Resource management device and resource management method

A resource management device, comprising:

• data acquiring circuitry to acquire monitoring data indicating a temporal change in a use amount of a resource used in a past by each of one or more containers included in a node among at least one resource of the node;
• prediction circuitry to predict a temporal change in a use amount of the resource to be used in a future by each of the containers from a corresponding one of pieces of the monitoring data acquired by the data acquiring circuitry, and calculate a temporal change in a total use amount of the resource to be used in the future by the one or more containers from a prediction result of the temporal change;
• and
• container deleting circuitry to delete one of the one or more containers when a timing at which the total use amount of the resource becomes larger than a total of the resource of the node is included in the temporal change in the total use amount of the resource calculated by the prediction circuitry, wherein
• the prediction circuitry
• extracts a part of data when a state of the node is a same state or when an environment of the node is a same environment from each of one or more pieces of the monitoring data acquired by the data acquiring circuitry, and predicts the temporal change in the use amount of the resource to be used in the future by each of the containers from each part of the data.
