This document discusses big data and its growth. It notes that in 2000, 2 exabytes of new data were produced, while in 2011 1.8 zettabytes of new data were produced. By 2020, data production is expected to grow 40 times to 35 zettabytes. The traditional 3-4 V's of big data (volume, velocity, variety, veracity) are expanding to 5-7 V's with the addition of viscosity, virality, and value. Examples of big data use cases include sensor data from CERN and jet engines, social media data from Twitter, and transactional data from Walmart. Atos provides big data analytics solutions and has implemented projects for smart metering,
