The difference between big data, cloud computing and Internet of Things. Big data focuses on the storage, processing and analysis of massive data, discovering value from massive data and serving production and life; The essence of cloud computing is to integrate and optimize all kinds of IT resources, and provide them to users at a low price through network as a service. The development goal of the Internet of Things is to connect things, and application innovation is the core of the development of the Internet of Things.

The connection between big data, cloud computing and the Internet of Things. On the whole, big data, cloud computing and Internet of Things complement each other. Big data is rooted in cloud computing, and many technologies of big data analysis come from cloud computing. The distributed data storage and management system of cloud computing provides massive data storage and management capabilities, and MapReduce, a distributed parallel processing framework, provides massive data analysis capabilities. Without the support of these cloud computing technologies, big data analysis is impossible.
