Abstract
The present disclosure provides a state management method, a method for switching between a master application server and a backup application server, and an electronic device. In present disclosure, the management server updates the recorded backup application server state in time by querying for the connection state of the hot-backup connection between the master application server and the backup application server, and when the master application server is in failure, instead of immediately controlling the master application server and the backup application server to perform switching between the master and backup application servers, the management server controls the master application server and the backup application server to perform master-backup switching between the application servers according to the recorded backup application server state.
