Description

  The present invention relates to a virtual computer system, a management server, a virtual machine construction method, and a program therefor, and more particularly, to a virtual computer system, a management server, and a virtual machine that can be quickly recovered using a virtual computer system. The present invention relates to a method and a program thereof.

  In the present day when computer networks have already become an important social infrastructure, data loss and information system outages due to large-scale disasters such as earthquakes, fires, storms and floods are serious social losses. Therefore, it is important to quickly restore the information system when such a large-scale disaster occurs. Such recovery of information systems from a large-scale disaster is called disaster recovery.

  Computer virtualization technology is considered to play an important role in disaster recovery. If a backup site that backs up data in the data center is built at a location physically separated from the data center where the virtual computer is operated, this backup site will have the same virtual site if the data center goes down due to a disaster. You can build a computer and take over the work smoothly. As a result, it is considered that disaster recovery can be realized in which processing for recovery can be performed easily, quickly, and at low cost.

  There are the following documents as technical documents related to this. Patent Document 1 describes a virtual machine system that enables reallocation of physical resources to virtual machines. Patent Document 2 describes a virtual computer system in which different logical computers are assigned to different physical processors in a computer having a plurality of physical processors in order to improve reliability against hardware failure.

  In Patent Document 3, in order to configure a logical computer that can be moved among a plurality of real computers, a virtual processor that finds a physical processor that can be allocated from a processor allocation amount for each logical computer and allocates the logical computer to the physical processor is found. A computer system is described. Non-Patent Document 1 describes a disaster recovery verification experiment using computer virtualization technology.

(First embodiment)
Hereinafter, the structure of the 1st Embodiment of this invention is demonstrated based on attached FIGS. 1-2.
First, the basic content of the present embodiment will be described, and then more specific content will be described.
The virtual computer system 1 according to the present embodiment has the same function as the virtual machine 32 that backs up data in the data center 10 that constructs a virtual machine 32 that is a virtual computer accessible from the user terminal 31. This is a virtual computer system having a backup center 20 capable of constructing a virtual machine 32a. The data center 10 receives business definition information from a user terminal and determines a virtual machine configuration according to the business definition information, and a physical server that operates the virtual machine based on the management server determined configuration. It has a plurality of physical machines 111 to 11n which are computer devices. The management server 100 stores the physical machine information 161, which is information related to the current processing capability of the physical machine, and the business definition analysis unit 151 that analyzes the business definition information 170 received from the user terminal. And an arrangement pattern generation unit 152 for generating a plurality of arrangement patterns, which are arrangements of virtual machines on the physical machine, from the physical machine information and the job definition information, and the processing time required for constructing the virtual machine for each arrangement pattern. Processing time evaluation means 153 for selecting and calculating an arrangement pattern that can construct a virtual machine earliest, and virtual machine control for causing a physical machine to construct a virtual machine according to the selected arrangement pattern when the physical machine starts the virtual machine Means 154.

  Here, the task definition information 170 is a task configuration information 171 that defines the applications to be started in each virtual machine and the order in which they are started, and an operation that defines a performance value that represents the processing capability required for each virtual machine. It includes request information 172 and construction request information 173 that defines the amount of processing to be performed by each virtual machine. The arrangement pattern generation means generates an arrangement pattern that satisfies the conditions specified by the operation request information 172 and the construction request information 173 based on the physical machine information 161.

  Then, the processing time evaluation unit 153 determines whether or not there is a virtual machine that performs simultaneous construction processing on the same physical machine at each stage of starting each application with the business configuration information. The processing time is calculated by subtracting the processing capacity of the machine. In addition, the processing time evaluation unit 153 determines whether or not there is a virtual machine that performs the construction process in parallel at each stage of starting each application with the business configuration information, and if it exists, at the same stage. The processing time is calculated by excluding other than the maximum value of the construction processing time of No.

By providing the above configuration, the virtual computer system 1 can quickly perform the reconstruction process related to disaster recovery.
Hereinafter, this will be described in more detail.

  FIG. 2 is an explanatory diagram showing the overall configuration of the virtual computer system 1 according to the embodiment of the present invention. In this embodiment, a user terminal 31 operated by a user connects to the data center 10 via the Internet 30 and operates a virtual machine 32 constructed by the data center 10. At that time, the user terminal 31 transmits job definition information 170 indicating the user's job configuration procedure to the data center 10, and the virtual machine 32, which is a virtual computer, operates according to the job definition information.

