How does Cloudflare work?

With Cloudflare services not only your website will be more secured from DDO’s attackers, but also your website will load much faster and 99% times will be accessible at least the dynamic content in times when your server is not reachable.

The most requested Cloudflare services are Content Delivery (CDN) services [more info can be found here ], security, performance, and reliability for anything connected to the Internet.

Cloudflare is designed for easy setup. Anyone with a website and their own domain can use Cloudflare regardless of their platform choice. Cloudflare doesn’t require additional hardware, software, or changes to your code.

Security:

Cloudflare stops malicious traffic before it reaches your origin web server. Cloudflare analyzes potential threats in visitor requests based on a number of characteristics:

  • visitor’s IP address,
  • resources requested,
  • request payload and frequency, and
  • customer-defined firewall rules.

A DNS lookup of a proxied (orange-clouded) Cloudflare subdomain returns Cloudflare IP addresses. Proxied traffic comes to our edge and then we forward the request to your server. Cloudflare masks your origin IP address for proxied DNS records so attackers cannot bypass Cloudflare and directly attack your origin web server.

Visitor <–[Connection 1]–> Cloudflare Edge <–[Connection 2]–> Origin Server

A DNS lookup of an unproxied (grey-clouded) Cloudflare subdomain returns the IP address that you’ve entered for the record. Unproxied traffic goes directly to your origin server and does not receive any of the benefits of using Cloudflare

Visitor <–[Connection]–> Origin Server

Performance:

Cloudflare optimizes the delivery of website resources for your visitors. Cloudflare’s data centers serve your website’s static resources and ask your origin web server for dynamic content. Cloudflare’s global network provides a faster route from your site visitors to our data centers than would be available to a visitor directly requesting your site. Even with Cloudflare between your website and your visitors, resource requests arrive at your visitor sooner.

Reliability:

Cloudflare’s globally distributed anycast network routes visitor requests to the nearest Cloudflare data center. Cloudflare distributed DNS responds to website visitors with Cloudflare IP addresses for the traffic you proxy to Cloudflare. This also provides security by hiding the specific IP address of your origin web server.

Cloudflare-proxied domains share IP addresses from a pool that belongs to the Cloudflare network. As a result, Cloudflare does not offer dedicated or exclusive IP addresses.

Also, our flat-rate pricing structure provides predictability and reliability in your CDN and DDoS bandwidth expenses. Cloudflare does not have bandwidth limits for domains on the Free, Pro, and Business plans as long as those domains comply with our Terms of Service. However, your hosting provider may still impose limits on bandwidth usage and/or charge for bandwidth.
