Selecting the right CDN provider involves considering several factors. Performance aspects include global network coverage, caching efficiency, and support for HTTP/3 and QUIC. Security features like DDoS protection, WAF, TLS/SSL encryption, and bot mitigation are essential. Pricing models vary, so businesses should assess bandwidth costs, pay-as-you-go vs. fixed plans, and hidden fees. Providers like Cloudflare and BunnyCDN offer free tiers. Scalability, reliability, integration with CMS or cloud platforms, and future-proof capabilities like edge computing and AI support should also be evaluated. Local considerations in regions like China may require using a local provider. Testing through free trials or PoCs is recommended before finalizing a choice.
