Title of the talk : Cloud Storage Systems: Latency, Reliability, and Cost

Abstract: Consumers are engaged in more social networking and E-commerce activities these days and are increasingly storing their documents and media in the online storage. Businesses are relying on Big Data analytics for business intelligence and are migrating their traditional IT infrastructure to the cloud. These trends cause the online data storage demand to rise faster than Moore's Law. Erasure coding techniques are used widely for distributed data storage since they provide space-optimal data redundancy to protect against data loss. Cost-effective, network-accessible storage is a strategic infrastructural capability that can serve many businesses. These customers, however, have very diverse requirements of latency, cost, security etc. In this talk, I will describe how to characterize latency. In order to characterize latency, we give and analyze a novel scheduling algorithm. Further, I will present a novel concept of functional caching in storage systems and describe its advantages as compared to duplication in current caching systems. We will validate the results for optimizing a tradeoff between latency and cost using implementations on an open source distributed file system on a public test grid. Finally, I will describe the extensions where the files are video files rather than data files.

Bio: Vaneet Aggarwal received the B.Tech. degree from the Indian Institute of Technology Kanpur, Kanpur, India, in 2005 and the M.A. and Ph.D. degrees from Princeton University, Princeton, NJ, USA, in 2007 and 2010, respectively, all in electrical engineering. He is currently an Assistant Professor in Operations Research at Purdue University and an Adjunct Professor in the Department of Electrical Engineering at IISc Bangalore. He is also affiliated with Computational Science and Engineering Interdisciplinary Program at Purdue. Prior to that, he was a Senior Member of the Technical Staff - Research for about five years with AT&T Labs Research, Bedminster, NJ, USA. Dr. Aggarwal has been an adjunct faculty at Columbia University for two years. His research interests are in the applications of statistical, algebraic, and optimization techniques to communications and networking, distributed computing and storage, and machine learning. Dr. Aggarwal received the Princeton University's Porter Ogden Jacobus Honorific Fellowship in 2009, AT&T Vice President Excellence Award in 2013, and AT&T Senior Vice President Excellence Award in 2014. He also received the 2017 IEEE Jack Neubauer Memorial Award recognizing the best systems paper published in the IEEE Transactions on Vehicular Technology and the 2018 IEEE Infocom Workshop best paper award. Dr. Aggarwal is Senior Member of IEEE, and has been a Program Co Chair for 3rd International Workshop of Software-Defined Data Communications and Storage (SDDCS) 2017. He is serving as an Associate Editor for the IEEE Transactions on Communications and the IEEE Transactions on Green Communications and Networking.
