Description

  The present invention relates to a resource allocation device, a resource allocation method, and a program for performing resource allocation in provisioning.

  In recent years, companies and the like have adopted systems that can dynamically allocate resources (computer resources) as business systems. This is for the purpose of efficiently using limited resources and minimizing the resources allocated to each business in a situation where a plurality of businesses are operating.

  In the business system, new resources are also allocated in accordance with the operating status of the system. For example, a new server is allocated from a resource, or a server with high performance is replaced so that the load is concentrated on a server that operates one business and the processing in this server is not in time.

  Conventionally, a technique for performing such resource allocation has been disclosed (see, for example, Patent Document 1). Patent Document 1 discloses a technique for improving the accuracy of computer resource allocation in a Web three-tier system (Web / AP / DB). In the technique disclosed in Patent Document 1, information that identifies a performance difference for each item between resources by combining management information indicating a state related to the performance and capacity of each resource and management information of resources used by a business application. Is acquired in advance. Since resource allocation is performed using this information, it is considered that the allocation accuracy is improved.

JP 2008-59599 A

  By the way, in order to minimize the computer resources allocated to each business, it is necessary to define requirements for each business. For example, assuming an environment in which multiple operations are performed on a Web three-tier system (Web / AP / DB), the number of processes per unit time, that is, transaction processing performance values, etc., is defined as a requirement for each operation Is done. Therefore, resource allocation and reallocation need to be performed so that the defined requirements are satisfied.

  However, with the technique disclosed in Patent Document 1, the business content is not considered in the management information, and it is difficult to allocate resources according to the business content. In addition, if the administrator manually corrects all management information according to the work, it may be possible to allocate resources according to the work contents, but in this case, the burden on the administrator becomes very large. End up.

  On the other hand, as a method of allocating resources according to the business, the performance items that can be collected as the configuration information of each resource such as the CPU (central processing unit) name, the number of clocks, the memory, and the disk capacity are collected for each business There is a method (first method) for setting a required performance value.

  However, since the required performance of business is usually set only by the overall throughput, it is technically difficult to quantitatively determine the performance value required by the performance item for each business in advance. . Moreover, even if it is set, there is a high possibility that it is inaccurate or excessive, and there is a tendency that unexpected performance deterioration occurs in the system or it is biased to overspec.

  In addition, there is a method (second method) in which a performance item of a resource to be emphasized for each business is designated in advance, and then a necessary performance value is set. According to the second method, since the number of items to be specified is smaller than that in the first method, the performance value can be easily set.

  However, in the second method, when there are a large number of performance items to be defined for each business, a large amount of information is required to select the performance item to be emphasized, which makes it difficult to set the performance value. turn into.

  A resource allocation method that solves the problem caused by the second method is known. In this method, the required performance is not determined for each business before allocating resources, but the business is executed on a trial or actual basis, thereby collecting performance values for each server, and from this performance value, it is necessary for the business. Performance items and required performance values are determined. However, with this method, performance values must be collected by executing all types of operations on all servers, and there is a risk that the collection operation itself may become overhead for the operations.

  As described above, when performing resource allocation, it is necessary to consider that the performance items to be emphasized differ for each business, but for each business, the necessary performance values for all performance items are determined and Setting is enormous in the work and is practically difficult to execute.

(Outline of the present invention)
When allocating resources in a business system, it is necessary to consider that performance items that should be emphasized differ depending on the type of business. Even if the performance items of the virtual server are selected without considering the business characteristics, the expected execution efficiency cannot be obtained. Conversely, the work of determining and setting required performance values for all performance items in the virtual server is enormous.

  For this reason, considering the fact that the performance items that should be emphasized for each business are different, a sufficient number of performance items can be used to allocate resources, and there is a method for managing these settings with less effort. Necessary. In order to realize this, the following method is considered in the present invention.

First, the business system administrator (user) selects business characteristics that match the target business. As a result, business and business characteristics are linked. The business characteristics represent items to be emphasized according to the nature of the business. As business characteristics, for example, “calculation performance emphasis (
CPU performance emphasis), “data transfer amount emphasis (I / O capacity emphasis)”, “data transfer performance emphasis (I / O performance emphasis)”, and the like.

