Explore the challenges of multi-tenancy in Kubernetes and discover how the open-source project "vcluster" addresses them in this 26-minute CNCF conference talk. Dive deep into vcluster's architecture, understanding how it enables running multiple virtual Kubernetes clusters within a single K8s cluster, complete with a live demonstration. Learn about the limitations of traditional development environments using namespaces and clusters, and how vcluster provides greater flexibility and freedom for developers. Examine the control plane, network, and DNS configurations within vcluster, and compare it to namespace and cluster isolation. Investigate various use cases for vcluster implementation, and gain insights into available documentation and support resources.
