Big data infrastructures have evolved rapidly as computing power has grown and hardware has become less expensive. This session will be a high level overview of popular big data infrastructures and paradigms over the last decade in both academics and industry. Technologies covered will include Spark, Hadoop, distributed relational databases, grid computing, and high performance computing. We will compare and contrast embarrassingly parallel vs distributed memory algorithms and streaming vs batch processing. Finally, the session will cover some of the modern technology options available for various applications.
