Application execution system, computer, application execution device, and control method and program for an application execution system

摘要

An application execution system enables stable system operation without being affected by server performance or line quality, and without quitting the application. The application execution system 1 has an application server 2 and an application execution device 4 connected by a first network 6, and has the application execution device 4 and a client terminal 5 connected by a second network 7. The application execution device 4 detects the status of the acquired application 11a, runs the application 11a if the application is normal and has the application server 2 run the application if an error or problem is detected. Based on the execution request from the application execution device 4, the application server 2 runs a substitute application 11b.
