Computing Frameworks for VM Migration in Cloud

Abstract

Cloud Service users world wide are increasing with advancement in IT infrastructre. This leads to the demand of online storage for various operational reasons. The applications across various organizations are exploiting the cloud infrastructure offered by different service providers like Microsoft, Amazon, Twitter, IBM, and Hewlett-Packard, enable developers to distribute software through a central organization s hosting machine. Online storage is the next logical phase in the development of IT infrastructure. Cloud Storage Infrastructure has become a norm in distributed environment to host the multiple application on easily available networks. Rather than bothering about the Capital Expenditutre, the organizations are now using funds to invest in operational cost of running the services through Cloud service provider increasing the efficiency. While attempting to migrate the workload needs to be considered as imbalanced workload may result in system failure. Also the VM consolidation need to be done while the sytem is live without any failure. The security concerns for live migration are enlisted in limitations which is the largest concern for an organization whle deciding future course of action. This article reviews the cloud computing systems in the light of migrating the existing legacy systems to the cloud environment and suggest the operational features that an organization should consider before the migration.
