Investigation on Energy Utilization in Cloud Data Centers
Cloud computing has revolutioned the ICT industry by enabling on-demand provisioning of computing resources. An organization can either outsource its computational needs to the cloud avoiding high up-front investments in a private computing infrastructure and consequent maintenance costs, or implement a private cloud data center to improve the resource management and provisioning processes. The global energy consumption of IT equipment is steadily rising and produces an increasing portion of global energy production. Currently, data centers consume about 1.5% of global electricity production, whereby their total energy usage has almost tripled between 2000 and 2010.
