The convergence of mobile computing and cloud computing enables new multimedia applications that are both resourceintensive and interaction-intensive. For these applications, end-to-end network bandwidth and latency matter greatly when cloud resources are used to augment the computational power and battery life of a mobile device. We first present quantitative evidence that this crucial design consideration to meet interactive performance criteria limits data center consolidation. We then describe an architectural solution that is a seamless extension of today's cloud computing infrastructure.
