Resource allocation control device, computing system, and resource allocation control method

A computing system comprising:

• a plurality of nodes configured to execute a distributed data store that distributes and manages data;
• and a resource allocation control device configured to control a hardware resource amount of the nodes to be allocated to the distributed data store, wherein
• the resource allocation control device is configured to:
• store application performance information indicating a correspondence relationship between a performance of an application that accesses the distributed data store and executes a predetermined process and a distributed data store performance required for achieving the performance of the application indicated by the stored application performance information, and store data store performance resource amount information indicating a correspondence relationship between the hardware resource amount and a data store performance that is achievable by the distributed data store according to hardware of the resource amount;
• receive target performance information capable of specifying a target performance of the application;
• determine a required performance which is the distributed data store performance required for achieving a performance to be specified by the target performance information based on the application performance information;
• determine the hardware resource amount required for achieving the required performance based on the data store performance resource amount information;
• and
• set the hardware of the determined resource amount to be allocated to the distributed data store.

A resource allocation control method performed by a resource allocation control device that controls a hardware resource amount of a plurality of nodes to be allocated to a distributed data store that is executed by the plurality of nodes and distributes and manages data by the plurality of nodes, the resource allocation control method comprising:

• storing application performance information indicating a correspondence relationship between a performance of an application that accesses the distributed data store and executes a predetermined process and a distributed data store performance required for achieving the performance of the application indicated by the stored application performance information, and storing data store performance resource amount information indicating a correspondence relationship between the hardware resource amount and a data store performance that is achievable by the distributed data store according to hardware of the resource amount;
• receiving target performance information capable of specifying a target performance of the application;
• determining a required performance which is the distributed data store performance required for achieving a performance to be specified by the target performance information based on the application performance information;
• determining the hardware resource amount required for achieving the required performance based on the data store performance resource amount information;
• and
• setting the hardware of the determined resource amount to be allocated to the distributed data store.
