Energy-Efficiency in Cloud Datacenters: A Survey

Energy efficiency in data centers refers to how effectively any virtualized data center providing cloud administrations may use or use energy. Due to data centers' continued high electrical power consumption, current computer systems have strict energy efficiency requirements to optimize of Energy Utilization. Consequently, the idea of “green cloud computing” was born. Energy efficiency in the clouds, particularly in cloud data centers, were themes covered in many survey articles. In this Survey we focused on energy efficiency of the clouds by using cooling, VM allocation and migration techniques, scheduling techniques, AI technologies to aid in the construction of the green cloud. Our survey also covered the cloud services offered in Saudi Arabia and their comparison. We found that Saudi cloud providers is categorized into different classes, (A), (B), and (C), all of these classes are service providers that qualified to deal with individuals, private sector, non-profit sector, and government sector.
