Analysis of Energy Consumption in Cloud Data Center Using Green Cloud Simulator

Cloud computing characterizes a novel and potential model for managing and providing ICT resources to remote users based on pay-as-you-go model. Data centers are popular for hosting the cloud computing applications which consumes tremendous amount of energy, contributing to high operational costs and carbon footprints to the environment [2]. The energy dearth, carbon emissions and global warming leads to concerns towards the power consumption of data centers and [3] the analysis of their energy consumption is extremely important. Therefore, we need Green Cloud Computing Solutions to increase energy savings and to reduce CO2 emission. This paper presents the analysis of cloud datacenter energy saving using virtualization and consolidation technologies. The green cloud simulator is used to estimate the energy consumed by data center core components such as servers, network switches, and access links. The simulated results obtained for various-tiers, and virtualization techniques such as DVFS (Dynamic voltage frequency scaling), dynamic power management (DPM), and dynamic shutdown are presented with and without utilizing power reduction schema. This analysis is significant for users and organizations that are looking at Cloud computing as a solution for their administrative, infrastructural and management problems.
