Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
<First Embodiment>
First, an outline of a resource providing system 1 according to the first embodiment of the present invention will be described with reference to FIG. The resource providing system 1 of this embodiment includes a plurality of cloud service systems (first cloud service system 1000 and second cloud service system 2000) and a machine pool 3000. The cloud service system includes a plurality of virtualization apparatuses (physical machines) that virtualize their computer resources and activate a virtual machine. Also, the cloud service system provides computer resources by causing a user terminal to use a virtual machine started by a virtualization apparatus included in the cloud service system in response to a computer resource provision request from the user terminal. The machine pool 3000 is a computer group to which virtualization devices that do not belong to any cloud service system belong.

  When there is a surplus in the computer resources of the virtualization devices belonging to the cloud service system, the cloud service system releases the surplus virtualization devices and makes them belong to the machine pool 3000. On the other hand, when its own computer resource is insufficient, the virtualization apparatus is acquired from the machine pool 3000, and the acquired computer resource of the virtualization apparatus is provided. In this way, it becomes possible to share surplus resources among a plurality of cloud service systems and to allow computer resources to be mutually interchanged. As a result, in each cloud service system, it is possible to provide computer resources even when there is a request for providing computer resources that exceeds the amount of computer resources prepared in advance. Also, since the total amount of computer resources that can be provided in each cloud service system will exceed the computer resources that each cloud service system prepares independently, leveling fluctuations in provision requests from users over time It is possible to enjoy the benefits of scale.

  As shown in FIG. 2A, each conventional cloud service system has its own computer resources, and only the computer resources that are uniquely prepared can be used. That is, in each cloud service system, it is necessary to prepare in advance computer resources that can provide computer resources in response to computer resource provision requests irregularly performed by a plurality of users. For this reason, in the time zone when the prepared computer resource has a surplus, the surplus resource remains surplus, and it may not be said that the prepared computer resource can be used effectively. On the other hand, in the resource providing system 1 according to the present embodiment, as shown in FIG. 2 (b), a plurality of cloud service systems exchange computer resources via a machine pool. When there is a surplus resource, the surplus resource can be used in another cloud service system to enable effective use of computer resources.

  Here, since each cloud service system is a different service, it is important to isolate each other's network and ensure security so that information leakage and unauthorized access between cloud service systems will not occur. . Thus, each cloud service system is formed with a physically or logically different network segment. Furthermore, when moving a virtualization apparatus between cloud service systems, the virtual device is always moved after belonging to the machine pool 3000, and computer resources are not directly transferred between cloud service systems. In this way, the independence of each cloud service system is maintained. Here, “movement of the virtualization device” is realized by switching the network segment to which the virtualization device belongs, as will be described later.

  Furthermore, when releasing a virtualization apparatus from each cloud service system to the machine pool 3000, cleanup processing such as disk cleanup, maintenance, and operation test is performed on the released virtualization apparatus. When the released virtualization apparatus is acquired by another cloud service system, it is acquired after performing such a cleanup process. In this way, it is possible to prevent information remaining when used in other cloud service systems from remaining in computer resources that move between cloud service systems. In this way, information leakage and unauthorized access between cloud service systems is prevented. In addition, the physical machine group that constitutes each cloud service system by network virtualization technology such as VLAN (Virtual Local Area Network) has an independent configuration in terms of network security. In addition, the information is not leaked or tampered with in a straddled form. As a result, each cloud service system has a level of security that can be provided to a company as a so-called private cloud.

<Configuration>
Next, a specific terminal configuration example that provides such a resource providing system 1 will be described with reference to FIG. Here, a network is formed by a computer group of the first cloud service system 1000, the second cloud service system 2000, and the machine pool 3000.

  The first cloud service system 1000 includes a cloud management device 1100, a cluster management device 1200-1, a cluster management device 1200-2, a virtualization device 1300-1, a virtualization device 1300-2, and virtualization. Device 1300-3 belongs. The second cloud service system 2000 includes a cloud management device 2100, a cluster management device 2200-1, a virtualization device cluster management device 2200-2, a virtualization device 2300-1, and a virtualization device 2300-2. The virtualization apparatus 2300-3, the virtualization apparatus 2300-4, and the virtualization apparatus 2300-5 belong. A machine pool management apparatus 3100, a cleanup apparatus 3200, a virtualization apparatus 3300-1, a virtualization apparatus 3300-2, and a virtualization apparatus 3300-3 belong to the machine pool 3000. Here, since the apparatuses having the same names have the same configuration, when there is no need to individually explain them, they will be described as a cloud management apparatus 1100, a cluster management apparatus 1200, and a virtualization apparatus 1300, respectively. The virtualization apparatus (the virtualization apparatus 1300, the virtualization apparatus 2300, and the virtualization apparatus 3300) included in the resource providing system 1 is one of the first cloud service system 1000, the second cloud service system 2000, and the machine pool 3000. Each of the cloud management device 1100 in the cloud service system and the machine pool management device 3100 in the machine pool 3000 stores the identification information of the virtualization device assigned to itself.

