A CDN is made up of servers distributed over the world in such a way that they can better serve web content. The idea is that adding more servers to cache content will bring it closer to the user; thus, charge download times, site performance, and latency reduction. CDNs can be especially beneficial for web pages intended for audiences from all over the world, very large media files, or even a considerable amount of traffic. In addition, these are much atop protection settings with their planned mitigation for DDoS attacks and the promised accessibility for content even when the servers go down. Cloudflare, Akamai, and Amazon CloudFront are among the major CDNs available.
