An information processing device includes a processor configured to observe an actual load measurement value of each of change target components that have a dependency relationship with each other from among a plurality of components arranged in a distributed processing system. The processor is configured to calculate a load prediction value until completion of a change processing of all of the change target components based on the actual load measurement value of each of the change target components. The processor is configured to adjust a transmission interval of a change instruction for instructing start of the change processing to each unchanged change target component that has not started the change processing when the load prediction value exceeds a predetermined threshold value. The processor is configured to transmit the change instruction to each unchanged change target component that has not started the change processing at the adjusted transmission interval.
