Now-a-days ‘Big Data’ is one of the much talked about topics. Although data analysis is an indispensable part of modern business, with the exponential proliferation of Internet based transactions, social interactions, location based services and amenities both the scale of available data and possibilities of deriving unforeseen information through data analysis is unprecedented. Therefore, it is very important to have a firm grasp about the technology and tools that companies are using to collect, store and analyze these large volume of data sets known as ‘big data’. This talk will provide a high level overview of ‘big data’ analysis explaining briefly about how some of the very successful companies like Uber, Netflix, Target etc have integrated ‘Big Data’ analysis in their day to day business. The key infrastructure/software components behind ‘big data’ will be presented. Later on the talk will finish by illustrating the capabilities and suitability of python for ‘big data’ analysis.
