TITLE: The Impact of Mobile Multimedia Applications on Data Center Consolidation
TALK SLIDES: pdf
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. However, cloud providers achieve economies of scale by consolidating dispersed compute capability into few large data center, which causes large average separation between a mobile device and its cloud. This critically affects the performance of these interactive applications. How can we reconcile these contradictions? In this talk, we first describe five example applications of this genre and experimentally demonstrate that these applications will benefit from cloud resources even with rapid improvements predicted for mobile computing hardware. We then present quantitative evidence that this crucial design consideration to meet interactive performance criteria limits data center consolidation. Finally, we describe a two level hierarchical structure that is a seamless extension of today’s cloud computing infrastructure to address this challenge.
