The invention discloses a method of adopting a Docker container to realize IoT (Internet of things) information exchange and communication. According to the method, the Docker container is used for building of a virtual data communication environment, a virtual communication layer is built, hierarchical management is carried out on different types of message data in the virtual communication layer, one-to-one, one-to-many and many-to-many information processing mechanisms are realized through a message-driven event mode, and analysis, classification, storage and forwarding operation are carried out on transmitted information. The information exchange speed can be improved, the virtual communication interaction environment reduces the cost consumption of the exchange process, the system is lighter in weight, and besides, the isolated hierarchical information interaction mechanism greatly improves the data safety.
