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, a computer resource providing device 20, a machine management support device 30, and a plurality of physical machines 40 (physical machine 40-1, physical machine 40-2, physical machine 40-3, ..)). Here, since the plurality of physical machines 40 have the same configuration, unless otherwise distinguished, “−1”, “−2”, and the like are omitted and described as the physical machine 40. Here, three physical machines 40 are shown and described, but any number of physical machines 40 may be connected to the computer resource providing apparatus 20. For example, hundreds or thousands of physical machines 40 may be connected.

  The user terminal 10 is a computer terminal connected to the computer resource providing apparatus 20 and the plurality of physical machines 40 via a network, and uses 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 20 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 20 in response to the transmitted provision request. It can be used by connecting to the machine 40 via a network. Here, one user terminal 10 is shown and described, but any number of user terminals 10 of any number of users may be connected to the computer resource providing system 1.

  The computer resource providing device 20 is a computer device that causes the user terminal 10 to use computer resources of a plurality of physical machines 40 connected via a network. The computer resource providing apparatus 20 includes a usage status storage unit 21 and a physical machine lending unit 22.

  The usage status storage unit 21 stores usage status information indicating the usage status of the plurality of physical machines 40. FIG. 2 is a diagram illustrating a data example of usage status information stored in the usage status storage unit 21. The usage status information includes information in which a lending destination is associated with each machine ID (identifier) that identifies the physical machine 40. The lending destination is information for identifying the user from whom the corresponding physical machine 40 is lent, and when the physical machine is lent to the user, the user ID, which is identification information for identifying the user, is associated, When it is not lent, information indicating “vacant” is associated. Here, the physical machine 40 with the machine ID “M1” is lent to the user with the user ID “U1”, and the physical machine 40 with the machine ID “M2” is in an empty state. It is shown.

  When the physical machine lending unit 22 receives a physical machine provision request from the user terminal 10, the physical machine lending unit 22 lends the physical machine 40 in an empty state to the user terminal 100. Here, lending means that identification information (for example, IP address) of the physical machine 40 to be used by the user terminal 10 that is the transmission source of the provision request is transmitted to the user terminal 10, and the user terminal 10 It is set to permit connection from 10 and to permit operation with administrator authority. The physical machine provided by the computer resource providing apparatus 20 is assigned a machine type according to the performance of the physical machine. The provision request transmitted from the user terminal 10 includes the machine type requested by the user. It is assumed that the information shown is included. For example, when receiving a physical machine provision request from the user terminal 10, the physical machine lending unit 22 provides a provision request among a plurality of physical machines 40 based on the usage status information stored in the usage status storage unit 21. It is determined whether there is a free physical machine 40 to which a machine type corresponding to the number is assigned. If it is determined that there is a free physical machine 40, the user terminal 10 is made to use the physical machine 40. .

  The machine management support device 30 is a computer device that manages a plurality of physical machines 40 provided to the user terminal 10 by assigning them to predetermined machine types, and includes a performance value information storage unit 31, a score reference information storage unit 32, and the like.

I have.

  The performance value information storage unit 31 stores performance value information in which a performance value is associated with each item indicating the hardware performance of the physical machine 40 for each of the plurality of physical machines 40 lent to the user. Here, the performance value includes a value indicating one or more of CPU (Central Processing Unit) performance, memory performance, and storage performance. FIG. 3 is a diagram illustrating a data example of performance value information stored in the performance value information storage unit 31. The machine ID is identification information that identifies the physical machine 40. The performance value is a value indicating the hardware performance of the corresponding physical machine 40. Here, the number of CPU cores, the CPU clock (GHz), the memory size (GB), the number of memory modules, and the storage size (GB). ) And a NIC (Network Interface Card) speed (Mb / s). In addition, the value of an arbitrary item indicating the hardware performance of the physical machine 40 may be associated.

  The score reference information storage unit 32 stores score reference information in which the performance value of the physical machine 40 is associated with the score corresponding to the performance value. Based on the score reference information, the performance value of the physical machine 40 is converted into a score. FIG. 4 is a diagram illustrating a data example of the score reference information for the number of CPU cores stored in the score reference information storage unit 32. FIG. 5 is a diagram illustrating a data example of the CPU clock score reference information stored in the score reference information storage unit 32. FIG. 6 is a diagram illustrating a data example of the score reference information of the memory size stored in the score reference information storage unit 32. FIG. 7 is a diagram illustrating a data example of the score reference information of the memory module stored in the score reference information storage unit 32. In addition, the point reference information storage unit 32 stores point reference information indicating points according to the performance value of each item included in the performance value information.