  Then, the data in the data center 10 is backed up, and a backup center 20 having the same configuration as the data center 10 is constructed at a location physically separated from the data center 10. When the data center 10 becomes unusable due to a large-scale disaster, the backup center 20 constructs a virtual machine 32a having the same function as the virtual machine 32 and restores the function of the virtual machine 32. Can do.

  FIG. 1 is an explanatory diagram showing an internal configuration of the data center 10 shown in FIG. The data center 10 includes a management server 100 that manages the entire data center 10, and m physical machines 111 to 11 m that are physical computer devices in which virtual machines described later are constructed by management of the management server 100. The network 130 is connected to each other. N virtual machines 121 to 12n are constructed on the physical machines 111 to 11m. Any one of the virtual machines 121 to 12n is the virtual machine 32 illustrated in FIG.

  Here, m and n are both integers, and m = n or m ≠ n. Further, the number of virtual machines constructed for each physical machine may be different. The user terminal 31 is connected to the management server 100 via the Internet 30 and operates the virtual machine 32 that is any one of the virtual machines 121 to 12n.

  The business definition information 170 transmitted by the user terminal 31 is a virtual machine that takes into account the business configuration information 171 that is information about the construction order of the virtual machines 121 to 12n and the processing to be performed at the time of construction, and the peak processing time of business applications. Operation request information 172 that is performance information necessary for stable operation of 121 to 12n, and construction request information 173 that is information about the processing amount necessary to construct a business application on the virtual machines 121 to 12n. It is configured. The configuration of each piece of information will be described later.

  The management server 100 is a computer device that includes a processor 101 that is an arithmetic device that executes a computer program, and a storage device 102 that stores programs and data. In the processor 101, each means such as a business definition analysis unit 151, an arrangement pattern generation unit 152, a processing time evaluation unit 153, and a virtual machine control unit 154 described later operates as a computer program.

  The storage device 102 stores data such as physical machine information 161 and business information 162. The physical machine information 161 is information about the performance of each of the physical machines 111 to 11m. The business information 162 is information on how the virtual machines 121 to 12n are arranged on the physical machines 111 to 11m. The configuration of these pieces of information will also be described later.

  The business definition analyzing unit 151 receives the business definition information 170 from the user terminal 31, analyzes the business definition information, and outputs business configuration information 171, operation request information 172, and construction request information 173. The arrangement pattern generation unit 152 receives the output of the job configuration information 171 and the operation request information 172 from the job definition analysis unit 151, and generates virtual machine arrangement pattern information from these and the physical machine information 161.

  The processing time evaluation unit 153 calculates the construction processing time when the virtual machines 121 to 12n are constructed with the respective virtual machine arrangement patterns from the virtual machine arrangement pattern information generated by the arrangement pattern generation unit 152. A virtual machine arrangement pattern that minimizes the construction processing time is selected. The virtual machine control unit 154 constructs the virtual machines 121 to 12n in accordance with the virtual machine arrangement pattern in which the task start time selected by the processing time evaluation unit 153 is the shortest.

  FIG. 3 is an explanatory diagram showing a more detailed configuration of the backup center 20 shown in FIG. The backup center 20 includes a management server 200 that manages the entire backup center 20, and m physical machines 211 to 21 m that are physical computer devices in which virtual machines described later are constructed by management of the management server 200. The network 230 is connected to each other. Then, n virtual machines 221 to 22n are constructed on the physical machines 211 to 21m.

  As described above, the backup center 20 has the same configuration as that of the data center 10 in principle, so that reference numerals of the respective components are indicated by +100. In addition, a known method can be appropriately used for creating backup data and restoring data therefrom.

  The management server 200 of the backup center 20 does not receive the job definition information 170 directly from the user terminal 31, but duplicates the data in the data center 10 by backup processing and is based on the physical configuration of the backup center 20. Then, processing similar to that of the management server 100 is performed to generate virtual machine arrangement pattern information.

  Accordingly, in the processor 201, the business definition analysis unit 251, the arrangement pattern generation unit 252, and the virtual machine control unit 254 of the processing time evaluation unit 253 perform the same operation as the management server 100 as a computer program.

  FIG. 4 is an explanatory diagram showing an example of the task definition information 170 (task configuration information 171, operation request information 172, and construction request information 173) transmitted from the user terminal 31 shown in FIG. 1 to the task definition analyzing unit 151. . The business configuration information 171 describes the applications to be started in each virtual machine and the order of starting them. Hereinafter, this is referred to as a business construction flow.

