Microsoft Research. Security for the cloud infrastructure: Equation 3 can be used as a basis for quantitative comparison of risks of various alternatives. Suppose that the expected values of threat and vulnerability of the two alternatives Ak and Ai are vktk and viti respectively. Therefore, relative performance of alternatives is:. Lower value of vjtj corresponds to the more attractive alternative, therefore, in order to go to the maximization problem, we should consider the reciprocal values under risk criterion.
Linear scale should be used for comparing the alternatives under risk criterion. In case of relative importance of criteria comparison, it is necessary to take in consideration a requirement of normality:.

Therefore, following simple procedure can be used in practice. The first step is to assign weights Wj and Wj to two random criteria Cj and Cj based on their relative importance.
Absolute values of alternatives in terms of each criterion were estimated by experts. In accordance with rules proposed in Section 3, the entries of S, F and R can be calculated as follows:. In accordance with Section 3. Let use weighted production model WPM to define relative attractiveness of alternatives.
WPM is one of best known and simplest MCDM method for evaluating number of alternatives in terms of a number decision criteria. Suppose that a given MCDM problem is defined on m alternatives and n decision criteria, and all the criteria are benefit criteria, that is, the higher the values are, the better it is.
Let Wj denotes the relative weight of importance of the criterion Cj and ajki is the relative performance value of alternative Ak regarding alternative Aj when they are evaluated in terms of criterion Cj.
So, to compare the two alternatives Ak and Aj the following product has to be calculated :. With given C, S, F and R: Therefore, with given criteria priorities and parameters estimations the best alternative is A2, because it is superior to all the other alternatives.
The ranking of alternatives is as follows: The main goal of paper is to propose simple model that can be used in practice. Three criteria cost of ownerships saving, intangible benefits that associated with speed of reaction to change and security risks that have been proposed here are enough simple and all necessary data can be obtained from accounting system, contract conditions, statistics and expert opinions. The proposed method helps easy to get a consistent matrix of pairwise comparisons.
All of this leads to the conclusion that the proposed method can be used in practice. Marston S. Cloud Computing: The Business Perspective. Decision Support Systems. Armbrust M.
