Description

  The present invention relates to a service construction system in a distributed computing environment.

  In recent years, service forms in which a plurality of applications are linked and provided as one service have become common. Such a service form is exemplified by a business application in a company. In such a service form, a system form in which each application is operated on a single IT resource can be considered.

  Here, the IT resource refers to general computing resources exemplified by a general-purpose PC (Personal Computer), a general-purpose server, and an engine that accelerates a specific process such as GPGPU (General Purpose Graphics Processing Unit). Further, not only physical computing resources but also resources virtualized by a technology such as a virtual machine are included.

  On the other hand, recently, a system form using a distributed computing environment has become mainstream. A distributed computing environment uses a plurality of IT resources interconnected by a communication network (hereinafter referred to as a network) to operate each application for constructing a service on different IT resources.

  When constructing such a service, the service designer first determines the necessary functions and determines how each function works. Then, the service designer determines a specific application for realizing each function.

  However, only the cooperation of functions (applications) executed on IT resources is determined by such a procedure. Therefore, a network that connects IT resources is not considered.

  At present, there is an example in which the function is processed on the IT resource even if the process is functionally performed on the network resource. That is, there is an example in which IT resources are used as network resources. As described above, the resource to be processed has no boundary.

  Here, the network resources refer to all network device resources exemplified by network routers (hereinafter referred to as routers), network switches (hereinafter referred to as switches), firewalls, and load distribution devices. It also includes not only physical network resources, but also resources that are exemplified or virtualized by virtual routers and virtual firewalls.

  Examples of causing the processing performed on the network resource to be performed on the IT resource include iptables (Non-patent Document 1) and Click Module Router (Non-patent Document 2). iptables is an application that provides a firewall function. Click Module Router is a software router.

  When such software is executed on a general-purpose server, the performance is generally lower than that of a dedicated network device such as a router or a firewall. However, dedicated network devices are often more expensive than general-purpose servers. Therefore, there is a merit that the service can be realized at low cost by executing the above-described software on the general-purpose server instead of using the dedicated network device.

  In such service construction, it is required to shorten the period from service design to release. Therefore, when service design information is input, a mechanism for automatically mapping applications to IT resources and setting to network resources is required. The following technologies are disclosed as related technologies.

  Patent Document 1 discloses a system layout design apparatus that can automatically generate an efficient system configuration. The system layout design apparatus of Patent Literature 1 is a system layout design apparatus that determines the arrangement of a plurality of functions on a management target network.

  According to the system layout design apparatus of Patent Document 1, the generated system layout is evaluated, and the system layout having the highest evaluation is used as a design result. Therefore, even in a large-scale managed network, the efficiency is improved. It is possible to design a system layout that best suits a predetermined evaluation standard related to sex and the like.

  Patent Document 2 discloses a network system in which each node constituting a network transmits physical information and an identifier of the own node to a server node when a network configuration setting parameter is generated. The network system of Patent Document 2 is a network system having a server node and a node managed by the server node.

  According to the network system of Patent Document 2, the latest physical configuration information and identification of each node can be automatically collected. This eliminates the need for the network system administrator to know detailed information about each node.

  Further, Patent Document 3 discloses an application flow control device that realizes application cooperation processing based on a flow without going through a specific management server. The application flow control device disclosed in Patent Literature 3 is an application flow control device having a part of a plurality of applications that perform cooperation processing.

  According to the application flow control apparatus of Patent Document 3, since a message for flow control is transferred between apparatuses having an application, application cooperation processing based on a flow is realized without going through a specific management server. Is done.

  In addition, Patent Document 4 discloses a more flexible and advanced distributed processing than a simple load distribution system for a conventional WWW server, that is, efficient computer resources, networks that connect computer resources, network connection devices, and the like. A distributed processing system capable of executing an allocation process is disclosed. Patent Document 5 discloses an information processing apparatus that can use various functions according to the capabilities of a plurality of devices connected to a network. U.S. Patent No. 6,057,031 discloses an architecture for a distributed computing system.

  In the system layout design apparatus of Patent Document 1, the system layout is generated only for IT resources, not for network resources. Therefore, when building a service, it is necessary to separately set network resources, and it takes time until the service is released.

  In addition, the network system disclosed in Patent Document 2 can automate setting to network resources, but does not perform mapping of applications to IT resources. Therefore, it is necessary to perform application mapping separately, and it takes time to release the service.

  The application flow control apparatus of Patent Document 3 is limited to the process in which information shown in each activity is executed on IT resources, and does not consider network resources. For this reason, in the cooperation of applications, optimal network settings may not be made, and service performance may deteriorate.

  A service construction system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

(First embodiment)
First, the service construction system according to the first embodiment of the present invention will be described below.

[Description of configuration]
First, the configuration of the service construction system in this embodiment will be described. FIG. 1 is a diagram showing a configuration of a service construction system in the present embodiment. The service construction system of this embodiment includes a distributed computing environment 1 and a service construction device 2.

  First, the distributed computing environment 1 will be described. The distributed computing environment 1 includes one or more network resources 11 and one or more IT resources 12.