  Next, with reference to FIG. 4, the function of each computer apparatus that provides the resource providing system 1 will be described. The user terminal 500 is a computer device that receives computer resources provided by the first cloud service system 1000. The user terminal 500 has an Internet browser function and communicates with the cloud management apparatus 1100 and the like. The user terminal 500 transmits a computer resource provision request to the cloud management apparatus 1100 in accordance with operation information input from the user. In addition, the user terminal 500 receives the IP address of the virtualization apparatus 1300 provided to itself in response to the computer resource provision request from the cloud management apparatus 1100. The user terminal 500 accesses the virtualization apparatus 1300 provided to itself using the received IP address as a destination, and uses the virtual machine of the virtualization apparatus 1300-N. For example, the user terminal 500 can build a web server or the like on a virtual machine of the virtualization apparatus 1300 provided to the user terminal 500 and publish a web service on the Internet. Here, a single user terminal 500 is illustrated and described as a computer device that makes a computer resource provision request. However, each cloud service system receives a provision request from a plurality of user terminals, provide. Here, the user terminal 500 communicates with the cloud management apparatus 1100 and the like by the function of the Internet browser. However, the user terminal 500 may communicate with another dedicated application. The cloud service system may provide computer resources in response to a computer resource provision request transmitted from a service providing apparatus that provides an application service via a network, for example. As described above, the cloud service system provides computer resources in response to a computer resource provision request transmitted from a program that operates in various computer devices connected via a network.

  The cloud management apparatus 1100 is a computer apparatus that receives a computer resource provision request transmitted from the user terminal 500 and manages the cluster management apparatus 1200 and the virtualization apparatus 1300 belonging to the first cloud service system 1000. The cloud management apparatus 1100 includes a provision request receiving unit 1110, a resource amount storage unit 1120, a determination unit 1130, a resource provision unit 1140, an allocation request unit 1150, and a release request unit 1160.

  The provision request receiving unit 1110 receives a computer resource provision request transmitted from the user terminal 500. Here, the provision request received by the provision request receiving unit 1110 includes a user ID for identifying the user terminal 500 that has transmitted the provision request, a computer resource provision request period, a computer resource provision request amount, and the like. The computer resource provision request period includes, for example, information indicating a start date and time and an end date and time when the user requests provision of computer resources. The computer resource provision request amount includes, for example, information indicating the number of units based on a predetermined computer resource unit. For example, the computer resource provision unit is a unit determined by the capability value of the computer resource. For example, a virtual machine having a CPU performance of 2.6 GHz, a memory capacity of 2 GB, and a disk capacity of 500 GB is taken as one unit. For example, the first cloud service system provides computer resources in response to a provision request from the user terminal 500 with the number of units determined in advance as to the user who transmits the provision request as an upper limit.

  The resource amount storage unit 1120 stores the amount of computer resources allocated to the first cloud service system 1000 in the network and the amount of computer resources provided to a plurality of user terminals 500. . The allocated amount of computer resources is the total amount of computer resources of a plurality of virtualization apparatuses 1300 belonging to the first cloud service system 1000. The provision amount of the computer resource is updated and stored when the resource provision unit 1140 provides the computer resource to the user terminal 500. The allocated amount and the provided amount are represented by the above-described computer resource unit.

  Whether the determination unit 1130 can provide the computer resource corresponding to the provision request amount included in the provision request received by the provision request reception unit 1110 from among the computer resources allocated to the first cloud service system 1000. Determine whether or not. For example, the determination unit 1130 compares the difference between the allocation amount and the provision amount stored in the resource amount storage unit 1120 with the provision request amount included in the provision request transmitted from the user terminal 500, and determines the allocation amount. When the difference from the provision amount is larger than the provision request amount, it is determined that the provision is possible. On the other hand, when the difference between the allocated amount and the provision amount is smaller than the provision request amount, it is determined that the provision is not possible.

  When the determination unit 1130 determines that the computer resource can be provided, the resource providing unit 1140 includes a computer resource corresponding to the amount of provision request among the plurality of virtualization apparatuses 1300 belonging to the first cloud service system 1000. It is determined that the computer resource of the virtualization apparatus 1300 having the available space is provided to the user terminal 500. The resource providing unit 1140 transmits to the user terminal 500 an IP (Internet Protocol) address that identifies a computer resource determined to be provided. The user terminal 500 connects to the virtualization apparatus 1300 using the transmitted IP address as a destination, and uses the provided computer resources of the virtualization apparatus 1300.

