Longhorn vs Rook-Ceph: Kubernetes Storage Compared
Every Kubernetes cluster eventually needs persistent storage. The question is: which solution? For self-hosted clusters without cloud provider storage classes, two options dominate: Longhorn and Rook-Ceph. Both are CNCF projects. Both provide replicated block storage. Both work well. But they’re very different in philosophy, complexity, and use cases. I’ve run both in production. Let me share what I’ve learned. The Fundamental Difference Longhorn: Simple distributed block storage built for Kubernetes. Each volume is replicated across nodes using standard Linux storage primitives. ...
