The ongoing shift from hardware-based, dedicated network functionality to software-based networking built on virtualized infrastructure appears to be in full swing. Many industry observers believe that Content Delivery Networks (CDNs), which play a critical role in the delivery of high-quality video, provide an excellent use case for deployment within these evolving frameworks. This whitepaper covers the various challenges inherent in that, as well as how operators might evolve their infrastructure and CDN deployments to address those challenges. Finally, we outline four key requirements, or "pillars" of a virtualized elastic CDN, as a way to provide some guidance for operators who may be evaluating solutions.
