CloudSim's Virtual Machine Allocation Policy in a Cloud Computing Environment
In the present paper we are examining the CloudSim, a cloud computing scenario framework simulator and the Virtual Machine (VM) Allocation Policy. The process of virtually allocating the machines is an essential part of the cloud resource management that depends on its capability of changing the performance and energy costeffectiveness of a system and how costly a cloud resource can be. CloudSim enables the generality of customizing the virtual machine allocation policies, hence, enabling several simulation scenarios to be formulated depending on different resource delivery procedures as well as the workload status. This article reviews the same as concerns the functionality as well as the effects of various allocation strategies like the time-shared or space-shared rules on how resources are used and tasks executed. In the investigation, it is established that the increase in performance and scalability of cloud infrastructure may be optimized by the virtual machine allocation algorithms. Researchers can model new methods and test systems and thus because of flexibility, it is important to know that CloudSim is a useful tool in efficient allocation of virtual machines in dynamic clouds research.
