CDN is an abbreviation of Content Delivery Network. This network improves website speed and performance. More than 50 percent of online websites are using CDN, so their visitors can get information in a matter of seconds or simply without any kind of delay. Before you know whether you need a CDN for your website or not, you have to understand what CDN is
What is CDN?
It is a content delivery network that delivers data immediately to the users with the mean of cached servers and PoPs (stands for Point of Presence) which are closest to user’s location. This network is used to deliver static content like pictures, videos, web texts, web information, etc.
For example, a site is UK based and a user from America tries to access it. Since the user is far away from the site server, therefore a delay in delivering the data is quite possible without CDN ;since distance is high between user’s server and site server. However, when CDN is there then content will be delivered immediately without any kind of unnecessary delay.
CDN is considered as transparent internet backbone since it connects end user with the site with an exponential speed. With the help of this network, site content is delivered quickly to its visitors no matter what part of the world they are accessing the data.
This network starts when an international site visitors tries to access site information. As soon as he requests an information, a data center of CDN (Pop) that is close to visitor’s location get activated and delivered data to user.
Why Does a Site need CDN?
Now the question is whether you have to use CDN or not.
You need it due to three main reasons:
- High Traffic: Well, a site needs CDN when it generates large amount of traffic all over the world. If a site doesn’t have a CDN then its international visitors have to wait for page loading. It would take some time because information is stored in site’s server which could be miles away from web visitors.
- Large Files: when a site has large media files like a lot of images, videos, etc then it needs a CDN which efficiently deliver these files to end user.
- Page Speed: It is good to know that page speed is one of top sites ranking factors (according to Moz.com). Your page must load quickly. If loading takes time then it annoys your site visitors. He won’t like to wait. He would prefer to go back and then to visit any other site that offers the same information. This way, you will lose your visitors. Search engine will notice this user behavior and thus your site rank will be affected badly. This is what you don’t like. Right? So, it is suggested to use a CDN that helps you boost up your page speed.
Examples of sites which use CDNs are Amazon.com CNN.com
When you don’t need CDN?
It is good to know that CDN is local sites. When you have a small local business website then you don’t need this network. Actually, your local business traffic will be generated from very precise geographical location. Therefore, you don’t need to save its data for international visitors.
Do you really need a CDN?
