More on ROI and the Economics of Cloud Based Services

InformationWeek::Analytics issued a report earlier this month entitled, "Cloud ROI: Calculating Costs, Benefits, Returns," which compares the costs of acquiring hardware and the costs of utilizing cloud based services and the associated ROI. While the basic analysis of the costs makes sense, the comparison is flawed: the difference between the two is cost savings, not ROI.

The spreadsheet attached to the report is fairly straightforward. All costs involved in the acquisition of capital assets vs. leased assets (i.e., on demand) and the related costs are listed and compared. A present value calculation is performed to show the total cost of ownership over a number of years. It is evident that cloud based services are cheaper than acquiring capital assets for the same purpose. This forms the basis for the ROI calculation but the report never actually calculates the ROI; it gives the reader just enough information to be misinformed...

To make the numbers make more sense, the report needs to add a revenue stream. That revenue stream would allow the reader to find the breakeven point. And, if there was enough time, the report could go further and examine the impact of asset lifecycle and the replacement of capital assets versus using leased assets over time. In this case we would see the economic value of using assets on demand instead of acquiring them.

The one statement, from Lew Moorman, Chief Strategy Officer of Rackspace, with which I agree is that organizations need to evaluate how to make cloud based services fit into their IT service catalog rather than whether they can save money by migrating everything into the cloud. The latter discussion is probably not going to be very productive since not all services can be or should be moved into the cloud though, financially, it might make perfect sense. IT and Finance often butt heads.

In previous posts (here and here) I discussed ROI of Cloud Based Services and how it is often confused for cost savings, touching briefly on the concept of breakeven.
