vCluster is an open-source project, licensed under Apache 2.0, that creates virtual Kubernetes clusters running inside an existing host cluster. Platform teams use it to give tenants their own isolated control planes without provisioning separate physical clusters. The vendor also offers commercial products built around the core, including services for managing AI and GPU infrastructure. The open-source core is installed and operated by the customer in its own Kubernetes environments.
The company behind vCluster is based in the United States. Its legal name and ownership are not set out on the vendor's website, so no foreign parent is identified. Because the core runs inside clusters the customer controls, the processing of workload data stays with the operator. Where a vendor-hosted offering is used, its hosting location and data processing terms should be checked before a European organisation relies on it.
