Information processing apparatus and method for hybrid cloud system including hosts provided in cloud and storage apparatus provided at a location other than the cloud

An information processing method executed by an information processing apparatus in a hybrid cloud system including hosts provided in a cloud and a storage apparatus which is provided at a location other than the cloud and from and to which the hosts read and write data, the information processing apparatus managing a configuration of the storage apparatus and including:

• a processor coupled to a memory storing instructions to permit the processor to function as:
• a data acquisition unit that monitors occurrence of scale-out of the hosts in the cloud including an increase of a number of hosts which execute a corresponding processing, manages data access frequency including a number of times of accesses from the hosts to each piece of the data stored in the storage apparatus and deviation of data accesses for each of the hosts indicating how many times and which host has accessed which data, and acquires storage information about a load on the storage apparatus from the storage apparatus;
• and
• a data copy management unit that manages copying of the data in the storage apparatus,
• the information processing method comprising:
• a first step, which is executed by the data acquisition unit when detecting the scale-out of the hosts and determining based on the storage information that a first volume, which stores the data from the hosts, in the storage apparatus has a high load, of issuing an instruction to the data copy management unit to copy the data;
• and
• a second step, which is executed by the data copy management unit in accordance with the instruction from the data acquisition unit, of issuing an instruction to the storage apparatus, on a basis of the data access frequency and the deviation of data accesses from the hosts to each piece of the data stored in the first volume with high data access frequency from each host, to a second volume which is different from the first volume and copy the data with high data access frequency from a specific one of the hosts, to a third volume which is different from the first volume and the second volume.
