Content Delivery Network (CDN)
Content Delivery Networks (CDNs) are used to provide Internet content from more than one source. For example, if you have a website with a high volume of video content and 10,000 visitors attempt to view your video at one time, they may experience delays if this content is being provided by a single server. This delay may cause your visitors to lose interest and click away. However, if you use a CDN, you could have 10 servers across the network offering your video, increasing buffering speed substantially.