  In the example shown in the business configuration information 171 of FIG. 4, as a construction flow for starting a business related to a web service, the database server A is first started (hereinafter referred to as phase 1), and then the web application servers B1 and B2 are started. (Hereinafter referred to as phase 2), and after both of them are activated, the load balancer C is activated (hereinafter referred to as phase 3). Each of these servers must be started and run separately.

  At the same time, since it is essential to be activated according to this construction flow, the activation order cannot be changed. Accordingly, the web application servers B1 and B2 can only be activated after the database server A is activated, and the load balancer C cannot be activated unless both the web application servers B1 and B2 are activated.

  The operation request information 172 includes a virtual machine name 172a of each virtual machine 121 to 12n to be constructed, and a performance value 172b representing the performance required for the virtual machine. The construction request information 173 includes the virtual machine name 172a and the processing amount 173a performed by the virtual machine. The virtual machine name 172a is common data for the operation request information 172 and the construction request information 173.

  In the example shown in the operation request information 172 and the construction request information 173 in FIG. 4, the database server A, the web application servers B1 and B2, and the load balancer C to be constructed with the above-described business configuration information 171 are shown as the virtual machine name 172a. In the operation request information 172, for these virtual machine names 172a, for example, the database server A has a CPU processing capacity of 1000 MHz, a memory capacity of 1000 MB, and a disk I / O of 30 MB / sec for a stable operation. What is needed is at least shown as performance values 172b, 172c, 172d.

  On the other hand, in the construction request information 173, for these virtual machine names 172a, the database server A reads a file of 100MB, the web application server B1 is 10MB, the B2 is 30MB, and the load balancer C reads a 20MB file on each virtual machine. The amount of work 173a indicates that it is necessary to work.

  Here, information for ensuring that virtual machines that should not be stopped at the same time are arranged on different physical servers can be included in the operation request information 172. This makes it possible to create a resource arrangement pattern that considers not only the processing speed at the time of construction but also high availability.

  FIG. 5 is an explanatory diagram showing an example of the storage contents of the physical machine information 161 and the business information 162 shown in FIG. The physical machine information 161 includes a physical machine name 161a of each of the physical machines 111 to 11m connected to the internal network 130, a CPU capability 161b representing the current performance of each physical machine, a memory capacity 161c, and a disk I / O 161d. , And information such as processing capacity 161e. The business information 162 includes information on the business name 162a and the arrangement pattern 162b of the virtual machines 121 to 12n corresponding to the business name.

  In the example shown in FIG. 5, the physical machine information 161 includes three physical machines whose physical machine names 161a are vmm1, vmm2, and vmm3. From the CPU capability 161b, the memory capacity 161c, and the disk I / O 161d, respectively. The derived processing capacity 161e of each physical machine is 110, 100, 120 (all units are msec / MB). The business information 162 will be described later.

  FIG. 6 is a flowchart showing an operation in which the management server 100 shown in FIG. 1 creates the arrangement pattern 162b from the work definition information 170. First, the user terminal 31 transmits the business definition information 170 input by the user and stored on the user terminal 31 to the management server 100 (step S301). The job definition analyzing unit 151 receives and analyzes the job definition information 170 (step S302), extracts the job configuration information 171, the operation request information 172, and the construction request information 173 included in the job definition information 170, and arranges them. It outputs to the pattern generation means 152 (step S303).

  The arrangement pattern generation unit 152 is designated by the job configuration information 171 and the operation request information 172 from the job configuration information 171 and the operation request information 172 output from the job definition analysis unit 151, and the processing capability 161 e of the physical machine information 161. All virtual machine arrangement pattern candidates 180 that satisfy the conditions are created and temporarily stored in the storage device 102 (step S304). The arrangement pattern candidate 180 selected through the processing of FIG. 7 described later is stored in the business information 162 as the arrangement pattern 162b.

  In step S304, the virtual machine arrangement that satisfies the condition that each virtual machine name 172a having the performance value 172b indicated in the operation request information 172 can be constructed on each physical machine indicated in the physical machine information 161 The pattern candidates 180 are determined by brute force. In the example shown in FIG. 5, two of the virtual machine arrangement pattern candidates 180 thus determined are illustrated as resource patterns P1 and P2. Hereinafter, in order to simplify the description, only two examples of resource patterns P1 and P2 will be described.

  In the example shown in FIG. 5, the business name 162a is “Web service” for each virtual machine of the database server A, the web application servers B1 and B2, and the load balancer C indicated by the operation request information 172. Resource patterns P1 and P2 are shown as pattern candidates 180. vmm1 to vmm3 are physical machine names 161a shown in the physical machine information 161. Among them, the resource pattern P2 is stored in the business information 162 as the arrangement pattern 162b.

