Big Data 101: Volume, velocity and variety for the uninitiated

Is #BigData just a buzzword, or can the technology live up to the hype? The Big Data ecosystem can seem confusing and impenetrable to newcomers with a bewildering array of proprietary and open-source tools. We'll begin by setting the stage for big data, understanding what exactly has changed over the last decade, the exponential proliferation of data sources, and the consequent evolution of tools to analyse ever-growing data sets. We'll then dive into the fundamentals of big data systems covering technologies such as distributed architectures, Hadoop, MapReduce and Hive in-depth before exploring the dizzying landscape of big data tools, with examples and case studies to illustrate the way.
