Detailed Description

Next, embodiments of the present disclosure will be described in detail with reference to the drawings.

Fig. 1 is a diagram showing a system configuration of an information processing system according to an embodiment of the present disclosure.

As shown in fig. 1, an information processing system 50 according to an embodiment of the present disclosure is configured by service providing apparatuses 10A and 10B, and is configured by mutually connecting terminal apparatuses 40A and 40B functioning as client terminals via a network 30 such as the internet.

The service providing apparatus 10A is an information processing apparatus for company a that provides services to users of company a. The service providing apparatus 10B is an information processing apparatus for company B that provides a service to a user of company B.

The services provided by the service providing apparatuses 10A and 10B include services that perform various processes such as an OCR (Optical Character Reading) process, a translation process, a save process, an expense adjustment process, and an image conversion process. Further, the service providing apparatuses 10A and 10B can execute various processes in cooperation with other service providing apparatuses, instead of providing services individually.

The user of company a accesses the service providing apparatus 10A via the terminal apparatus 40A as a client apparatus to use the service provided by company a, and the user of company B accesses the service providing apparatus 10B via the terminal apparatus 40B to use the service provided by company B.

Here, in general, in the service providing apparatus as described above, when a version upgrade of a system, a change of software, or the like is performed, it is necessary to evaluate whether or not a problem or the like occurs after the start of the service before the start of the service.

In addition, the service providing apparatuses 10A and 10B that are currently providing services start providing services after confirming that such evaluation has been performed and no problem has occurred. That is, the service providing apparatuses 10A and 10B in operation are evaluated information processing apparatuses.

In the following description, a case will be described in which the service providing apparatus 10B for company B that has been evaluated is replaced with the service providing apparatus 20B for company B that has not yet been evaluated as described above.

The service providing apparatus 20B is an apparatus in which a version upgrade of a system, a change of software, and the like are performed with respect to the service providing apparatus 10B, and is described assuming that an unexcited state for confirming an evaluation that a problem does not occur in an actual operation is not completed.

Next, fig. 2 shows a hardware configuration of the service providing apparatuses 10A, 10B, and 20B.

As shown in fig. 2, the service providing apparatuses 10A, 10B, and 20B each include a CPU11, a memory 12, a storage device 13 such as a Hard Disk Drive (HDD), a communication Interface (IF)14 for transmitting and receiving data to and from an external apparatus or the like via a network 30, and a User Interface (UI) device 15 including a touch panel, a liquid crystal display, and a keyboard. These components are connected to each other via a control bus 16.

The CPU11 executes predetermined processing in accordance with a control program stored in the memory 12 or the storage device 13, and controls the operation of the service providing devices 10A, 10B, and 20B. In the present embodiment, the CPU11 is described as reading out and executing the control program stored in the memory 12 or the storage device 13, but the program may be stored in a storage medium such as a CD-ROM and supplied to the CPU 11.

Fig. 3 is a block diagram showing a functional configuration of an information processing system including the service providing apparatuses 10A and 10B realized by executing the control program described above. Fig. 3 shows a configuration example in the case of operating with 2 service providing apparatuses 10A and 10B that have been evaluated, and the service providing apparatus 20B is not shown, but the service providing apparatus 20B also has the same functional configuration as the service providing apparatuses 10A and 10B.

As shown in fig. 3, the information processing system 50 according to the present embodiment includes: a service providing apparatus 10A for company a; a service providing apparatus 10B for company B; and a common processing request storage section 61.

The service providing apparatus 10A for company a executes processing in response to the processing request received from the terminal apparatus 40A, and returns the processing result to the terminal apparatus 40A. The service providing apparatus 10B for company B executes processing in response to the processing request received from the terminal apparatus 40B, and returns the processing result to the terminal apparatus 40B.

The service providing apparatus 10A includes a processing request receiving unit 71, a processing result storage unit 72, and a common processing execution unit 73.

Similarly, the service providing apparatus 10B includes a processing request receiving unit 81, a processing result storage unit 82, and a common processing execution unit 83.

