The Analytical Model and Simulation Research in Phase Space of Cloud Computing

Abstract

A new analytical method based on phase space is proposed for cloud computing which with mass nodes and high coupling characteristics.By projecting the cloud computing system into parametric phase space,the changes of nodes parameters can be translated into the motion of points in the phase space.By making use of the resemblance between the motions of mass points which in parametric phase space and in thermodynamic system to define and analyze the general phase space thermodynamic parameters of cloud computing system,and also define the momentum phase space of cloud computing based on the general thermodynamic parameters.This paper establishes a basic theoretical model for the phase space analytical method of cloud computing and generates a phase space scheduling algorithm based on this model.The simulation experiment shows that the analytical model of phase space is helpful to analyze the service behaviour of cloud computing system and the scheduling algorithm is effective to manage the cloud computing system which can maintain the system in equilibrium state with low entropy in parametric phase space.
