Abstract
From home appliances to industrial enterprises, the Information and
Communication Technology (ICT) industry is revolutionizing the world. We are
witnessing the emergence of new technologies (e.g, Cloud computing, Fog
computing, Internet of Things (IoT), Artificial Intelligence (AI) and
Block-chain) which proves the growing use of ICT (e,g. business, education,
health, and home appliances), resulting in massive data generation. It is
expected that more than 175 ZB data will be processed annually by 75 billion
devices by 2025. The 5G technology (i.e. mobile communication
technology) dramatically increases network speed, enabling users to upload
ultra high definition videos in real-time, which will generate a massive stream
of big data. Furthermore, smart devices, having artificial intelligence, will
act like a human being (e.g, a self-driving vehicle, etc) on the network, will
also generate big data. This sudden shift and massive data generation created
serious challenges in storing and managing heterogeneous data at such a large
scale. This article presents a state-of-the-art review of the issues and
challenges involved in storing heterogeneous big data, their countermeasures
(i.e, from security and management perspectives), and future opportunities of
cloud storage. These challenges are reviewed in detail and new dynamics for
researchers in the field of cloud storage are discovered.
