Dynamism in Cloud Resource Allocation : A Survey

Cloud Computing is a one of the distributed technology. This technology only paid and use, it provides the various service models on the internet. Such as Iaas, Paas, Saas, it did with scalability, availability, flexibility of resource through virtualization. Virtualization is one of the important technologies of this environment. This model focuses the various resource allocations on a virtual machine with dynamically based on user requirement. It is emulated the various issues and challenges to the virtual machine for resource allocation, that is loading balancing, green computing, optimization, scheduling, on-demand service, migration, etc. In this survey, focus the various technologies and algorithm used in existing dynamically allocation of the different virtual machine, advantage, simulated mechanisms, parameters, and key issues in this environment.
