What Is CDN And Why You Should Use It For Your Website?

By Faruque Ahamed Mollick

A CDN or Content Delivery Network is a system where all the static contents of your website (mostly CSS, Images, JavaScript) stored on distributed servers around the world in different location and when user access your website then the user will get those Images, CSS, JavaScript from the closest server of the network where the user is located.

That means a copy of your web pages and mostly CSS, JavaScript and images are saved as cached static content on the servers situated at different locations in the world. During accessing your website the network of servers delivers cached static content from websites to users based on the geographic location of the user. Thus it will take less time to deliver.

For an example: If the main server of your website is hosted in Mountain View and someone from Paris tries to access your website, then they will be redirected to the closest server of the network which may be in London. This process help to limits the number of internet hops needed to transmit the static files to your end user.
