Design the storage architecture for a containerized stateful service (e.g., a database cluster) running on Kubernetes.
Cover: StatefulSet usage for stable network identities and ordered, predictable pod management; PersistentVolumeClaims backed by a storage class appropriate to the performance/durability needs (e.g., provisioned IOPS for a database workload); a clustering/replication strategy native to the database itself (most databases shouldn't rely solely on Kubernetes-level mechanisms for data replication); pod anti-affinity rules ensuring replicas land on different physical nodes/zones; and a backup/restore strategy integrated with the storage layer (volume snapshots) in addition to logical (e.g., pg_dum
