Abstract

Cloud computing is a newly emerging paradigm that allows ubiquitous provisioning of software, platform and infrastructure services and enables offloading the local resources. Data centers, as the main hosts of cloud computing services, accommodate thousands of high performance servers and high capacity storage units. One of the major challenges in cloud computing is energy efficiency. Offloading the local resources increases the energy consumption of the transport network and the data centers although it is advantageous in terms of energy consumption of the end hosts. In this talk, I will present the existing solutions, opportunities and challenges in the design of the Internet backbone with data centers and energy-efficient delivery of the cloud services. A case study will follow by introducing Mixed Integer Linear Programming (MILP)-based provisioning models and heuristics to guarantee either minimum delayed or maximum power saving cloud services. Besides, I will extend the scope of my talk by tackling network-aware intra and inter-data center virtual machine placement with commitment to energy-efficiency. Furthermore, in conjunction with the advantages of the smart grid, I will also introduce the recent research results on the impact of Time of Use (ToU)-aware provisioning on the Opex of the network and data center operators. Opportunities and research challenges in this area including Wireless Sensor Network-based thermal monitoring of data centers, as well as the security and privacy issues will conclude the presentation as a part of the immediate research agenda.

Bio

Burak Kantarci is a postdoctoral fellow at the School of Electrical Engineering and Computer Science of the University of Ottawa. His research at UOttawa is being supervised by Prof Hussein Mouftah who also co-supervised his PhD thesis. Dr. Kantarci received the M.Sc. and Ph.D. degrees in Computer Engineering from Istanbul Technical University in 2005 and 2009, respectively, and he completed the major content of his PhD thesis at the University of Ottawa between 2007 and 2008. He was the recipient of the Siemens Excellence Award in 2005 for his contributions to the optical burst switching research. He has co-authored seventeen articles in established journals and forty seven papers in many flagship conferences, and he has contributed to five book chapters. He is a co-editor of the forthcoming book, Communication Infrastructures for Cloud Computing, which is to be published by IGI Global in 2013. He has been serving in the TPCs of Green Communication Systems Track of IEEE GLOBECOM and IEEE ICC conferences. Dr. Kantarci is a Senior Member of the IEEE, and a founding member of the IEEE ComSoc-Technical Sub-committee on Green Communications and Computing.
