An Energy Efficient Cost Aware Virtual Machine Migration Approach for the Cloud Environment

Virtualization is the driving technology in the cloud which allows application isolation and enables the service provider to relocate the virtual machine (VM) from one server (PM) to another, knows as virtual machine (VM) migration. VM migration is the key features of the virtualization. It facilitates load balancing, hot spot mitigation, server consolidation, fault management, and power saving. VM migration is the multi steps process i.e. source PM selection, candidate VM selection, target PM selection and the last step is transferred VM data. This work proposed a priority-based load balancing approach that migrates and schedules the VM according to the weight or priority which is assign to each VM. In the cloud, when the user uses the cloud resources, some amount (bill) is paid by the user for using their resources. On the basis of this bill, some priority is assign to each user.VM which provides more return to the cloud owner will have more priority and schedule first. The main idea of this approach is that gives better service to those users who gives more profit to the provider. The proposed approach is evaluated in CloudSim simulator and experimental results illustrate that proposed approach gives a better result as compare to the competitive approach.
