Information providing apparatus, information providing method, and computer product

An information providing method of a computer having access to a storage configured to store at least one among a planned backup date for a process result of information processing related to a service and a planned restore date for the information processing related to the service using the process result, the information providing method comprising:

• inputting an inquiry for a change date candidate for changing specifications of hardware resources allocated to a virtual environment for the information processing related to the service, the inquiry including information identifying a third period;
• determining as the change date candidate, a date within a first period, a second period, and the third period, the first period being from a date of input of the inquiry until the planned backup date and the second period being after the planned restore date, by referring to the storage;
• determining a date within the second period as the change date candidate when the planned backup date is later than the planned restore date;
• and
• outputting the determined change date candidate;
• when determining the change date candidate is within the second period:
• acquiring traffic information within the second period;
• summing traffic information for respective days of a week within the second period;
• calculating a day of the week among the respective days of the week with a smallest traffic volume;
• and
• calculating and setting a date corresponding to the calculated day of the week within the second period as the change date candidate.

A non-transitory computer-readable recording medium storing an information providing program that causes a computer having access to a storage unit configured to store at least one among a planned backup date for a process result of information processing related to a service and a planned restore date for the information processing related to the service using the process result, to execute a process comprising:

• inputting an inquiry for a change date candidate for changing specifications of hardware resources allocated to a virtual environment for the information processing related to the service, the inquiry including information identifying a third period;
• determining as the change date candidate, a date within a first period, a second period, and the third period, the first period being from a date of input of the inquiry until the planned backup date and the second period being after the planned restore date, by referring to the storage;
• determining a date within the second period as the change date candidate when the planned backup date is later than the planned restore date;
• and
• outputting the determined change date candidate;
• when determining the change date candidate is within the second period:
• acquiring traffic information within the second period;
• summing traffic information for respective days of a week within the second period;
• calculating a day of the week among the respective days of the week with a smallest traffic volume;
• and
• calculating and setting a date corresponding to the calculated day of the week within the second period as the change date candidate.
