Cloud computing is an emerging technology for providing infrastructure as a services to cloud users. The infrastructure as a service is based on virtualization where it allocates the virtual machine to user through internet. Virtual machine is a guest machine runs in the environment of host machine. VMI are used to purchase VM instances to run on virtual machine in cloud platforms. The storage of large number of VMI and provisioning remains challenging problem. In this paper, data deduplication is a method used in VMI and various data deduplication methods are available which make VMI storage and provisioning to be easy.
