Is cloud storage really more power efficient?
There is, however, an often-touted benefit of using the cloud for data storage and that is power savings. Broadcasters are only now becoming aware of the importance of controlling power costs. Moving forward, technical managers can expect federal, state and local government bureaucrats to increasingly drive companies to use less electricity. One proposed way to reduce electrical costs is to move large-scale data storage off site to a server farm.
A huge server farm may be more efficient, have newer servers consuming less power and operate with lower costs than can a local production or broadcast house—right? Cloud storage providers may tell you so, but the real answer requires a bit of investigation.
