Overview
Longhorn provides persistent block storage volumes for Kubernetes workloads with built-in snapshotting, backup, and disaster recovery, aiming for a much simpler operational footprint than Ceph while still being distributed and highly available. It's a CNCF graduated project popular in edge and homelab Kubernetes deployments as well as production clusters.
Longhorn is a fit for teams that want distributed block storage for Kubernetes without Ceph's operational complexity, a lighter-weight alternative to Rook and Ceph already in this catalog for teams that don't need Ceph's full feature set.
