C2EN: Anisotropic Model of Cloud Computing

In Cloud computing, due to non-locale and a multi-tenancy of services and resources, there is a need for sophisticated methods for the metering of efficiency, availability and utilisation of services and resources. Setup and management of computing infrastructure, that is in a state of constant flux, related uncertainties of the state of individual elements as well as levels of their usage per application or user on an hourly, daily, weekly, monthly, and yearly basis - pose serious challenges. This paper describes how the Anisotropic Network concept, with its mathematical apparatus, can be adopted to model, monitor and manage usage of the cloud computing resources and services seen as an elastic network of interacting elements that are in a constant motion. Various aspects of service utilisation prediction and anisotropic resource movements related to the novel Cloud Computing Elastic Network (C²EN) model will be discussed in the context of a mathematical model and experimental results of simulations.
