Optimum resource allocation approach in cloud

Today's world is an era of information technology in which cloud computing arises as promising and developing technology. In cloud computing environment the resources are provisioned on the basis of demand, as and when required. In cloud computing a large number of cloud users can request a number of cloud services at the same time. So there must be an efficient way in which all the resources are made available to the requesting user to satisfy their needs. Therefore, an optimal resource allocation is one of the central challenges in cloud computing. In this paper, an approach for optimum allocation of resources is proposed in which different types of resources (virtual machine) are allocated by taking three parameters into consideration: processing element, main memory, and network bandwidth. Users are allowed to submit the parameters during job submission. The user inserted parameters will then be considered while allocating resources to them. The simulations of cloud environment are achieved with the help of CloudSim simulator. The objective of this paper is to make optimum resource allocation and achieve efficient utilization of resources over public cloud. The experimental results show that the proposed approach provides better utilization of resources and also there is a reduction in request loss as compared to the Round Robin approach of resource allocation.
