Abstract
This paper deals data processing in cloud computing environments using Big Data applications. It travels around some important areas of analytics and Big Data. One of the best qualities of cloud is sharing of resources and data into data centres on internet. At present various levels of services required to improve execution efficientcy. In today's world Cloud is using big data processing technology to enhance application aggregation, data aggregation and data utilization. Cloud computing is best powerful technology for complex computing. It is used to eliminate expensive computing hardware, dedicated space, and software. Cloud computing is observed large growth in the scale of huge data. How to address big data is a great challenging and timedemanding task. It needs a large computational infrastructure for successful data processing & analysis. In this study the role of big data in cloud computing environment is reviewed. The definition, classification of big data with their characteristics and some discussions of cloud computing are expressed. The relationship between big data & cloud computing, storage systems, Hadoop technology are also elaborateed.
