In recent years we have witnessed a rapid proliferation of data globally. The total size of data center traffic is estimated by Cisco1 to be ~2.6 ZB and expected to reach ~6.6 ZB by 2016 at ~31% CAGR over 2011-16. As per Wipro’s estimates, the amount of big data stored globally is to the extent of ~6,500 petabytes.
With data proliferation, there is a greater need to analyze the data and use it to tweak systems and processes as well as provide real business insights. Worldwide business analytics services revenues have thus grown at ~10% CAGR over 2009-11 in a period where overall IT Services spending has grown at ~5% CAGR.
