How to create your CDN using DNS

We already showed you what DNS is but do you know what CDN stands for?

A CDN – Content Delivery Network is responsible for the content delivery. We all interact with CDNs on a daily basis – when we watch a video, when we read an article, when we shop online or when we use a social network site. The main reason why they exist is to reduce latency, the delay between your demand and the moment it gets on your screen. Higher latency makes us impatient and gets us angry. There are many reasons it can happen, but the main is the physical distance between your computer and the server which hosts the website. CDN makes the magic of shortening that distance, and by doing so, it improves the speed dramatically.

How does a CDN work?

To shorten the physical distance between the users and the hosting server, the CDN keeps cached versions of the original content in different geographical locations known as Points of Presence (PoP). Each of these PoPs is located strategically to serve to the users nearby.
This way, you as a user, don’t need to connect to the original source (the original server). The CDN will direct you to the closest connected server on the network, and you will get the cached version of the original version.

The benefits of a CDN

1. The most obvious is the speed. The content loads faster. According to recent tests from the Content Delivery Network KeyCDN, using a CDN reduces website latency on average by 73% compared to websites running without a CDN.
2. Handle heavy traffic. The load is handled between the PoPs and it is not so heavy for the original server.
3. It reduces the bandwidth consumption.
4. It is more secure and protects you from DDoS attacks, more Points of Presence (PoPs), fewer chances your original server to be affected.
5. Faster loading time will improve the SEO of the website.
There are more benefits but these are the main. Based on these advantages, the CDNs are getting more and more popular every day. Especially for E-commerce and Entertainment.
