Energy efficiency in cloud computing data center: a survey on hardware technologies

摘要

The internet is expanding its viewpoint into each conceivable part of the cutting-edge economy. Unshackled from our web programs today, the internet is characterizing our way of life, regardless of whether it's sitting in front of the TV or driving an independent auto. The enchantment of the internet appears to be relatively unbounded. In any case, with each new spell there comes an ever-increasing amount of data, and interest for computational power. Cloud computing which is an on-request conveyance of computing power, applications, database storage, and other IT assets by means of the Internet has violently expanded our computerized lives. Though, there have been critical improvements as far as accessibility, fluctuation, time and quality in administrations are concerned; the unbounded development of our computerized way of life requires monstrous measures of power, especially for the data centers that fill in as the mind of the advanced economy. Data organizations foresee a decrease in the quantity of data centers, as more businesses close their little data centers and move towards cloud computing. All things considered, the move by clients towards cloud, will increase the general energy utilization significantly, exceeding any energy productivity increase; which has recorded for over 70% of data center development in 2018. Many research advancements are already made in this domain for minimizing the energy utilization of the computing types of gear included; for efficient power energy consumption, decrease of carbon impression and e-squander. These procedures are supporters of green cloud computing, which are focused on planning and advancing energy-proficient activities to contain inordinate energy utilization in data centers. This paper discusses different mechanisms for lowering the power utilization in data centers. It provides in depth detail about the various mechanisms that can be employed at the hardware component level so that the utilization of energy by component can be reduced. Techniques that can be applied at network, cluster of servers' level along with the various dynamic power management measures that can be employed at the hardware or firmware level and can lead to energy efficient or green data centers are also studied in detail. The paper concludes with the research challenges for building the green data centers.
