Agreed 100%. Repeat after me: "the evolution of virtualisation is NOT cloud computing".

If we get this wrong the trough of disillusionment will be longer and deeper as customers realise that the hype of "I can't believe it's not cloud" doesn't live up to the promise of RealCloud™.

I guess then RealCloud™ will become "Cloud 2.0", and what's a meme without a 2.0? :P

Stuart, you make a great point. Private clouds are a big step forward from the current, inflexible and inefficient architecture of private datacenters and start to demonstrate the benefits of moving to the cloud. But the true benefits of massive scalability and paying for what you use are only realized if you're sharing infrastructure on a much broader scale.

Cloud has great potential, but it's not going to eliminate the need for datacenters (especially not overnight). Private clouds (or datacenters that are virtualized and therefore can share some properties of a cloud) should actually help the whole cloud movement.

Hi Ewan, thanks for the post. You bring up a great point, and the reason why we think the market will require multiple IT clouds will be required. Different clouds will be optimized for different applications (e.g., Force.com for business applications), and different clouds will allow optimization at different levels of the stack.

Quick point on Amazon EC2-- at last week's TechCrunch event, Amazon shared that Amazon.com represents only a minority the traffic on EC2 and S3--- their stack definitely isn't just optimized for shopping.

While I agree about some of your points, I don't know if Amazon will run a data centre the way you want it. You mention the constant optimisation by these companies but Google is optimising their data centres for their search application, and Amazon is optimising for their shop.

In both of these cases, running an enterprise application on their computers will be a marginal usage case for them, less than 0.001% of the total usage of their centres, even if you're a pretty huge operation, so they'll spend no time at all optimising for your own usage.

The real reason why you're right has nothing to do with any part of your well written and informative post. Its all about economics. For an enterprise, it doesn't add up to have a mountain of unused capacity (i.e. vm's in a cloud just waiting to be use), lying around. While running datacenters isn't even a core competency of many businesses, its the fact that to be elastic and respond to demand, you just gotta have the excess capacity available. There's a good reason why Ely Lilly lets their scientists fire up EC2 instances to work on test cases, where as they'd be hesitant with internal resources. Moreover, when you need more power, you just buy it from your energy company--you don't build generators for the purpose of providing your own energy cloud.

Its incumbent on the security professionals of the world to hold the enterprise's hand on the flight up to the cloud.

Gartner thinks internal clouds will be the future of IT ops. Of course, they've been wrong before. :^) My notes from Tom Bittman's keynote on this: http://datacenterdialog.blogspot.com/2008/12/from-gartners-data-center-conf-tom.html

Hi Jay, thanks for the comment and a great post. Agree that organizations with hundreds of servers need help managing them more efficiently. But is this the "future of IT"? No way. That's our main point.

As I mentioned in my "Are internal clouds bogus?" post, I don't agree that the number of orgs that could use an internal cloud is "few and far between." Our take is that if you have hundreds of servers you are probably keeping at least some of them in inefficient silos, tied to specific applications and that sharing resources for those apps in a "cloudy" way could be helpful to your cost structure -- and your ability to match your IT to what the business really, actually wants. But you are right on about one thing: the big vendors are not going to be too pleased with the economics that cloud computing will cause. But internal cloud computing could be bad for them, too: orgs will be able to use what they have already more efficiently.
