No matter if you work with hardware, you are on software development or into the virtualization businesses; at this moment we are all looking for the right definition for this "new thing" that is going on in the computing industry...

Being conscious of the blurry nature of clouds and its perpetually changing nature, it would probably not be a good idea to make hard coded definitions that could probably get biased, incomplete and quickly superseded by reality... But here we can try to find it out, you are invited to define the whole cloud idea, break it down to pieces, or make fine-grained clarifications...

Be welcome, and please help me finding out what Cloud Computing really is and how it will affect our lives.

You're all invited to "Delineating The Cloud" (if you dare;-).

Many speak about a new experimental technology that maybe, someday, could be huge…

Others think out loud: I have seen all this before, Is there really something new going on or is this just the ultimate marketing strategy?

Some of us, we know it all comes to it; it's just natural evolution right? But we don’t really know exactly how, where or why.

And for a few, this is already a new way of life, in fact this few are already writing their own lines in the computing annals.

Why is it so difficult to define Cloud Computing?

My first impression: The difficulty of defining Cloud Computing comes down to:

a) It is very new, but at the same time it recycles lots of very good old concepts, well and some not so good too.

b) Some people are defining what the cloud is right now, while others try to picture what it will be like in the near future.

c) The fact that cloud computing is used to describe many different things...

Premises:

I will try to elaborate a list of premises from where we can try to make a final, more concrete definition. Please help me add and remove or modify premises, no good definition will ever come out if the premises are wrong or poorly defined.

First Premise: Cloud computing happens on "The Cloud", that is, the Internet, so whatever definition we come out with at the end of this process, it has to state that whatever is cloud computing, it happens in "the cloud". Even for that first point, it may exist some discrepancies or exceptions with corporate clouds that may be private clouds connected or not to the Internet.

Second Premise: Cloud Computing is being built on top of utility computing and is delivered as a Service, which is “you pay for what you use”.

Third Premise: Cloud Computing is about connecting computers or enabling them to do so and easy the way they exchange and reuse information, this is usually done by using web services or API’s.

This is not a blog post, it is a "discuticle" an article that is expected to evolve, write it, save it, move it, trash it... then rewrite it, copy it, paste it... you know the song... Please help me keep it alive, at least until we come out with some good definitions that help people understand what Cloud Computing is and why we are so passionate about it. Thank you!