The common processing execution unit 73 includes a plurality of virtual machines 76 and a control unit 77 that controls the number of activated virtual machines 76 and the overall operation of the common processing execution unit 73. Similarly, the common processing execution unit 83 includes a plurality of virtual machines 86 and a control unit 87 that controls the number of activated virtual machines 86 and the operation of the common processing execution unit 83 as a whole.

Here, the virtual machine refers to a computer virtually or virtually created within 1 physical computer. By using such a virtual machine technique, a plurality of virtual machines can be configured in a physical machine such as a server or a device configured by 1 computer, and each virtual machine can process in parallel. In addition, the virtual machine is also sometimes referred to as an instance (instance).

The process of controlling the number of virtual machines to be started in accordance with the amount of processing to be executed is called auto scaling (AutoScale). By performing this automatic scaling, when the amount of processing to be executed is large, the scaling (scale out) is performed as control for increasing the number of virtual machines to be started, and when the amount of processing to be executed is small, the scaling (scale in) is performed as control for decreasing the number of virtual machines to be started.

As described above, the service providing apparatus 10A is an information processing apparatus that processes a processing request received from the terminal apparatus 40A as a client apparatus using a virtual machine that has been started. The service providing apparatus 10B is an information processing apparatus that processes a processing request received from the terminal apparatus 40B as a client apparatus using the activated virtual machine.

Here, the service providing apparatuses 10A and 10B are configured to be capable of configuring a virtual machine that executes different processes in each apparatus and a virtual machine that executes common processes in 2 apparatuses.

Hereinafter, a processing request that can be processed by any of the 2 service providing apparatuses 10A and 10B is referred to as a common processing request, and a processing request that can be processed only by any of the 2 service providing apparatuses 10A and 10B is referred to as an individual processing request. In the 2 service providing apparatuses 10A and 10B, the virtual machines capable of processing the common processing request are referred to as common virtual machines, and the virtual machines capable of processing the individual processing request are referred to as individual virtual machines. In fig. 3, for the sake of simplicity of explanation, only the configuration in the case of processing a common processing request using a common virtual machine will be described.

Then, the common processing request storage unit 61 stores, in the form of a queue (queue), processing requests that can be processed by any of the 2 service providing apparatuses 10A, 10B among the processing requests received by the 2 service providing apparatuses 10A, 10B, respectively.

Next, the functional configuration of each of the service providing apparatuses 10A and 10B will be described.

First, the configuration of the service providing apparatus 10A will be described.

The processing request accepting unit 71 accepts a processing request from the terminal device 40A, and stores the accepted processing request in the common processing request storage unit 61 in the form of a queue. The processing request accepting unit 71 acquires the processing result of the accepted processing request from the processing result storage unit 72, and returns the processing result to the terminal device 40A.

The processing result storage section 72 stores a processing result obtained by executing the processing request at the common processing execution section 73. When the common process execution unit 83 executes the process request received by the present apparatus, the process result storage unit 72 receives the process result from the common process execution unit 83 and stores the received process result.

The common processing execution unit 73 is configured to be able to start up a plurality of virtual machines 76, and the control unit 77 controls the number of virtual machines 76 that are started up, and the common processing request stored in the common processing request storage unit 61 is executed by the virtual machine 76 that has started up.

Then, the common process execution unit 73 stores the process result of the common process request received by the own device in the process result storage unit 72 of the own device, and transfers the process result of the common process request received by the service providing device 10B to the process result storage unit 82 of the service providing device 10B.

The processing request accepting unit 81, the processing result storage unit 82, and the common processing executing unit 83 in the service providing apparatus 10B perform the same operations as the processing request accepting unit 71, the processing result storage unit 72, and the common processing executing unit 73 in the service providing apparatus 10A, respectively, and therefore detailed description thereof is omitted.

With such a configuration, in the information processing system 50 according to the present embodiment, the common process execution unit 83 of the service providing apparatus 10B may execute the process request received by the service providing apparatus 10A from the terminal apparatus 40A, or the common process execution unit 73 of the service providing apparatus 10A may execute the process request received by the service providing apparatus 10B from the terminal apparatus 40B.

