An information processing system includes a first system and a second system. The first system and the second system each includes: hardware; a compensation section configured to provide execution environments for execution of a process using the hardware of the system to which the compensation section belongs; and a processing section configured to execute a predetermined process in the execution environments provided by the compensation section. The hardware of the first system and the hardware of the second system are different in nature from each other. The compensation section of one of the first system and the second system compensates for the differences between the hardware of the first system and the hardware of the second system to provide the processing section of the other with the execution environments which are not affected by the differences between the hardware of the first system and the hardware of the second system.
