Cloud computing, big data are complementary, cloud computing is the foundation, no cloud computing, can not realize the big data storage and computation; big data is the application, no big data, cloud computing is missing the goal and value. Cloud computing as the bottom layer of computing resources, supporting the upper layer of big data processing, the development of big data, in turn boost the development of the cloud computing industry.

From the current development trend, from the national level to encourage the cloud, digitalization, small to the industry, enterprise level, to carry out information technology changes, on the cloud, mining data. Therefore, in general terms, big data, cloud computing development prospects are very good, in recent years has been from the "conceptual publicity stage, into the stage of substantive development", the future development of a lot of space. Of course, cloud computing, big data below there are many sub-fields, specific to the sub-sector, then, we have to specifically analyze.