Next, a case will be described in which the service providing apparatus 10B in operation is replaced with the service providing apparatus 20B that has not been evaluated in a state operated with such a configuration.

Here, in a case where the service providing apparatus 10B is replaced with the service providing apparatus 20B without stopping the provision of the service to company B, a replacement method called blue-green deployment is used.

The cyan deployment refers to a replacement method of replacing an evaluated information processing apparatus with an information processing apparatus in operation after updating and evaluating any one of a plurality of information processing apparatuses. According to this blue-green deployment, it is possible to replace an evaluated information processing apparatus with an information processing apparatus in operation without interrupting the service being provided.

A specific alternative to such a blue-green deployment is illustrated with reference to fig. 4.

The system example shown in fig. 4 has the following structure: the client apparatus 100 transmits a processing request to the server apparatus 101, executes the processing of the processing request in the server apparatus 101, and returns the processing result to the client apparatus 100.

In such a system configuration, the server apparatus 101 currently operating to provide a service to the client apparatus 100 is an evaluated apparatus in which it is confirmed that no problem has occurred by the evaluation as described above.

Here, as shown in fig. 4 (a), a case will be described in which the server apparatus 101 operates with the software of version 1 and updates the software to version 2. In such a case, if the software of the server apparatus 101 is suddenly updated to version 2, some problems may occur. Therefore, as shown in fig. 4 (a), a device in which the software of version 2 is installed in the server device 102 having the same hardware configuration as that of the server device 101 is prepared. Of course, the server apparatus 102 is not evaluated and is in an unevaluated state.

Then, as shown in fig. 4 (B), in a state where the server apparatus 101 provides a service, the server apparatus 102 is operated, and various processes are executed using other client apparatuses, whereby whether or not there is a problem in the software of version 2 is evaluated. Here, a case will be described in which the evaluation of the server apparatus 102 is completed without any problem.

Therefore, as shown in fig. 4 (C), the server apparatus 101 and the server apparatus 102 are replaced, the server apparatus 102 is set to the operating state, and the server apparatus 101 is set to the non-operating state.

By performing such replacement, the software version upgrade of the server apparatus is performed without interrupting the provision of the service to the client apparatus 101.

A problem arises if only the replacement method based on such blue-green deployment is applied when replacing the evaluated service providing apparatus 10B with the non-evaluated service providing apparatus 20B in the system configured as shown in fig. 3.

Specifically, a state in which only the service providing apparatus 20B that has not been evaluated is operated with respect to the system having the configuration shown in fig. 3 will be described with reference to fig. 5.

Fig. 5 shows a configuration in which an unevaluated service providing apparatus 20B is added to a configuration in which evaluated service providing apparatuses 10A and 10B are operating and services are provided to terminal apparatuses 40A and 40B, respectively.

The terminal device 40C is a device for evaluating the service providing device 20B. The terminal device 40C transmits a processing request for evaluation for confirming whether or not there is a problem with the operation of the software or the like to be updated to the service providing device 20B, and evaluates the operation by confirming the processing result.

However, in the information processing system according to the present embodiment, the common processing request that can be processed by any one of the devices is temporarily stored in the common processing request storage unit 61, and is processed by the service providing device that can execute the processing.

Therefore, for example, there is a possibility that a processing request transmitted from the terminal device 40A to the service providing device 10A is stored in the common processing request storage unit 61 and then processed by the service providing device 20B that is not evaluated. Here, when there is some trouble in the software or the like of the service providing apparatus 20B, the trouble occurs when the processing request transmitted from the terminal apparatus 40A is executed, and an accurate processing result cannot be obtained.

Therefore, as shown in fig. 6, the information processing system according to the present embodiment is provided with an evaluation state management unit 62.

The evaluation state management unit 62 functions as a registration means for registering whether each of the service providing apparatuses 10A, 10B, and 20B, which are a plurality of information processing apparatuses, is not evaluated or is evaluated.

