Advantages to Using a CDN Network

What is a CDN Network and How Does it Work?

A Content Delivery Network is a network of proxy servers that delivers content to end-users with high availability and performance. It provides an effective service in consistently speeding the delivery of websites’ traffic as it works by providing alternative server nodes for users to download resources that include images, videos, audio clips, CSS files, and JavaScript. Nodes, also called edge servers, are like octopuses that spread their arms throughout the world, thus making it geographically closer to all users. When a user requests your site, the node closest in proximity will deliver the static content, ensuring the shortest distance, and therefore, the swiftest site experience. Content providers, media companies for instance, pay CDN operators to deliver their content to their audience of end-users; in turn, CDN operators pay Internet Service Providers, carriers, and network operators.

What Does a CDN Provide Us With?

It serves a huge portion of the internet’s content, static mainly. This includes:
– Web objects: texts, graphics, and scripts.
– Downloadable files: media files, software, and documents.
– Applications: e-commerce and portals.
– Live-streaming media and on-demand streaming media.
–  Social networks

What are the Advantages to It?

1.  The biggest asset to CDN is speed and we all know, speed matters! This is due to the distributed data centers all over the world, as mentioned previously.

2.  Different domains: Browsers limit the number of concurrent file downloads to a single domain. Most of them permit four downloads; the fifth one will be blocked until one of the previous ones has been retrieved. CDN files, however, are hosted on a different domain. Therefore, a single CDN allows the browser to download four more files at the same time.

3. Pre-caching: The probability that someone visiting your page(s) has already visited a site using the Google CDN is very high. As a result, the file has already been cached by your browser and won’t need to be downloaded again.

4. Boosts performance and saves money: A CDN distributes the load, saves bandwidth, boosts performance, and reduces your existing hosting costs – mostly for free! It really is a win-win situation.

If your website is available for people all around the world, and you want to maintain a consistent quick service for your audience profitably, a CDN network is what you need. Reach our professional representatives for more information at
