| TJ.. I think its more about the methodology... It's not just virtulization. I would also state that the term "user" may be clouded over time...(sorry, had to go there)
Lets say there are these large pools of available infrastructure...
Lets say the the app programing across the pool becomes better and better..
Lets say networking improves dramatically, and signal is available most everywhere with much better bandwidth...
And finally, lets say we continue to see explosive growth in new platforms in which the emphasis moves from device processing capability to more of a device connectivity capability that leverages processing capacity in the cloud...
I can see the day in which product manufacturers will build into their products the capacity to connect and communicate on the owners behalf...
We have seen phone home capabilities in commercial application for years, but not using this potential approach.
In the example above... If Maytag builds the capacity in its washers to connect through the net and send service or repair requirements data to a cloud app that processes the request, diagnosis the problem, and sends a firmware upgrade to your washer, who is the user, you, or the washer?
Getting back to the definition discussion and after review a great deal of the content provided by both Cloud Vendors and Standards Boards, I find the most pragmatic definition to date is supplied by the National Institute of Standards and Technology or NIST.
The NIST definition is comprehensive and provides content on various cloud implementations and service models.
I do not have any criticism of the NIST Cloud definition… I will say that trying to explain the 2 page NIST definition of cloud computing to lay persons, or anyone else that requires a very simplistic definition is at best difficult.
I created my own definition that is very simplistic, and in truth mirrors the NIST definition very closely. I like the following a bit better as it is a definition that is short and easy to understand by all that I have shared with thus far:
Cloud Computing = a pool of computing capacity, public or private, that can be provisioned on demand by end users that can expand or contract based on need, and can be measured based on the capacity used.
It’s just my preference, but I think it’s important to address both the public and private side of cloud in a simple definition…
The definition I offer is not perfect to be sure, but it is good enough to establish a baseline in order to have a conversation about what really matters: How can we use this new computing methodology to address enterprise strategic objectives, address existing IT issues, and provide competitive advantage?
This wrangling over a “precise definition” does not address the central issue. The real issue is how to use these new methods to address and solve real problems.
I have been following and commenting on this particular topic for some time and have have appreciated all of the comments posted to date. Many Thanks to all for the sincere participation in such a interesting and timely subject.
