What is CDN?
A Content Delivery Network (CDN) is a network of geographically distributed servers that cache website content (images, CSS, JS, videos) and deliver from the nearest location. Benefits: Faster loading times globally (less latency), reduced server load, DDoS protection, improved availability, better Core Web Vitals. Popular CDN providers: Cloudflare (also free), Vercel Edge Network, AWS CloudFront, Akamai, Fastly. Implementation: DNS redirect or origin pull. For static websites, CDNs can also enable edge computing. A CDN is especially important for international websites and large media files.
Key Points
- Global server network for content
- Reduces latency through proximity
- Offloads origin server
- DDoS protection included
- Providers: Cloudflare, Vercel, AWS
- Especially important for international sites
Practical Example
“After CDN implementation, our loading time for US visitors dropped from 3s to 0.8s.”
Frequently Asked Questions about CDN
As soon as visitors come from several regions or load time matters commercially: a CDN serves static files (images, scripts) from the nearest edge location and relieves your own server. For local websites with a single-region audience the effect is smaller, but caching and DDoS protection remain valuable.
Entry offerings like Cloudflare Free are free of charge and cover most SME needs (CDN, caching, basic protection). Paid plans with advanced rules, image optimization and support start at around $20–25 per month.
Indirectly yes: load time is a ranking factor via Core Web Vitals, and a CDN noticeably shortens response times — especially for images and static assets. It does not replace a technically sound website, though.
