A systematic overview of live virtual machine migration methods

Abstract

AbstractVirtualization is regarded as one of the key technologies used in cloud computing by means of which virtual resources and dynamic resources are provided for users. Power management, load balancing, online system maintenance are remarkable benefits of virtualization. Such advantages are attributed to the feature of Virtual machine (VM) migration. Many research studies have been recently conducted on live migration and many researchers are seeking to reduce migration time. Prolonged migration time results in some problems especially in WANs which are geographically far from data centers. Hence, the speed of VM transfer from the source to the destination is reduced. There are many cases which can affect the migration of the VM. To the best of the researchers' knowledge, there is no comprehensive overview of studies conducted on live VM migration. This paper is aimed at providing a systematic overview and at investigating the literature on live migration. It includes 50 selected research reports which were published between 2011 and 2020. These papers are categorized by year of publication, publisher, number of citations, authors, immigration methods, techniques used, and effective parameters, and different results have been obtained from them, which we have been discussed in the paper.
