Can you firstly explain the concept of Big Data

Big Data is definitely one of the more fascinating evolutions of the 21st century in the world of IT. It is the term used for a collection of data from traditional and untraditional sources, so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. When we talk about the concept of “data creation & analysis” today, we mean insights that have the potential to transform businesses, gleaned from data that is humungous (Volume), moves too fast or exceeds current processing capacity (Velocity) and comes from varied sources in varied formats (Variety). Data technologies are the tools and processes businesses may use to handle and analyse this huge and complex data.

Some famous names, who have used Big Data successfully are Amazon, Alibaba, Google, Twitter, Facebook and LinkedIn – these companies are the pioneers and have hugely impacted their profits using data analysis.  But volumes of data are relative and there are also smaller companies that have just as effectively used Big Data technologies to gain insights and improve profitability.

Let’s talk about the Big Data skill gap

Business everywhere and of all kinds are rushing to be a part of the data creation wagon. They are all desperately looking out for the right talent with relevant IT expertise and deep analytical skills. According to information technology research and advisory firm Gartner, Big Data will create more than 4.4 million jobs by 2015. However at present there are just not enough skilled professionals to fill up these jobs and businesses are currently short of experts who can work with Big Data tools and technologies, and make sense of unstructured data flowing from mobile devices, sensors, social media and other sources. Businesses are willing to pay well to hire and retain good Big Data talent. Infact according to Jigsaw Academy’s 2014 Salary Report of the industry, average salaries for Big Data professionals with Hadoop skills was Rs 13 hundred thousand per annum. So really, here  is a great career opportunity for those who are interested in the field.

What are the skills one needs to build a career in Big Data?

Well simply put, a Big Data professional would need a combination of technical programming skills, hands on experience with Analytical tools such as statistics, modeling techniques and econometrics and excellent presentation skills. The most commonly used languages are Java, Python, C#, and R which implements MapReduce queries on big databases such as Hadoop, HBase, Cassandra, and MongoDB, and one would need to build expertise on all these. However Hadoop, R and MongoDB are the most popular and so it may be a good idea to begin by learning these first.
