Virtualization is the key to unlocking the true value in a cloud.

In my opinion, for a cloud to be effective — that is, providing the required performance to its customers — it must have virtualization at its heart. This is the only way clouds can quickly ramp up and ramp down to provide disaster recovery solutions internally.

It's where multiple people can use the same computer at the same time each with their own monitor, mouse and keyboard. This saves a lot of electricity and e-waste. A company called Userful recently set a virtualization world record by delivering over 350,000 virtual desktops to schools in Brazil. They have a free 2-user version for home use too.

However, just because you have a large cluster that doesn't mean you shouldn't virtualize. It sure makes managing all of the underlying parts that much easier. I see your points on Google and Yahoo.

I was going to preface my Atlanta comment with "of course, given I live in Northern California..." My Atlanta friends already give me flack for not visiting more. I now have yet another reason to come: so I can check out your traffic firsthand. I always thought of that as a reason *not* to visit. :^)<br><br>And, yes, looking forward to more discussions...<br>--jay Yeah, you got me there.

Virt is the key to many elements of cloud and its one of the "whats changed" answers to why many newer forms of cloud are now possible. IaaS is certainly build and enabled on virtualisation, to give it its on demand nature, computability etc. However as cloud is delivering a services to a protocol it may not be required for say a hadoop cluster that offers a cloud service via an API. Granted I may want to run my own little hadoop cluster virtualised on my own internal cloud and it makes sense for me to run that virtualised. However Yahoo may not want or need to use virtualisatation for their large hadoop cluster. Just like google may not want to run virtualisation for gmail. However these are exceptions to the rule when applications are bing written from the ground up to operate this way. I have probably not made a lot of sense but hopefully enough considering I am typing on the bus. The harbour bridge is covered in cloud this morning (seriously). Well I agree in principal.

You have a lot of other great posts on there that bring up good points. It's true that not everyone's datacenters are 100% virtual - yet. That doesn't mean you can't get there. There really should be no technical reason why you're not 100% virtualized today. Most of the time it's just comfort which happens to be one of the 3 cloud killers.<br><br>BTW, not to nitpick but it's pretty obvious you don't live in Atlanta.

BTW, not to nitpick but it's pretty obvious you don't live in Atlanta. You won't make it too far on a bike and our train system is pretty non-existent. That's why traffic sucks so much here – everyone drives!

Looking forward to continuing conversations.
