Multitenancy in Kubernetes

Solutions

Multi-tenancy is a Kubernetes cluster model or architecture model in which a single cluster’s resources are shared among multiple tenants. Examples of the shared cluster resources include CPU, memory, networking, and control plane resources. (ContainIQ)

VirtualCLuster

VirtualCluster represents a new architecture to address various Kubernetes control plane isolation challenges. It extends existing namespace based Kubernetes multi-tenancy model by providing each tenant a cluster view. VirtualCluster completely leverages Kubernetes extendability and preserves full API compatibility. That being said, the core Kubernetes components are not modified in virtual cluster.