  The allocation request unit 1150 transmits a virtual device allocation request to the resource transaction device 100 when the determination unit 1130 determines that the computer resource cannot be provided. The allocation request includes an allocation request amount indicating a computer resource unit for which the allocation request unit 1150 requests allocation. The allocation request amount is, for example, a shortage of the provision request amount with respect to the difference between the allocation amount and the provision amount. Here, when the virtualization apparatus 1300 is allocated in response to the allocation request transmitted by the allocation request unit 1150, the resource providing unit 1140 provides computer resources to the user terminal 500 from the allocated virtualization apparatus 1300. .

  The release request unit 1160 compares the difference between the allocation amount and the provision amount stored in the resource amount storage unit 1120 with the provision request amount, and determines the computer resource among the virtualization apparatuses 1300 allocated to itself. The virtualization apparatus 1300 that is not provided within the period is detected as a surplus resource, and the resource transaction apparatus 100 is requested to release the detected surplus resource.

  The cluster management device 1200 is a computer device that manages a plurality of virtualization devices 1300 belonging to the first cloud service system 1000 for each predetermined unit (cluster). For example, the cluster management device 1200-1 manages the virtualization device 1300-1 and the virtualization device 1300-2, and the cluster management device 1200-2 manages the virtualization device 1300-3 and the virtualization device 1300-4. to manage. Here, in the management of the virtualization apparatus 1300, for example, processing for monitoring the resource status of the virtualization apparatus 1300 is performed. For example, when the cluster management apparatus 1200 notifies the IP address of the virtualization apparatus 1300 corresponding to the computer resource provided to the user terminal 500 by the resource providing unit 1140 of the cloud management apparatus 1100, any one of the plurality of virtualization apparatuses 1300 Whether to provide the computer resources of the virtualization apparatus 1300 is determined based on the resource status, load status, etc. of the virtualization apparatus 1300 belonging to itself.

The plurality of virtualization apparatuses 1300 are computer apparatuses having a function of virtualizing their own computer resources. The virtualization apparatus 1300 virtually divides its own computer resource and starts a virtual machine on the divided computer resource. Here, the cloud service system prepares in advance an image that is information including a plurality of types of OS (Operating System) and server programs and application programs that operate on the OS, and responds to user requests. Is deployed on the virtual machine and provided to the user terminal 500 so as to be usable. As software for providing such a virtual machine, for example, Xen (registered trademark) can be applied.
The second cloud service system 2000 has the same configuration as the first cloud service system 1000 described above, and each of the cloud management device 2100, the cluster management device 2200, and the virtualization device 2300 has the same name provided in the resource transaction device 100. The configuration is the same as that of the computer apparatus.

The machine pool 3000 is a computer group to which computer devices that do not belong to any cloud service system among a plurality of cloud service systems connected to the network belong.
The machine pool management apparatus 3100 manages computer apparatuses that do not belong to any cloud service system. For example, when the machine pool management device 3100 receives a management request for a computer device from the resource transaction device 100, the machine pool management device 3100 stores the identification information of the computer device identified by the management request. Here, the computer device identification information stored as a management target by the machine pool management device 3100 is an unidentified computer device that is not assigned to any of a plurality of cloud service systems among the computer devices connected to the network. This is assigned computer resource identification information.

When the cleanup device 3200 receives the cleanup request transmitted from the resource transaction device 100, the cleanup device 3200 performs the cleanup process of the virtualization device 1300 identified by the received cleanup request. The cleanup process includes, for example, disk cleanup of the virtualization apparatus 1300, disk maintenance, self-test, and the like. The disk cleanup is, for example, a process of storing 0 (zero) in all the storage bits of the disk. Disk maintenance is, for example, processing for writing to a disk and determining whether a write error occurs. Such a cleanup process may take 10 hours, for example, depending on the capacity of the disk.
The virtualization apparatus 3300 has the same configuration as the computer apparatus with the same name belonging to the first cloud service system 1000.

  The resource transaction device 100 is a computer device that controls the allocation of computer devices between computer groups, and includes a request receiving unit 110, a request schedule storage unit 120, a request schedule management unit 130, and a cloud state management unit 140. A resource allocation schedule storage unit 150, a resource allocation schedule management unit 160, a schedule matching unit 170, and a resource allocation unit 180.

  The request reception unit 110 receives a virtual device allocation request or release request transmitted from the resource transaction device 100. When the request reception unit 110 receives the allocation request or the release request, the schedule matching unit 170 detects surplus resources according to the resource status of each cloud service system, and the resource allocation unit 180 allocates the detected surplus resources. Assigned to the cloud service system that sent the request. Here, each part of the resource transaction apparatus 100 may operate when the request receiving unit 110 receives an allocation request or a release request, or may operate at regular intervals, or both. May be performed.

