CDN stands for Content Delivery Network. A content delivery network (CDN) is an interconnected system of computers on the Internet placed at geographically different locations, which contain copies of data files to maximize the bandwidth in accessing the data.
In a CDN, content exists in multiple copies on strategically dispersed servers. This is known as content replication. Which of the servers (containing replicated data files) will deliver the web pages or any other web content to the user depends upon the geographic locations of the user. Servers nearest to the website visitor respond to the request.
This service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach. One more advantage of CDN technology is content redundancy that provides a fail-safe feature and allows for graceful degradation in the event of damage to, or malfunction of, a part of the Internet.
Content providers such as media companies and e-commerce vendors pay CDN operators for delivering their content to their audience of end-users. In turn, a CDN pays ISPs, carriers, and network operators for hosting its servers in their data centers.