  The score information storage unit 33 stores score information in which a score corresponding to a performance value indicating the hardware performance of the physical machine 40 is associated with each of the plurality of physical machines 40 lent to the user. FIG. 8 is a diagram illustrating a data example of the score information stored in the score information storage unit 33. Thus, by scoring the performance of the physical machine 40, it becomes easy to compare with the performance of other machines.

  In the deviation value information storage unit 34, for each of the plurality of physical machines 40 lent to the user, a deviation in which a deviation value based on the population of the plurality of physical machines is associated with the number of points according to the performance of the physical machine 40 Value information is stored. FIG. 9 is a diagram illustrating a data example of the deviation value information stored in the deviation value information storage unit 34. By using such a deviation value, it is possible to compare the relative performance levels of the individual physical machines 40 including all of the plurality of physical machines 40 lent to the user as a population.

  The reference value information storage unit 35 stores reference value information in which a reference value of a predetermined performance value is associated with a machine type corresponding to the reference value. The reference value information is, for example, information in which a reference value of a deviation value of a predetermined performance value is associated with a machine type corresponding to the reference value. FIG. 10 is a diagram illustrating a data example of the reference value information stored in the reference value information storage unit 35. Here, for each machine type ID that is identification information for identifying a machine type, a reference value (deviation value) of the machine type is associated with each item indicating the performance of the physical machine 40. The reference value is a threshold value of a deviation value indicating whether to assign to a corresponding machine type. When the deviation value of the performance value of the physical machine 40 is equal to or greater than all the reference values of a plurality of items associated with the machine type, the physical machine 40 is assigned to the machine type.

  Here, when the user requests provision of three physical machines according to the three functions of the web server, application server, and DB server, it is considered that the performance required of the physical machine may differ depending on the functions. . For example, in a physical machine used as a web server, it is desirable that the communication speed and the processing speed be high performance, but a general storage capacity may be sufficient. On the other hand, for a physical machine used as a DB server, for example, a large storage capacity is desirable, but a general processing speed may be sufficient. Alternatively, even for the same function, the required performance differs depending on the number of accesses to the web server, the amount of data stored in the DB server, and the like. Therefore, a machine type corresponding to such an application is assigned to each of the plurality of physical machines 40 in advance. In the computer resource providing system 1 of the present embodiment, a request for providing the physical machine 40 with such a machine type is received, and the physical machine 40 to which the machine type is assigned is provided.

  In the example of this figure, the reference value of the machine type with the machine type ID “T1” is lower than all the reference values of the machine type with the machine type ID “T2”, and the machine type ID is “T1”. The machine type is a machine type subordinate to the machine type whose machine type ID is “T2”. The standard value of the machine type whose machine type ID is “T36” is average in the number of CPU cores, CPU clock, storage size, and NIC speed, but is higher than other machine types in the memory size and the number of memory modules. A value is associated. The reference value of the machine type with the machine type ID “T52” is average in memory size, number of memory modules, storage size, and NIC speed, but higher in the number of CPU cores and CPU clock than other machine types. A value is associated. The standard value of the machine type whose machine type ID is “T78” is that the storage size and NIC speed are average, but the number of CPU cores, CPU clock, memory size, and number of memory modules are higher than other machine types. A high value is associated. The reference value for the machine type with the machine type ID “T83” is associated with a low value for the CPU core number, CPU clock, memory size, memory module number, and NIC speed, but a high value for the storage size. It is attached. Here, according to the number of physical machines 40 provided to the user, for example, about 100 machine types can be determined in advance.

  The machine type storage unit 36 stores machine type information in which a plurality of physical machines 40 are associated with a machine type indicating a type corresponding to the performance of the physical machine. FIG. 11 is a diagram illustrating a data example of machine type information stored in the machine type storage unit 36. In this example, the machine type IDs “T1”, “T2”, and “T52” are assigned to the physical machine 40 having the machine ID “M1”. As described above, a plurality of machine types can be assigned to one physical machine 40. When a plurality of machine types are assigned to one physical machine 40, for example, a plurality of machine type IDs are assigned ", ”Can be associated with each other. It is shown that the machine type IDs “T1” and “T83” are assigned to the physical machine 40 with the machine ID “M2”.

  Returning to FIG. 1, the input unit 37 accepts input of performance value information of the physical machine 40 and causes the performance value information storage unit 31 to store the input performance value information. For example, the input unit 37 includes input devices such as a keyboard and a mouse. When a provider providing a computer resource providing service connects a new physical machine 40 to be lent to a user to the computer resource providing apparatus 20, the input unit 37 The performance value information of the physical machine 40 is input to the input unit 37. The input unit 37 causes the performance value information storage unit 31 to store the input performance value information.

