(First embodiment)
First, the outline of the information processing system 100 according to the first embodiment will be described with reference to FIGS. 1 and 2. 1 and 2 are diagrams illustrating an overview of an information processing system according to the first embodiment.

  As illustrated in FIG. 1, the information processing system 100 includes information processing apparatuses 10 a and 10 b that provide services to user terminals registered in a first network (American region) 51 and a second network (European region) 52. Prepare. FIG. 1 also shows one or more external devices (A to D) 20a to 20g that provide services in cooperation with the information processing devices 10a and 10b, respectively. Hereinafter, “user terminal” is also referred to as “user”. In the following, “data center” is also expressed as “DC”. In the following description, when there is no need to distinguish between the information processing apparatuses 10a and 10b, they are referred to as the information processing apparatus 10. Hereinafter, the external devices 20a to 20g are referred to as the external device 20 when it is not necessary to distinguish them. In the following, “first network” is also referred to as “American region”, and “second network” is also referred to as “European region”.

  In the example of FIG. 1, in a first network that provides a service to a user, for example, the US region 51, the information processing apparatus (first information processing apparatus) 10a and the service are provided in cooperation with the information processing apparatus 10a. As the external device (first external device) 20, there are an external device B 20a and an external device C 20b. In the second network, for example, the European region 52, the information processing apparatus (second information processing apparatus) 10b and the external apparatus (second external apparatus) 20 that provides services in cooperation with the information processing apparatus 10b are externally used. A device A20c, an external device B20d, and an external device C20e exist. In the Chinese region 53, the service is not provided to the user, but an external device (third external device) that provides the service in cooperation with the information processing device 10a in the American region 51 and the information processing device 10b in the European region 52. The device 20) includes an external device D20f and an external device B20g.

  The external device A represents an external device that provides the service “A”, the external device B represents an external device that provides the service “B”, and the external device C represents an external device that provides the service “C”. The external device D indicates an external device that provides the service “D”. The service provided by the external device is arbitrary.

  In the following description, when there is no need to distinguish between the external device A 20c, the external devices B 20a, 20d, and 20g, the external devices C 20b and 20e, and the external device D 20f, the external device A, the external device B, the external device C, and the external device D write. Further, when it is not necessary to distinguish the external device A, the external device B, the external device C, and the external device D, they are referred to as the external device 20.

  It should be noted that the information processing apparatus 10a that provides services in the US region 51 and the information processing apparatus 10b that provides services in the European region 52 shown in FIGS. 1 and 2 correspond to the platforms 40a and 40b. Show. Further, the proxies 41a and 41b are hardware and software acting as a proxy when connecting an internal network and an external network. The proxies 41a and 41b have a firewall function.

  In the example of FIG. 1, the external device B 20 a and the external device C 20 b in the American region 51 indicate that they can communicate with the information processing device 10 a and the information processing device 10 b by solid lines. In addition, the external device A20c, the external device B20d, and the external device C20e in the European region 52 indicate that they can communicate with the information processing device 10a and the information processing device 10b by solid lines. In addition, the external device D20f and the external device B20g in the Chinese region 53 indicate that they can communicate with the information processing device 10a and the information processing device 10b by solid lines.

  Here, the user 61 registered in the US region 51 can receive a service provision after transmitting a service request to the information processing apparatus 10a that provides the service in the US region 51 and being authenticated. That is, the user 61 registered in the US region 51 cannot directly send a service request to the information processing apparatus 10b in the European region 52 and have the user authenticated. Similarly, the user 61 registered in the Europe region 52 can receive a service provision after transmitting a service request to the information processing apparatus 10b that provides the service in the Europe region 52 and being authenticated. That is, the user 61 registered in the European region 52 cannot directly send a service request to the information processing apparatus 10a in the American region 51 and have the user authenticated.

  However, for example, in the information processing apparatus 10a, the user 61 registered in the American region 51 is more likely to provide the service in the European region 52 than to provide the service from the external device 20 that provides the service in cooperation with the user 61 In some cases, the access performance is better (the amount of data transfer is large or the data communication speed is faster) when the service is provided from the external device B 20d that provides the service in cooperation with the information processing device 10b. In addition, as shown in FIG. 2, when there is no external device 20 that provides a service in cooperation with the information processing device 10 a in the American region 51, for example, the external device A, the information processing device 10 b in the European region 52 is linked. In some cases, it is desired to provide a service from the external device A20c that provides the service.

Then, as shown in FIG. 2, the information processing apparatus 10a in the US region 51 that has received a transmission request for transmitting a file from the user 61 transmits the file from the result of the measured and shared access performance (data transfer amount). Information on the European region 52 is determined by determining whether the file transmission should be performed from the information processing device 10a in the US region 51 that has received the transmission request to be transmitted, or the file transmission from the information processing device 10b in the European region 52 should be performed. When it is determined that data transfer is faster when the file is transmitted from the processing device 10b, a response is returned to redirect the file transmission request to the information processing device 10b in the European region 52. Thereafter, the user 61 transfers the file to the information processing apparatus 10b in the European region 52 by redirection through the proxy 41a or the like. As described above, in this embodiment, the access performance (data transfer amount) between the information processing apparatuses 10a and 10b in each of the areas 51 and 52 and one or more external apparatuses 20 linked with the information processing apparatuses 10a and 10b is obtained.
