Cloudflare R2 + CDN Integration

I store a rapidly growing catalog of images and videos and need them delivered at lightning speed through Cloudflare’s infrastructure. The task is end-to-end: stand up a Cloudflare R2 bucket, wire it to Cloudflare’s CDN, and make sure the whole pipeline is ready for very-frequent traffic without surprise bandwidth costs.

The work involves:
• Creating and configuring the R2 bucket with public read access, optional signed URL support, and sensible lifecycle rules.
• Connecting that bucket to a custom domain (e.g., media.example.com) using either the native R2 → CDN route or a lightweight Worker, with HTTP/3 enabled.
• Tuning cache and Edge TTL settings so my media is served globally with minimal latency while allowing instant purges when a file is replaced.
• Supplying concise documentation or Terraform/Wrangler configs so I can replicate the setup in another account.

Acceptance: a test 4 K video and a handful of images that I upload myself must stream or download from multiple regions with a TTFB consistently under 200 ms. Once everything runs smoothly, I’ll take it from there.
