Which CDN provider should I choose?

The best CDN provider depends on your needs. Cloudflare offers the best free tier and integrated security. AWS CloudFront integrates deeply with AWS services. Fastly excels at real-time cache purging and edge computing. Akamai leads in enterprise features and global reach. Consider your traffic patterns, budget, and required features.

What is the difference between Cloudflare and AWS CloudFront?

Cloudflare operates its own global network with integrated DNS, WAF, and DDoS protection in every plan. CloudFront is tightly integrated with AWS services, offers pay-as-you-go pricing, and is ideal for AWS-hosted applications. Cloudflare is simpler to set up; CloudFront offers more granular configuration for complex architectures.

Are free CDN plans sufficient for production websites?

Free CDN plans like Cloudflare Free can handle production traffic for many websites, offering basic caching, SSL, and DDoS protection. However, they lack features like advanced WAF rules, image optimization, custom cache rules, priority support, and detailed analytics that production sites with significant traffic typically need.

How do you migrate between CDN providers?

CDN migration involves updating DNS records to point to the new provider, configuring caching rules and SSL certificates, testing with a staging domain, implementing a gradual rollout using weighted DNS, monitoring performance metrics during transition, and maintaining the old provider as a fallback until the migration is verified.

What is a multi-CDN strategy?

A multi-CDN strategy uses multiple CDN providers simultaneously to improve reliability, performance, and availability. Traffic is distributed based on geography, cost, or performance metrics using DNS-based or application-level routing. This approach eliminates single-provider dependency and can optimize costs by leveraging each provider's strengths.
