A study of big data in cloud computing

Over the last two decades, the size and amount of data has increased enormously, whichhas changed traditional methods of data management and introduced two new technolog-ical terms: big data and cloud computing. Addressing big data, characterized by massivevolume, high velocity and variety, is quite challenging as it requires large computationalinfrastructure to store, process and analyze it. A reliable technique to carry out sophisti-cated and enormous data processing has emerged in the form of cloud computing becauseit eliminates the need to manage advanced hardware and software, and offers various ser-vices to users. Presently, big data and cloud computing are gaining significant interestamong academia as well as in industrial research. In this review, we introduce variouscharacteristics, applications and challenges of big data and cloud computing. We providea brief overview of different platforms that are available to handle big data, including theircritical analysis based on different parameters. We also discuss the correlation betweenbig data and cloud computing. We focus on the life cycle of big data and its vital analysisapplications in various fields and domains At the end, we present the open research issuesthat still need to be addressed and give some pointers to future scholars in the fields ofbig data and cloud computing.
