When the Red Light Goes On: How We Responded to the Linux Kernel 0-Day
On April 30, 2026, a 0-day in the Linux kernel was disclosed: root with a few lines of Python, and no updated kernel …
Virtual Kubernetes clusters as a certified Kubernetes distribution – with developer self-service, significantly lower infrastructure costs, and full tenant isolation. Our vClusters start at CHF 36.70 per month (in combination with an NKE node). A complete price list with additional options can be found in the Price Calculator and for more technical details, please check our Documentation.

Our vClusters give each team their own API server and dedicated control plane with RBAC (role-based access control), fully isolated yet running efficiently inside shared NKE infrastructure. Enable developer self-service so teams can spin up and tear down clusters on demand, while sleep mode and auto-delete reclaim unused resources automatically. The result: significantly lower infrastructure costs compared to dedicated clusters, without compromising on isolation or capabilities.
Much better isolated than namespaces
Cheaper than separate, 'real' Kubernetes clusters
More powerful thanks to its own API server
vCluster offer a unique developer experience for anyone developing against Kubernetes as a deployment target
When scalability limits of k8s are reached due to large multi-tenant clusters, clusters can be split into vClusters and effectively shared
New ingress controller tests can be virtually simulated without affecting cluster operation
Starting at CHF 36.70 per month (vCluster & nine-standard-1 Worker Node) and in combination with an NKE node, your vCluster is more powerful and better isolated than namespaces and cheaper than 'real' Kubernetes clusters
Virtual clusters are executed within the namespaces of other clusters. They have a separate API server and a separate data store so that every Kubernetes object created in the vCluster only exists within this vCluster. You can isolate workloads on bare metal Kubernetes, you don't need any VMs and you won't get Ops headaches or suffer from high costs anymore. Virtual clusters launch in seconds, offer better isolation for CPU and GPU workloads, and scale effortlessly. Virtual clusters allow you to create multiple isolated environments within a single cluster, minimizing the need to set up a separate cluster for each team, environment, or customer.
