An information processing device of deploying containers on a plurality of physical machines includes: memory configured to store operation history information, the operation history information corresponding to each of the containers deployed on the plurality of physical machines; and processor circuitry coupled to the memory, the processor circuitry being configured to perform processing, the processing including: in response that a first container is to be deployed, identifying from the operation history information a reason why the first container is to be deployed; and determining a physical machine from among the plurality of physical machines by using the reason identified to use the determined physical machine as a target physical machine on which the first container is to be deployed.
