Step-by-Step Guide
1 Choose a CDN Provider
Popular CDNs include Cloudflare (free tier), Bunny CDN, KeyCDN, and cloud provider CDNs. Consider your budget and geographic needs.
Pro Tips:
- Cloudflare is great for starting out
- Consider edge locations for your audience
2 Configure DNS
Point your domain to the CDN, usually by changing nameservers or adding CNAME records. The CDN then proxies requests to your origin.
Pro Tips:
- DNS changes can take time to propagate
- Use lower TTLs during migration
3 Optimize Caching
Configure cache rules to maximize hit rate. Static assets can be cached longer, while dynamic content needs shorter TTLs.
Pro Tips:
- Use Cache-Control headers
- Set up cache purging for updates
