Description: 

Abstract: Today, large quantities of data are generated from disparate sources such as users, servers, devices, and sensors dispersed around the globe. The need to store, combine and analyze this information in a meaningful and timely manner has resulted in the need for efficient geo-distributed analytics, creating tradeoffs in terms of cost, timeliness, and quality of results. In this talk, I will discuss the challenges of computing with geo-distributed data, and present some of our work on optimizing computation for such highly-distributed environments. I will present new scheduling algorithms we have developed to optimize aggregating data streams in a geo-distributed analytics setting. In addition, I will present Nebula: a dispersed cloud infrastructure we are building at UMN, that uses voluntary edge resources to enable geo-distributed data-intensive computing.
