Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a computer resource providing system 1 according to the present embodiment. The computer resource providing system 1 includes a user terminal 10 and a plurality of physical machines 20 (physical machine 20-1, physical machine 20-2, physical machine 20-3, physical machine 20-4, physical machine 20-5,... ), A computer resource providing device 30, a storage management device 40, a plurality of storage devices 42 (storage device 42-1, storage device 42-2,...) Connected to the storage management device 40, and a machine The computer apparatus includes an image management apparatus 50 and a virtual network management apparatus 60, and these computer apparatuses are connected via a network. The plurality of physical machines 20 have the same configuration, and unless otherwise distinguished, “−1”, “−2”, etc. are omitted and described as physical machines 20. The plurality of storage apparatuses 42 have the same configuration, and unless otherwise distinguished, “−1”, “−2”, etc. are omitted and described as the storage apparatus 42.

  The user terminal 10 is a computer terminal connected to the computer resource providing apparatus 30, the physical machine 20, and the storage management apparatus 40 via a network, and uses the computer resources provided by the computer resource providing system 1. The user terminal 10 includes an input unit such as a keyboard and a mouse, a display unit that is a display, an output unit, a control unit, a storage unit, and the like. The user terminal 10 transmits a computer resource provision request to the computer resource provision apparatus 30 in response to an operation input from the user. The user terminal 10 is a computer resource provided to itself based on computer resource identification information (for example, an IP (Internet Protocol) address) transmitted from the computer resource providing device 30 in response to the transmitted provision request. It can be used by connecting to the machine 20 via a network. Here, one user terminal 10 is shown and described, but a plurality of user terminals 10 of a plurality of users may be connected to the computer resource providing system 1.

  The physical machine 20 is a computer device that is connected to the user terminal 10 and the computer resource providing device 30 via a network and includes computer resources such as a CPU (Central Processing Unit), a memory, and a disk. The computer resources of the physical machine 20 are used by the user terminal 10. Here, of the plurality of physical machines 20, a virtual machine is activated in the determined physical machine 20, and the activated virtual machine is used by the user terminal 10. The other physical machines 20 are used for the user terminal 10 without being activated. In the present embodiment, a virtual machine is activated on the physical machine 20-1, the physical machine 20-2, and the physical machine 20-3 and used for the user terminal 10, and the physical machine 20-4 and the physical machine 20 are used. The virtual machine is used for the user terminal 10 without being activated.

  The computer resource providing apparatus 30 is a computer apparatus that causes the user terminal 10 to use computer resources of a plurality of physical machines 20 connected via a network. The computer resource providing apparatus 30 includes a provision request receiving unit 31, a physical machine information storage unit 32, a physical machine management unit 33, a virtual machine information storage unit 34, and a virtual machine management unit 35.

  The provision request receiving unit 31 receives a provision request for either a physical machine or a virtual machine from the user terminal 10. Specifically, for example, the provision request accepting unit 31 has a function of a web server, and transmits an input screen, which is a web page for accepting a computer resource provision request, to the user terminal 10 in response to a connection from the user terminal 10. To do. FIG. 2 is a diagram illustrating an example of a provision request input screen that the provision request receiving unit 31 transmits to the user terminal 10. On the input screen, selection items such as OS (symbol a), software (symbol b), computer resource size (symbol c), and machine type (symbol d) are displayed.

  The OS indicates an OS to be operated on the provided computer resource, and can be selected from a plurality of OSs. The software indicates software such as application software or server software that runs on the OS. Here, depending on the software to be operated on the computer resource, there are cases where the license contract prohibits the operation on the virtual machine or the operation on the virtual machine is not guaranteed. When such software is selected, control is performed so that a virtual machine cannot be selected in the machine type and only a physical machine can be selected. As a result, even software that is prohibited from being operated in a virtual machine can be operated on a computer resource provided via a network without any licensing problems.

  The size of the computer resource indicates the type of size determined according to the CPU performance (operating frequency, the number of cores, etc.), the memory capacity, and the disk capacity as the provided computer resources. The machine type indicates which computer resource is requested to be provided: a virtual machine or a physical machine. For example, when the user wants to operate and use a web server or an AP server in the provided computer resource, the user can select a virtual machine. On the other hand, for example, on the provided computer resource, if you want to use software that is prohibited from operating in a virtual machine due to a license or whose operation is not guaranteed, or the same as the physical machine that you use When it is desired to avoid that a virtual machine used by another user is operating on the physical machine, the physical machine can be selected. In the user terminal 10, after these selection items are input, when a provision request transmission button indicated by a symbol e is pressed, a provision request including the input information is transmitted to the provision request receiving unit 31.

