Abstract
Do you remember the days of physical servers? Generally, the rule of thumb was to have one major role or application per server. That was mainly because many applications and services just did not play well together. They had to be separated, so that they couldn’t fight among themselves and cause problems for users on the network. The unfortunate side effect of this practice was that all of these physical servers were, on average, utilizing 20% of their resources, meaning 80% of those resources were being wasted. We don’t pour a glass of water only to drink 20% of it and waste the rest, do we? We don’t live in only 20% of our homes, do we? Clearly, resource utilization in IT needed a makeover. This is where virtualization technology comes in.
