Abstract-The convergence of mobile computing and cloud computing enables new multimedia applications that are both resource-intensive 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. I. INTRODUCTION The convergence of cloud computing and mobile computing has begun. Apple's Siri for the iPhone [1], which performs compute-intensive speech recognition in the cloud, hints at the rich commercial opportunities in this emerging space. Rapid improvements in sensing, display quality, connectivity, and computational capacity of mobile devices will lead to new cloud-enabled mobile applications that embody voice-, image-, motion-and location-based interactivity. Siri is just the leading edge of this disruptive force. Many of these new applications will be interactive as well as resource-intensive, pushing well beyond the processing, storage, and energy limits of mobile devices. When their use of cloud resources is in the critical path of user interaction, end-to-end operation latencies can be no more than a few tens of milliseconds. Violating this bound results in distraction and annoyance to a mobile user who is already attention-challenged. Such fine-grained cloud usage is different from the coarse-grained usage models and SLA guarantees that dominate cloud computing today. The central contribution of this paper is the experimental evidence that these new applications force a fundamental change in cloud computing architecture. We describe five example applications of this genre in Section II, and experimentally demonstrate in Section III that even with the rapid improvements predicted for mobile computing hardware, such applications will benefit from cloud resources. The remainder of the paper explores the architectural implications
The authors of REF confirm that proximity to data centres is critical for mobile applications that are highly interactive and resource intensive.