  Each business characteristic is further composed of a plurality of performance items to be emphasized, and the configured performance items are weighted by importance. For example, when the business characteristic is “CPU performance emphasis”, the weight of the performance item related to the CPU processing is set large, and the weight of the performance item related to the disk access speed is set small.

  Next, performance values are collected from each virtual server for each performance item. In all the virtual servers, performance (inherent performance) values that do not vary depending on the contents of the business can be collected from the configuration information of each virtual server. On the other hand, in the virtual server, values of performance (variation performance) that vary depending on the contents of the business, such as disk I / O performance, bandwidth that can be used by the NIC (Network Interface Card), etc., are stored in the virtual server. Acquired by executing a job.

  Further, instead of causing the virtual server to execute an actual job, a pseudo job corresponding to the actual job may be executed. Note that the execution of the pseudo work refers to causing the virtual server to input and set artificially set data. Furthermore, actual performance is executed on a specific virtual server and performance values are collected. From the obtained performance values, a ratio of performance values indicating the relationship between actual business and pseudo-business is obtained, and this ratio is used. It is also possible to obtain the performance value of another virtual server that is not executing actual business.

  In the present invention, the business performance of the entire business, such as the value of the transaction processing performance, is a value of the intrinsic performance estimated from the performance items determined by the values of the fluctuation performance collected in the situation where the actual business is operating and the business characteristics. Calculated using the value. In this case, the weights assigned to the performance items related to the business characteristics are considered.

  Next, resources are allocated using the calculated business performance. Specifically, a virtual server that exceeds the calculated business performance and has a minimum performance value is selected. The virtual server can be selected using a generally known FFD (First-Fit Decreasing) algorithm or the like.

  As described above, according to the present invention, an appropriate resource corresponding to a business is allocated only by the administrator setting a minimum parameter (by simply selecting one of the business characteristics). Note that the process for allocating resources after the calculation of business performance can be performed according to a normal provisioning mechanism.

(Embodiment)
Next, a resource allocation device, a resource allocation method, and a program according to an embodiment of the present invention will be described with reference to FIGS. Initially, the structure of the resource allocation apparatus in this Embodiment is demonstrated using FIGS. 1-4. FIG. 1 is a block diagram showing a configuration of a resource allocation device according to an embodiment of the present invention.

  As shown in FIG. 1, a resource allocation device 1 according to the present embodiment is a device that allocates resources in a business system 100 that executes a plurality of business operations using two or more virtual servers. In the present embodiment, the business system 100 constructs and operates a plurality of virtual servers A, B, and C by a software technique on a physical computer. In the present embodiment, the virtual servers A, B, and C are constructed using general virtualization software, and the number of virtual servers is not limited.

As shown in FIG. 1, the resource allocation device 1 includes a selection receiving unit 10, a performance item management unit 30, and a business performance calculation unit 60. Among these, the selection reception part 10 receives the selection instruction | indication of the business characteristic of each of several business. In the present embodiment, the selection instruction is input to the selection receiving unit 10 by an administrator of the business system 100 from the outside via an input device such as a keyboard or from the administrator's computer via a network.

  Further, the performance item management unit 30 manages the performance of the virtual server required for executing the corresponding business by dividing it into a plurality of items for each business characteristic. Further, the business performance calculation unit 60 targets at least one of a plurality of business, and selects the business characteristics selected for the target business, each item of the performance of the virtual server corresponding thereto, and the performance of each virtual server. get. Based on these, the business performance calculation unit 60 calculates business performance indicating the degree to which each virtual server is adapted to the target business.

  As described above, in this embodiment, the administrator only needs to select a business characteristic, and thereby the business performance of each virtual server for the target business is calculated. Since the business performance indicates the degree to which each virtual server is adapted to the target business, by using the business performance, it is possible to allocate an appropriate resource corresponding to each business. That is, if the resource allocation device 1 is used, allocation of resources corresponding to each business can be executed without increasing the burden on the administrator.

  Here, the resource allocation device 1 according to the present embodiment will be described more specifically with reference to FIGS. FIG. 2 is a diagram illustrating an example of business characteristics selected for each business in the embodiment of the present invention. FIG. 3 is a diagram showing an example of performance items managed in the embodiment of the present invention. FIG. 4 is a diagram showing the performance of each virtual server used in the embodiment of the present invention.

