On Service Migration in the Cloud to Facilitate Mobile Accesses
Using service migration in clouds to satisfy a sequence of mobile batch-request demands is a popular solution to enhanced QoS and cost effectiveness. As the origins of the mobile accesses are frequently changed over time, moving services closer to client locations not only reduces the service access latency but also minimizes the network cost for service providers. However, these benefits do not come without compromise. The migration comes at cost of bulk-data transfer and service disruption, as a result, increasing the overall service costs.
