Abstract

A request distribution system connected with a first and second processing system to adjust resources for use in request processing according to a received request amount includes a reception unit that receives a request, and a determination and a transmission unit. The determination unit determines a processing system as a transmission destination. The transmission unit transmits the request to the determined processing system. When a processing system for processing a request from a predetermined network system is switched from the first to the second processing system, the determination unit determines the first and second processing systems as respective transmission destinations so that the requests are distributed to the first and second processing systems between a start and end of the switching. When the second processing system is determined as the transmission destination per the amount of requests, resources to be used in the second processing system request processing are adjusted.

First claim

What is claimed is:

1 . A request distribution system connected with a first processing system and a second processing system and capable of adjusting resources to be used in request processing according to an amount of requests received, the request distribution system comprising:
a reception unit configured to receive a request; a determination unit configured to determine a processing system as a transmission destination of the request received by the reception unit; and a transmission unit configured to transmit the request received by the reception unit to the processing system determined by the determination unit, wherein, when a processing system for processing a request from a predetermined network system is switched in a switching from the first processing system to the second processing system, the determination unit determines the first and the second processing systems as respective transmission destinations of a plurality of requests so that the plurality of requests received by the reception unit is distributed to the first and the second processing systems during a time period between a start and an end of the relevant switching, and wherein, when the transmission destination is determined to be the second processing system by the determination unit according to the amount of requests, resources to be used in request processing by the second processing system are adjusted.

2 . The request distribution system according to claim 1 , wherein, during a time period between a start and an end of the relevant switching, the determination unit determines the second processing system as a transmission destination corresponding to a part of the plurality of requests received by the reception unit, and determines the first processing system as a transmission destination of requests other than the part of the received plurality of requests.

3 . The request distribution system according to claim 1 , wherein, for the request received by the reception unit and during a time period between a start and an end of the relevant switching, the determination unit determines a processing system as a transmission destination of the request according to identification information included in the request.

4 . The request distribution system according to claim 1 , wherein, when the reception unit receives a first request including first identification information as information of a requestor, the determination unit determines the second processing system as a transmission destination of the first request, and
wherein, when the reception unit receives a second request including the first identification information as information of other than the requestor, the determination unit determines the second processing system as a transmission destination of the second request.

5 . The request distribution system according to claim 1 , further comprising a specification unit configured to specify information indicating a part of users out of a plurality of users belonging to the predetermined network system as specification information for determining a processing system as a transmission destination of the request,
wherein, for the request received by the reception unit and during a time period between a start and an end of the relevant switching, the determination unit determines a processing system as a transmission destination of the request according to identification information included in the request and the specification by the specification unit.

6 . The request distribution system according to claim 5 , wherein, according to a plurality of pieces of identification information included in the request received by the reception unit and the specification by the specification unit, the determination unit determines a processing system as a transmission destination of the request.

7 . The request distribution system according to claim 5 , wherein, even in a case where second identification information included as information of a requestor in the request received by the reception unit is not specified by the specification unit, the determination unit determines the second processing system as a transmission destination of the request when the request includes first identification information that is different from the second identification information and specified by the specification unit.

8 . The request distribution system according to claim 5 , wherein, when an instruction for starting the switching is received by the request distribution system, the specification unit starts processing for specifying a part of information indicating the plurality of users.

9 . The request distribution system according to claim 5 , wherein, when the reception unit receives a request for the first time after an instruction for starting the switching is received by the request distribution system, the specification unit starts processing for specifying a part of information indicating the plurality of users.

10 . The request distribution system according to claim 5 , wherein, in a case where the specification unit starts processing for specifying the information indicating a part of the plurality of users out of the plurality of users until information indicating all of the plurality of users is specified, the specification unit repetitively performs the processing for specifying the information indicating a part out of the plurality of users at intervals of a predetermined time period.

11 . The request distribution system according to claim 1 ,
wherein the first and the second processing systems are each configured with one or more virtual machines as resources offered by one or more server computers, and wherein the resource adjustment includes a change in a number of virtual machines according to the amount of requests from the predetermined network system or a load for processing the requests.

12 . The request distribution system according to claim 1 , wherein the second processing system is a processing system for handling data that cannot be handled by the first processing system in processing the request from the predetermined network system.

13 . A management system including a first processing system and a second processing system and capable of adjusting resources to be used in request processing, the management system comprising:
a reception unit configured to receive a request; a determination unit configured to determine a processing system as a transmission destination of the request received by the reception unit; and a transmission unit configured to transmit the request received by the reception unit to the processing system determined by the determination unit, wherein, when a processing system for processing a request from a predetermined network system is switched in a switching from the first processing system to the second processing system, the determination unit determines the first and the second processing systems as respective transmission destinations of a plurality of requests so that the plurality of requests received by the reception unit is distributed to the first and the second processing systems during a time period between a start and an end of the relevant switching, and wherein, when the transmission destination is determined to be the second processing system by the determination unit according to an amount of requests, resources to be used in request processing by the second processing system are adjusted.

14 . The management system according to claim 13 , further comprising a specification unit configured to specify information indicating a part of users out of a plurality of users belonging to
