Prediction method about power consumption by using utilization rate of resource in cloud computing environment

Cloud computing technologies are suited for reducing costs of maintaining IT infrastructure and initial investment. As cloud computing is developed, problems of power consumption for maintaining the cloud computing environment are occurred. So, several studies for reducing power consumption have been performed. However study for predicting power consumption in cloud computing environment is insufficient. Thus, we propose a prediction method about power consumption by using utilization rate of CPU, Memory, and Hard disk. Also, to prove accuracy of our prediction method, we perform CPU test to compare and analyze predictive power consumption and actual power consumption. As a result, average error rate between the predictive power consumption and actual power consumption value is about 4.22% in the CPU test.