  First, the network resource 11 refers to all network device resources exemplified by network routers (hereinafter referred to as routers), network switches (hereinafter referred to as switches), firewalls, and load balancers. The network resource 11 includes not only a physical network resource but also a resource exemplified or virtualized by a virtual router or a virtual firewall.

  Next, the IT resource 12 indicates a general computing resource exemplified by a general-purpose PC (Personal Computer), a general-purpose server, and an engine that accelerates a specific process such as GPGPU (General Purpose Graphics Processing Unit). The IT resource 12 includes not only a physical calculation resource but also a resource virtualized by a technology such as a virtual machine.

  Network resources 11 are connected to each other to form a network. The IT resource 12 is connected to the network resource 11. The network resource 11 and the IT resource 12 are set by the service construction device 2 with setting information for constructing a service. Hereinafter, the network resource 11 and the IT resource 12 are collectively referred to as distributed computing resources.

  Next, the service construction device 2 will be described. FIG. 2 is a diagram showing a configuration of the service construction device 2 in the present embodiment. The service construction device 2 in this embodiment includes a storage unit 100, a control unit 120, a communication unit 130, an input unit 140, and an output unit 150. The storage unit 100, the control unit 120, the communication unit 130, the input unit 140, and the output unit 150 are connected via a bus 160 and can transmit and receive data.

  First, the communication unit 130 is a communication interface with an external device. The communication unit 130 is exemplified by a NIC (Network Interface Card). The service construction device 2 can transmit and receive data to and from the network resource 11 and the IT resource 12 via the communication unit 130.

  Next, the input unit 140 and the output unit 150 are input / output interfaces with the user of the service construction device 2. The input unit 140 is exemplified by a keyboard and a mouse. The output unit 150 is exemplified by an LCD (Liquid Crystal Display). The user can operate the service construction device 2 using the input unit 140 and the output unit 150.

  Next, the memory | storage part 100 memorize | stores the computer program and data which implement | achieve the function of the service construction apparatus 2. FIG. The storage unit 100 includes a main storage device and a secondary storage device such as a RAM (Random Access Memory), a ROM (Read Only Memory), and an HDD (Hard Disk Drive). The storage unit 100 includes a service construction program 110 as a computer program.

  Next, the control unit 120 executes the computer program stored in the storage unit 100 to realize the function of the service construction device 2. The control unit 120 is exemplified by a CPU (Central Processing Unit).

  Here, the service construction program 110 stored in the storage unit 100 can be recorded in a removable storage medium. Examples of the storage medium include a CD (Compact Disk) and a flash memory (USB memory) equipped with a USB (Universal Serial Bus) interface. The service construction program 110 can be distributed using such a recording medium.

  The service construction program 110 is introduced into the service construction apparatus 2 via a CD drive or a USB interface of the service construction apparatus 2 (not shown). The service construction program 110 may be stored in a downloadable form on the HDD of an application server connected to a network (not shown). In this case, the service construction program 110 is introduced into the service construction device 2 via the network.

  Next, FIG. 3 is a functional block diagram showing functions of the service construction device 2 in the present embodiment. The service construction device 2 of this embodiment includes an application flow analysis unit 21, a mapping information generation unit 22, an application management unit 23, a setting instruction unit 24, and a resource management unit 25. Here, each functional block of the service construction device 2 may be realized by software as described above, or may be realized by hardware. Alternatively, it may be realized by a combination of software and hardware. Hereinafter, each functional block of the service construction device 2 will be described in detail.

  First, the application flow analysis unit 21 analyzes the connection relationship of each process constituting the service indicated by the service definition 42. The application flow analysis unit 21 receives the service definition 42 as an input. The application flow analysis unit 21 analyzes the connection relationship of each process constituting the service indicated by the service definition 42 and generates an application flow analysis result. The application flow analysis unit 21 outputs the application flow analysis result to the mapping information generation unit 22.

  Here, the service definition 42 is input by a service designer who is a user of the service construction device 2. The service definition 42 includes information such as the contents of processes included in the designed service, the order in which the processes are executed, and the input / output format of the processes.

  The connection relationship of each process analyzed by the application flow analysis unit 21 indicates an input / output relationship between the processes. In other words, the connection relationship includes information such as which process output is a certain process output or which process output is a certain process input.

  The service definition 42 is not limited to a specific definition method as long as the above information is included. An example of the service definition 42 is BPEL (Business Process Execution Language) which is a business process modeling language. The BPEL can call a Web service in a predetermined procedure by describing an instruction expressing each processing step called an activity.

  Further, the service definition 42 may include service restrictions in the information. A service restriction is, for example, a condition that must be satisfied in mapping a service to a distributed computing resource. In other words, service restrictions include overall service throughput, processing performance when executing certain processes, network delays between certain processes, power consumption required to operate the service, or usage Including conditions such as priorities of distributed computing resources to be performed. Note that the mapping is a generic name including setting to distributed computing resources and arrangement of applications to the distributed computing resources.

  Next, the application management unit 23 stores application information that can be executed in the distributed computing environment. The application management unit 23 registers the application 43 from the outside by the user. Here, the application 43 is not limited to a computer program that provides some function. For example, hardware setting information that can change the hardware configuration such as FPGA (Field Programmable Gate Array) is also included.

