Job executing system, job executing device and computer-readable medium

An image forming device includes a monitoring service performing unit and a service process performing instructing unit. The monitoring service performing unit acquires operation state information including index data that represents a service processing function mounted in the corresponding server and an operation state of the corresponding server from each server by starting a monitoring service when an accepted job is performed. The service process performing instructing unit instructs a low-load server to start a corresponding service processing function when the load on a server in which the service processing function used for executing the job is mounted is determined to be high. The server acquires the corresponding service processing function from the server in which the corresponding service processing function is mounted when being instructed to start an operation and thereafter performs the corresponding service process in accordance with the performance instruction transmitted from the image forming device.
