What is a CDN and the Advantages of CDNs for website hosting?

Utilising a CDN (content delivery network) will have a huge impact on your website and its services. A CDN helps in increasing your website’s speed and improving its performance. It also ensures that the end users receive the same quality experience, when accessing your site from any part of the world. To decide whether one should use CDN with cloud hosting or not, you will first need to understand the meaning and working of CDN.

What is a CDN?

A CDN is a network of servers which are located in various data centers which are usually located across the globe. The CDN is responsible for caching your website’s content, like the images, HTML pages, JavaScript files, stylesheets, videos etc.

This cached content is then stored on each server, each time a user tries loading a web page, they will be able to receive the files from the server which is geographically nearest to their location.

The user receives content from their nearest data center in the CDN network, instead of receiving it from a farther location on the other side of the world. This helps in improving the latency, allowing the pages and content to load faster. This results in delivery of better quality of content to the users, for example an enhanced gaming experience, improved video streaming and faster downloads.

The final result is attaining superior site performance. Your site visitors will receive fast and consistent content, which will give them an improved user experience. The speed of your website also has a direct impact on the search engine optimization (SEO), as Google takes into account the site loading time, while ranking the sites in their search engine.

Advantages of CDNs

The main purpose of using a CDN is to increase the speed at which the content reaches its end users. However, there are a number of other advantages of using a CDN too:

By delivering high-quality content, CDNs have a deep impact on the website’s performance, unaffected by the location of the users.
  • Reduction in Server Load– If your website tends to receive high volumes of traffic, with sudden increase at certain times of the day, then using a CDN can help you reduce the server load.