  The application information includes information such as what functions each application has, what input / outputs are required, and what conditions are required for use. Conditions for use include, for example, performance conditions such as CPU operating frequency and main memory capacity, functions to be provided with hardware, OS (Operating System) types and versions, and required libraries. This is an environmental condition. For example, in the case of an application premised on the use of GPGPU, it is conceivable that the GPU is provided as hardware for execution, or that a library dedicated to GPGPU is provided.

  Next, the resource management unit 25 stores resource information related to distributed computing resources included in the distributed computing environment 1. For example, if the resource information is IT resource 12, the performance of the installed CPU, the memory capacity, the disk capacity, the communication speed of the network interface, the installed expansion card, the MAC (Media Access Control) address, IP ( Internet Protocol) includes information such as address, netmask, and power consumption. Further, for example, in the case of the network resource 11, the resource information includes information such as a link communication speed, a MAC address, an IP address, a netmask, and various power consumptions in each physical port. In addition, by connecting a monitoring device to the resource management unit 25, it is possible to monitor the state of the distributed computing resource.

  The resource management unit 25 inputs state information 44 from the distributed computing resource. The resource management unit 25 changes the stored resource information based on the state information 45 when a configuration change including addition or deletion of the distributed computing resource of the distributed computing environment 1 occurs.

  Next, the mapping information generation unit 22 generates mapping information that is setting information for mapping the service to the distributed computing resource. The mapping information generation unit 22 inputs an application flow analysis result from the application flow analysis unit 21. Further, the mapping information generation unit 22 acquires application information from the application management unit 23 and resource information from the resource management unit 25. The mapping information generation unit 22 generates mapping information based on the application flow analysis result, application information, and resource information.

  Specifically, the mapping information generation unit 22 selects an application that realizes each process included in the application flow analysis result from the applications stored in the application management unit 23 while referring to the resource information. The mapping information generation unit 22 selects, for example, an IT resource having sufficient calculation performance for executing a certain application, or operates an application executed on a network resource such as a firewall on the IT resource. Make a selection. The mapping information generation unit 22 stores the result selected in this way as mapping information.

  When the mapping information generation unit 22 selects an application and a distributed computing resource that operates the application, the mapping information generation unit 22 determines a communication path between the applications based on the application flow analysis result. When the mapping information generation unit 22 determines a communication path between applications, the mapping information generation unit 22 generates setting information of distributed computing resources existing on the communication path. The mapping information generation unit 22 includes setting information in the mapping information. Here, for example, the Dijkstra method is known as a method for determining a communication path.

  The mapping information generation unit 22 outputs the mapping information generated in this way and the service definition to the setting instruction unit 24.

  Next, the setting instruction unit 24 generates setting information for the distributed computing resource and application arrangement information. The setting instruction unit 24 inputs mapping information and a service definition from the mapping information generation unit 22. The setting instruction unit 24 generates setting information and arrangement information based on the mapping information and the service definition. The setting instruction unit 24 transmits a setting request 41 including setting information and arrangement information, and maps the setting information and the arrangement information to the distributed computing resource. When completing the mapping to the distributed computing resource, the setting instruction unit 24 outputs a notification indicating the mapping result to the mapping information generation unit 22. When the mapping is normally completed, the setting instruction unit 24 outputs a completion notification indicating the normal completion of the mapping to the mapping information generation unit 22. On the other hand, if the mapping cannot be completed normally due to a failure of the distributed computing resource or the like, the setting instruction unit 24 outputs an incomplete notification indicating that the mapping has ended abnormally to the mapping information generation unit 22.

  The above is description of the structure of the distributed computing environment 1 provided with the service construction apparatus 2 and the service construction apparatus 2 in this embodiment.

[Description of operation]
Next, the operation of the service construction device 2 in the present embodiment having the above-described configuration will be described. FIG. 4 is a diagram illustrating an example of the service definition 42 of the service constructed by the service construction apparatus 2 in the present embodiment. The service definition in FIG. 4 shows the process flow of the service to be constructed.

  First, “Input” is an input to the service. “Output” is an output from the service. Processes A to F each indicate a processing unit having a certain function. In the process in the service shown in FIG. 4, the process A is executed for the input to the service. The process result of process A is output to process B, and process B is executed. The processing result of processing B is output to processing C and processing E, and processing C and processing E are executed. The process result of process C is output to process D and process D is executed. The execution result of process D and the execution result of process E are output to process F, and process F is executed. Then, the execution result of process F is output as an output from the service. In addition, the process result of the process B output to the process C and the process E is not restricted to the same content. Depending on the processing result of processing B, the output destination of the processing result may be selected. This depends on the processing contents in the service to be constructed.

  Next, FIG. 5 is a diagram illustrating an example of a distributed computing environment 1 in which a service is constructed by the service construction apparatus 2 in the present embodiment. The distributed computing environment 1 of FIG. 5 includes a firewall, a load balancer, a router, and servers A to G. The firewall, load balancer, and router are network resources 11. Servers A to G are IT resources 12. These distributed computing resources are connected to each other via a network, and can transmit and receive data.

  Next, FIG. 6 is a flowchart showing the operation of the service construction device 2 in the present embodiment. Hereinafter, an operation when the service construction apparatus 2 constructs the service shown in the service definition 42 of FIG. 4 in the distributed computing environment 1 of FIG. 5 as described above will be described.

