Delivering Global Content with CDNs CDNs are networks of servers spread around the world. They bring copies of your content closer to users, so pages load faster even when visitors are far from your origin. How they work: edge servers cache static assets like images, CSS, and JavaScript.

Content Delivery Networks for Fast Global Access Content Delivery Networks (CDNs) help your site reach users quickly, no matter where they are. By distributing copies of files to many edge locations worldwide, a CDN reduces distance, speeds up load times, and improves reliability. They also offer protection against traffic spikes and some basic DDoS hardening. How CDNs speed up access CDNs move content closer to users. Edge servers cache images, scripts, and styles, so pages load faster. Requests are directed to the nearest edge location through smart routing, which cuts travel time and avoids congested paths. Cache-control headers guide freshness and reuse, while TTLs balance speed and accuracy. TLS and HTTP/2 or HTTP/3 can run at the edge, reducing handshake delays. A well-tuned CDN also uses health checks and automatic failover to keep sites available. ...
