Overview
Developed by Rancher Labs (now part of SUSE), Longhorn is designed to be lightweight, reliable, and easy to use. It provides highly available block storage by replicating data across multiple nodes in the Kubernetes cluster.
Key Features
- Enterprise-Grade Storage: Supports snapshots, backups, and cross-cluster disaster recovery.
- Incremental Backups: Efficiently backs up data to external object storage (S3/GCS).
- Easy Management: Includes a user-friendly dashboard for monitoring and managing volumes.
- Automatic Upgrades: Can upgrade the storage controller without interrupting the running workloads.
Use Case
Ideal for teams looking for a simple yet robust storage solution for stateful applications on Kubernetes, especially in smaller or edge clusters.
