2. Introduction to Careers and job roles in Big data

Large volumes of data are getting generated every second and if collected daily, it leads to 2.5 quintillions of bytes of data that is being generated every day.



Almost 90 % of this data is being generated in just the last 2 years which has led to huge outbursts of data. You can assume from the day of its beginning till the last 2 years, the generation of data has contributed only 10 % of the total data available in the world. So data generation is increasing with time and not linear.

So as we have seen the different sources of data and how much data is getting generated daily, we can accomplish that this data is growing at the rate of 40 % compounded annually. If we calculate the entire data that will be generated by 2020, it comes to around 45 ZB that shows how Big data is growing and would be the most demanding technology in the coming years. This will give the Big data professionals a very dazzling future to work with.

Research by MarketsandMarkets approximates that Hadoop and Big Data Analytics market is expected to reach $13.9 billion by the end of 2017.
