You don’t hear much about CDNs, but a huge chunk of all web traffic today goes through Content Delivery Network servers.
What is a CDN?
CDN stands for Content Delivery Network, a worldwide network of servers that can be used to deliver content, such as images and videos, to the end user via the fastest route. For example, website owners can use a CDN to make web pages load faster.
Why use a CDN?
The purpose of a Content Delivery Network (CDN) is to deliver web content quickly and efficiently to end users. The internet is a web of networks and failure or congestion in one of those networks, therefore, causes delays. When a site’s loading time is slow, many a web surfer quits and that is why content providers turn to a CDN to ensure that their traffic is always optimized.
CND under the hood
That is why a CDN consists of a lot of extra servers that are placed at data centers and ISPs. Each CDN uses a different approach to deliver content efficiently. Providers, such as Akamai, have a policy to be as close to a user as possible. In order to deliver the cast web content as directly as possible. CDNs are not paid for by the network operators, but by content parties who want to ensure that their web traffic is delivered quickly and efficiently to customers.

Website Loading Speed
Preventing website delays is an important issue for all websites today. Search engines (Google, Bing, Yahoo etc.) make no secret of this: loading time is an important criterion. The CDN shortens the response time of your site and improves the loading speed.
