Content distribution is the “product” for many Internet businesses: ISPs, ASPs, and online media providers use these applications to push content across private networks to multiple points-of-presence. The video broadcasting industry pushes even more massive amounts of data across their own specialized networks. These businesses are service providers that are often subject to SLAs that specify financial penalties for downtime and poor performance. Content distribution applications require highly scalable bandwidth for both data networks and storage I/O.
