Patent ID: 11403126

Abstract:
A redundant system (1) includes information processing apparatuses (10), each of which includes a communication interface (11) that communicates with another information processing apparatus (10) and a controller (13) that manages virtual environments capable of running on the respective information processing apparatus (10). The communication interface (11) transmits first equalization information associated with a first environment, among the virtual environments, in an operating state to the other information processing apparatus (10). The communication interface (11) receives second equalization information associated with a second environment in the operating state on the other information processing apparatus (10) from the other information processing apparatus (10). The controller (13) equalizes the second environment onto the respective information processing apparatus (10) based on the second equalization information received by the communication interface (11). The controller (13) maintains the first environment in the operating state and sets the second environment to a standby state.