Fig. 7 shows a functional configuration of the information processing system according to the present embodiment in which the evaluation state management unit 62 is provided.

Although the functional configuration of the service providing apparatus 20B is not shown in fig. 7, the same functional configuration as that of the service providing apparatuses 10A and 10B is provided. In fig. 7, for the sake of simplifying the description, a line indicating that the common process executing units 73 and 83 store the process results in the process result storage unit of the service providing apparatus 20B or a line indicating that the common process executing unit of the service providing apparatus 20B stores the process results in the process result storage units 72 and 82 of the service providing apparatuses 10A and 10B is omitted.

Next, an evaluation state management table showing the evaluation states of the service providing apparatuses 10A, 10B, and 20B registered in the evaluation state management unit 62 will be described.

First, in the present embodiment, a description will be given assuming that the service providing apparatuses 10A, 10B, and 20B correspond to the apparatus IDs shown in fig. 8, respectively. Specifically, the service providing apparatus 10A corresponds to "10001" as the apparatus ID, the service providing apparatus 10B corresponds to "10002" as the apparatus ID, and the service providing apparatus 20B corresponds to "10003" as the apparatus ID.

Fig. 9 shows an example of the evaluation state management table managed by the evaluation state management unit 62. In the evaluation state management table shown in fig. 9, the service providing apparatus is specified by the apparatus ID corresponding to the evaluation state of the service providing apparatus of the apparatus ID. Here, the service providing apparatuses 10A, 10B are registered as "evaluated", and the service providing apparatus 20B is registered as "unevaluated".

Here, the non-evaluation means a state in which evaluation is not completed, and the non-evaluation state includes a state during evaluation or a state before evaluation.

Further, the evaluated state means that the evaluation is completed and no problem is confirmed by the evaluation. The evaluated state includes an operating state and a non-operating state.

The operation state means a state in which the service of receiving a processing request from the client terminal apparatus and processing the request is currently being provided. That is, the operation means that the apparatus is evaluated. However, even the evaluated device may be in a non-operating state in which it is not currently operating.

Then, the common processing request storage unit 61 stores, in a queue, processing requests that can be processed by any of the 3 service providing apparatuses 10A, 10B, and 20B among the processing requests received by the 3 service providing apparatuses 10A, 10B, and 20B, respectively, together with information indicating which of the 3 service providing apparatuses 10A, 10B, and 20B is to be processed.

Fig. 10 shows a specific example of the case where the common processing request storage unit 61 stores the common processing request.

As shown in fig. 10, the common processing request storage unit 61 stores the reception date and time at which the common processing request is received from the terminal device 40A, 40B, or 40C in association with the request ID for specifying the common processing request and the reception device ID for specifying the service providing device that has received the common processing request.

For example, it is known that the common processing request having the request ID "201111" is received in the service providing device 10B having the device ID "10002" at 18 o' clock 3/6/3 in 2019.

Then, the control units 77 and 87 in the service providing apparatuses 10A and 10B and the control unit in the service providing apparatus 20B respectively control as follows: when the own device is registered as evaluated in the evaluation state management unit 62, only the processing request from the evaluated service providing device among the processing requests stored in the common processing request storage unit 61 is acquired and processed, and when the own device is registered as not evaluated in the evaluation state management unit 62, only the processing request from the own device among the processing requests stored in the common processing request storage unit 61 is acquired and processed.

By performing such control, the processing request transmitted from the terminal device 40A or 40B is processed in either of the service providing devices 10A or 10B, and the processing request transmitted from the terminal device 40C is processed in the service providing device 20B. That is, the processing requests transmitted from the terminal apparatuses 40A and 40B are prevented from being processed in the service providing apparatus 20B that is not evaluated.

The control units 77 and 87 in the service providing apparatuses 10A and 10B and the control unit in the service providing apparatus 20B control the number of activated common virtual machines in the own apparatus in accordance with the state of the processing request from the evaluated service providing apparatus among the processing requests stored in the common processing request storage unit 61 when the own apparatus is registered as evaluated in the evaluation state management unit 62, and control the number of activated common virtual machines in the own apparatus in accordance with the state of the processing request from the own apparatus among the processing requests stored in the common processing request storage unit 61 when the own apparatus is registered as not evaluated in the evaluation state management unit 62.

