Improving Efficiency of Billing System in Cloud Computing Using Migration of Virtual Machine

Cloud computing is the model for convenient on-demand network access, with minimum management efforts for easy and fast network access to resources that are ready to use. Billing in IAAS is the important and a complex task in all organizations. It is often compromised due to lack of various interactions (consumer, provider, budget, manager, agent and online payment) simultaneously along with necessary features like discount, tax, plan etc. Billing is considered as an essential part of IaaS. In this paper we are increasing the success rate of requests sent by the users to cloud in the billing system. We improve the online billing system by using the phenomenon of migration of virtual machines. Multiple virtual machines are used at the cloud side, in case of failure of one machine the data will migrate to the other machine. When data will migrate from one virtual machine to other due to any failure at first machine, chances of failure of requests sent will reduced.