  The physical machine information storage unit 32 stores physical machine information in which information indicating whether or not the physical machine 20 is used for the user terminal 10 is associated with each piece of identification information of the plurality of physical machines 20. Yes. FIG. 3 is a diagram illustrating a data example of physical machine information stored in the physical machine information storage unit 32. The physical machine information includes information in which a provision destination, a CPU (operation frequency and the number of cores), a memory capacity, and a disk capacity are associated with each physical machine ID for identifying the physical machine 20. The providing destination is information indicating whether or not the corresponding physical machine 20 is used by the user terminal 10. When the virtual machine is activated by the virtual machine management unit 35 and used by the user terminal 10, “ If the virtual machine management unit is associated with the user terminal 10 as a physical machine, the user ID is associated with the virtual machine management unit. It is done.

  When the provision request receiving unit 31 receives the physical machine provision request, the physical machine management unit 33 causes the user terminal 10 to use the physical machine 20. Here, “use” refers to transmitting identification information (for example, IP address) of the physical machine 20 to the user terminal 10 that is the transmission source of the provision request, and the connection from the user terminal 10 in the physical machine 20 Is set to allow operations with administrator rights. For example, when the provision request receiving unit 31 receives a physical machine provision request, the physical machine management unit 33 selects among the plurality of physical machines 20 based on the physical machine information stored in the physical machine information storage unit 32. It is determined whether there is a physical machine 20 that is not used by the user terminal 10. If it is determined that there is a physical machine that is not used by the user terminal 10, the physical machine 20 is used by the user terminal 10. Here, whether or not there is a physical machine 20 that is not used in the user terminal 10 can be determined by whether or not there is physical machine information associated with “free” in the provision destination.

  When the physical machine management unit 33 determines that there is no physical machine 20 that is not used by the user terminal 10, the physical machine management unit 33 transmits a physical machine return request to the virtual machine management unit 35. That is, even if there is no free space in the physical machine 20 managed by the physical machine management unit 33, there may be a free space in the physical machine 20 that has been paid out to the virtual machine management unit 35. In this case, the returned physical machine 20 can be provided to the user terminal 10 by returning the physical machine 20 paid out to the virtual machine management unit 35 to the physical machine management unit 33.

  Further, when the physical machine management unit 33 receives a physical machine provision request from the virtual machine management unit 35, the physical machine management unit 33 is not used by the user terminal 10 based on the physical machine information stored in the physical machine information storage unit 32. It is determined whether there is a physical machine. If it is determined that there is a physical machine 20 that is not used by the user terminal 10, the physical machine 20 is paid out to the virtual machine management unit 35. Here, paying out the physical machine 20 means that the virtual machine management unit 35 is associated with the provision destination of the physical machine 20 and stored in the physical machine information storage unit 32, and the management of the physical machine 20 is managed by the virtual machine management unit. This is what 35 does. The physical machine 20 paid out by the physical machine management unit 33 cannot be used as a physical machine by the user terminal 10 until it is returned from the virtual machine management unit 35.

  The virtual machine information storage unit 34 is activated for each physical machine ID for identifying a physical machine that is determined to activate the virtual machine among the plurality of physical machines 20 connected via the network. Virtual machine information indicating whether or not the used virtual machine is used in the user terminal 10 is stored. Further, the virtual machine information storage unit 34 stores payout physical machine information indicating the physical machine that has been paid out from the physical machine management unit 33 to the virtual machine management unit 35. FIG. 4 is a diagram illustrating a data example of payout physical machine information. The payout physical machine information includes, for each physical machine ID for identifying the physical machine 20 assigned to the virtual machine management unit 35, a CPU (operation frequency and the number of cores) indicating the performance of the physical machine, a memory capacity, Information with disk capacity is associated.

  FIG. 5 is a diagram illustrating a data example of virtual machine information stored in the virtual machine information storage unit 34. In the virtual machine information, a physical machine ID for identifying the physical machine 20 issued from the physical machine management unit 33, a virtual machine ID for identifying a virtual machine activated on the physical machine, and the virtual machine are assigned. Information on the CPU (operating frequency and number of cores), memory capacity, and disk capacity is associated.