That is, the control units 77 and 87 of the service providing apparatuses 10A and 10B each execute automatic scaling for increasing or decreasing the number of activated common virtual machines in the own apparatus in accordance with the state of the common processing request received by any one of the service providing apparatuses 10A and 10B among the common processing requests stored in the common processing request storage unit 61. Then, the control of the service providing apparatus 20B executes automatic scaling in accordance with the state of the common processing request received in the own apparatus among the common processing requests stored in the common processing request storage section 61.

Next, the operation of the information processing system according to the present embodiment will be described with reference to the flowchart of fig. 11.

The control units 77 and 87 of the service providing apparatuses 10A and 10B and the control unit of the service providing apparatus 20B refer to the evaluation state management unit 62 in step S101 to determine whether the own apparatus is an evaluated apparatus or an unevaluated apparatus.

Then, when it is determined in step S101 that the own device is an evaluated device, the control unit acquires, in step S102, a common processing request that the evaluated device becomes a recipient device among the common processing requests stored in the common processing request storage unit 61.

When it is determined in step S101 that the own device is an unexcited device, the control unit acquires, in step S103, a common processing request of the own device, which is a recipient device, among the common processing requests stored in the common processing request storage unit 61.

Then, the control unit executes the processing of the acquired common processing request in step S104, and stores the processing result in a predetermined result storage unit in step S105.

In the service providing apparatuses 10A, 10B, and 20B according to the present embodiment, the common processing execution units perform automatic scaling for controlling the number of virtual machines to be started.

Then, in a state where the common processing request is received by either of the service providing apparatuses 10A and 10B, if the virtual machines 76 and 86 are independently activated and the processes are executed by the common processing execution units 73 and 83 of the service providing apparatuses 10A and 10B, respectively, there is a possibility that more than necessary number of virtual machines are activated.

Therefore, the information processing system according to the present embodiment may further include an automatic scaling switching control unit 63 for selecting a service providing device that starts the common virtual machine and processes the common processing request.

Fig. 12 shows a configuration of the information processing system according to the present embodiment in the case where the automatic scaling switching control unit 63 is provided in this manner. Note that, for simplification of explanation, the service providing apparatus 20B and the terminal apparatus 40C are not shown in fig. 12.

Fig. 12 shows a configuration in which the automatic scaling switching control unit 63 is provided for the functional block diagram shown in fig. 7, and processing for executing individual processing requests is provided in the service providing apparatuses 10A and 10B.

Specifically, the service providing apparatus 10A is provided with an individual process executing unit 74 and an individual process request storage unit 75, and the service providing apparatus 10B is provided with an individual process executing unit 84 and an individual process request storage unit 85.

The automatic scaling switching control unit 63 controls the number of activated common virtual machines in the 2 service providing apparatuses 10A and 10B in accordance with the state of the processing request stored in the common processing request storage unit 61.

For example, the automatic scaling switching control unit 63 controls the number of activated common virtual machines based on the storage amount of the processing request stored in the common processing request storage unit 61, the storage time that is the time from the time when the processing request is stored to the present time, and the like.

Then, the automatic scaling switching control unit 63 selects any one of the plurality of service providing apparatuses that has been evaluated, and instructs the control unit of the selected service providing apparatus to acquire and process the processing request from the evaluated service providing apparatus among the processing requests stored in the common processing request storage unit 61.

Here, since the service providing apparatuses 10A and 10B are evaluated service providing apparatuses when referring to the information in the evaluation state management unit 62, the automatic scaling switching control unit 63 selects one of the 2 service providing apparatuses 10A and 10B and controls the number of activated common virtual machines in the selected service providing apparatus when controlling the number of activated common virtual machines in the service providing apparatuses 10A and 10B.

Specifically, the automatic scaling switching control unit 63 instructs the control unit of the selected service providing apparatus to set the number of activated common virtual machines in the unselected service providing apparatuses of the 2 service providing apparatuses 10A and 10B to a fixed value, for example, 0.

