Thanks. Impressive work and I may use some information, but still I'm going to need some charts etc.

Wladyslaw,
Your question is a difficult one on a generic basis for the main reason that most organizations have abandoned the performance engineering principals associated with the conservation of resources finite system resources in the time of cheap and powerful hardware and quite fast internal networks (1gb-10gb). So, if you are moving an existing custom application to “the cloud” for a provider which now charges for every resource cycle of CPU, DISK, MEMORY and NETWORK you are often in for a rude awakening.
For many organization it is cheaper to run existing custom software on dedicated hardware versus the death of 10,000,000 very small and seemingly insignificant price charges.
I see this all the time in our performance engineering practice. We receive weekly calls of desperation where people have moved to the cloud and have either experienced a severe drop in performance because they have a network bound application (and were not aware) and they have just lengthened the network considerably or they have just received their first month’s bill and the combined cycle costs more than exceeded the costs of maintaining the old hardware internally (including power, cooling and space requirements) but the old hardware has already been sold or donated by the finance group (which was driving the “move everything to the cloud to save money!) No going back. They are stuck.
Depending upon the application and the configuration some things can be done in situ to improve the utilization of system resources which are driving either low performance remotely or high costs for the now cloud-based hosting of a resource inefficient application. Barring configuration changes you are generally looking at rewrites and re-architecting many applications in order to capitalize on the potential savings available. Organizations finally have to recognize runway resource use sins in their development shops which have been hidden by years of every cheaper and more powerful servers. There are also times when you can hide network sins by bringing in-house a caching appliance (either commercial or open source) to serve a lot of files locally that would normally come from the web application, thus improving performance by shortening the network length between the client and the node serving up the files. In all cases the lessons are painful and require some unexpected out-of-pocket costs.
It is a painful lesson to be learned in all cases. It’s best to understand how your application operates on its resource fingerprint that you will be charged for before you make the move. You might also consider an “insurance move,” such as leveraging a provider with both physical and virtual hosting in case you want to move some of the nodes to a fixed price physical host. Rackspace is a good example of one such provider.
However, if you have designed your application well and have paid the extra up-front cost associated with reducing to a minimum your resource use fingerprint for your business actions then you could very well have a good sized bonus to moving to a cloud hosted model. Your application also probably works very well on slow networks and older hardware already and really outperforms on faster networks and really moderately priced commodity servers.
There is a short O’Reilly book that you may want to consider as a part of your research, “Cloud Application Architectures” by George Reese. It’s less than 200 pages of quite useful information for those planning to move to the cloud.

Thanks, but I don't need a cloud concept. I need a data table that shows business expenditure before and after going to the cloud. Or time savings before and after, etc.

“…..which has to be super optimistic. “
This sounds painful for your reputation after an actual deployment and a measurement of results.