  When the provision request receiving unit 31 receives the provision request for the virtual machine, the virtual machine management unit 35 activates the virtual machine to the physical machine 20 that has been issued from the physical machine management unit 33, and uses the virtual machine that has been activated by the user. The terminal 10 is used. Here, “use” means that the virtual machine identification information (eg, IP address) is transmitted to the user terminal 10 that is the source of the provision request, and the connection from the user terminal 10 is permitted in the virtual machine. It means that it is set to allow operations with administrator rights. Here, when the physical machine 20 is issued from the physical machine management unit 33, the virtual machine management unit 35 installs virtualization software on the physical machine 20, and on the computer resource virtualized by the virtualization software, Start the virtual machine.

  For example, when the provision request receiving unit 31 receives a provision request for a virtual machine, the virtual machine management unit 35 performs a virtual process started by the physical machine 20 based on the virtual machine information stored in the virtual machine information storage unit 34. It is determined whether there is a virtual machine that is not used for the user terminal 10 among the machines. If it is determined that there is a virtual machine that is not used for the user terminal 10, the virtual machine is used by the user terminal 10. . Here, whether or not there is a virtual machine that is not used in the user terminal 10 can be determined by whether or not there is virtual machine information associated with “free” in the provision of the virtual machine. Further, when the size is included in the provision request, the virtual machine management unit 35 determines whether or not there is a free computer resource corresponding to the size.

  When the virtual machine management unit 35 determines that there is no virtual machine that is not used by the user terminal 10, the virtual machine management unit 35 transmits a physical machine payout request to the physical machine management unit 33. That is, even if there is no free space in the physical machine 20 managed by the virtual machine management unit 35, there may be a free space in the physical machine 20 managed by the physical machine management unit 33. In this case, when a new physical machine 20 is received from the physical machine management unit 33, the virtual machine can be activated on the physical machine 20 and provided to the user terminal 10.

  When the virtual machine management unit 35 receives a physical machine return request from the physical machine management unit 33, the virtual machine is used by the user terminal 10 based on the virtual machine information stored in the virtual machine information storage unit 34. It is determined whether there is a physical machine that is not used, and if it is determined that there is a physical machine that is not used by the user terminal 10, the physical machine 20 is returned to the physical machine management unit 33. Here, whether there is a physical machine whose virtual machine is not used in the user terminal 10 can be determined by whether all of the virtual machines on the same physical machine are “free”. At this time, if the physical machine can be made free by moving (migrating) the virtual machines activated on the plurality of physical machines 20, the virtual machine management unit 35 moves the virtual machine and enters a free state. The physical machine can be returned to the physical machine management unit 33. Here, returning the physical machine 20 to the physical machine management unit 33 means that the physical machine 20 is deleted from the paid-out virtual machine information stored in the virtual machine information storage unit 34 and the management of the physical machine 20 is managed by the physical machine. This means that the management unit 33 performs the operation. The physical machine 20 returned by the virtual machine management unit 35 cannot be used by the user terminal 10 as a virtual machine until it is paid out from the physical machine management unit 33.

  The storage management device 40 is a computer device connected to a plurality of storage devices 42 and includes a storage management unit 41. When the provision request received from the user terminal 10 by the computer resource providing device 30 is included in the provision request, the storage management unit 41 causes the user to use the storage device 42 having a capacity corresponding to the provision request.

  The machine image management device 50 is a computer device connected to the computer resource providing device 30 and includes a machine image management unit 51. The storage area of the machine image management unit 51 stores a predetermined OS and machine image for each software. In response to a request from the computer resource providing apparatus 30, the machine image management apparatus 50 reads out and transmits a machine image stored in the virtual network management unit 61.

  The virtual network management device 60 is a computer device connected to the computer resource providing device 30 and the physical machine 20 and includes a virtual network management unit 61. The virtual network management unit 61 constitutes a virtual network of a group of machines provided to the user terminal 10. That is, the virtual network management device 60 sets a closed virtual network (VLAN (Virtual Local Area Network)) for the user by setting a switch or the like.

Next, an operation example of the computer resource providing system 1 according to the present embodiment will be described. FIG. 6 is a flowchart illustrating an operation example of the computer resource providing apparatus 30.
When connected from the user terminal 10, the provision request accepting unit 31 of the computer resource providing apparatus 30 transmits a provision request input screen to the user terminal 10. The user terminal 10 displays the input screen transmitted from the computer resource providing device 30. When a selection item is input from the user and the provision request transmission button is pressed, the provision request including the input information is displayed as the computer resource. To the providing device 30.

