Security container thermal migration method and system based on SDN (Software Defined Network) synchronization

The invention discloses a secure container thermal migration method and system based on SDN network synchronization. The system comprises a CMM module, a Redis cache control module, an SDN control switching module and a monitoring fallback judgment module. The CMM module is responsible for container migration management; the Redis cache control module is used for being responsible for control management of a cache database; the SDN control switching module is used for being responsible for storing and switching network configuration information of an original container; and the monitoring backspacing judgment module is responsible for monitoring business monitoring and backspacing in the whole migration process. According to the system, in a kubernetes environment, based on a network synchronization switching method of an SDN, by means of virtual machine characteristics of a security container, real thermal migration is achieved, the requirement of a container production environment can be met, and continuity
