Energetic Resource Allocation Framework Using Virtualization in Cloud

Abstract

Virtualization provides an efficient solution to the objectives of the cloud computing paradigm by facilitating creation of Virtual Machines (VMs) over the underlying physical servers, leading to improved resource utilization and abstraction. Virtualization refers to creating a virtual version of a device or a resource such as a server, a storage device, network or even operating system where the mechanism divides the resource into one or more execution environments. To analyse the behaviour of a Cloud data centres: utilization, availability, waiting time, and responsiveness. The factors that a cloud provider must take into account are elasticity, scalability, live migration of VMs and performance isolation. Live migration of VMs, the process of dynamically transferring a virtual machine across different servers on the fly, has proved to represent a new opportunity to enable responsive and dynamic resource management in modern data centres. Through this algorithm to achieve migrations of VMs on the basis of overloading that occurs a physical server in cloud data centres. As indicated the results, the algorithm provides relatively less performance degradation that occurs due to VM migrations. The SLA violation is also less compared to other techniques and this means the cloud provider will incur less cost from VM migrations. Further, MHOD algorithm performs host selection and VM reallocation quicker than the existing algorithms. Maintenance
