Power conserving resource allocation scheme with improved QoS to promote green cloud computing

摘要

Though cloud computing has grabbed the attention of several industrialists and educationalists, the only concern of cloud computing is the uncontrollable rise of cloud data centres. The improper utilization of cloud resources paves way for inefficiency and environmental hazard as well. Understanding the seriousness of this issue, several researchers contribute to promote green cloud computing through different ways. The Green Cloud Computing is the act of executing approaches and the techniques to improve proficiency of the figuring assets so as to decrease the vitality utilization and natural effect of their usage. The power consumption of the data centre offers the features like web based checking, live virtual machine movement, and advancement of Virtual Machine Placement. This work focuses on effective resource allocation scheme for cloud users, which does not compromise on QoS by employing two layers such as Cloud Manager Layer (CMLs) and Green Manager Layer (GML). The CML is responsible for choosing the suitable resources out of all available resources and the GML picks the best one out of it. Due to this optimal selection of resource, the average service response time is reduced at the cost of minimized power consumption. When handling 500 service requests, the proposed work consumes about 4298 W and the comparative approaches consume more power.
