Kubernetes. Better.

The leading multitenancy solution for secure, efficient, portable AI & CPU Infrastructure.

Virtual clusters, real isolation.

Each virtual cluster has its own API server, runs on shared or dedicated infrastructure, and gives you flexible tenancy options — from simple namespaces to fully dedicated clusters and everything in between.

Virtual clusters share the host’s nodes and plugins

# vcluster.yaml
sync:
  fromHost:
    nodes:
      # set to true for real node specs
      enabled: false

Virtual clusters run on their own set of host-assigned nodes but share the host’s plugins

# vcluster.yaml
sync:
  fromHost:
    nodes:
      # set to false to show pseudo nodes
      enabled: true
      selector:
        labels:
          tenant: tenant-1

Virtual clusters run on fully separate nodes with their own CNI, CSI, and control

# vcluster.yaml
privateNodes:
  enabled: true
controlPlane:
  service:
    spec:
      # could also be LoadBalancer if available
      type: NodePort

“Cutting costs by migrating individual clusters to vClusters feels great.”

Dan Garfield
Co-Founder

“Any organization that runs a lot of clusters should seriously look at vCluster. With vCluster you can bring down the cost and increase agility and security.”
