ABSTRACT
Cloud computing is a powerful technology to perform massive-scale and complex computing. It eliminates the need to maintain expensive computing hardware, dedicated space, and software. Massive growth in the scale of data or big data generated through cloud computing has been observed. Addressing big data is a challenging and time-demanding task that requires a large computational infrastructure to ensure successful data processing and analysis. The rise of big data in cloud computing is reviewed in this study. The definition, characteristics, and classification of big data along with some discussions on cloud computing are introduced. The relationship between big data and cloud computing, big data storage systems, and Hadoop technology are also discussed. Furthermore, research challenges are investigated, with focus on scalability, availability, data integrity, data transformation, data quality, data heterogeneity, privacy, legal and regulatory issues, and governance. Lastly, open research issues that require substantial research efforts are summarized
INTRODUCTION
The continuous increase in the volume and detail of data captured by organizations, such as the rise of social media, Internet of Things (IoT), and multimedia, has produced an overwhelming flow of data in either structured or unstructured format. Data creation is occurring at a record rate [1], referred to herein as big data, and has emerged as a widely recognized trend. Big data is eliciting attention from the academia, government, and industry. Big data are characterized by three aspects: (a) data are numerous, (b) data cannot be categorized into regular relational databases, and (c) data are generated, captured, and processed rapidly. Moreover, big data is transforming healthcare, science, engineering, finance, business, and eventually, the society. The advancements in data storage and mining technologies allow for the preservation of increasing amounts of data described by a change in the nature of data held by organizations [2]. The rate at which new data are being generated is staggering [3]. A
major challenge for researchers and practitioners is that this growth rate exceeds their ability to design appropriate cloud computing platforms for data analysis and update intensive workloads
