APPLICATION SERVER, CLOUD DEVICE, STORAGE MEDIUM ACCESS MONITORING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM HAVING COMPUTER PROGRAM STORED THEREON

摘要

Provided are an application server, etc. which can solve the problem of delay in access to a storage medium experienced by an application program running on the application server. This application server is equipped with: an execution unit which executes an application program in response to a request from a client device, and returns a response to the client device; a measurement unit which measures a value representing an access performance for a storage medium exhibited when the application program is executed; and a management unit which performs control to add another storage medium if the management unit determines, based on the value measured by the measurement unit, that the access performance for the storage medium is degraded.