  The provision request reception part 31 of the computer resource provision apparatus 30 receives the provision request transmitted from the user terminal 10 (step S1). The provision request receiving unit 31 of the computer resource providing apparatus 30 determines whether or not the machine type included in the received provision request is “physical machine” (step S2). When the provision request receiving unit 31 determines that the machine type included in the provision request is “physical machine” (step S2: YES), the physical machine management unit 33 determines the physical machine corresponding to the size included in the provision request. It is determined whether there is a vacancy (step S3). If the physical machine management unit 33 determines that there is a free space in the physical machine 20 corresponding to the size included in the provision request (step S3: YES), the machine image management is performed on the machine image corresponding to the OS and software included in the provision request. The machine image read from the device 50 is installed in the physical machine 20 determined to be empty, and the physical machine 20 is activated. Then, the computer resource is provided by transmitting the IP address of the physical machine 20 to the user terminal 10 (step S6).

  In step S3, if the physical machine management unit 33 determines that there is no free space in the physical machine 20 according to the size included in the provision request (step S3: NO), the virtual machine management unit 35 includes the virtual machine management unit 35. An inquiry is made as to whether or not the physical machine to be managed is free (step S4). If the virtual machine management unit 35 determines that there is no available physical machine (step S4: NO), there is no computer resource that can be provided, and the process ends as an error (step S11). If the virtual machine management unit 35 determines that there is a free physical machine (step S4: YES), the physical machine management unit 33 transmits a physical machine return request to the virtual machine management unit 35 (step S5). When the physical machine is returned from the virtual machine management unit 35 to the physical machine management unit 33 in response to the return request of the physical machine, the physical machine management unit 33 sets “free” to the provision destination of the returned physical machine 20. The physical machine information storage unit 32 stores the information in association with each other, and the process proceeds to step S6.

  When the provision request receiving unit 31 determines that the machine type included in the provision request is not “physical machine” (“virtual machine”) (step S2: NO), the virtual machine management unit 35 is included in the provision request. It is determined whether there is a free virtual machine according to the size (step S7). If the virtual machine management unit 35 determines that there is a free virtual machine corresponding to the size included in the provision request (step S7: YES), the machine image management apparatus displays a machine image corresponding to the OS and software included in the provision request. The machine image read from 50 is installed in the virtual machine determined to be free, and the virtual machine is activated. Then, the computer resource is provided by transmitting the IP address of the virtual machine to the user terminal 10 (step S10).

  In step S7, if the virtual machine management unit 35 determines that there is no free virtual machine according to the size included in the provision request (step S7: NO), the physical machine management unit 33 manages the physical machine management unit 33. An inquiry is made as to whether or not there is a free physical machine (step S8). If the physical machine management unit 33 determines that there is no available physical machine (step S8: NO), the process proceeds to step S11, and the process ends as an error. When the physical machine management unit 33 determines that there is a free physical machine (step S8: YES), the virtual machine management unit 35 transmits a physical machine payout request to the physical machine management unit 33 (step S9). When a physical machine is paid out from the physical machine management unit 33 to the virtual machine management unit 35 in response to a physical machine payout request, the virtual machine management unit 35 installs virtualization software on the paid out physical machine 20. The process proceeds to step S10.

  As described above, according to the present embodiment, the computer resource providing apparatus 30 manages the virtual machine and the physical machine at the same time, and selects either the virtual machine or the physical machine according to the provision request from the user terminal 10. It can be provided to the user terminal 10. In other words, a virtual machine can be activated and provided in response to a provision request from the user terminal 10, and in some cases, not a virtual machine but a physical machine can be provided as it is. For example, if a user wants to use software that is prohibited from operating on a virtual machine or whose operation is not guaranteed on the virtual machine due to a license contract, provide the physical machine and the physical machine Software can be run on the above. Alternatively, for example, when a plurality of virtual machines are operating in one physical machine, the clock managed by the OS of the virtual machine may not be accurate. In such a case, when performing a benchmark test on the virtual machine, the accuracy of performance measurement deteriorates. For this reason, when it is desired to perform strict performance measurement, the result is more accurate on the physical machine than on the virtual machine. In such a case, performance measurement can be performed using a physical machine.

  In addition, according to the present embodiment, for example, compared to a hosting service that provides a user with all of a plurality of physical machines as physical machines, a virtual machine is provided when the physical machine is free, The utilization efficiency of computer resources can be improved by combining the virtual machine and the physical machine, such as providing a physical machine when the virtual machine is free. In addition, if a physical machine is used, virtual machines of different users do not operate on the same physical machine, so that the possibility of being attacked by the virtual machine can be eliminated. In addition, the virtual machines of different users operating on the same physical machine are not affected by the large amount of resources consumed.

  It is to be noted that a computer resource is provided by recording a program for realizing the function of the processing unit in the present invention on a computer-readable recording medium, causing the computer system to read and execute the program recorded on the recording medium. May be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