  In the resource pattern P1, the database server A is assigned to vmm1, the web application servers B1 and B2 are assigned to vmm2, and the load balancer C is assigned to vm3. On the other hand, in the resource pattern P2, the database server A is assigned to vmm1, the web application server B2 and the load balancer C are assigned to vmm2, and the web application server B1 is assigned to vmm3.

  Incidentally, a virtual machine X related to another business not related to the business name “web service” is assigned to vmm1 and is operating. Similarly, a virtual machine Y related to another business is assigned to vmm3 and is operating. These virtual machines X and Y have no particular problem even if they are not described in detail in describing the operation of the present embodiment.

  FIG. 7 is a flowchart showing an operation in which the management server 100 shown in FIG. 1 creates and saves an arrangement pattern 162b adopted from the virtual machine arrangement pattern candidates 180. First, the processing time evaluation unit 153 reads the arrangement pattern candidate 180 temporarily stored in the storage device 102 (step S401). Next, the processing time evaluation unit 153 calculates the processing capacity of each physical machine from the performance value of each physical machine described in the physical machine information 161, here the processing capacity 161e (step S402).

  Subsequently, the processing time evaluation unit 153 calculates the processing amount necessary to construct each business application from the processing amount 173a of the construction request information 173 (step S403). Then, the construction time of the business application on each virtual machine is calculated as an evaluation value from the processing amount calculated here and the processing capacity 161e of each physical machine (step S404). The evaluation value is applied to all the arrangement pattern candidates 180, the time required for the construction process of the entire business is calculated for each arrangement pattern (step S405), and the arrangement pattern having the shortest time is selected. This is stored in the business information 162 as the arrangement pattern 162b (step S406).

  FIG. 8 is a flowchart showing in more detail the processing for calculating the processing capability of each physical machine by the processing time evaluation means 153 shown as step S403 in FIG. The processing time evaluation unit 153 determines whether or not there is a virtual machine that simultaneously performs the construction process on the same physical machine based on the processing flowchart of each business described in the business configuration information 171 (step S501). .

  If not, the processing amount 173a of the construction request information 173 is used as it is for calculating the processing amount in steps S404 to S405 (step S502). If it exists, the amount that the processing capability is reduced due to the simultaneous processing is subtracted from the processing capability 161e and used (step S503). More specifically, it is possible to use a method such as multiplying the processing capacity 161e by the number of virtual machines that are simultaneously configured on the same physical machine and using the value as the apparent processing capacity 161e.

  FIG. 9 is a flowchart showing in more detail the process for calculating the time required for the construction process for the entire business by the processing time evaluation unit 153 shown as step S405 in FIG. The processing time evaluation unit 153 determines whether or not there is a virtual machine that performs the building process in parallel at the same processing stage (phase) related to the building process based on the process flowchart of each job described in the job configuration information 171. Is determined (step S601).

  If it does not exist, the time for each stage of the construction process is added as it is, and the time for the construction process for the entire business is calculated (step S602). If it exists, it is excluded from the objects to be summed other than the maximum value of the construction processing time in the same processing stage, and the rest is summed to calculate the time required for construction processing of the entire business (step S603).

  The example which performed the process shown by the flowchart of said 6-9 about the resource patterns P1 and P2 shown by FIGS. 4-5 is shown. As described above, in the business configuration information 171, as a construction flow for starting a business related to a web service, the database server A is first started (phase 1), and then the web application servers B 1 and B 2 are started in parallel ( The startup sequence of starting the load balancer C after the startup of both of them (phase 2) (phase 3) is shown.

  In the resource pattern P1, virtual machines such as database server A are assigned to physical machine vmm1, web application servers B1 and B2 are assigned to vmm2, and load balancer C is assigned to vmm3. On the other hand, in the resource pattern P2, the database server A is assigned to vmm1, the web application server B2 and the load balancer C are assigned to vmm2, and the web application server B1 is assigned to vmm3.

  First, the processing time evaluation unit 153 reads the resource patterns P1 and P2 in step S401. Subsequently, the processing time evaluation unit 153 reads the processing capacity of each physical machine and the processing amount necessary for building each application in steps S402 to S403. From here, the processing time evaluation means 153 calculates the time required for the construction processing of the entire business in steps S404 to S405.

