Bare metal is finally viable—no more expensive, wasteful VMs. Virtual clusters and virtual nodes give you isolation without the overhead.
That defeats the purpose of Kubernetes. We’ve just replaced pet VMs with pet clusters—each with 3 to 5 VMs—adding cost and complexity. Kubernetes was built for large shared clusters, but instead of solving for multi-tenancy, we spun up thousands of tiny ones. That’s the problem we set out to solve— making it finally viable to run Kubernetes on bare metal, without sacrificing isolation.”
One big Kubernetes cluster per data center should be enough—but sharing is hard. That’s why teams spin up tiny clusters made up of VMs, wasting compute capacity and money. Now you can share one big cluster, no VMs required.
vCluster gives each team a fully isolated control plane without needing a separate cluster.
vNode keeps workloads securely isolated on shared physical nodes—no hypervisor needed.
“vCluster enabled us to consolidate our Kubernetes infrastructure from nearly 200 VMs down to a single bare-metal cluster, cutting private cloud costs while improving performance and efficiency.”
“We run 8,000 VMs just to host containerized workloads we already trust.” – Global Platform Lead, Fortune 100 Financial Institution
VM sprawl
Each cluster runs on its own VMs, multiplying cost and complexity
Low utilization
Most VM-backed clusters use less than 20% of CPU and memory.
License shock
VMware costs ~$4k per CPU core—and grows with every cluster.
Slow delivery
Separate VM and Kubernetes teams add friction and risk.
Add a security envelope around every tenant workload so you can safely and dynamically share the same physical nodes.
Higher utilization: Confidently pack nodes and reach 70%+ usage.
GPU ready: No hypervisor means fast, direct access for AI/ML.
Zero VM fees: Get isolation and efficiency without the VMware tax.
Virtual nodes, not VMs: isolation via namespaces and seccomp.
Secure by design: Containers stay sandboxed—no breakouts.
Dynamic sharing: No static VM boundaries—resources stay flexible.
