OECD – Content delivery and cloud computing platforms optimize the delivery of content and services across the network. The Internet was designed as an end-to-end network that provided two-way transport between devices and their users at the edge of the network. CDNs are optimized for one-way distribution of video, images, and other content from large content providers such as Netflix or the BBC’s iPlayer to individual users.
Cloud computing is designed to move the computing and storage functionality of the end-user device into the network.
All fixed communications networks share basic economic characteristics. The first is high fixed costs (capital expenditures), both in absolute terms and relative to variable costs (operational expenditures). The numbers vary based on technology and the scale of the network. Under any conditions, though, running a wire into each residence, and linking those last-mile connections through a wired distribution network, is a costly endeavor. In addition to direct expenses, the necessity of digging up streets, gaining access to telephone poles or conduit space, and gaining physical access to homes is a significant burden. more> http://tinyurl.com/lesfj7a