  As described above, there are three physical machines whose physical machine names 161a are vmm1, vmm2, and vmm3, and their processing capacities 161e are 110, 100, and 120 (all units are msec / MB). Therefore, for example, in the resource pattern P1, the database server A is assigned to the physical machine vmm1 having a processing capacity of 110 msec / MB in phase 1, and the database server A reads the 100 MB file as indicated in the construction request information 173. Since it is necessary to work, the time required for starting this database server A is 100 MB × 110 msec / MB = 11000 msec.

  Similarly, web application servers B1 and B2 are allocated to the physical machine vmm2 in phase 2. This corresponds to the case where step S501 in FIG. 8 is YES. These web application servers B1 and B2 are started simultaneously on the physical machine vmm2, and cannot proceed to phase 3 unless both are started. For this reason, the processing capacity of vmm2 is apparently regarded as half of that, and the numerical value of the processing capacity 161e is doubled to 200 msec / MB. Accordingly, the time required for starting the web application servers B1 and B2 is (10 + 30) MB × 200 msec / MB = 8000 sec.

  In the subsequent phase 3, a load balancer C capable of 120 msec / MB is allocated to the physical machine vmm3, and this load balancer C needs to read and work with a 20 MB file. Therefore, it is necessary to start this load balancer C. The time is 20 MB × 120 msec / MB = 2400 sec. As described above, the time required for starting this web service with the resource pattern P1 is obtained for each of the phases 1 to 3 in step S404, and the total of these is obtained as 11000 + 8000 + 2400 = 21400 msec in step S405.

  On the other hand, the resource pattern P2 is the same as the resource pattern P1 in that the database server A is assigned to the physical machine vmm1 in phase 1, so that the time required for starting the database server A is the same as the resource pattern P1. 100 MB × 110 msec / MB = 11000 msec.

  In the subsequent phase 2, the web application server B2 is assigned to the physical machine vmm2, and the web application server B1 is assigned to the physical machine vmm3. Since both are different physical machines, the processing capability of vmm2 is 100 msec / MB, and the processing capability of vmm3 is 120 msec / MB, as they are, for starting up the web application servers B1 and B2.

  The time required for starting the web application server B1 is 10 MB × 120 msec / MB = 1200 msec, and the time required for starting the B2 is 30 MB × 100 msec / MB = 3000 msec. This corresponds to the case where step S601 in FIG. 9 is YES. Accordingly, only the startup time of 3000 msec of the web application server B2, which takes more time to start the web application servers B1 and B2, is set as the time required for the phase 2.

  In the subsequent phase 3, the load balancer C is assigned to the physical machine vmm2 capable of 100 msec / MB, and this load balancer C needs to read and work with a 20 MB file. Therefore, it is necessary to start the load balancer C. The time is 20 MB × 100 msec / MB = 2000 msec. As described above, the time required to start this web service with the resource pattern P2 is obtained for each of the phases 1 to 3 in step S404, and these are summed in step S405 to obtain 11000 + 3000 + 2000 = 16000 msec.

  As described above, the time required to start this web service with the resource pattern P1 is 21400 msec, and with the resource pattern P2 is 16000 msec. Accordingly, in step S406, the resource pattern P2 having a shorter time is adopted and stored in the business information 162 as the arrangement pattern 162b.

  The examples described above are merely simple examples in order to express the concept of the present invention in an easy-to-understand manner. Actually, not only two resource patterns P1 and P2, but also many arrangement patterns are created as virtual machine arrangement pattern candidates 180 and temporarily stored. Among them, only the one that can start each virtual machine necessary for the task first is stored in the task information 162 as the arrangement pattern 162b.

  FIG. 10 is a flowchart illustrating a process in which the virtual machine control unit 154 (or 254) illustrated in FIG. 1 generates the virtual machines 121 to 12n from the stored arrangement pattern 162b. The virtual machine control means 154 reads the arrangement pattern 162b selected and stored in step S406 of FIG. 8 from the business information 162 of the storage device 102 (step S701), and based on this, the virtual machine 121 is placed on the physical machines 111 to 11m. To 12n are generated (step S702).

  The job definition information 170 is executed by the job definition analysis unit 251 up to step S303 in FIG. 6 on the management server 200 of the backup center 20 by the backup process. When the data center 10 goes down due to a large-scale disaster, virtual machine placement pattern candidates in the backup center 20 are created in S304 of FIG. 7 and the same processing as in FIGS. Using the physical machine information 261 and the business information 262 on the management server 200 of the center 20, the arrangement pattern generation unit 252, the processing time evaluation unit 253, and the virtual machine control unit 254 perform the virtual machines 221 to 22n. This makes it possible to perform disaster recovery quickly at the backup center.
