10. Big Data Analytics: A Top Priority in a Lot of Organizations

Big Data has been playing a role of big game changer in most of the industries over the last few years. In fact, Big Data has been adopted by a vast number of organisations belonging to various domains. By examining large data sets using Big Data Tools like Hadoop and Spark, they are able to identify different hidden patterns to find unknown correlations, market trends, customer preferences and other useful business information.

  • Big Data adoption reached 53% in 2017 up from 17% in 2015, with telecom and financial services leading early adopters.Forbes

The primary goal of Big Data Analytics is to help companies make better and effective business strategies by analysing large data volumes. The data sources include web server logs, Internet click-stream data, social media content and activity reports, text from customer emails, mobile phone call details, and machine data captured by sensors and connected to the Internet of Things (IoT).

Big Data analytics can lead to more effective marketing, new revenue opportunities, better customer services, improved operational efficiency, competitive advantages over rival organizations and other business benefits.

  • Commercial purchases of Big Data and Business Analytics (BDA) related hardware, software, and services are expected to maintain a compound annual growth rate (CAGR) of 11.9% through 2020 when revenues will be more than $210 billion.IDC
