Towards Sustainable Multi-Cluster Management in Real-World Academic Infrastructure - J. Mok & C. Im

This KubeCon talk explores real-world multi-cluster management in an academic research environment with 4 bare-metal clusters, 2PB Rook-Ceph storage, and mixed GPU infrastructure. The speakers share practical lessons on extracting management clusters via vcluster while maintaining tenant workloads, and implementing Kyverno-based security with PSS Restricted and NetworkPolicies for tenant isolation. Ideal for platform engineers managing production Kubernetes clusters who want to learn from real migration failures and trade-offs.
