In the session, Rich Burroughs and Carl Montanari discuss virtual Kubernetes clusters, emphasizing their benefits, functionality, and versatility. The talk highlighted the two dominant Kubernetes multi-tenancy models: namespace-based and cluster-based isolation. We are then introduced to the concept of "vcluster," which operates within a namespace on a host cluster. The session delved deep into how vclusters function, their architecture, syncing processes, and interactive capabilities. Towards the end, the speakers unveiled that the entire demonstration was conducted within a vcluster, showcasing its robustness.