  The deviation value calculation unit 38 calculates, for each of the plurality of physical machines 40, a score corresponding to the performance value associated with the physical machine, calculates a deviation value based on the calculated score, and obtains deviation value information. It is generated and stored in the deviation value information storage unit 34. Specifically, the deviation value calculation unit 38 reads the performance value information stored in the performance value information storage unit 31 and the score reference information stored in the score reference information storage unit 32, and uses it as the performance value information. A score conversion process is performed in which the score corresponding to the performance value of each item included is determined, and score information in which the score corresponding to the performance value is associated with the machine ID is stored in the score information storage unit 33. Further, the deviation value calculation unit 38 reads the score information corresponding to all the physical machines 40 stored in the performance value information storage unit 31, and the deviation value of each physical machine 40 using all the score information as a population. Is calculated for each item to generate deviation value information, and a deviation value calculation process for storing the generated deviation value information in the deviation value information storage unit 34 is performed.

  The deviation value calculation unit 38 may perform such point conversion processing and deviation value calculation processing, for example, periodically (for example, at intervals of one day), or when a calculation request is input from a provider. May be. Alternatively, when the performance value information of the new physical machine 40 is input to the input unit 37 and the new performance value information is stored in the performance value information storage unit 31, the deviation value calculation unit 38 performs the score conversion process and the deviation value. Calculation processing can also be performed. According to this, when a new physical machine 40 is added to the machine pool, it is possible to recalculate the entire deviation value including the performance value of the physical machine 40 and assign the machine type according to the situation. Can be assigned an appropriate machine type.

  The machine type determination unit 39 determines, for each physical machine 40, a machine type corresponding to the physical machine 40 based on performance value information and reference value information corresponding to the physical machine 40, and generates machine type information. And stored in the machine type storage unit 36. Here, the machine type determination unit 39 determines the machine type corresponding to the physical machine 40 based on the deviation value information based on the performance value information of the physical machine 40 and the reference value information. Specifically, the machine type determination unit 39 reads the reference value information stored in the reference value information storage unit 35, and outputs one piece of deviation value information stored in the deviation value information storage unit 34 for each machine ID. It is read out one by one, and it is determined whether or not the deviation value of each item included in the read deviation value information is equal to or greater than a threshold value determined for each machine type included in the reference value information.

Here, when the machine type determination unit 39 determines that all the deviation values of each item included in the deviation value information are equal to or greater than the threshold value determined for the machine type included in the reference value information, the machine ID is assigned to the machine ID. Determine that a machine type is assigned. If it is determined that the deviation value of one or more items among the items included in the deviation value information is not equal to or greater than the threshold value defined for the machine type included in the reference value information, it is determined that the machine type is not assigned to the machine ID. To do. The machine type determination unit 39 determines whether or not to assign each of a plurality of machine types included in the reference value information to one machine ID, and sets the machine type ID of the machine type determined to be assigned as the machine ID. Is generated, and the generated machine type information is stored in the machine type storage unit 36.
The physical machine 40 is a computer resource lent to the user.

Next, an exemplary operation of the machine management support apparatus 30 according to the present embodiment will be described with reference to the drawings. FIG. 12 is a flowchart illustrating an operation example of the machine management support apparatus 30 according to the present embodiment.
When receiving the input of performance value information, the input unit 37 stores the input performance value information in the performance value information storage unit 31 (step S1). When new performance value information is stored in the performance value information storage unit 31, the deviation value calculation unit 38 reads out the performance value information stored in the performance value information storage unit 31 and stores it in the score reference information storage unit 32. The score reference information is read out, the score corresponding to the performance value indicated in the performance value information is determined to generate score information, and the generated score information is stored in the score information storage unit 33 (step S2).

  Further, the deviation value calculation unit 38 reads out the point information stored in the point information storage unit 33, and the physical information of all the physical machines 40 stored in the point information storage unit 33 as a population. The deviation value of the machine 40 is calculated to generate deviation value information, and is stored in the deviation value information storage unit 34 (step S3). The machine type determination unit 39 reads the reference value information stored in the reference value information storage unit 35 and the deviation value information stored in the deviation value information storage unit 34, and reads one deviation value. The information is compared for each machine type included in the reference value information (step S4). The machine type determination unit 39 determines whether or not the deviation values of the plurality of items included in the deviation value information are greater than or equal to the reference value indicated in the machine type reference information, and the deviations of the plurality of items included in the deviation value information If it is determined that the deviation value of at least one of the values is not equal to or greater than the reference value indicated in the machine type reference information (step S5: NO), the process proceeds to step S7.

  On the other hand, if it is determined that all of the deviation values of the plurality of items included in the deviation value information are greater than or equal to the reference value indicated in the machine type reference information (step S5: YES), the machine type is determined by the deviation value information. It is stored in the machine type storage unit 36 in association with the machine ID shown (step S6). If the machine type determination unit 39 has not performed comparison processing with all machine types for the deviation value information of one physical machine 40 (step S7: NO), the process returns to step S4. When the deviation value information of one physical machine 40 is compared with all the machine types (step S7: YES), the machine type determination process is not performed on the deviation value information of all the physical machines 40 (step S7: YES). Step S8: NO), it returns to step S4. When machine type determination processing is performed for deviation value information of all physical machines 40 (step S8: YES), the processing ends.

