Content delivery networks (CDN’s) are essential for not only fast websites, but also security. They’re one of the best methods used to prevent denial of service attacks by malicious hackers, and can lower hosting costs as well as time to recover after such attacks occur.

CDN’s capture or “cache” a copy of a website the first time its requested. It then serves that local cached version thus avoiding contacting the original server. This copy is thus able to be retrieved faster resulting in faster page loads, and less traffic.
