I can see the advantages of Cloud computing for application system version maintenance.
Software development companies that charge high prices for ‘upgrades’ need to be able to service multiple old versions of their software. They need test data, frozen operating systems and frozen database management systems. Go ahead and put all of this in the Cloud if the numbers work out.
In respect of mission critical data, can you really justify Cloud when you factor risk into your ROI?
My group had an unpleasant experience the other day – we were contemplating putting up a mission-critical application on Cloud and picked a mainline market player for the hosting.
A couple of days into testing, we found we could no longer connect and were astounded after a couple of hours on the phone to be told that our problem “would be attended to within 48 hours”. When you work in an environment where a 5-minute outage is a long time that was enough for us to decide against hosting with that vendor.
Cloud is one of these areas where the more successful you are the more you find yourself on a treadmill.
I read a couple of days ago that large Cloud providers, including a well-known Cloud computing service provider, may be having problems upscaling.

One thing to remember is many aspects of “Cloud” are not new. Remember “timesharing” back in the 1970s? The writing may be on the wall.
