In this paper, the authors explain about the energy-aware resource management in a cloud computing system. Much of the existing work assumes that the resource requirements for various applications are known and given as scalar values. However, it is very difficult to know the exact resource requirements, and thus, it is more appropriate to treat resource requirements for applications as random variables with known characteristics. For a desired quality of service, the required total resource amount can then be estimated as a function of the means and standard deviations of these random variables.
