The study on data security in Cloud Computing based on Virtualization
Fu Wen, Xiang Li · 2011
Cloud computing is defined as a pool of virtualized computer resources. Based on this Virtualization the Cloud Computing paradigm allows workloads to be deployed and scaled-out quickly through the rapid provisioning of VMs or physical machines. A Cloud Computing platform supports redundant, self-recovering, highly scalable programming models that allow workloads to recover from many inevitable hardware/software failures. A virtual appliance relieve some of the notable management issues in enterprises because most of the maintenance, software updates, configuration and other management tasks that they are automated and centralized at the data center by cloud provider responsible for them.
