How does CDN Work?
Content delivery network is a service which can help the static content of your site loads more quickly (Images, CSS, Javascript etc)
A CDN has Points of Presence (PoPs) or data centers which are situated around the world. In each PoP there are several thousands of servers were connected to it. Both the PoPs and servers help to accelerate a lightning speed which the data are delivered to the users.
A CDN is a collection of servers located all over the world. Whenever the user requests content, the request is automatically connected to the server which is closest to the user’s location. This makes your site loads much faster.
If a visitor of a site request any files like images, javascript, CSS files, pdf, zip etc instead of hosting provider responding to these files the Content Delivery Networks loads the files. The file will be served from caching – node closest to your site uses.

Using CDN the data will be available to the users in a lightning speed, independent of the location of website or hosting server. CDN’s are designed to solve the issue know as Latency.
A CDN’s goal is to virtually shorten the physical distance between the user and the hosting server. This is to improve the sites rendering speed and performance of the site. As your contents are loading from many different servers in different locations, the traffic to the servers will be less so your site will open in seconds.
A CDN has proper techniques for preventing, detecting and correcting different forms of DDoS attacks.
