VM provisioning policies to improve the profit of cloud infrastructure service providers

Cloud computing is an emerging technology in the IT world. Some features of cloud, such as low cost, scalability, robustness and availability are attracting large-scale industries as well as small business towards cloud. A virtual machine (VM) can be defined as a software that can run its own operating systems and applications like an operating system in physical computer. As the number of users increases, allocation of resources and scheduling become a complex task. The optimization of VM provisioning policies offer improvement like increasing provider´s profit, energy savings and load balancing in large data centres. In cloud computing when resource requirement of user´s requests exceed resources limits of cloud provider, to fulfil the requests the cloud provider outsources to other cloud providers resources, this concept is known as cloud federation. In this paper we propose an algorithm for VM provisioning in federated cloud environment. The approach tries to improve the cloud providers profit. We have used the CloudSim to find-out the results and result show that how Cloud federation help to Cloud providers in order to improve its profit.
