A resource allocation method, a resource allocation program, and a resource allocation apparatus in which a request reception server subjects an inputted SQL to a syntax analysis. At least one SQL process is extracted from the input SQL, and a resource cost of a database required by a BES (Back End Server) to perform the SQL process for each of one or more process types contained in the SQL process is calculated. Further, an allocation ratio is determined for allocating the resource of a request executing server to a virtualized server in accordance with a resource cost ratio required by each of the BES to execute the SQL process. Additionally, requests are made for execution of the respective BES on the virtualized server to which the resource has been allocated so as to execute the SQL process.
