Architecture of an end-to-end energy consumption model for a Cloud Data Center

Estimates show that a significant proportion of future ICT related energy consumption will be from Cloud Computing. Based on detail analysis and survey of energy consumption and optimization trends in cloud computing, this research presents a comprehensive end-to-end energy consumption model of a cloud facility extending from the end-user equipment to the data center facility. The model is subdivided into three planes and four associated layers and depicts the cross-plane and cross-layer relationships between the components in terms of energy consumption and potential optimization areas and provides a reference framework for planning power optimization strategies at a cloud facility.
