Performance, Fault-Tolerance and Scalability Analysis of Virtual Infrastructure Management System

Abstract

The virtual infrastructure has become more and more popular in the Grid and Cloud computing. With the aggrandizement scale, the management of the resources in virtual infrastructure faces a great technical challenge. To support the upper services effectively, it raises higher requirements for the performance, fault-tolerance and scalability of virtual infrastructure management systems. In this paper, we study the performance, fault-tolerance and scalability of virtual infrastructure management systems with the three typical structures, including centralized, hierarchical and peer-to-peer structures. We give the mathematical definition of the evaluation metrics and give detailed quantitative analysis, and then get several useful conclusions for enhancing the performance, fault-tolerance and scalability, based on the quantitative analysis. We believe that the results of this work will help system architects make informed choices for building virtual infrastructure.
