CDNs (Content Delivery Networks) are network of servers located on various parts of the world, in which each server tries to deliver the content to the user who is nearest to it. This way the delivering takes very less time, instead of relying on the single server for the whole world. These CDN server catches the static contents like web page themes, images, style sheets and other static scripts and content which will be same for most of the pages in the particular website. As usual the dynamic contents are retrieved from the original server. If you want to buy a CDN for a small website or for your blog it costs much greater than your hosting cost. Even though the costs came down in recent past years, it is still far from our hands to pluck. So what to do? Here comes the free CDN.
Free CDN & Easy Setup
CloudFlare is a new age CDN provider which provides CDN and other services that boosts your website for free. The most astonishing part of CloudFlare is, it doesn’t need any complex set up, just changing the DNS name server to their server is the only thing you have to do to utilize the benefits of CloudFlare. After changing your name server it only took approximately 24-48 hours for CloudFlare to detect your site.
How It Works?
CloudFlare has 14 data centers around the world, soon after your site is recognized by these servers, they watch for the http requests generated and content delivered from your original server. The static files requested by the browsers are cached in the cloudflare’s servers for future use. The data collected based on these is synced over all the 14 data centers over the world. So now your content is distributed all over the world by storing it in the CloudFlare’s servers.
How It Speeds Up Your Website’s Loading Time?
Now consider a new user requesting a page from your server, the requests pings the CloudFlare’s nameservers (As we have already changed it to point CloudFlare’s Name servers) the static content in the posted requests are processed by one of the 14 servers which is nearest to the user location. So the delivering of these static content takes very less time than usual as it is delivered from the shortest distance possile. The other requests from the user are forwarded to your site’s server. So your server has to process only the dynamic content of the pages, not all. This reduces server load, and increases the response time of the server.
To summarize the above process, cloudflare reduces approximately 60 percent of the requests to your server and half of the bandwidth from your server.