  The request schedule storage unit 120 stores provision requests for which provision of computer resources has not started among the provision requests transmitted to each cloud service system in the network. FIG. 5 is a diagram illustrating an example of the provision request data stored in the request schedule storage unit 120. As described above, the provision request includes the user ID corresponding to the user terminal 500 that has transmitted the provision request, the computer resource provision start date and time, the end date and time, and the provision request amount. It is stored in association with a provision request ID for identifying the provision request. The request schedule storage unit 120 stores a provision request for each cloud service system in the network.

  Based on the provision request stored in the request schedule storage unit 120, the request schedule management unit 130 calculates a predicted value of the increase / decrease amount of the computer resource provision amount for each fixed time for each cloud service system. For example, FIG. 6 is a diagram illustrating a data example of the predicted value of the provision amount for each cloud service system calculated by the request schedule management unit 130. In this example, in the first cloud service system (cloud ID “1”), after one minute (00:01 minutes), the amount of computer resources provided increases by 10 units compared to the current time (00:00 minutes). 2 minutes later (00:02 minutes), the amount of computer resources provided increases by 15 units compared to the present time (00:00 minutes). Here, when the request schedule management unit 130 calculates the predicted value, it is calculated by adding the provision request amount according to the provision request stored in the request schedule storage unit 120 to the present provision amount. Alternatively, the history information indicating the transition of the requested request amount is stored, and the predicted value of the increase / decrease amount of the computer resource provision amount is calculated in accordance with fluctuations in the day of the week, the time zone, the number of users, and the like. May be.

  The cloud state management unit 140 stores the resource amount storage unit of the cloud management device in each cloud service system connected in the network (the resource amount storage unit 1120 of the cloud management device 1100 in the case of the first cloud service system 1000). The stored allocation amount and provision amount of the computer resource are read, and the usage status information is stored in its own storage area.

  FIG. 7 is a diagram illustrating a data example of usage status information that the cloud state management unit 140 stores in its own storage area. Here, each cloud ID for identifying a cloud service system is associated with information indicating the amount of computer resources allocated to the cloud service system and the amount of computer resources actually provided to the user terminal. Remembered. Here, assuming that the cloud ID of the first cloud service system 1000 is 1 and the cloud ID of the second cloud service system 2000 is 2, 256 units of computer resources are allocated to the first cloud service system 1000. It shows that 150 computer resources of the allocated computer resources are provided to the user terminal. That is, in the first cloud service system 1000, the surplus resource that is the difference between the allocated amount and the provided amount is 116 units, and it is possible to provide computer resources in response to a provision request for 116 units from the current state. Is possible. In the second cloud service system 2000, 128 units of computer resources are allocated, and 105 units of the allocated computer resources are provided to the user terminal.

  The resource allocation schedule storage unit 150 stores a resource allocation schedule in which a cloud service system to which each computer device connected to the network is allocated is associated at regular intervals. The resource allocation schedule storage unit 150 identifies unassigned computer resources that identify computer resources belonging to the machine pool 3000 that are not assigned to any cloud service system among computer resources connected to the network. Information is stored.

  The resource allocation schedule management unit 160 calculates a required time (si) for every fixed time required for the allocation of the virtualization apparatus based on the change in the network configuration based on the resource allocation schedule stored in the resource allocation schedule storage unit 150. calculate. FIG. 8 is a diagram illustrating a data example of required time required for allocation of a virtualization apparatus calculated by the resource allocation schedule management unit 160 for each cloud ID and for each number of computer resource units.

  Based on the predicted value of the amount of computer resource provided calculated by the request schedule management unit 130 and the usage status information calculated by the cloud state management unit 140, the schedule matching unit 170 is configured for each cloud service system at regular intervals. The surplus resource amount is predicted, and a time point (t1, t2,..., Tn) at which the surplus resource amount becomes equal to or less than a specified value is detected. Here, the specified value of the surplus resource amount is, for example, a threshold value determined according to the allocated amount for each cloud service system, and responds to a provision request from the user terminal 500 when the surplus resource amount falls below that value. It is a value indicating that there is a possibility that the computer resources for running out are insufficient. For example, if the allocation amount of computer resources for a certain cloud service system is 256 units, 64 units corresponding to a quarter thereof are determined as the prescribed value. The schedule matching unit 170 uses an estimated value of the computer resource provision amount per fixed time calculated by the request schedule management unit 130 as a surplus resource that is the difference between the allocation amount and provision amount calculated by the cloud state management unit 140. When the number increases according to, a time point (t1, t2,... Tn) at which the surplus resource becomes less than the specified value is detected. The schedule matching unit 170 also determines that the difference between each time point (t1, t2,... Tn) when the surplus resource becomes less than the specified value and the current time point (T) is necessary for the allocation of the virtualization apparatus. It is determined whether it is less than time (si).

