'Content Delivery Network (CDN)' represents a globally dispersed collection of proxy servers and their data centers. Its primary aim is to enhance availability and performance by strategically distributing the service closer to end-users.

CDNs are responsible for delivering a significant portion of Internet content today, which includes web elements (like text, graphics, scripts), downloadable items (such as media files, software, documents), various applications (e-commerce, portals), live streaming media, on-demand streaming content, and social networking services.

The use of CDNs is primarily to minimize latency, the time delay between making a request and its fulfillment. By establishing multiple points of presence (PoPs) nearer to the end users, CDNs facilitate more efficient data access and substantially enhance the user experience.
