Cloud computing is the hot buzz phrase. But as both Shawn Powers and I have pointed out, cloud computing is not a new technology, or even a new implementation of new technology. But that does not mean it is well understood, either by those who are designing or those who are crying out for it as they follow the yellow-brick road (or the latest issue of PC Week). As several Anonymous (and not so anonymous) commentators have said, there is a lot more to cloud computing then just hardware, some good data links and some smart coding.
