Rapid changes 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.
