What is a CDN?
CDN stands for Content Delivery Network and is designed to improve the download performance of a website that has a global audience. The CDN has an array of servers that are based geographically closer to the web site’s visitors in major Internet traffic hubs. These servers host some or all of the website content meaning that download time for these websites improve significantly.
How does a CDN work?
There are a number of different types of CDN. The majority of CDNs will just host static content, like images, java script and CSS files as these make up the bulk of a website’s traffic. Some CDNs will host all of the content including dynamic pages like html and PHP files.
Nimbus Hosting recommends hosting just static content on a CDN as this reduces the complexity of the hosting solution meaning less downtime and faster refresh time for dynamic content like PHP/ASP files. Based on the site’s we host, up to 99% of web site content is static. Visitors will notice an improvement in download speeds of up to 200% by switching to a CDN network.
What are the benefits?
Once a CDN has been implemented on a forum or ecommerce site users will instantly notice an improvement in download times. Research has been conducted to say that this can lead to increased revenue as users can find what they are looking for faster. In the last year Google has also made references to page loading times now becoming a factor in SEO rankings.
From a website’s user perspective they won’t notice any change in the user experience apart from the improvement in download speeds.
