Enhancing VM Migration Performance in Cloud Environment

Cloud computing is a technology that used for distributed computing, on a network. It is meant network-based services that these services are provided by virtual ISPs. Virtual machine migration has been tout as one of the crucial technologies that improving data center efficiency, such as maintaining load balance and reducing energy cost. However, traditional approaches of could not avoid the service interruption completely. These techniques are deficient, when the entire cluster needs to be migrated. In these methods, Moreover, they often result in longer delay and are liable to failures. In this paper, we discussed the migration techniques existing today, and proposes a new approach of VM migration. In new approach we uses the monitoring technique for take decision of destination host and a additional hardware is use for pre-copy of process data and sent to destination host during the VM migration process. which reduces the total migration time of virtual machine in datacenter. Migration refers to a transparent transfer of an active guest or virtual machine from a source server to a chosen destination server.
