Effective management of resource allocation and provisioning cost using virtualization in cloud

Virtualization is the concept of providing efficient solution to the cloud computing paradigm by facilitating creation of Virtual Machines (VMs) over the underlying physical servers, leading to improved resource utilization and abstraction. The proposed method presents a automatic resource management system that makes use of virtualization technology to allocate resources based on application demand for a large scale cloud environment. Additionally Robust Cloud Resource Provisioning (RCRP) algorithm is used in order to achieve the best advance reservation of resources in order to reduce the cost. Maintenance of physical servers can be efficiently achieved through the proposed system as it leads to efficient consolidation of VMs. To analyze the behavior of a Cloud data centers the factors such as elasticity, scalability, live migration of VMs and performance isolation are analyzed by the cloud provider. Experimental results show that the proposed system provides less performance degradation that occurs due to VM migrations. Also the algorithm reduces the SLA violation compared to other techniques.
