CDN (Content Delivery Network) is a set of geographically distributed servers designed to cache content to efficiently deliver it to users. Typically structured as a cluster, a CDN allows for the rapid transfer of static data necessary for loading web pages, as well as other media elements, including JS files, HTML, images, and videos.

A properly configured CDN can protect websites against DDoS (Distributed Denial-of-Service) attacks, reducing their impact on project functionality. By distributing traffic to multiple servers, a CDN can absorb and disperse the large volume of requests generated by a DDoS attack, minimizing the risk of overloading the main server.

In addition, many CDNs offer additional security features, such as filtering malicious traffic, blocking suspicious IP addresses, and continuous activity monitoring to detect and prevent other types of cyber attacks.

CDNs are compatible with a wide range of web platforms and technologies, allowing for their easy integration into various infrastructures or panels. Many platforms offer advanced analytics and reporting tools, enabling performance and security monitoring, thereby providing useful data for the continuous optimization of the website.

Among the most popular CDN platforms are: CloudFlare, Fastly, Quic, Amazon CloudFront, Google Cloud CDN.