  First, the application flow analysis unit 21 receives the service definition 42 as an input. The service definition 42 may be input to the service construction device 2 by the user from the input unit 140 or may be input via the network and the communication unit 130. The application flow analysis unit 21 analyzes the service definition 42 and generates an application flow analysis result (step S20). The application flow analysis unit 21 outputs the application flow analysis result together with the service definition 42 to the mapping information generation unit 22.

  The mapping information generation unit 22 inputs the application flow analysis result and the service definition 42 from the application flow analysis unit 21. Further, the mapping information generation unit 22 acquires application information from the application management unit 23 and resource information from the resource management unit 25. The mapping information generation unit 22 generates mapping information based on the application analysis result, application information, and resource information (step S22). The mapping information generation unit 22 outputs the mapping information together with the service definition 42 to the setting instruction unit 24.

  The setting instruction unit 24 receives the mapping information and the service definition 42 from the mapping information generation unit 22. The setting instruction unit 24 generates setting information and arrangement information based on the mapping information and the service definition 42. The setting instruction unit 24 transmits a setting request 41 including setting information and arrangement information, and performs service mapping to the distributed computing environment 1 (step S24). That is, the setting instruction unit 24 executes setting of distributed computing resources on the network resource 11 and the IT resource 12 and arrangement of applications based on the mapping information and the service definition 42.

  The setting instruction unit 24 outputs the mapping result to the mapping information generation unit 22. When the mapping is normally completed, the setting instruction unit 24 outputs a completion notification as a mapping result. On the other hand, when the mapping is not normally completed, the setting instruction unit 24 outputs an incomplete notification as a mapping result.

  The mapping information generation unit 22 inputs a completion notification or an incomplete notification from the setting instruction unit 24 as a mapping result. The mapping information generation unit 22 determines whether the mapping is successful (step S26). That is, the mapping information generation unit 22 determines whether the setting in the distributed computing environment and the application placement have been successful.

  If the mapping is successful (Yes in step S26), the mapping information generation unit 22 outputs a service construction completion notification 45 indicating that the service construction is completed (step S28). On the other hand, when the mapping is not successful (No in step S26), the process returns to step S22. In this case, the mapping information generation unit 22 generates mapping information again.

  The above is the description of the operation when the service construction device 2 constructs the service shown in the service definition 42 of FIG. 4 in the distributed computing environment 1 of FIG.

  Next, each step shown in the flowchart of FIG. 6 will be described in detail. First, the operation shown in step S20 in the flowchart of FIG. 6 will be described in detail. FIG. 7 is a flowchart showing in detail the operation in step S20 of the flowchart shown in FIG. 6 in the present embodiment.

  First, the application flow analysis unit 21 determines whether or not the service definition 42 has been input (step S100). As a confirmation method, the application flow analysis unit 21 generates and notifies an interrupt associated with the input of the service definition 42, or the application flow analysis unit 21 polls and inputs a specific storage area. A method for confirming the presence or absence of the above is conceivable. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120.

  When there is no input of the service definition 42 (No in step S100), the application flow analysis unit 21 repeats this step until the service definition 42 is input. On the other hand, when there is an input of the service definition 42 (Yes in Step S100), the application flow analysis unit 21 analyzes the service definition 42 (Step S110). In the analysis of the service definition 42, an application flow analysis result is generated based on the input / output relationship of processing included in the service definition 42. The input / output relationship of a process indicates a relationship between which process output is an input of which process or which process input is an output of which process.

  Here, FIG. 8 and FIG. 9 are diagrams illustrating examples of application flow analysis results in the present embodiment. The application flow analysis results shown in FIGS. 8 and 9 are generated based on the service shown in the service definition 42 of FIG. The application flow analysis result of FIG. 8 is a table in which a certain process is associated with a process to be executed next. For example, it is indicated that the next process of “Input” that is an input to the service is “Process A”. Further, it is indicated that the next process of “Process F” is “Output” which is an output from the service. Further, as shown in FIG. 9, the application flow analysis result may be generated as a table in which a certain process and a process immediately before the process are associated with each other. Note that the application flow analysis result is not limited to the table format as shown in FIGS.

  Next, returning to FIG. 7, the application flow analysis unit 21 transmits the application analysis result and the service definition 42 to the mapping information generation unit 22 (step S120). The above is the detailed description of the operation shown in step S20 of the flowchart of FIG. The application flow analysis unit 21 generates an application flow analysis result by the operation as described above.

  Subsequently, the operation shown in step S22 of the flowchart of FIG. 6 will be described in detail. FIG. 10 is a flowchart showing in detail the operation in step S20 of the flowchart of FIG. 6 in the present embodiment.

  First, the mapping information generation unit 22 determines whether or not the application flow analysis result and the service definition 42 are input (step S200). As a confirmation method, an interrupt associated with the input of the analysis result of the service definition 42 is generated and notified to the mapping information generation unit 22, or the mapping information generation unit 22 polls a specific storage area. A method for confirming the presence or absence of input can be considered. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120.

