What is STACKIT File Storage?
STACKIT File Storage is a fully managed shared storage service that provides NFS-based file systems for concurrent access by multiple VMs and containers. Unlike Block Storage, File Storage enables parallel read and write access from up to 1,000+ clients. As a German cloud provider, STACKIT hosts all data in German data centers, ensuring full GDPR compliance.
Core Features
- Multi-Client Access: Up to 1,000+ simultaneous NFS connections
- NFS Protocols: Support for NFSv3 and NFSv4.1 with POSIX semantics
- Scalable Performance: Standard tier for general workloads, Premium tier for up to 100,000 IOPS
- Snapshots: Point-in-time backups for data recovery
- Kubernetes Integration: CSI driver for automatic PersistentVolume provisioning
Typical Use Cases
Content Management Systems: CMS platforms with multiple web servers using shared access to media assets and uploads. New instances can scale automatically during traffic spikes.
Kubernetes Persistent Volumes: StatefulSets and Deployments with ReadWriteMany access mode. Multiple pods access the same data simultaneously, e.g., for static assets.
Media Rendering: Video rendering and 3D modeling with parallel access to large datasets. Premium tier delivers the necessary IOPS for frame-by-frame processing.
Benefits
- GDPR-compliant: All data in German data centers
- Independent Scaling: Capacity and performance scalable separately
- End-to-End Encryption: AES-256 at rest, TLS in transit
- Kubernetes-native: CSI driver for automatic lifecycle management
