    Dynamic Resource Management in Clouds: A Probabilistic Approach

    Full text link
    Dynamic resource management has become an active area of research in the Cloud Computing paradigm. Cost of resources varies significantly depending on configuration for using them. Hence efficient management of resources is of prime interest to both Cloud Providers and Cloud Users. In this work we suggest a probabilistic resource provisioning approach that can be exploited as the input of a dynamic resource management scheme. Using a Video on Demand use case to justify our claims, we propose an analytical model inspired from standard models developed for epidemiology spreading, to represent sudden and intense workload variations. We show that the resulting model verifies a Large Deviation Principle that statistically characterizes extreme rare events, such as the ones produced by "buzz/flash crowd effects" that may cause workload overflow in the VoD context. This analysis provides valuable insight on expectable abnormal behaviors of systems. We exploit the information obtained using the Large Deviation Principle for the proposed Video on Demand use-case for defining policies (Service Level Agreements). We believe these policies for elastic resource provisioning and usage may be of some interest to all stakeholders in the emerging context of cloud networkingComment: IEICE Transactions on Communications (2012). arXiv admin note: substantial text overlap with arXiv:1209.515

    Remarks on the structure constants of the Verlinde algebra associated to sl3sl_3

    The structure constants Nλ,μμ+νN_{\lambda, \mu}^{\mu+\nu} of the sl2sl_2 Verlinde algebra as functions of μ\mu either vanish or can be expressed after a change of variable as the weight function of an irreducible representation of sl2sl_2. We give a similar formula in the sl3sl_3 case.Comment: 5 pages, AmsTeX, 1 figure available on reques