  If there is no input of the application flow analysis result and the service definition 42 (No in step S200), the mapping information generation unit 22 repeats this step until the application flow analysis result and the service definition 42 are input. On the other hand, when there is an input of the application flow analysis result and the service definition 42 (Yes in step S200), the mapping information generating unit 22 assigns the application 43 to each process constituting the service (step S210). The mapping information generation unit 22 refers to the application information of the application management unit 23 and assigns an application 43 that provides a function necessary for realizing each process constituting the service to each process.

  The result of allocating the application 43 to each process is stored as mapping information in the mapping information generating unit 22 or in an external storage area. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120. The mapping information at the time when step S210 is completed is information that associates a certain application with an application to be executed next.

  Here, FIG. 11 is a diagram illustrating an example of mapping information at the time when step S210 in the present embodiment is completed. The mapping information shown in FIG. 11 is generated based on the application flow analysis result shown in FIG. For example, an application 43 (hereinafter sometimes referred to as “App”) that performs processing after “Input” that is an input to the service is indicated as “AppA”. Further, it is indicated that the processing result by “AppF” is “Output” which is an output from the service. Note that the mapping information is not limited to the table format as shown in FIG.

  Next, returning to FIG. 10, the mapping information generating unit 22 allocates the application allocated to each process to the distributed computing resource (step S220). The mapping information generation unit 22 refers to the resource information of the resource management unit 25 and assigns the mapping information to the distributed computing resources. The result of assigning the mapping information to the distributed computing resource is stored in the mapping information generating unit 22 or in an external storage area. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120. The mapping information at the time when step S220 is completed is information that associates a certain application, a distributed computing resource that executes the application, and an application to be executed next to the application.

  Here, FIG. 12 is a diagram illustrating an example of mapping information at the time when step S220 in the present embodiment is completed. The mapping information shown in FIG. 12 is obtained by associating distributed computing resources with the mapping information shown in FIG. For example, “Input”, which is an input for a service, is input to “Input Device”. “AppA” is executed by the “firewall”. Further, “AppF” is executed by “Server F”, and the execution result of “Server F” is output as “Output” from the service. Note that the mapping information is not limited to the table format as shown in FIG.

  In addition, when the application 43 is allocated to each process in step S210, the mapping information generation unit 22 generates a candidate as an allocation candidate in a case where a certain process is a process capable of realizing the function with either the IT resource 12 or the network resource 11. Keep it. The mapping information generation unit 22 can also perform an operation of determining which candidate is used based on the evaluation function when allocating distributed computing resources to the application 43 in step S220. Here, the evaluation function is a function using indexes such as power consumption, cost, and performance of the distributed computing resource.

  Next, returning to FIG. 10, the mapping information generation unit 22 determines whether resources on the path exist between the selected distributed computing resources (step S230). Here, the resource on the path is a distributed computing resource that exists on a path for performing communication between selected distributed computing resources as a result of assigning the application 43 to the distributed computing resource. It is necessary to make appropriate settings for such resources on the route.

  As a determination method for determining whether or not a resource on a path exists, for example, an inquiry is made to a management system that manages all distributed computing resources existing in the distributed computing environment 1 that is not illustrated in FIG. A method is conceivable. Alternatively, a tool for searching for a route from a certain server to the server may be used. Such a tool is exemplified in “Tracroute”.

  Here, FIG. 13 is a diagram showing resources on the path existing between distributed computing resources to which applications are assigned in the present embodiment. Referring to FIG. 13, for example, “Input” that is an input to a service is processed by “AppA”. “AppA” is assigned to the firewall. In order for “Input” to reach the firewall, it is necessary to go through a router which is a resource on the route. Further, a server C that is a resource on the path exists between the load balancer assigned with the process “AppB” and the server F assigned with “AppC” that performs the next process of “AppB”. In such a case, it is necessary to make settings for the router and the server C in order to enable appropriate communication between the applications 43.

  Next, returning to FIG. 10, when there is a resource on the path between the selected distributed computing resources (Yes in step S230), the mapping information generating unit 22 adds the information on the resource on the path to the mapping information ( Step S240). On the other hand, when there is no resource on the path between the selected distributed computing resources (No in step S230), the mapping information generation unit 22 does not add the information on the resource on the path to the mapping information. In either case, the process proceeds to step S250.

  Here, FIG. 14 is a diagram illustrating an example of mapping information at the time when step S240 in the present embodiment is completed. The mapping information in FIG. 14 is obtained by adding information on a route resource to the mapping information in FIG. For example, a router which is a resource on the path is associated between “Input” which is an input to a service and a firewall to which “AppA” which should process “Input” is assigned. Further, a server C, which is a resource on the path, is associated between the load balancer assigned with the process “AppB” and the server F assigned with “AppC” that performs the next process of “AppB”. . Note that the mapping information is not limited to the table format as shown in FIG.

  Next, returning to FIG. 10, the mapping information generation unit 22 outputs the generated mapping information together with the service definition 42 to the setting instruction unit 24 (step S250). The above is the detailed description of the operation shown in step S22 of the flowchart of FIG. The mapping information generation unit 22 generates mapping information by the operation as described above.

  Next, the operation shown in step S24 of the flowchart of FIG. 6 will be described in detail. FIG. 15 is a flowchart showing in detail the operation in step S24 of the flowchart of FIG. 6 in the present embodiment.

