TITLE: The Impact of Mobile Multimedia Applications on Data Center Consolidation


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.

Kiryong Ha is a PhD candidate at Carnegie Mellon University’s ECE. He received BS and MS from KAIST in 2005 and 2007. Prior to join CMU, he was a research staff at ETRI, the Korean government research institute, and he worked on virtualization system to provide seamless working environment for mobile user. His research interested spans to mobile computing, virtualization and cloud computing. He is currently working on Cloudlet project under Professor Mahadev Satyanarayanan.
