The content delivery network (CDN) was initially developed to deliver content with higher availability and performance. Using specialized and geographically dispersed servers, the content delivery network would accelerate delivery by caching content in multiple locations and fulfilling requests for content with the closest server.
But as content has become more sophisticated, the content delivery network is facing new challenges. Digital requirements, media streaming and the demand for video are negatively impacting page load times. Dynamic sites are using more complex logic to display complex rendering that can't be cached, and mobile devices are often farther away from origin servers and are requesting content that hasn't been optimized for them.
These changes and others are forcing content delivery networks to evolve. The next generation content delivery network must now include dynamic site acceleration for non-cacheable content, as well as front-end optimization of the code and code delivery. Content and systems are migrating from data centers to the cloud, creating new challenges for acceleration. CDN security is now front and center, especially for retail and financial services buyers. And more content delivery network providers are seeking analytics and monitoring capabilities in order to get a 360° view of customer experience in order to remediate issues and maintain performance. Clearly a new kind of content delivery network is required to meet these many challenges.