  When the computer resource providing apparatus 20 receives a computer resource provision request specifying a machine type from the user terminal 10, the physical machine lending unit 22 stores the machine type information stored in the machine type storage unit 36, and the usage status. The usage status information stored in the storage unit 21 is read out. Then, the physical machine lending unit 22 detects an empty physical machine 40 among the physical machines 40 to which the machine type designated by the provision request is assigned, and sends the detected physical machine 40 to the user terminal 10. Lend. In this way, it is possible to efficiently manage a large number of physical machines 40 having different performances and provide an appropriate physical machine 40 according to a user request.

  In the present embodiment, an example in which performance value information of a new physical machine 40 is input from the provider to the input unit 37 of the machine management support apparatus 30 has been described. The input of performance value information may be received by reading a file including the performance value of the machine 40 (for example, a CSV (Comma Separated Values) file). Alternatively, for example, when it is detected that a new physical machine 40 is connected to the computer resource providing apparatus 20, a command that is a performance value information acquisition request is transmitted to the physical machine 40, and the performance value information is automatically acquired. You may make it do.

  In the present embodiment, the reference value information storage unit 35 stores reference value information in which a reference value of a deviation value of a performance value and a machine type corresponding to the reference value are associated with each other. The performance value of 40 is converted into a score, a deviation value based on the score is calculated, and the machine type according to the deviation value is determined. However, the reference value information according to the performance value is stored in the reference value information storage unit 35. The machine type can also be determined directly from the performance value without storing the score.

  Further, in the present embodiment, when new performance value information is input to the input unit 37, an example will be described in which the deviation value calculation process and the machine type determination process are recalculated based on the point information of all physical machines 40. However, the deviation value calculation process and the machine type determination process may be performed only for newly input performance value information. In addition, the deviation value and the machine type history are stored, and when the deviation of the physical machine 40 provided to the user is changed and the machine type is changed, the fee according to the changed machine type is used. Control such as providing the physical machine 40 can also be performed.

In addition, the machine arrangement of the physical machines 40 distributed in a plurality of locations can be optimized according to the machine type determined according to the present embodiment.
Further, when the physical machine lending unit 22 of the computer resource providing apparatus 20 detects the physical machine 40 according to the provision request from the user, there are a plurality of free physical machines 40 to which the machine type designated by the provision request is assigned. If it exists, the physical machine 40 to which the machine type with the lowest reference value is assigned can be detected as the physical machine 40 to be provided. For example, when the provision request for the machine type “T1” is received, the machine “M1” to which the machine types “T1” and “T2” are assigned and the machine type “T1” are assigned to “T2”. If both the machine “M2” to which the machine is not assigned are free, the computer “M2” can be preferentially provided to efficiently operate the computer resources. However, if the machine “M2” has already been rented and only the machine “M1” is available, the machine “M1” may be provided. This can prevent a situation where computer resources are exhausted and cannot be provided when a provision request is received from a user.

  Further, when the physical machine lending unit 22 of the computer resource providing apparatus 20 detects the physical machine 40 according to the provision request from the user, a machine type that is permitted to be provided according to the authority of the user is determined in advance. Only the physical machine 40 of the selected machine type may be provided. Alternatively, for example, a radar chart in which performance values (deviation values) corresponding to items indicating performance such as the number of CPU cores, the number of CPU clocks, the memory size, and the number of memory modules are plotted is generated, and the values plotted on the radar chart are Whether or not the provision is permitted may be determined according to the size of the area of the regions connected by the straight line. In this case, an allowable value of the area of the radar chart that is allowed to be provided according to the authority of the user is determined, and compared with the radar chart according to the performance value of the physical machine 40, the performance within the area determined for each authority. Only a certain physical machine 40 can be lent. Thereby, the physical machine 40 according to the authority can be provided.

  As described above, according to the present embodiment, a predetermined machine type can be efficiently and uniformly allocated to a large number of physical machines 40 to be provided to a user based on a certain standard. That is, if the machine type assignment is performed manually, a human cost is generated and an error or a bias may occur in the machine type assignment. On the other hand, according to the present embodiment, it is possible to assign machine types without causing human costs and without bias. Thereby, the management cost of the physical machine 40 for the provider of the computer resource providing service can be reduced. On the other hand, it is possible to provide physical machines 40 according to machine types assigned to users under uniform conditions, and it is expected to improve customer satisfaction by providing a stable computer resource providing service.
