, and CRD scope. No noisy neighbors, no blast radius, no CRD conflicts.
Self-Service, Platform-Governed
Any tenant gets Kubernetes on demand from a portal, CLI, or GitOps workflow. Policies, RBAC, and resource quotas are enforced automatically at provisioning.
Any Cloud or On-Prem
Deploy identically on EKS, AKS, GKE, bare metal, or on-prem. The same platform layer everywhere, with no environment drift.
Private Nodes
Compliance, GPU, or high-security workloads get dedicated compute with zero cross-tenant exposure.

Auto Nodes
Nodes provision on demand and scale down when workloads finish. No idle waste, no manual capacity planning.

Cost Control at Scale
Consolidate hundreds of clusters into a few shared ones. Auto Sleep keeps every idle environment at zero cost automatically.

The Full Tenancy Spectrum
vCluster spans every isolation model, from shared namespaces to fully dedicatedsingle-tenant clusters, giving platform teams the flexibility to match each workload’s needs.

Key Features
The Platform Features Teams Depend On
The capabilities platform engineers reach for first when designing a secure, scalable internal Kubernetes platform.
Flexible Tenancy Models
Choose the right isolation for every workload
Shared nodes, dedicated nodes, or private nodes per tenant. Match isolation level to security, compliance, and cost requirements without changing how tenants interact with Kubernetes.
Read the guide
SSO & RBAC
Connect to your identity provider
Integrate with Okta, Azure AD, or any OIDC provider. Role bindings map to your org’s groups automatically.
Read the docs
Templates
Codify your standards once, deliver them at scale
Define approved cluster blueprints once. Every environment provisioned from a template inherits resource limits, policies, and labels automatically.
Read the docs
Auto Sleep
Idle clusters cost nothing
Idle environments scale to zero and wake in seconds. One Fortune 500 customer saved $6M+ annually across 200+ pre-prod clusters.

CRD Sync
Platform resources in every tenant
Sync CRDs and custom resources from the host into every tenant vCluster. Certificates, secrets, and platform objects available without manual bootstrapping.
Read the docs
Shared Platform Stack
Run shared services once, available to all
Cert-manager, ingress controllers, monitoring, and service mesh run on the host and are shared across tenants. No duplication, no drift, one platform team manages it all.

Use Cases
Every Tenant That’s Been Waiting for a Cluster
Platform engineers use vCluster to serve a wide range of tenants: dev teams, CI pipelines, ML workloads, compliance environments, and more.
Use Case 01
Dev Environments Without the Wait
Isolated dev environments in seconds. Full admin access and production-like configs, no ticket required.
Use Case 02
CI / CD Pipeline Isolation
Every pipeline run gets its own ephemeral cluster. Parallel, isolated, auto-deleted on completion.
Use Case 03
Preview Environments per PR
A clean environment per feature branch. Reviewers test real infrastructure, not mocks. Auto-deleted after merge.
Use Case 04
Production Parity Testing
Replicate production configs, RBAC, and policies exactly. Catch drift and integration issues before they reach prod.
Use Case 05
Security and Policy Validation
Test OPA, Kyverno, and NetworkPolicies in isolated clusters before rollout. Validate enforcement without touching live environments.
Use Case 06
Demo and Training Environments
Clean, reproducible environments for demos, onboarding, and labs. Self- service, isolated per session, auto-deleted when finished.
Customer Stories
Trusted by Platform Teams Worldwide
“Many of our developers are not really familiar with Kubernetes. Our challenge was to enable these developers to test their microservices against the rest of Ada’s software stack without needing to know how Kubernetes really works.”