  As shown in FIG. 1, in the present embodiment, the resource allocation device 1 includes a business property storage unit 20, a performance storage unit 40, in addition to the selection receiving unit 10, the performance item management unit 30, and the business performance calculation unit 60. The variable performance acquisition unit 50, the required performance calculation unit 70, and the resource allocation unit 80 are provided.

  In the present embodiment, the selection receiving unit 10 can provide an interface through a GUI or the like between the resource allocation device 1 and an administrator who performs a selection instruction. In this case, the administrator only has to select one of the business characteristics for each business on the selection screen displayed on the screen of the computer or resource allocation device 1 to be used.

  In the present embodiment, the business characteristics that can be selected through the selection receiving unit 10 are, for example, “calculation performance emphasis (CPU performance emphasis)” and “data transfer amount emphasis (I / O capacity emphasis)”. “Data transfer performance emphasis (I / O performance emphasis)”. Then, the selection receiving unit 10 outputs the information specifying the selected business characteristic to the business characteristic storage unit 20 in a state linked to the business corresponding to the selected business characteristic. As a result, as shown in FIG. 2, each business executed in the business system 100 is stored in the business property storage unit 20 in a state where the business property is linked.

  In the example of FIG. 2, CPU performance emphasis is selected for “Business 1”, I / O capacity emphasis is selected for “Business 2”, and I / O performance emphasis is selected for “Business 3”. Has been. In addition, the business property storage unit 20 is a so-called database in the present embodiment, and can output necessary information in response to a request from another unit. Further, the business property storage unit 20 can store definition parameters for business other than the business properties.

In the present embodiment, the performance item management unit 30, as shown in FIG. 3, for each business characteristic of each business, each item name of the required virtual server specifications (performance) and the weight set for each item, Manage. Specifically, the performance item management unit 30 is a device such as a database that manages the performance item name “CPU clock”, “memory amount”, and the like and the related metrics set for each item in association with each other. is there.

  In the example of FIG. 3, weights normalized so that the total is 1 are added as related metrics for the required performance items for each business characteristic. As shown in FIG. 3, when the business characteristics place importance on CPU performance, for example, the CPU clock weight is set to 0.8 and the memory amount weight is set to 0.2. Further, when the business characteristic is focused on the I / O capacity, for example, the weight of the memory amount is set to 0.5 and the weight of the disk amount is set to 0.5. Further, when the business characteristic is focused on I / O performance, the weight of the disk amount is set to 0.2, and the weight of the disk I / O is set to 0.8. The performance item name and the related metric are created and registered in advance before the resource allocation device 1 operates for the first time.

  Further, in the present embodiment, “virtual server performance” includes “variable performance” that varies depending on the content of the business, and “inherent performance” that does not vary depending on the content of the business. Specifically, the “variable performance” includes a bandwidth that can be used by a network interface card (NIC) provided in the virtual server, an I / O performance of the virtual server disk, and the like. The “inherent performance” includes CPU clock, memory capacity, storage capacity of the disk storage device, and the like in the virtual server.

  The fluctuation performance and the inherent performance are stored in the performance storage unit 40. Specifically, the performance storage unit 40 is a database, and stores variable performance and intrinsic performance values for each virtual server, as shown in FIG. In the example of FIG. 4, the performance storage unit 40 stores each performance value for each of the server A, the server B, and the server C. The example of FIG. 4 shows a case where the server A is executing the business 1. The business performance of server A for business 1 is 50.

  In the present embodiment, the variable performance is acquired by the variable performance acquisition unit 60. The variable performance acquisition unit 60 acquires the variable performance by causing the virtual server A, B, or C to actually execute the business. The variable performance acquisition unit 60 can also acquire the variable performance by causing the virtual server A, B, or C to execute a pseudo business corresponding to the business.

  Here, “to execute a pseudo work” means to input and process artificially set data in the virtual server as described above. Further, the variable performance unit 60 collects performance values by executing actual business on a specific virtual server, and calculates a performance value ratio indicating the relationship between the actual business and the pseudo business from the obtained performance values. It is also possible to obtain the performance value of another virtual server that is not executing the actual business by using this ratio.

