What is STACKIT Object Storage?

STACKIT Object Storage is a scalable, S3-compatible object store for unstructured data. Objects are stored with unique identifiers and customizable metadata in a flat structure, ideal for large volumes of unstructured data. Buckets are region-specific and distribute data across all availability zones of that region. STACKIT operates the service from data centers in Germany (EU01) and Austria (EU02).

Core Features

  • S3 compatibility: Use with common S3 clients, SDKs, and tools without code changes
  • Multi-AZ distribution: Data is automatically distributed across all availability zones of a region
  • Encryption: AES-256 encryption at rest by default, with optional customer-provided keys (SSE-C); TLS 1.3 for all endpoints
  • Standard and archive tiers: Separate archiving tier for infrequently accessed data at lower cost
  • Flexible use: Suited for backups, media, data lakes, and static hosting

Typical Use Cases

Backup and disaster recovery: Regular backups are stored cost-effectively and redundantly across multiple availability zones.

Media and content distribution: Images, videos, and other media can be served directly from Object Storage.

Data lakes and analytics: Large volumes of unstructured data for analytics processes and machine learning pipelines.

Long-term archiving: The archiving tier suits compliance-relevant data that is accessed infrequently.

Benefits

  • Data sovereignty: Operated from German/Austrian data centers
  • GDPR-compliant: No risk from US-CLOUD Act access
  • S3 tools work: Existing S3 SDKs and applications work with minimal adjustments
  • Cost-effective: Separate archive tier for infrequently used data
