Statistical process control technique: Cloud computing perspective

Abstract

In green computing and cloud computing require efficiency in consolidating virtual machine without degrading quality of service. This study, focus on minimizing the migration of Virtual Machine to produce lowest power consumption. To achieve this objective, a new algorithm is used to calculate on the fly the Lower and Upper Threshold Limit using Statistical Process Control theory. This new algorithm is called Dynamics Threshold Optimize System. Three sigma theories are applied in order to get the desire range for the threshold limit. Result proved that DTOS is improve by 1% compare with fix threshold limit.
