"Storing everything on site has data protection challenges. Storing everything in a typical cloud storage provider has performance challenges. The hybrid storage model is not perfect either, the main challenges being sizing the appliance and the bandwidth. The idea of a CDN for storage presents an interesting alternative to all of these options, giving you the data protection advantages of having data offsite and the performance advantages of having it onsite -- or at least really close to onsite."
