Keywords: Virtual Machine, Deduplication, LiveDFS, Liquid.



ABSTRACT:Cloud computing is a dominant technology in IT industry for providing different services to users of cloud. One important service is infrastructure as a service. The virtualization is the technique used in infrastructure as a service in which it allocates the virtual machine to user through Internet. Virtual machine which is a guest machine that runs in the host machine environment. Virtual Machine Infrastructure is used to buy Virtual Machine instances to run virtual machines in the cloud platforms. The high overhead of maintaining a virtual machine has been achieved by hardware support such as Intel virtualization technology (VT) by improving the implementation of hypervisor such as KVM, etc. Storage of virtual machine remains a challenging problem because of the high demand of Virtual machine images. A Storage Area Network cannot satisfy the increasing demand of large scale virtual machine hosting for cloud computing because of its cost limitation. The provisioning and depository of a number of Virtual Machine Infrastructure is a challenging problem. The data deduplication is a method used in Virtual Machine Infrastructure and there are various data deduplication techniques which make Virtual Machine Infrastructure storage and provisioning simple and efficient. In this paper, different methods and processes are discussed which is used in deduplication of data to overcome the problems faced in virtual machine images.