  The resource allocation unit 180 determines that the schedule matching unit 170 determines that the difference between any time point (ti) when the surplus resource is less than the specified value and the current time point (T) is required for allocation of the virtualization apparatus (si). When it is determined that the number is less than (), the allocation processing of the virtualization apparatus is performed. In the allocation process of the virtualization apparatus, the schedule matching unit 170 determines the time required for allocation of the virtualization apparatus as the difference between any time point (ti) when the surplus resource becomes less than the specified value and the current time period (T). (Si) The virtual network management apparatus 200 is made to switch the network segment so that the virtualization apparatus belonging to the machine pool 3000 is allocated to the cloud service system determined to be less than (si).

  Here, the resource allocation unit 180 performs unallocated computer resource identification stored in the resource allocation schedule storage unit 150 in response to an allocation request transmitted from the cloud management apparatus 1100 when performing the allocation process of the virtualization apparatus. The information is read, and the virtualization apparatus corresponding to the read unallocated computer resource identification information is allocated to the resource providing apparatus 1100 that is the request source of the allocation request. On the other hand, when performing the release processing of the virtualization apparatus, the virtual network management apparatus 200 switches the network segment in response to the release request transmitted from the resource providing apparatus 1100, and then the surplus corresponding to the release request. Identification information for identifying a resource is stored in the resource allocation schedule storage unit 150 as unallocated computer resource identification information.

  The virtual network management device 200 switches network segments based on an instruction from the resource allocation unit 180 of the resource transaction device 100. For example, the network segment is switched from the IP address of the virtualization device 1300 based on the network segment assigned to the first cloud service system 1000 to the network segment assigned to the second cloud service system 2000. This is done by reassigning the IP address based on it. Here, for example, when a firewall or the like is installed for each network segment, the virtual network management apparatus 200 switches setting values in the firewall. Further, the network segments may be securely separated by using network virtualization technology such as VLAN, overlay network, VPN (Virtual Private Network). For example, when switching to this network segment using a network switch having a VLAN function, the identification tag received by the virtualization apparatus 1300 is changed from the identification tag assigned to the first cloud service system 1000 to the first tag. The virtual network management apparatus 200 switches the setting value of the network switch so as to change to the identification tag assigned to the second cloud service system 2000.

<Operation example: Resource allocation>
Next, with reference to FIG. 9, an operation example in which the resource providing system 1 according to the present embodiment allocates a virtualization apparatus from the machine pool 3000 to the cloud service system will be described. Here, the allocation process of the virtualization apparatus performed by the resource transaction apparatus 100 at regular intervals will be described. The resource transaction apparatus 100 allocates a virtualization apparatus from the machine pool 3000 to a cloud service system that lacks computer resources according to the status of the cloud service system connected to the network.

  The request schedule management unit 130 reads the provision request for each cloud service system stored in the request schedule storage unit 120, and calculates a predicted value of the provision request amount for each fixed time according to the provision request as shown in FIG. (Step S1). The cloud state management unit 140 reads the provided amount of the computer resource that each cloud service system provides to the user terminal at the present time (T) from the cloud management device of each connected cloud service system, as shown in FIG. Such usage information is generated and stored (step S2).

  The resource allocation schedule management unit 160 provides each cloud service system as shown in FIG. 6 based on the difference between the provision request amount stored in the request schedule storage unit 120 and the allocation amount of each cloud service system. Calculate the predicted value of the quantity. The schedule matching unit 170 performs a predetermined time based on the predicted value of the requested request amount calculated by the request schedule management unit 130 in step S1 and the total amount of provided computer resources calculated by the resource allocation schedule management unit 160 in step S2. The surplus resource amount for each is calculated (step S3). Further, the schedule matching unit 170 detects a time point (t1, t2,... Tn) when the surplus resource amount is less than the specified value (step S4).

  Further, the resource allocation schedule management unit 160 detects a cloud service system in which resource shortage is predicted at each time point (t1, t2,... Tn) detected in step S4, as shown in FIG. The required time (si) for allocating the virtualization apparatus to the detected cloud service system is calculated (step S5). The schedule matching unit 170 sets each time point (ti) (i = 1, 2,..., N, the initial value is 1) and the current time point (T) when the surplus resource detected in step S4 is less than the specified value. The difference is compared with the required time (si) required for the allocation of the virtualization apparatus (step S6).

