Information processing apparatus and information processing method

An information processing method comprising:

• holding, in a storage apparatus of an information processing apparatus, information about:
• specifications that are predicted to be required of a system of a user during each period, a cloud service used for system construction, a construction cost and a running cost of the cloud service, and a migration cost for migrating between two of the cloud services, the information being held in a storage apparatus, and information relating to construction experience of the cloud service and migration experience between cloud services, with regards to a business operator providing the user with a managed service;
• and
• executing, by the information processing apparatus:
• processing of identifying combination patterns of candidate cloud services that meet the specifications to be required during each period, based on the information about the specifications and the cloud service;
• processing of calculating, for each of the identified combination patterns, a construction cost of the candidate cloud services during each period, a running cost during an operation period, and a migration cost when migrating the candidate cloud services between each period, based on the information about the construction cost, the running cost, and the migration cost;
• processing of calculating a total cost for each of the combination patterns, based on the construction cost, the running cost, and the migration cost calculated;
• and
• processing of selecting, from among the combination patterns, a combination pattern for which the total cost meets a predetermined criterion, and outputting information about the combination pattern;
• and
• when calculating the construction cost and the migration cost, processing of reducing the construction cost and the migration cost to a predetermined degree in accordance with the presence/absence or degree of construction experience of the candidate cloud services and migration experience of the candidate cloud services possessed by the business operator.
