Issue 163: iSGTW 24 February 2010
Spotlight on Virtualization

Virtualization — putting all the spinning plates on one stick

Editor’s note: In this special issue, we focus on virtualization, drawing upon the observations and opinions of practitioners in this area and those closely watching its development.

In the words of EGEE director Bob Jones, a computer center operates “a lot like the guy spinning plates at the circus. He’s got more and more plates spinning on more and more sticks, and he’s running around trying to keep them all going.”

How so?

At the typical computer center, one machine is doing graphics, one is doing electronic document handling, and one is doing something else.

“But what virtualization does is put all those plates on one stick,” said Jones. “You don’t need several different physical machines, but have everything running on one machine doing everything.”

As a result, it’s faster and more efficient.

However, virtualization is not a new idea. Virtual memory was developed at Manchester University, UK, back in 1962. In the 1980’s, the IBM virtual machine VM370 allowed hundreds of users to use small slices of the one machine.

So why is virtualization becoming so important now?

And the winner is . . .

A few weeks ago, we ran a story about the “Vote for your favorite Barbie career” contest.

We noted that “Computer Engineer” was a possibility for the first time, and encouraged iSGTW readers to vote.

Now come the official results.