  The schedule matching unit 170 determines that the difference between any time point (ti) when the surplus resource is less than the specified value and the current time point (T) is greater than the required time (si) required for the allocation of the virtualization apparatus. If so (step S7: YES), i is counted up (step S8). Here, the schedule matching unit 170 determines whether or not the value of i is larger than n (step S9). If it is determined that the value of i is greater than n (step S9: YES), the process returns to step S1, and if it is determined that the value of i is not greater than n (step S9: NO), the process returns to step S6. On the other hand, in step S7, the schedule matching unit 170 determines that the difference between any time point (ti) when the surplus resource becomes less than the specified value and the current time point (T) is the required time (si) required for the allocation of the virtualization apparatus ) Is determined to be not greater than (step S7: NO), the resource allocating unit 180 performs virtualization apparatus allocation processing (step S10). The virtual network management device 200 switches network segments based on an instruction from the resource allocation unit 180 of the resource transaction device 100. Here, the processing from step S6 to step S10 can be expressed as, for example, for (i = 1 ;; i <= n) {if (ti−T> si) i ++ else to step S10}.

  In the example of FIG. 9, the virtualization apparatus allocation process performed by the resource transaction apparatus 100 at regular intervals has been described. However, the virtualization apparatus allocation process is performed in response to an allocation request transmitted from the first cloud service system 1000. You may make it perform according to it. FIG. 10 is a sequence diagram illustrating an operation of assigning a virtualization apparatus in response to an assignment request transmitted from the cloud management apparatus 1100.

  The provision request receiving unit 1110 of the cloud management apparatus 1100 can receive a computer resource provision request from the user terminal 500, and the determination unit 1130 can provide a computer resource corresponding to the provision request from the virtualization apparatus allocated to itself. If not, the allocation request unit 1150 transmits a virtual device allocation request to the resource transaction device 100 (step S11). The schedule matching unit 170 of the resource transaction device 100 detects that the virtualization device 2300-1 of the second cloud service system 2000 has a surplus resource of the computer resource corresponding to the provision request. The resource allocation unit 180 transmits an allocation request for allocating the virtualization apparatus 2300-1 detected by the schedule matching unit 170 to the cloud management apparatus 1100 to the virtual network management apparatus 200 (step S12).

  The virtual network management apparatus 200 switches the network segment of the virtualization apparatus 2300-1 to the first cloud service system 1000 in response to the virtualization apparatus allocation request, and allocates the network segment to the cloud management apparatus 1100 (step S13). The virtual network management device 200 transmits a completion notification indicating that the allocation process has been completed to the resource transaction device 100 (step S14). The resource transaction device 100 transmits a completion notification to the cloud management device 1100 (step S15).

  As described above, when any of the cloud service systems connected to the network has a surplus resource for providing computer resources in response to a provision request transmitted from a user terminal, the resource provision system 1 is less than a specified value. In addition, a virtualization apparatus belonging to the machine pool 3000 is allocated to the cloud service system. As a result, each cloud service system connected to the resource providing system 1 is newly virtualized from the machine pool 3000 even when computer resources cannot be provided only by the virtualization devices belonging to the cloud service system. It is possible to provide computer resources to the user terminal by receiving the allocation of the computer.

<Operation example: Resource release>
Next, an operation example in which the resource providing system 1 according to the present embodiment releases the virtualization apparatus from the cloud service system to the machine pool 3000 will be described with reference to FIG. Here, a virtual device release process performed by the resource transaction device 100 at regular intervals will be described. The resource transaction apparatus 100 performs a release process of the virtualization apparatus allocated to the cloud service system in which a surplus of computer resources occurs according to the status of the cloud service system connected to the network.

  The request schedule management unit 130 reads the provision request for each cloud service system stored in the request schedule storage unit 120, and calculates a predicted value of the provision amount for each fixed time according to the provision request as shown in FIG. (Step S21). The cloud state management unit 140 reads the provided amount of the computer resource that each cloud service system provides to the user terminal at the present time (T) from the cloud management device of each connected cloud service system, as shown in FIG. Such usage status information is calculated and stored (step S22).

  The resource allocation schedule management unit 160 uses the cloud service as shown in FIG. 6 based on the provision request amount stored in the request schedule storage unit 120 and the difference between the provision amount and the provision amount of each cloud service system. Calculate the predicted amount of provision for each system. The schedule matching unit 170 calculates the total amount of computer resource provided included in the predicted value of the requested request amount calculated by the request schedule management unit 130 in step S21 and the usage status information calculated by the resource allocation schedule management unit 160 in step S22. Based on the above, the surplus resource amount for every fixed time is calculated (step S23). In addition, the schedule matching unit 170 determines whether or not there is a cloud service system in which a period in which the surplus resource amount is equal to or greater than a predetermined value exists (step S24), and if there exists, detects the period. .

