Big Data Analytics Issues and Challenges: A Survey

Abstract

In the digital world data accumulation is increasing more and more. Billions of devices are connected worldwide already and expected to connect 50 billons of devices by the year 2020. All devices produce Peta bytes of information by transforming and sharing with light speed on optical and wireless networks. The fast growth of such large data facing numerous issues and challenges in big data analytics, as the rapid growth of variety of data, hardware platforms, software, speed and security. Utilizing the data in decision making is one of the big challenges. Scaling the platforms and frameworks are other important challenges. This paper surveys the characteristics of big data including its characteristics, issues and challenges, right choices of platforms and models depending on their computational requirements and challenges.
