Kubernetes Persistent Data Challenges – AZ, Region and Multi-Clou...

" summary

Demo runs on EKS with i3en NVMe nodes and a StorageOS CSI plugin backing Prometheus and Cassandra via the k8ssandra operator; cordon/drain and a terminated instance both show Prometheus keeps historical metrics because of storage-layer replication while Cassandra continues serving thanks to its app-level replication and the cluster auto-replaces the node. Multi-cluster prototype uses Aviatrix networking, k8ssandra control/data-plane pairing and gossip across GKE/AKS/EKS; networking, cross-cloud credentials, latency and egress costs are the real obstacles.
