In mobile clouds, users accessing cloud services on mobile devices may experience long delays that are detrimental to the user experience. One solution largely investigated is to deploy cloud services on cloudlets, smaller but powerful servers located close to the mobile users. While solving the latency problem, this new model raises two new challenging questions: how to achieve an optimal placement of services on cloudlets and how to minimize the placement transitions of services on cloudlets, both driven by the mobility of the users.
