Abstract:
Auction mechanisms have recently attracted substantial attention as an efficient approach to pricing and resource allocation in cloud computing. In this talk, I will represent our recent work on online combinatorial auction design for the cloud computing paradigm, which is general and expressive enough to both (a) optimize system efficiency across the temporal domain instead of at an isolated time point, and (b) model dynamic provisioning of heterogeneous Virtual Machine (VM) types in practice. The result is an online auction framework that is truthful, computationally efficient, and guarantees a competitive ratio of 3.30 in social welfare in typical scenarios. I will also present an overview of research work in the networking research group in the Department of Computer Science in University of Hong Kong.
