Windows is not going to disappear but it will be much less important in the future. Cloud Computing Much of the computing we do today on our computers in our homes and offices will soon be – so to speak - in the “clouds,” and not on our personal computers, where Windows resides today. Instead, desktop computing on personal computers – featuring full-featured database and spreadsheet capabilities – is being replaced by IT architectures that call for the heavy lifting to be performed by external data centers accessible to us over the Internet. Cloud computing is attracting an enormous amount of attention. The term “cloud computing” is a metaphor that originated with IT architects who routinely used cloud shapes to depict the flow of data from unknown external sources inste...
