What does CDN stand for? CDN stands for “Content Delivery Network”. Basically CDN is a system of servers placed over different geographical locations around the world. Whenever any requester request for a resource or file, they get it from the server which is closest to the requestor location thereby making the download faster.
What kind of Files can a CDN deliver?

Any static files like java script, CSS, image files, video files, mp3 files, PDF files etc.
What can not be delivered by CDN?
Any dynamically generated content cannot be delivered by a CDN.  Any dynamically generated files need to be hosted on your server.
As now you have knowledge of what a CDN is let’s discuss how you can be benefited by using a CDN service. I will discuss several parts of this topic.


Why should you use CDN?


Generally browsers do not download more than 3-4 files from same domain at parallel. So if you have more number of static files per page, your page loading will be very slow as the files will be downloaded one by one. On the other side with the increase in the number of requests, your web server will be highly loaded in serving these static files causing unnecessary wastage of network bandwidth. On the other hand if you use a CDN service for serving your static files like CSS, JavaScript, image files etc. the page loading will be faster and you will save band width of your network as the files will be served from other network, off course the load on your web server will also decreases. As in case of CDN service the files are downloaded from the nearest server to the visitor’s location, downloading will be faster and your page will load in no time.


Benefits of using CDN service:


1. Client side user experience is optimized as the static files will be delivered faster to your visitors because they will get the files from the nearest server.

2. CDN network will never get down because if one server is down the files will be delivered from other server. So service will always be available.

3. You will save the bandwidth of your network and load on webserver will decrease as the static files will be hosted in other server.

4. You have got less files to maintain on your server.

5. Over all performance of your website increases and you get more satisfied visitors.


Some of the best CDN service providers:

1. CacheFly CDN

2. GoGrid CDN

3. Edgecast CDN

4. Soft Layer CDN

5. Internap CDN

6. Max CDN

7. Vox Cast CDN

8. Google AppSpot

9. Cloudfront CDN

10. HighWinds CDN

Finally if you have an ecommerce website, online gaming site or any other type of website that receives a significant amount of traffic then a CDN is must to ensure that your users have a reliable user experience. In my upcoming post I will discuss about how to select a good CDN service provider according to your requirements.