  First, the setting instruction unit 24 checks whether or not the mapping information and the service definition 42 are input (step S400). As a confirmation method, the setting instruction unit 24 generates an interrupt associated with the input of mapping information and notifies the setting instruction unit 24, or the setting instruction unit 24 polls a specific storage area to check whether there is an input. The method of doing etc. can be considered. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120.

  If there is no input of the mapping information and the service definition 42 (No in step S400), the setting instruction unit 24 repeats this step until the mapping information and the service definition 42 are input. On the other hand, when the mapping information and the service definition 42 are input (Yes in step S400), the setting instruction unit 24 determines whether the application 43 is placed on the distributed computing resource based on the mapping information and the service definition 42. Setting information is generated (step S410).

  Here, the arrangement information of the application 43 includes information necessary for the application 43 to operate normally. For example, information such as the program code of the application 43, the argument of the application, the IP address and application port number of the opposite destination of data transmission / reception are exemplified. The setting information is exemplified by information such as routing information to the router and filtering information to the firewall.

  The setting instruction unit 24 transmits a setting request 41 including the generated arrangement information and setting information in order to reflect the distributed computing resource (step S420). The setting instruction unit 24 waits for responses (ACK: Acknowledge) from all the distributed computing resources that have transmitted the setting request 41 (step S430). As a processing example when waiting for a response, for a method of waiting until a response is received from all the distributed computing resources that transmitted the setting request 41, or for a distributed computing resource that has not received a response after waiting for a certain time Another possible method is to repeat the process of transmitting the setting request 41 a predetermined number of times. In addition, there may be a case where the setting fails due to a network trouble or a failure of the distributed computing resource. Therefore, a method of determining that service mapping has failed for a distributed computing resource that cannot receive a response after a certain time has elapsed or after a certain number of request reissues has been considered.

  The setting instruction unit 24 notifies the mapping information generation unit 22 of the mapping result (step S440). When the mapping is normally completed, the setting instruction unit 24 outputs a completion notification as a mapping result. On the other hand, when the mapping is not normally completed, the setting instruction unit 24 outputs an incomplete notification as a mapping result. The above is the detailed description of the operation shown in step S24 of the flowchart of FIG. The setting instruction unit 24 performs setting to the distributed computing resource and arrangement of the application by the operation as described above.

  Next, the operation shown in step S430 in the flowchart of FIG. 15 will be described in detail. FIG. 16 is a flowchart showing in detail the operation in step S430 of the flowchart of FIG. 15 in the present embodiment.

  First, the setting instruction unit 24 determines whether responses have been returned from all the distributed computing resources that have transmitted the setting request 41 for reflecting the arrangement information and setting information of the application 43 (step S432). If the response is returned from all the distributed computing resources (Yes in step S432), the setting instruction unit 24 determines that the service mapping is successful (step S433). On the other hand, if the responses are not returned from all the distributed computing resources (No in step S432), the setting instruction unit 24 determines whether the setting request 41 has been reissued a specific number of times for the corresponding distributed computing resources. (Step S434). Here, the specific number of times is a predetermined number of times serving as a threshold for determining that service mapping has failed.

  If the number of reissues of the setting request 41 has reached a specific number (Yes in step S434), the setting instruction unit 24 determines that the service mapping has failed (step S435). On the other hand, when the number of reissues of the setting request 41 has not reached a specific number (No in step S434), the setting instructing unit 24 reissues the setting request 41 for the corresponding distributed computing resource (step S434). S436). The above is the detailed description of the operation shown in step S430 of the flowchart of FIG. The setting instruction unit 24 determines the success or failure of the mapping to the distributed computing resource by the operation as described above.

  Next, the operation shown in step S26 of the flowchart of FIG. 6 will be described in detail. FIG. 17 is a flowchart showing in detail the operation in step S26 of the flowchart of FIG. 6 in the present embodiment.

  First, the mapping information generation unit 22 determines the presence / absence of a service mapping result notification from the setting instruction unit 24 (step S260). As a confirmation method, an interrupt associated with the input of the analysis result of the service definition 42 is generated and notified to the mapping information generation unit 22, or the mapping information generation unit 22 polls a specific storage area. A method for confirming the presence or absence of input can be considered. The storage area in this case corresponds to the memory of the storage unit 100, the hard disk, or the register of the control unit 120.

  If there is no notification of the mapping result (No in step S260), the mapping information generation unit 22 repeats this step until there is a notification of the mapping result. On the other hand, when there is a notification of the mapping result (Yes in step S260), the mapping information generation unit 22 checks the content of the notification (step S270). The mapping information generation unit 22 determines whether the service mapping is successful based on the content of the notification (step S280).

  If the mapping is successful (Yes in step S280), that is, if the mapping result is a completion notification, the process proceeds to step S28 shown in FIG. In this case, as shown in step S28 of FIG. 6, the service construction completion notification 45 is output. On the other hand, if the mapping has failed (No in step S280), that is, if the mapping result is an incomplete notification, the process proceeds to step S22 shown in FIG. In this case, the mapping information generation unit 22 generates mapping information again. The above is the detailed description of the operation shown in step S26 of the flowchart of FIG. The mapping information generation unit 22 determines the completion of the service construction for the distributed computing resource by the operation as described above.

