How to Choose the Right CDN
- Budget: Cloudflare (free) and Bunny CDN ($0.01/GB) offer the best value.
- Cloud ecosystem: Choose the CDN that matches your cloud provider (CloudFront for AWS, Cloud CDN for GCP, Azure CDN for Azure).
- Security needs: Cloudflare and Imperva offer the strongest integrated security.
- Developer experience: Fastly and Cloudflare Workers offer the most programmable edge.
- Traffic volume: For very high traffic, pay-per-use providers (Bunny, KeyCDN) may be cheaper than fixed-price plans.
For most websites, Cloudflare's free tier is the best starting point. Upgrade to a paid CDN only when you need specific features like real-time purging (Fastly), cloud integration (CloudFront), or advanced security (Imperva).
