As shown in FIG. 6, there are a method of responding by adding a server according to the load and a method of responding by using a content delivery service to absorb the load.

  In the former method, the Web server a50a is operated, and when an operation state of 100 accesses / second exceeding the capacity of the server is reached, the Web server b50b is added and content distribution is performed by two Web servers. This method is very costly and often falls into a situation where it is not balanced in profit and loss.

  The content delivery service used in the latter method places a cache server, mirror server, etc. close to the user, such as the access part from the network user, and allows the user to distribute content from a server that can be distributed under the best conditions. It is a network service. In the latter method, as described above, since the content is distributed from the cache server of the content delivery service, a load is not applied to the Web server, and it can be handled at a lower cost than the former method.

  The use condition setting unit 21 sets conditions for starting and stopping the use of the content delivery service and stores them in a predetermined memory. As the conditions to be set, for example, a usage period, a suspension period, a threshold value for starting and stopping the usage load, and the like can be considered. The load information collection unit 22 collects log information from the Web server 10 and the content delivery service system 300, and calculates load information and service usage information per unit time. As the calculated load information, for example, Mbps, hit / s, and the like are conceivable.

  The usage control means 23 determines the timing for starting and stopping the use of the content delivery service from the load information calculated by the load information collecting means 22 and the usage conditions set and stored by the usage condition setting means 21, and the execution thereof. I do. The usage fee calculation unit 24 calculates the usage fee of the content delivery service based on the service usage information acquired by the load information collection unit 22.

  The content delivery service system 300 corresponds to the content delivery service system 5 shown in FIG. 1. For example, a plurality of cache servers that hold copies of original content held by a Web server are located close to the user, such as an access part from a network user. It arranges and makes a user distribute copy content from the server which can be distributed on the best conditions.

  The client 500 is a terminal device operated by a network user, is equipped with a Web browser, and requests the Web server 10 to distribute contents via the Internet 200.

  Next, an operation process performed in the hosting service system of this embodiment will be described. FIG. 3 is a sequence diagram showing a flow of the entire operation of the hosting service system of this embodiment (particularly, content delivery service usage control and charge calculation). In the initial state, the content delivery service system is in a suspended state.

  First, in the management server 20, the usage condition setting means 21 sets usage conditions for the content delivery service (S1). Then, content distribution is performed in the Web server 10 (S2), and a log is periodically transmitted to the management server 20 (S3).

  In the management server 50, the load information collecting unit 22 receives the log from the Web server 10 (S4), and calculates the load information of the Web server 10 (S5). Next, the usage control unit 23 determines whether to start using the content delivery service system 300 based on the usage conditions of the content delivery service set in S1 and the load information acquired in S5 (S6). ). The usage control unit 23 determines that the content delivery service should be used when the acquired load information exceeds the set usage condition (load state), and sends a service usage start request to the content delivery service system 300. Transmit (S7).

  The content delivery service system 300 receives a service use start request from the management server 20 (S8), and starts a content delivery service (S9). Thereafter, in response to a content distribution request from the client 500, the copy content corresponding to the request is distributed to the client 500 (S10).

  Then, the Web server 10 periodically transmits a log to the management server 20 (S11), and in the management server 50, the load information collection unit 22 receives the log from the Web server 10 (S12) and calculates load information. (S13). Next, the usage control unit 23 determines whether to start using the content delivery service system 300 based on the set usage conditions and the acquired load information (S14). When the acquired load information falls below the set usage condition (load state), the usage control unit 23 determines that the content delivery service should not be used, and issues a service usage stop request to the content delivery service system 300. (S15).

  The content delivery service system 300 receives a service use stop request from the management server 20 (S16), and stops using the content delivery service (S17). Thereafter, the Web server 10 transmits the log to the management server 20 (S18).

  In the management server 20, the load information collection unit 22 receives the log from the content delivery service system 300 (S19), and acquires the usage information of the content delivery service (S20). Then, the usage fee calculation means 24 calculates a usage fee for the content delivery service based on the acquired service usage information (S21).

  Next, usage control of the content delivery service in the present embodiment will be described using a specific example. As shown in FIG. 4A, the usage condition setting means 21 sets the usage period of the content delivery service from March 1 to March 6, 2009, a threshold value for starting use of 2.5 Mbps, a threshold value for stopping use. Assume that 0 Mbps is set. Further, as shown in FIG. 4B, the load information of the Web server 10 in March 2009 is as follows. The load dropped below 2.0 Mbps on March 5 from the high load at the beginning of the month. And the load exceeds 2.5 Mbps.

  On March 1st, according to the usage period condition March 1st to March 6th, the usage control means 23 determines the start of content delivery service use on March 1st, and the content delivery service system 300 is serviced. Request start of use. Next, when the load information collection unit 22 calculates the load information 2.0 Mbps on March 5, the usage control unit 23 determines the content delivery service from the usage stop threshold 2.0 Mbps set by the usage condition setting unit 21. The use stop is determined, and a service use stop request is made to the content delivery service system 300. Finally, when the load information collection unit 22 calculates the load information 2.5 Mbps on March 31, the usage control unit 23 uses the usage start threshold (2.0 Mbps) and the usage period set by the usage condition setting unit 21. With reference to the conditions (March 1 to March 6), it is determined that the content delivery service should not be used, and the service use start request is not performed.

  Next, the effect in this embodiment is demonstrated with reference to FIG. FIG. 5 is a comparison of monthly usage charges when the load on the Web server 10 exceeds 3 Mbps in terms of Web server expansion, content delivery service usage, and content delivery service usage control of this embodiment. For simplicity of explanation, it is assumed that the load exceeds 3.0 Mbps and does not decrease at the timing shown in the figure.

  Assuming that the server usage fee is ¥ 100,000 / unit, in the case of server expansion, the fee for the two servers is ¥ 200,000 regardless of the load. When the content delivery service 300 is used, the usage fee for the content delivery service 300 is added to the fee for one server according to the usage amount.

  In the case of the content delivery service usage control according to the present embodiment, the configuration is such that the usage start / stop of use of the content delivery service 300 is controlled according to the load. Therefore, until the Web server 10 exceeds the capacity of one device. After the usage fee for one server is exceeded, the usage fee for the content delivery service 300 is added according to the usage amount. Here, it is assumed that the load threshold for starting to use the content is 3.0 Mbps.

  In this way, by controlling the use of the content delivery service as in this embodiment, there is no need for enormous server expansion costs, and there is no need to burden the user with unnecessary use costs for the content delivery service. It is possible to cope with the deterioration of server service provision performance and system down at a reasonable cost.
