LOAD-BALANCED MIGRATION OF SOCIAL MEDIA TO CONTENT CLOUDS

Cloud computing delivers new computing models for both service providers and individual consumers including infrastructure-as-a-service (IaaS), platform-as-aservice (PaaS), and software-as-a-service (SaaS), which enable novel IT business models such as resource-on-demand, pay as-you-go, and utility-computing. Trends toward mobile media are demanding new paradigms to transform viewer's experience. Cloud mobile media network was envisioned to leverage the emerging cloud-computing technologies to enhance mobile media experience. Previous research defined media cloud from either a cloud-centric view or a media-centric view (e.g., media-aware cloud and cloud-aware multimedia). In this paper, from a system perspective, we aim to decompose the cloud mobile media system into a set of participatory modules. Specifically, we present two alternative viewpoints for the cloud mobile media architecture, including an end-to-end perspective and a layered perspective. These two architectural viewpoints will serve as blueprints to survey existing research efforts and guide future system research.
