Abstract: In recent growth of business challenges the landscape of the cloud computing under major change. Especially the management of datacenter is challenging task because of its increase in capital and operational expenses due to the spending on its workforce. The paramount importance of any data center is to reduce energy cost and computation cost by effectively utilizing the available physical machines. Virtualization is a key technology in datacenter to provide demand specific virtual resources as per application requirement. Migration helps in avoiding under utilization of resources also in overloaded conditions from the flood of requests coming in these days. The trend in choosing the right migration techniques in cloud data center depends on the nature of the deadline it follows from the utilization of the resources. The goals in virtual migration are the effective management in load balancing of servers, reduced power consolidation of server by right model, faster recognition to the server failure and minimizing the overall system maintenance. In this paper, we discuss some of the latest techniques used in the virtual migration based on their key performance metric like total transfer data, migration time and total down time.
