Virtualization Risks and associated Issues in Cloud Environment

Abstract

Cloud computing is dynamically evolving with high end services that are available in low costs and are easily accessible on-demand. Virtualization has made it possible to access data and resources from anywhere on a pay-as-you-use basis. With the magnification of cloud applications, there arises a need to identify the risks associated with virtualization technology. One big issue is configuration management of such a heterogeneous network. There is a need to design a secure access mechanism to handle the multi-tenancy. Virtualization faces a big challenge in resource allocation and developing trust among its users. Handling the data migration among virtual machines is another big issue. The evaluation of service level agreement of the service provider is also very important. It must cover all the details of agreement defining all the services that the CSP is promising along with the associated charges in detail.
