The content delivery network (CDN) was developed to serve content to Internet users with optimized availability and performance. A CDN typically uses a web of specialized servers that are geographically distributed, helping to accelerate the delivery of content by caching it in multiple locations and then using the closest server to fulfill a request for content from each particular user. As the size and complexity of Internet content has increased over the past decade, the CDN has played an important role in enhancing the user experience, reducing costs, improving security, and managing traffic.
But as web content has increased in size and sophistication, the CDN is confronted with a variety of problems. Streaming media is causing page load times to slow considerably. Dynamic sites are using more sophisticated logic to display complex rendering that can't be cached, and mobile devices are requesting content that is further away from origin servers and that hasn't yet been optimized for these devices.
