Energy Efficiency for Data Center and Cloud Computing: A Literature Review

Energy consumption cost and environmental effect are dynamic challenge to cloud computing. Data centers are the backbone of cloud computing. They continue to be challenging problems to energy efficiency. We investigated previous research based on energy efficiency approach and obtained the conditions to facilitate green cloud computing. Reducing energy consumption and emissions of carbon dioxide (CO2) in data centers represent open challenges and driving the future research work for green data centers. It is found that there is an urgent need for integrated energy efficiency framework fordata centers which combines a green IT architecture with specific activities and procedures that lead to minimal impact on environment and less CO2 emissions. The required energy efficiency framework should also consider the social network applications as a vital related factor in elevating energy consumption, as well as high potential for energy efficiency.
