Swarm Intelligence based Virtual Machine Migration Techniques in Cloud Computing

Cloud computing is a utility where compute resources are accessed on pay-per-use ground. It is enacted through virtualizationwhich is a central technology in cloud computing. Virtualization provides a secure and commendable environment for the functioning of cloud applications. Virtual machine (VM) plays a crucial role in the cloud data center when a host machine is exhausted due to tremendous network traffic, then the load is stabilized by shifting highly loaded VM to the under-utilized host machine. This review article recapitulates energy-efficient VM migration, VM migration techniques, objectives and issues related to it. The existing Swarm intelligence based VMmigration techniques are conferred and compared.
