SOFTWARE UPDATE CONTROL DEVICE, SOFTWARE UPDATE CONTROL SYSTEM, SOFTWARE UPDATE CONTROL METHOD, AND RECORDING MEDIUM CONTAINING SOFTWARE UPDATE CONTROL PROGRAM

摘要

Software update processing executed by an information processing apparatus having limited information processing resources such as an edge server in an IoT system is reliably performed without stopping the information processing apparatus. The software update control device 60 includes a first execution control unit 61 that constructs an operating environment after software update in the second information processing system 80, a verification unit 62 that verifies the updated operation, and a first A takeover control unit 63 that moves the operating environment before the software update in the information processing system 70 to the second information processing system 80, and a second execution control unit 64 that causes the second information processing system 80 to execute the updated software. And a switching unit 65 that switches the processing target information of the second information processing system 80 from information obtained by executing the software before update to information obtained by executing the software after update.