  If the schedule matching unit 170 determines that there is a cloud service system in which a period in which the surplus resource amount is equal to or greater than a predetermined value exists (step S24: YES), the start time of the detected period is before the current time (T). It is determined whether or not there is (step S25). If the schedule matching unit 170 determines that the start time of the detected period is before the current time (T), the resource allocation unit 180 performs a process for releasing the surplus resource (step S26).

  In the example of FIG. 11, the virtualization apparatus release process performed by the resource transaction apparatus 100 at regular intervals has been described. However, the virtualization apparatus release process is performed in response to a release request transmitted from the first cloud service system 1000. You may make it perform according to it. FIG. 12 is a sequence diagram showing an operation in which the resource transaction device 100 releases the virtualization device in response to the release request transmitted from the first cloud service system 1000.

  The release request unit 1160 of the cloud management device 1100 is, for example, a virtualization device whose load is reduced according to the allocation amount and the provision amount stored in the resource amount storage unit 1120 and the provision request received from the user terminal 500 It is detected that the virtualization apparatus 1300-1 can be made free by moving the virtual machine 1300-1 to the virtualization apparatus 1300-2. The cloud management apparatus 1100 transmits a virtual machine migration request to the cluster management apparatus 1200-1 (step S31). The cluster management device 1200-1 moves the virtual machine generated in the virtualization device 1300-1 to the virtualization device 1300-2 (step S33). Here, the movement of the virtual machine is performed by a live migration function in the virtualization technology.

  When the virtualization apparatus 1300-1 completes the movement of the virtual machine to the virtualization apparatus 1300-2, the virtualization apparatus 1300-1 transmits a completion notification to the cluster management apparatus 1200-1 (step S34). The cluster management device 1200-1 transmits a release request for the virtualization device 1300-1 to the resource transaction device 100 (step S35). The resource transaction device 100 transfers the release request to the virtual network management device 200 (step S36). Then, the virtual network management apparatus 200 transfers the IP address assigned to the virtualization apparatus 1300-1 to an IP address corresponding to the network segment in the machine pool 3000, so that the virtualization apparatus 1300-1 is transferred to the first cloud. Release from the service system 1000 (step S37). When the release processing of the virtualization device 1300-1 is completed, the virtual network management device 200 transmits a completion notification to the resource transaction device 100 (step S38). The resource transaction device 100 sends a cleanup request to the cleanup device 3200 for the virtualization device 1300-1 released in step S37. In response to the transmitted cleanup request, the cleanup device 3200 performs a cleanup process of the virtualization device 1300-1 (step S40).

  When the cleanup process of the virtualization apparatus 1300-1 is completed, the cleanup apparatus 3200 transmits a completion notification to the resource transaction apparatus 100 (step S41). The resource transaction apparatus 100 transmits a management request for the virtualization apparatus 1300-1 for which the cleanup process has been performed in step S40, to the machine pool management apparatus 3100 (step S42). When the machine pool management device 3100 stores the virtualization device 1300-1 as a computer device belonging to itself in response to the management request, the machine pool management device 3100 transmits a completion notification to the resource transaction device 100 (step S43). The resource transaction device 100 transmits a completion notification indicating that the physical machine release processing has been completed to the cluster management device 1200-1 (step S44).

<Second Embodiment>
Next, a second embodiment of the present invention will be described. This embodiment is an embodiment when there are a plurality of combinations of the plurality of cloud service systems described in the first embodiment and the resource transaction device 100. That is, in the present embodiment, as shown in FIG. 13, between the resource providing system 1 in the first embodiment installed in the data center 10000 and the similar resource providing system 1 installed in the data center 20000. In this way, computer resources are interchanged.

  Here, for example, the resource allocation unit 10180 of the resource transaction apparatus 10100 in the data center 10000 is requested by the difference between the allocation amount and the provision amount of the computer resources connected to its own network (data center 10000) and the provision request. And whether or not it is possible to provide computer resources according to the provision request from the virtualization device connected to its own network, and determined that the provision is possible In this case, the computer resource is provided to the user terminal 500 that is the transmission source of the provision request. On the other hand, if it is determined that it cannot be provided, a virtual machine allocation request is transmitted to the resource transaction apparatus 20100 of another network (data center 20000), and the resource transaction apparatus 20100 of the data center 20000 is responded to the transmitted allocation request. Are allocated to the cloud management apparatus 11100 that is the request source of the allocation request.

