Abstract
Recently, federation of clouds drew lots of attentions, by which we can share the virtual resources among private clouds. In the same time, how to provide an easier way of managing the virtual resources while meeting the needs of the users and the different polices of resources providers has become a challenge. In this paper we present a new scheme of VM migration using VM live migration technology in the federated cloud environment. This method will be used to detect the overloaded servers and initiate the migration to the optimized location in the cloud automatically, considering the different locations and policies, thus eliminating the hotspots and balancing the load including CPU, memory and network utilization. According to the experimental result, our technique has been proven that it can detect and remove the hotspots efficiently and balance the load.
