Energy efficient architectural framework for virtual machine management in IaaS clouds

摘要

Cloud computing is a novel computing model, involving resource outsourcing with infinite and flexible resource scalability and “plug and play” provisioning. The recent materialization of this new computing model has radically changed everyone's perception of infrastructure paradigm, development models and delivery of software. Earlier people were reluctant to go for Clouds due to doubt on performance so since its inception main emphasis has been given on performance so that SLA is not violated. So resources were over provisioned to meet peak demands which resulted in underutilization of servers in off peak hours. This resulted in high power consumption, high carbon footprints and high cooling cost. We are proposing an energy efficient framework for Virtual Machine management which will result in minimum no. of servers used which will further result in low power consumption, low carbon footprints and which will make Cloud computing economical for both consumers and providers. Our model differs from others since we have restricted CPU utilization to a threshold limit as it has been experimentally proved that power consumption increases drastically when CPU utilization increases beyond 70%. Moreover it also gives room for scaling up resources during peak hours.