  The above is the description of the operation method of the service construction device 2 in the present embodiment.

  As described above, in the present embodiment, the mapping information generation unit 22 of the service construction device 2 does not distinguish between the processing executed so far on the IT resource 12 and the processing executed so far on the network resource 11. Mapping information is generated by handling uniformly. That is, the mapping information generation unit 22 generates mapping information by assigning each process on the resource selected without discrimination between the IT resource 12 and the network resource 11. In addition, the mapping information generation unit 22 extracts resources on the route to enable appropriate communication between the processes performed on the selected IT resource 12 and the network resource 11, and also applies to these resources on the route. Generate mapping information. In this way, mapping can be performed in a single process for both the IT resource 12 and the network resource 11. Therefore, the time required for service construction can be shortened.

  The above is the description of the service construction device in the present embodiment.

(Second Embodiment)
Next, a service construction system according to the second embodiment of the present invention will be described.

[Overview]
The service construction system in this embodiment includes a visualization device 3 that visualizes a service constructed in the distributed computing environment 1 based on mapping information and a service definition 42. The user can check the constructed service with the visualization device 3.

[Description of configuration]
First, the configuration of the service construction system in this embodiment will be described. As in the first embodiment, the service construction system of the present embodiment includes a distributed computing environment 1 and a service construction device 2, and further includes a visualization device 3. The service construction system in the present embodiment is different from the first embodiment in that the visualization apparatus 3 is further provided. Therefore, the description of the same parts as in the first embodiment will be omitted, and the description will focus on parts different from the first embodiment.

  FIG. 18 is a functional block diagram showing functions of the service construction device 2 and the visualization device 3 in the present embodiment. Note that the service construction device 2 of this embodiment has a hardware configuration as shown in FIG. 2 as in the first embodiment.

  The visualization device 3 visualizes a service constructed in the distributed computing environment 1. The visualization device 3 is connected to the mapping information generation unit 22 of the service construction device 2. When the mapping of the service is completed successfully and the service construction completion notification 45 is output, the mapping information generation unit 22 of the present embodiment outputs the service construction completion notification 45 including the mapping information and the service definition 42. The visualization device 3 visualizes the service constructed in the distributed computing environment 1 based on the mapping information and the service definition 42. The visualization device 3 may be constructed outside the service construction device 2 as shown in FIG. 18 or may be constructed inside the service construction device. The service construction device 2 is the same as that of the first embodiment except for the above.

  The above is description of the structure of the service construction apparatus 2 in this embodiment.

[Description of operation]
Next, the operation of the service construction device 2 in this embodiment will be described. FIG. 19 is a flowchart showing the operation of the service construction system in this embodiment. Note that the flowchart shown in FIG. 19 shows the processing executed in step S28 of the flowchart shown in FIG. Further, it is assumed that the mapping information at this time is in the state shown in FIG.

  First, the mapping information generation unit 22 determines whether there is a process associated with a plurality of resources on the route in the mapping information (step S282). When there is a process associated with a plurality of resources on the path (Yes in step S282), the mapping information generation unit 22 adds the corresponding process to the mapping information as a new process (step S284). Specifically, the mapping information generation unit 22 displays information related to the “next process” of the process associated with a plurality of resources on the path “next” The processing to be performed with the resources on the route is added to the mapping information as the information of “Processing”. In the process to be performed on the newly added resource on the route, the “next process” information is the “next process” information of the corresponding process before the change. The “route resource” information is obtained by removing the information of the route resource through which the corresponding process first passes from the “route resource” information of the corresponding process before the change. Thereafter, the process returns to step S282, and it is determined whether there are other processes associated with a plurality of resources on the path.

  Here, FIG. 20 is a diagram illustrating an example of mapping information at the time when step S284 in the present embodiment is completed. The mapping information in FIG. 20 is obtained by adding processing associated with a plurality of resources on the route as new processing to the mapping information in FIG. Note that the mapping information is not limited to the table format as shown in FIG.

  For example, in FIG. 14, “AppD” is a process associated with a plurality of resources on the path. There are two resources on the path between the “AppD” process and the “AppF” process, “ServerC” and “Router”. In the mapping information after executing the process of step S284 shown in FIG. 20, the information related to “next process” of “AppD” is replaced with the process of “Forwarding 1” executed by “ServerC”. That is, the transfer process executed by “ServerC” is added as a process “Forwarding 1”. Here, “ServerC” is selected from “ServerC” and “Router” because it first passes through “ServerC” on the communication path from “AppD” to “AppF”.

  Note that the “next process” of the process “Forwarding 1” is “AppF” associated with “AppD” in FIG. Furthermore, the “route resource” of the process “Forwarding 1” is “Router” obtained by removing “ServerC” from “ServerC” and “Router” associated with “AppD” in FIG. Further, the “next processing” of “AppD” is the added “Forwarding 1”.

  Next, returning to FIG. 19, the mapping information generation unit 22 determines whether there is a process associated with the route resource when there is no process associated with the plurality of route resources (No in step S <b> 282). (Step S286). Note that at the stage of step S286, there is no processing associated with a plurality of resources on the path. If there is no process associated with the resource on the route (No in step S286), the process proceeds to step S290.

