What's in a Cloud?What's in a Cloud?Is “Cloud Computing” Just a Buzzword
Looking for Meaning?
We've got this idea that we can create big pools of resources and share them out for fun and profit.
Dynamic, virtualized resource pools
Sufficient resources to meet peak demand
Efficient/effective user identity management
Mapping of users to allocated resources
Magically make it all work without intervention

Wikipedia says: “Cloud computing is Internetbased computing, whereby shared resources, software, and information are provided to computers and other devices ondemand, like a public utility.”
...and...
'A technical definition is "a computing capability that provides an abstraction between the computing resource and its underlying technical architecture (e.g., servers, storage, networks), enabling convenient, ondemand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal
management effort or service provider interaction."'(From the National Institute of Standards.)

Looking for Meaning?
These definitions are solidly vague and firmly amorphous.
A large percentage of the articles on Cloud Computing found when digging for information were arguments about what the term actually means and how it's all supposed to work.
Case in point: Are Private Clouds Hogwash?Michael Neubarth, CIOzone, March 22, 2010
An article discussing blog posts about whether or not “private” clouds are real. It all depends on your definition.

Client side: How to access your cloud
From the client's perspective:This is Client/Server Architecture
Doesn't matter that the server is “virtual”
Doesn't matter that the server will go away when it's no longer in use
Client access is via the InternetStandard protocols
vs. Proprietary protocols and interfaces

Client side: How to access your cloud
Client access is via the Internetvia the InternetStorage is relatively cheap
At the low end, $75/TBBuy two, make RAID
CPU power is relatively cheapPCs are designed for peak load
Bandwidth is relatively rare & expensiveOuch!

Hey! You! Get Off Of My Cloud!Hey! You! Get Off Of My Cloud!The most fascinating cloud conundrum (IMNSHO) is management of identities and rights.
Ten years ago, under contract, I designed a distributed authentication system
Today we have OpenID, which is similar but not complete
In the cloud, we may have multiple identities
Home, Work, 2nd Life, etc.

Hey! You! Get Off Of My Cloud!Hey! You! Get Off Of My Cloud!The most fascinating cloud conundrum (IMNSHO) is management of identities and rights.
Can I create Groups?How do I share virtual resources?
When virtual cloud objects are created, how do we manage rights?
Which rights are appropriate to which objects × groups?
