Abstract This chapter presents a dynamic cloud computing scheme for efficient
resource migration and 3D media content processing in mobile computing envi-
ronments. It elaborates on location and capacity issues to offload resources from
mobile devices due to their processing limitations, towards efficiently manipulating
3D video content. The proposed scheme adopts a rack-based approach that enables
cooperative migration for redundant resources to be offloaded towards facilitating
3D media content manipulation. The rack-based approach significantly reduces
crash failures that lead all servers to become unavailable within a rack and enables
mobile devices with limited processing capabilities to reproduce multimedia ser-
vices at an acceptable level of quality of experience (QoE). The presented scheme is
thoroughly evaluated through simulation tests, where the resource migration policy
was used in the context of cloud rack failures for delay-bounded resource avail-
ability of mobile users.

in the context of cloud computing paradigm. The services offered through utility-
based cloud computing platforms, mainly emerged from the appearance of public