  Here, for example, each computer device in the data center 10000 is connected via a LAN having a high line speed, but the data center 10000 and the data center 20000 are connected via a network 30000 such as the Internet. Here, for example, in a virtual machine of a plurality of virtualization apparatuses 11300 managed by the cluster management apparatus 11200-1, a web (WEB) server (Web Server), an application (AP) server (AP Server), and a database (DB) When a server (DB Server) is constructed, it is desirable that all virtual machines belonging to such a cluster are connected to a LAN having a high line speed. Therefore, the resource allocation unit 10180 of the resource transaction device 10100 performs a computer resource allocation request to the resource transaction device 20100 for each cluster.

  Furthermore, when allocating virtualization apparatuses across data centers, the virtual machine is moved between the data centers using the live migration function, and all the virtualization apparatuses 11300 in the same cluster have the same data. It may be constructed in the center. In this case, the resource allocation unit 10180 of the resource transaction apparatus 10100 requests to provide a new computer resource in the same cluster as the virtual machine provided by the virtualization apparatus 11300-1 in its network (data center 10000). All the virtualization apparatuses belonging to the cluster corresponding to the virtual machine provided by the virtualization apparatus 11300 when it is determined that the computer resource corresponding to the received provision request is not provided from within its own network The resource transaction device 20100 of the data center 20000 is assigned to the resource transaction device 20100, and the operating virtual machine is moved to the virtualization device assigned from the resource transaction device 20100 in response to the transmitted assignment request.

  Here, a plurality of virtual machines belonging to the same cluster are preferably provided by the virtualization apparatus 11300 installed in the same data center. For example, a WEB server, an AP server, and a DB server cooperate with each other. In general, more information is transmitted / received between the AP server and the DB server than information transmitted / received between the WEB server and the AP server. High load. Therefore, even when a plurality of virtual machines belong to the same group, for example, the WEB server and the AP server or the DB server are allowed to be installed in different data centers, and the AP server and the DB server are installed in different data centers. Installation may not be allowed.

  For example, FIGS. 14 to 16 are diagrams illustrating examples of data tables that are referred to when determining whether or not to allow a virtual machine belonging to the same group to be constructed across a plurality of data centers. It is. These data tables are stored in the resource allocation unit 10180 of the resource transaction device 10100. For example, as shown in the group table of FIG. 14, the virtual machine provided to the user terminal 500 is associated with the virtual machine ID, identifies the cluster to which the virtual machine belongs, and starts the virtual machine An OS (Operation System) and an image file such as application software used at the time are stored. In this example, for example, it can be determined that the virtual machines whose virtual machine IDs are “124”, “246”, and “267” belong to the group whose group ID is “26”.

FIG. 15 is a diagram illustrating an example of data in an attribute table that associates an image file with an attribute of the image file. Here, for each image file, an image attribute indicating which one of the WEB server, the AP server, and the DB server is activated is stored.
FIG. 16 is a data example showing a data example of a constraint table indicating that a virtual machine having the image attribute is required to be installed in the same data center for each image attribute. Here, the relationship that is allowed to be installed in different data centers is indicated as “0”, and the relationship that is not allowed to be installed in different data centers is indicated as “1”. The resource allocation unit 10180 of the resource transaction apparatus 10100 makes an allocation request to another data center based on such a rule table.

  Note that the cloud computing service provided in the resource providing system 1 as described above is mainly provided to the unspecified number of people via the Internet. There is an increasing demand for building cloud computing services. That is, there is a demand for a private cloud that builds a cloud computing service environment in a network segment that is isolated from the network segment connected to the Internet and provides a cloud computing service for the company. However, as described above, the cloud computing service has the advantage that the required amount of computer resources is leveled out as the system becomes larger, so when configuring a small private cloud It is difficult to enjoy the benefits of cloud computing. Therefore, the resource transaction apparatus 100 according to the present embodiment may share computer resources between a public cloud that is open to the Internet and a private cloud that is permitted to be used only within a company. As a result, even in a small private cloud, it is possible to enjoy the advantages of cloud computing.

  In addition, in an SI system constructed by an SI (System Integrator) operator or the like, the load may change depending on the time zone or season. In such a case, surplus resources in the SI system may be attributed to the machine pool 3000 by the resource transaction device 100 and made available to other cloud service systems. In this way, computer resources in the SI system can be used effectively.

  Further, the resource transaction apparatus 100 may allow the computer resource in the grid computing system that integrates and uses the computer resources of a plurality of physical machines and the computer resource in the cloud service system to be accommodated. As described above, the resource providing system 1 according to the present embodiment can be applied to various types of housing services that provide services using a plurality of computer devices installed in a base such as a data center.

  In this embodiment, the computer resource capability value per virtual machine is determined in advance, and the computer resource provision request with the unit number per virtual machine is accepted. A machine may be a unit, or a provision request corresponding to any one of the capability values of a plurality of virtual machine levels determined in advance may be accepted.

  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-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, what is called a difference file (difference program) may be sufficient.
