Deep dives
Understanding vClusters
A virtual cluster (vCluster) operates within a traditional Kubernetes cluster, leveraging its underlying resources while providing isolated environments for different workloads. Unlike traditional clusters that are composed of dedicated machines, vClusters run as containers atop the host cluster, allowing for shared utilization of the underlying nodes. This architecture facilitates multi-tenancy, enabling different teams or clients to operate independently yet within the same physical infrastructure. The virtual cluster's design emphasizes the importance of providing users with a distinct and isolated control plane, ensuring secure and efficient resource management.
