VIRTUAL NODES

Stronger Multi-Tenancy for Kubernetes with
Node-Level Isolation

vNode isolates workloads into virtual nodes, providing stronger isolation and tenant autonomy — without the cost of provisioning additional nodes or compromising performance.

Better isolation. Less overhead.

What are virtual nodes?

Virtual nodes in Kubernetes enhance multi-tenancy by creating isolated environments within a shared physical node. They provide tenant-level isolation, ensuring security and autonomy without the overhead of separate physical nodes.

Why Teams Love Vnode

Isolation. Autonomy. Efficiency.

Protect workloads and enforce strict multi-tenancy

Stronger Isolation – Keep workloads truly separate. Virtual nodes prevent noisy neighbor issues and cross-tenant interference at the node level.

Enterprise-Grade Security – Lock down multi-tenancy. Minimize shared kernel risks and meet compliance needs with strict workload isolation.

Empower teams with flexibility and autonomy

Better Tenant Autonomy – Give tenants real control. Run privileged workloads securely—without the limits of traditional shared Kubernetes environments.

Seamless Kubernetes Integration – Works anywhere, no re-architecture needed. vNode supports containerd-based Kubernetes environments on any Linux node (v1.6+), across public and private clouds, with full CPU and GPU support.

Optimize for speed, efficiency, and cost savings

Performance & Efficiency – Run fast, stay light. Get near-native performance with minimal overhead—without the cost and overhead of VMs.

Cost-Effective – More security, less spend. Gain node-level isolation without the high cost of separate physical nodes.

How vNode Works

Deploy. Isolate. Secure.

1

Deploys a Lightweight Runtime – Install the vnode-runtime Helm chart to launch the vNode Runtime DaemonSet, which automatically manages virtual nodes on each physical node.

2

Creates Isolated Virtual Nodes – Each physical node runs the vNode Manager Pod and other core components to create secure, tenant-specific virtual nodes.

3

Runs Workloads in Secure Environments – Each vNode Manager operates with its own vnode-init, vnode-runc, and vnode-containerd-shim—ensuring complete isolation for workloads inside a shared Kubernetes cluster.

Lock It Down. Run It Fast. Move On.
