💡 CDN Optimization Tips

→
Maximize cache hit ratio: Set proper Cache-Control headers. Static assets: max-age=31536000,immutable. API: max-age=300,stale-while-revalidate=60.
→
Enable compression: Brotli/gzip reduces text content by 60–80%. Most CDNs handle this automatically — just ensure your origin allows it.
→
Consider multi-CDN: Use Cloudflare for bandwidth-heavy assets + CloudFront for AWS-integrated dynamic content. DNS-level switching.
→
Negotiate enterprise pricing: At 100TB+/mo, all providers offer custom contracts. CloudFront committed pricing can drop to $0.006/GB.
