An object storage service

• To store and serve large amounts of unstructured data (with large size), like media files, backups, and static assets.
• Not like db, not for relational data.

Features:

• S3 Compatibility
  • R2 supports S3 API, making it easy to integrate with existing tools and applications.
• No Egress Fees
  • Doesn’t charge for data egress, making it cost-effective for serving content.
• Global Distribution
  • R2 stores data regionally
  • Cloudflare serves it globally via its network
  • When combined with CDN / Workers, it feels globally distributed
• Integrated with Cloudflare Workers
  • like lambda, but ultra-light serverless at edge
  • Workers can read/write R2 objects and act as a secure access layer.
  • More dynamic and efficient workflows.

Workers

• inside Cloudflare data centers
• very fast
• limited runtime
• no JVM (JS / TS / WASM only)
