What is CDN?
CDN stands for content delivery network. It is a system of distributed servers (network) that deliver webpages and other Web content to a user based on the geographic locations of the user, the origin of the webpage and a content delivery server.
Confused.. let me explain.
Suppose if you open a website xhtmljunkies.com Now it is hosted on a server in USA. So the clients in that geo will have quick response time in terms of page load time. But as we know internet is a network of computers, users/clients in a different geo like say India may face the issue of heavy page load time due to network latency. Now with CDN you will have the same webpage pulled from a local server which is at the nearest location. This facilitates faster page load specially for image intensive web pages/sites.
Why use CDN?
It is highly recommended to use CDN if you have an ecommerce store as most ecommerce stores are content heavy and need to display multiple images on each page for optimal product sale. Customers want to view the product from every angle before buying. Clothing, accessories, jewellery, electronics and many more product categories are heavily dependent on UI/UX for generating sales. Since customers cannot physically touch the product they atleast want to verify the product details virtually by looking at high resolution images which contain visible details related to the product.
How to integrate CDN?
Most ecommerce solutions are built with provisions to integrate CDN from major vendors. If you are a store owner you can contact your technical team or technology partner and ask for integrating CDN services to improve the website performance.
