Cloud Common Sense
In amongst all the vendor pimping and teenage overexcitement there are folk talking common sense about Cloud Computing. So I am hijacking this blog post that was originally just about the McKinesy report on Cloud and I'm transforming it into a thread of Cloud Common Sense, as picked by the IT Skeptic and you, gentle readers. Feel free to add your own picks but be warned: vendor hype or wide-eyed gushing will be treated mercilessly.
So the first example of Cloud Common Sense was the original post:
Regular readers will know that I hold McKinsey pretty highly amongst that dubious rabble of thinly disguised marketing outsourcers known as 'analysts', those peddlers of meaningless twaddle passed off as research. So when McKinsey say "cloud computing could cost more than twice as much as a traditional IT setup", I'm listening.
McKinsey & Co. analyst William Forrest on Wednesday plans to present a report aimed at debunking cloud computing's appeal for large businesses.
While he admits that the idea of piping in computing power from an external service holds appeal for small and medium-sized businesses with fast-growing and unpredictable needs, Forrest calculates that big companies could end up paying more than twice as much for those services as they would to own the same computing resources in-house...
big businesses are less likely than small companies and startups to need those variable offerings, Forrest says. And in cases like the Christmas shopping season, when large numbers of businesses ramp up their IT use simultaneously, cloud computing providers would face the same peaks as their customers--a situation that Forrest says would raise the provider's prices and erase any savings.
None of that renders cloud computing useless, Forrest argues. In fact, he admits that it offers real breakthroughs for small- and medium-sized businesses.
But given its massive hype--he cites a Merrill Lynch report last year claiming that the technology could make business applications "three to five times cheaper"--the economics of cloud computing need a dose of reality.
A fellow skeptic indeed. Of course, as a good analyst he has used no rigorous research just dodgy extrapolations from ad hoc data, and many of his assumptions are highly questionable. I'd expect nothing else, even from McKinsey. But some of his points are still valid. I look forward to more next week. I'm now a McKinsey Premium subscriber.

More Cloud common sense
Three more reasons not to trust the Cloud, from RWW:
Amazon shut down Wikileaks without means of appeal
Yahoo is shutting down Delicious despite millions following. "if you use the Web as a place to store information then it kind of hurts when a service closes"
Youtube shuts down all sorts of people who make a living from it
Conclusion? the Cloud providers are establishing a record of violating customer trust.
Richard Stallman
If you want a healthy dose of skepticism ("Cloud computing is stupidity") try the musings of GNU and FSF founder Richard Stallman. He's on the Orwellian end of the spectrum.

Even more cloud common sense, from CIO
That's just the best of several points
Cloud is NOT a utility
Even more cloud commonsense from The Troposphere (clever name BTW):

1. Cloud offers less legal protection
2. You don't own the hardware
3. Strong policies and user education required
4. Don't trust machine instances
5. Rethink your assumptions
#1 is the biggie for me. Inadequate legal framework (yet) = Wild West

Sort of reflects the pragmatic view of clouds.
The McKinsey report got alot of press around here, but mostly on the completely narrow view of clouds and the gaping holes in the data. But as you say, thats normal fair for the analyst communities. Within the scope of the discussion he draws some relevant conclusions.
The reality is, if you take a pragmatic view, Cloud represents a set of requirements from IT that have always existed and will always exist. Its the Holy Grail of IT Services infrastructure management. Including, most notably;
* The illusion of infinite computing resources available on demand, thereby eliminating the need for users to plan far ahead for provisioning.
* The elimination of an up-front commitment by users, thereby allowing companies or internal projects to start small and increase hardware resources only when there is an increase in their needs and not have the growing pains of rearchitecting.
* The ability to pay for use of computing resources on a short-term basis as needed (e.g., processors by the hour and storage by the day) and release them as needed, thereby rewarding conservation by letting machines and storage go when they are no longer useful.
Then the ownership models of public, private and hybrid add a dimension to the McKinsey comments that are glossed over. A private cloud just represents an internal deployment model that at least at an infrastructure we have always wanted.
A few technologies in the virtualization and the distribute data models space have created a tipping point that have moved us a step closer to this reality, but it is still a large leap for man kind away from uptopia.
So my view is its 80% the stuff we have always had, and 20% some interesting new technologies which we must adapt our process frameworks (TOGAF, ITIL, Prince2, RQ, Scrum, RUP etc..) to accomodate.

one of the shortest hype cycles of all time
With the possible exception of Twitter, the Cloud must be going through one of the shortest hype cycles of all time. This from Cloud Computing Magazine itself, barely been founded and already putting a damper on:
Forbes makes sense about the Cloud
Here's another discussion that made sense to me from Mike Schnaffner:
Although I like most of the thinking, I don't agree that culture is the #1 barrier to Cloud adoption in large enterprise. There are serious issues that are not just in the mind: security, privacy, re-testing legacy, lock-in, escrow... SMEs take risks that larger organisations - quite rightly - won't contemplate.
Common sense defense of the Cloud against McKinsey
Here's a great post from Cloud Ave answering McKinsey but also calling in the more zealous Cloud proponents
...On the Cloud evangelist side, let us be clear about certain aspects of enterprise adoption. It is totally unreasonable for us to expect the enterprises to give up all their past investments and jump into enterprise bandwagon overnight. If anyone thinks that enterprises will immediately embrace the Cloud Computing because of the advantages it offers, they are fooling themselves... there are those companies with huge investments on datacenters and related infrastructure. We cannot expect them to write off all these investments and embrace Cloud Computing... This will be the normal evolution of enterprise IT and any expectations to accelerate the process is unreasonable.
Common sense about the Cloud
great common sense here "Is there any subject in IT today with more promise — or more confusion — than cloud computing? Here are six commonly held views that, while not wrong, are just not entirely accurate"
Another cloud skeptic
...is Tim Bajarin at PC Magazine.
Tim's arguments are just as applicable to outsourcing and supply chain management and EDI and all the other links that run external to our organisations, and one likes to think that large corporations have more external networtk redundancy than consumers do, none the less this is a salient reminder of a basic issue.
presentation of McKinsey Cloud report
This from Uptime appears to be a presentation of the report. It is an excellent read, highly recommended.
