Object storage is ideal for static files, media, and archival data. Use S3-compatible APIs for portability. Set lifecycle rules for tiering and deletion. Combine with CDN for fast delivery of assets.
Static assets and media
- Static files: CSS, JS, images, fonts. Serve from object storage; app or CDN reads via HTTP/S3. Reduces load on app servers; scales with traffic. Use versioned or hashed keys for cache busting.
- Media: User uploads, videos, images. Store in buckets; generate thumbnails or transcodes (via workers); serve through CDN. Set appropriate content-type and cache headers.
- Portability: S3-compatible API (AWS S3, MinIO, DigitalOcean Spaces, etc.) lets you switch providers or run on-prem without rewriting app code. Use SDK or REST; avoid provider-specific features if you want to stay portable.
Lifecycle and tiering
- Lifecycle rules: Automate transition to cheaper storage classes (e.g. Infrequent Access, Glacier) after N days. Automate deletion (e.g. temp uploads after 7 days). Reduces cost for large volumes.
- Versioning: Enable versioning on critical buckets so you can recover from accidental overwrite or delete. Combine with lifecycle to expire old versions after a period.
- Tiering: Hot data in standard class; cold or archive in IA/Glacier. Match retention and access patterns to cost.
Logs and data lakes
- Logs: Ship application or server logs to object storage (e.g. daily or streaming). Cheap, durable; query with Athena, BigQuery, or similar. Retain per compliance; delete when no longer needed (lifecycle).
- Data lakes: Raw or processed data in object storage; query with engine on top (Spark, Presto, etc.). Separation of storage and compute; scale independently. Use partitioning (prefixes/key design) for efficient query.
CDN and delivery
- CDN: Put a CDN (CloudFront, Cloudflare, etc.) in front of the bucket origin. Cache at edge; reduce latency and cost for read-heavy assets. Invalidate or use versioned URLs when you update content.
- Access control: Bucket policies and signed URLs for private content. Do not expose bucket publicly unless intended; use CDN or app to gate access.
Summary
Object storage is ideal for static files, media, and archival data. Use S3-compatible APIs for portability. Set lifecycle rules for tiering and deletion. Combine with CDN for fast delivery. Use for logs and data lakes with appropriate query engines.
