The development and analysis of big data in an IoT environment rely on cyber intelligence technology because many theories and methods are required. Furthermore, certain results should be achieved. The value of big data as an infrastructure of cyber intelligence is about to usher in a long-term research and development opportunity. In addition, the problem of scalability and growth of the data amount can only be solved with the cyber intelligence technology. The development of cyber intelligence, on the other hand, depends on the environment and technology support for big data arising from a multitude of sensors and devices ubiqutoiusly emanating from the IoT. It is necessary for cyber intelligence, just like human beings, to have an extensive knowledge and rich experience. The development of cyber intelligence combined with big data will push each other to form an effective mutual promotion impact. Humans will develop intelligent technology from a new perspective of mechanism, thinking and environment of big data.