In the configuration shown in fig. 12, the control unit 77 executes automatic scaling processing for controlling the number of activated virtual machines 76 under the control of the automatic scaling switching control unit 63.

The individual process execution unit 74 is configured to be able to start a plurality of virtual machines in the same manner as the common process execution unit 73, and controls the number of virtual machines to be started by a control unit (not shown), and executes the process of the individual process request stored in the individual process request storage unit 75 by the virtual machine that is started.

The individual processing request storage unit 75 stores, in a queue, individual processing requests that can be processed only by the service providing device 10A among the processing requests received by the processing request reception unit 71.

The individual process execution unit 84 and the individual process request storage unit 85 in the service providing apparatus 10B perform the same operations as the individual process execution unit 74 and the individual process request storage unit 75 in the service providing apparatus 10A, respectively, and therefore, detailed description thereof is omitted.

Then, the processing result storage section 72 stores not only the processing result from the common processing execution section 73 but also the processing result obtained by executing the individual processing request at the individual processing execution section 74.

Next, the detailed configuration of the automatic expansion/contraction switching control section 63 shown in fig. 12 will be described with reference to fig. 13.

As shown in fig. 13, the automatic scaling switching control unit 63 includes a scaling instruction unit 91, a processing request monitoring unit 92, an automatic scaling device selection unit 93, and a device information storage unit 94.

The processing request monitoring unit 92 periodically monitors, for example, the common processing request stored in the common processing request storage unit 61, and transmits the monitoring result to the scaling instruction unit 91.

The scaling instruction unit 91 determines whether or not automatic scaling is necessary based on the monitoring result in the processing request monitoring unit 92, and instructs the control unit 77 of the service providing apparatus 10A or the control unit 87 of the service providing apparatus 10B to perform automatic scaling when it is determined that automatic scaling is necessary.

In this case, the scaling instruction section 91 instructs only the service providing apparatuses selected by the automatic scaling implementation apparatus selection section 93 to perform automatic scaling, and instructs the service providing apparatuses not selected not to perform automatic scaling or to perform scaling so that the number of starts is 0.

The following is shown in fig. 13: the scaling instruction unit 91 selects the service providing device 10A as a device to be automatically scaled, instructs the control unit 77 to automatically scale, and instructs the control unit 87 to scale the number of virtual machines to 0.

The automatic scaling device selection unit 93 selects which device of the service providing devices 10A and 10B is to be set as the device to be automatically scaled, using the device information stored in the device information storage unit 94, that is, the attribute information on each of the 2 service providing devices 10A and 10B.

The device information storage unit 94 stores, as device information, attribute information such as the current number of activated common virtual machines in the service providing devices 10A and 10B, the date and time of creation of each of the service providing devices 10A and 10B, and the processing results of the common processing requests of the service providing devices 10A and 10B.

Then, the automatic scaling device selection unit 93 may select, for example, the service providing device having the largest number of currently-started common virtual machines as the device to be automatically scaled, with reference to the device information in the device information storage unit 94.

Alternatively, the automatic scaling device selection unit 93 may refer to the device information in the device information storage unit 94 to select, as the device to be automatically scaled, the device with the longest date and time of creation from among the service providing devices 10A and 10B.

The automatic scaling device selection unit 93 may refer to the device information in the device information storage unit 94 to select, as the device to be automatically scaled, one of the service providing devices 10A and 10B having a history of processing requests received in the past.

Fig. 14 shows an example of the device information stored in the device information storage unit 94.

As shown in fig. 14, the device information storage unit 94 stores information such as a device ID, a type of a processing request that can be processed, destination information of the processing request storage unit, destination information of the control unit that performs automatic scaling, a creation date and time, and the number of virtual machines currently being started, in the form of a table.

The automatic scaling device selection unit 93 can acquire information such as the creation date and time of the service providing devices 10A and 10B and the number of activated common virtual machines currently activated in each device by referring to such device information, and can select a device to be automatically scaled.
