BUILT FOR PLATFORM ENGINEERS

Safely Build and Test Kubernetes Controllers and APIs

Give every engineer their own control plane. With vCluster, platform teams can isolate testing of operators, CRDs, and APIs, without breaking the shared cluster.

Why Shared Clusters Break at Scale

When dozens of engineers share the same Kubernetes cluster for control plane development, conflicts are inevitable. One test can crash it for everyone.

Challenge

50 Engineers Sharing One EKS Cluster= Constant Collisions

A global financial firm had 50+ platform engineers sharing one EKS cluster. It worked, until it didn’t.

  • Webhooks and controllers clash and crash
  • CRDs change and cause drift across teams
  • RBAC misconfigurations create security risks
  • Slowdowns and instability for everyone
Solution

50 Isolated Control Planes On One EKS Cluster= Zero Disruption

With vCluster, each engineer now spins up their own Kubernetes API server, no stepping on toes, no wasted time.

  • Test webhooks and controllers in full isolation
  • Eliminate CRD conflicts and version drift
  • Safely experiment with RBAC and API changes
  • Move faster without fear of breaking shared infra

vCluster: Test Kubernetes Extensions in Isolation

Faster Feedback Loops

Eliminate cluster provisioning delays

Supports All K8s Extensions

Webhooks, CRDs, operators, etc.

CI/CD Friendly

Automate everything via API or CLI

Tenancy That Grows With You

Start with lightweight virtual clusters on shared nodes. As your needs evolve, vCluster supports advanced models like dedicated or private nodes, without changing your workflows.

  • Shared Nodes
    Tenants share nodes dynamically within a single cluster, with isolation enforced at the node level using vNode. Shared services like CNI and CSI remain in place and require policies for secure multi-tenancy.
  • Dedicated Nodes
    Each tenant is assigned dedicated nodes using Kubernetes Node Selector, making it easy to isolate workloads while still allowing flexible reassignment. Shared services such as CNI and CSI require additional policy controls for full isolation.
  • Private Nodes
    Tenants get a fully isolated virtual cluster backed by private nodes, effectively forming their own separate cluster. This includes isolated control planes, networking (CNI), storage (CSI), and all node-level components, delivering complete workload and infrastructure separation.

Built for Enterprise-Scale Platform Teams

Whether you’re building a self-service platform or managing hundreds of engineers, vCluster provides the flexibility, control, and isolation you need, without adding operational overhead.
