A CDN is a geographically distributed network of proxy servers designed to deliver content to users with high availability and performance. CDNs cache static assets (like images, CSS files, and videos) on edge servers close to the end user, drastically reducing load times and offloading traffic from the origin server. As explained in System Design Fundamentals , CDNs are a key component in the architectures of companies like Netflix for delivering movies.
