cPanel Cloudflare Service
What is CDN?
The core feature of the Cloudflare service is the CDN functionality. The abbreviation CDN stands for Content Delivery Network and as the name suggest its basic usage is for distributing your website across several network independent locations around the globe.
Currently the Cloudflare network is powered by 118 data centers around the world. In every single one of these 118 locations, Cloudflare is using a Data Center to host their own infrastructure.
How does the CDN service work?
The static elements are closer to the end user and since those are the largest portion of the website they are loaded fast because of the Cloudflare CDN.
As a result the website loads at least twice as fast to the end user than it normally does when loaded from a webhosting server directly.
Railgun Origin Network Optimizer
Railgun ensures that the connection between the origin server and the Cloudflare network is as fast as possible.
Railgun compresses previously uncacheable web objects by leveraging techniques similar to those used in the compression of high-quality video. This results in an average 200% additional performance increase.
How Can Cloudflare Offer a Free Service?
According to Cloudflare, everything on the Internet (services and information) should be done as quickly as possible.
Using its own advanced service system as well as interaction with other vendors, Cloudflare always strives to reach the closest to zero costs.
Cloudflare are committed to offer a free version with an up-to-date set of features.
