A content delivery network (CDN) refers to a geographically distributed group of servers that work together to provide fast delivery of Internet content.
Anybody who has a website or mobile application that’s likely to be requested by more than one user at a time can benefit from a CDN. They are especially useful to large, complex websites with users spread across the globe, and websites or mobile apps with lots of dynamic content.
CDNs have been around since the late 1990s, but traditional CDNs often lag behind advancements in hardware and technology, and can’t provide the same benefits as a modern CDN. Often, these legacy CDNs are not built-in agile software environments, where the company is constantly iterating on products, incorporating customer feedback, and improving the product. These CDNs have been around for five or more years without much change and have critical inefficiencies that modern CDNs have improved upon
