Evaluating Energy Efficiency of Data Centers with Generating Cost and Service Demand

Abstract

Cloud computing regards applications (or software) as services. A cloud computing data center must conduct huge amount of computations in addition to traditional server tasks. The energy cost of cloud computing datacenters are therefore staggering high. Cloud service data center has a different power consumption pattern from the traditional storage oriented Internet services. The computation oriented implementation of cloud service broadens the gap between the peak power demand and base power demand of a data center. Improving the energy efficiency is a crucial strategy for overcoming the issue. This paper presents a new model for the energy efficiency of a cloud service data center. This model considers the energy efficiency of both the power demand side and the power supply side.
