How Does CloudFlare’s Technology Work
CloudFlare’s technology is built like a CDN (content delivery network). It is a cloud-based, distributed network, which means it has multiple data centers spread across the web. When you add a domain to your CloudFlare account, CloudFlare acts as a proxy. This means that your visitor’s requests to your website are routed through the CloudFlare network.
To start using CloudFlare is fairly simple, go to https://www.cloudflare.com and add you site there. It takes around 1 minutes for CloudFlare to check your DNS record. Once verification finished, you must change your nameserver using CloudFlare’s predefined DNS server.
