Content delivery network

A content delivery network, commonly referred to as CDN, is a network of edge servers strategically placed across the globe with the purpose of delivering digital content to users as fast as possible. When a user makes a request it is routed to the nearest CDN edge server, which significantly reduces the latency. A CDN allows all users, no matter the geographical location, to have fast loading content for an unquestionably improved experience.

According to BuiltWith, 66% of the top 10,000 websites are using a CDN (November 2018). This percentage has continually increased over the last 10 years due to the large growth of digital content consumption and high user expectations. Utilizing a CDN is one of the most effective ways to deliver content with high performance and reliability on a global scale.

In fact, a study done by the University of Nebraska found that the tolerable waiting time for information is approximately only 2 seconds.
