Normally the data center admins and network professionals take the hardware virtualization as a new addition and buzz word in the industry . So it will be curious to know that the concept of virtualization dates back to the early days of the computing industry .
As I type this word in my blog the term virtualization is shown as a spelling mistake by my editor . It is quite curious that a word coined back in 1960 did not still become part of the spell check systems .
At that time when computers was so expensive and owned only by nations , virtualization was a nice concept to save hardware cost . But as the business of personal computing progessed IBM dropped the plans for the virtualization as they were primarily a mchine seller and the basic concept of virtualization was against selling more systems .
