Consolidation in Cloud Environment Using Optimization Techniques

The services offered by cloud computing and its usage are increasing day-by-day. Due to the elasticity characteristic of cloud computing, many organizations are now moving their services on cloud data centers. A cloud disaster recovery requires migration of a VM from one data center to another without disconnecting the user. Live VM migration is a key concept to transfer VM without disrupting services. Server consolidation and scheduled maintenance are added advantages of it. In cloud computing, moving large size of VM from one data center to other data center over a wide area network is a challenging task.