  If there is a process associated with the resource on the path (Yes in step S286), the mapping information generation unit 22 adds the corresponding process to the mapping information as a new process (step S288). Specifically, the mapping information generation unit 22 uses the information related to the “next process” of the corresponding process as information on the process executed on the path resource, and adds the process to be performed on the path resource to the mapping information. . The information of “next process” of the process to be performed on the resource on the route becomes “next process” of the corresponding process before the change.

  Here, FIG. 21 is a diagram illustrating an example of mapping information at the time when step S288 in the present embodiment is completed. The mapping information in FIG. 21 is added to the mapping information in FIG. 20 as a process by a resource on the route and a new process. Note that the mapping information is not limited to the table format as shown in FIG.

  For example, in FIG. 20, “AppB” is a process associated with a resource on the path. “AppB” includes a process using “ServerC” as a resource on a route and a process using “Router” as a resource on a route. In the mapping information after executing the process of step S288 shown in FIG. 21, the information related to the “next process” of one “AppB” is replaced with the process “Forwarding 3” executed by “ServerC”. That is, the transfer process executed by “ServerC” is added as a process “Forwarding 3”. At this time, the “next process” of the process “Forwarding 3” is “AppC” associated with “AppB” in FIG. The “next process” of “AppB” is the added “Forwarding 3”.

  In the mapping information shown in FIG. 21, the information related to “next processing” of the other “AppB” is replaced with the processing “Forwarding 4” executed by “Router”. That is, the transfer process executed by “Router” is added as a process called “Forwarding 4”. At this time, the “next process” of the process “Forwarding 4” is “AppE” associated with the other “AppB” in FIG. The “next process” of the other “AppB” is the added “Forwarding 4”.

  Similarly, processes such as “Input”, “Forwarding 1”, and “AppF” in the mapping information in FIG. 20 are performed to add the associated resources on the route as new processes. By performing such processing, there is no processing associated with the resource on the path in the mapping information after executing step S288 shown in FIG. The processing of the IT resource 12 and the processing of the network resource 11 can be expressed in a unified format.

  Next, returning to FIG. 19, the mapping information generation unit 22 outputs the mapping information and the service definition 42 together with the service construction completion notification 45 (step S290). The visualization device 3 receives the mapping information and the service definition 42 as inputs. The visualization device 3 visualizes the service constructed in the distributed computing environment 1 based on the mapping information and the service definition 42 (Step S292). The above is description of operation | movement of the service construction apparatus 2 in this embodiment.

  Here, FIG. 22 is a diagram illustrating an example of a service visualized by the visualization device 3 in the present embodiment. The visualization device 3 displays windows W41 to W44 as shown in FIG. Such a display may be displayed on a display device that the visualization device 3 has independently, or may be displayed on the LCD or the like of the output unit 150 of the service construction device 2. Each window will be described below.

  First, the window W41 is a window for selecting a service. The window W41 displays a list of services currently built in the distributed computing environment. The user can select a service to be visualized in the window W41.

  Next, the window W42 is a window for displaying the distributed computing environment 1. The window W42 displays the distributed computing resources of the distributed computing environment 1 together with the network connection status. In the window W42, the distributed computing environment 1 corresponding to the mapping status of the service selected in the window W41 is displayed.

  Next, the window W43 is a window for displaying the service definition. The window W43 displays information related to connections between processes constituting the service based on the service definition of the service selected in the window W41.

  Next, the window W44 is a window for displaying mapping information. The window W44 displays mapping information of the service selected in the window W41.

  Next, FIG. 23 is a diagram illustrating an example in which the service of the service definition illustrated in FIG. 4 in the present embodiment is visualized by the visualization device 3.

  The window W41 displays services established in the distributed computing environment 1. When the user selects a service in the window W41, the service definition 42 is displayed in the window W43. This service definition 42 is the service definition 42 shown in FIG. Also, the mapping information is displayed in the window W44. This mapping information is the mapping information shown in FIG. Further, the contents of the mapping information are visualized and displayed on the window W42.

  Next, FIG. 24 is a diagram illustrating a case where specific information is selected in the visualization display of FIG. 23 in the present embodiment.

  For example, it is assumed that the user has selected specific data of the mapping information displayed in the window W44. Referring to FIG. 24, the process “AppA” is selected. Accordingly, the process A corresponding to the process “AppA” is highlighted in the window W43. In the window W42, “Firewall” for executing the process “AppA” and the process “AppA” is highlighted. Similarly, when a specific process is selected in the window W43, the corresponding mapping information in the window W44, the corresponding distributed computing resource in the window W42, and the application 43 are highlighted. When a specific distributed computing resource or application 43 is selected in the window W42, mapping information corresponding to the window W44 and processing corresponding to the window W43 are highlighted.

  Thus, the user can confirm information corresponding to the processing by selecting a specific display. As a result, mapping information including information on resources on the route that is not included in the original service definition is visualized, and the processes constituting the service can be confirmed in detail. Therefore, it is possible to confirm in detail how the distributed computing resources of the distributed computing environment 1 are used in a certain service.

  The above is description of operation | movement of the service construction apparatus 2 in this embodiment.