  In the present embodiment, the business performance calculation unit 60 acquires the performance of the virtual server from the performance storage unit 60. In the present embodiment, the business performance calculation unit 60 can calculate the business performance with reference to the virtual server currently assigned to the target business. A specific calculation process in the business performance calculation unit 60 will be described later with reference to FIG.

  The required performance calculation unit 70 calculates the performance required for each business in consideration of the business characteristics of each business stored in the business property storage unit 20 and the business performance calculated by the business performance calculation unit 60. . Then, the required performance calculation unit 70 sends information specifying the calculated performance to the resource allocation unit 80. Based on the performance for each business calculated by the required performance calculation unit 70, the resource allocation unit 80 determines a virtual server to be allocated from the resources held by the business system 100 so as to ensure the performance required for each business. And execute resource allocation.

  Next, the operation of the resource assignment device 1 in the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing the operation of the resource allocation device in the embodiment of the present invention. Moreover, the resource allocation method in this Embodiment is implemented by operating the resource allocation apparatus 1 in this Embodiment. For this reason, the description of the resource allocation method in the present embodiment is replaced with the following description of the operation of the resource allocation device 1. In the following, FIGS. 1 to 4 are referred to as appropriate.

  As shown in FIG. 5, first, the selection accepting unit 10 accepts an instruction for selecting the business characteristics of each business (step S1), and the accepted business characteristics (see FIG. 2) are associated with the corresponding business. The stored state is stored in the business property storage unit 20 (step S2).

  Next, the business performance calculation unit 60 obtains the variable performance and inherent performance of each virtual server stored therein from the performance storage unit 40 (step S3). In step S <b> 3, the business performance calculation unit 60 further acquires the business characteristics of each business stored in step S <b> 2 and the performance items for each business characteristic managed by the performance item management unit 30. In the present embodiment, acquisition of variable performance by the variable performance acquisition unit 50 is performed in advance before execution of step S3.

  Next, the business performance calculation unit 60 uses the information acquired in step S3, and the business performance calculation unit 60 uses the virtual server currently assigned to the target business as a reference for the business performance of each virtual server. Is calculated (step S4).

  Here, in the present embodiment, it is assumed that the business 1 is currently operated by the virtual server A as shown in FIG. The business performance calculation unit 60 calculates the business performance of each virtual server based on the virtual server A. Specific business performance calculation processing by the business performance calculation unit 60 is as follows.

  First, the business performance calculation unit 60 calculates the ratio between the performance value of the virtual server A and the performance values of the other virtual servers B and C. Estimate performance. As shown in FIG. 4, the business performance in the business 1 of the virtual server A is 50.

  For example, as shown in FIG. 1, the business 1 is set to emphasize CPU performance, and as shown in FIG. 2, in the related metrics emphasizing CPU performance, the CPU clock is set to 0.8 and the memory amount is set to 0.2. Is set. When comparing the virtual server A and the virtual server B, the CPU clock of the virtual server B is three times that of the virtual server A and the memory amount is 1/4.

  Therefore, the business performance estimated for the virtual server B is 50 × (3 ^ 0.8 × 0.25 ^ 0.2) ≈91.25 taking a weighted geometric average. Similarly, in the virtual server C, the CPU clock is 4 times and the memory amount is 8 times that of the virtual server A. Therefore, the business performance estimated for the virtual server C is 50 × (4 ^ 0.8 × 8 ^ 0.2) ≈229.7

  The business performance of each virtual server obtained in this way is sent to the required performance calculation unit 70. In step S4, since the business performance in the case where the business 1 is executed on each virtual server can be inferred, by using the obtained business performance, when further processing performance is required in the business 1, You can easily determine which computer should be assigned.

Next, the required performance calculation unit 70 calculates the performance necessary for each business while considering the business characteristics stored in step S2 and the business performance calculated in step S4 (step S5). Thereafter, the resource allocation unit 80 uses the virtual server to be allocated from the resources held by the business system 100 so that the performance required for each business is ensured based on the performance for each business calculated by the required performance calculation unit 70. And resource allocation is executed (step S6).

  Moreover, the program in this Embodiment should just be a program which makes a computer perform step S1-S6 shown in FIG. By installing and executing this program on a computer, the resource allocation device 1 and the resource allocation method in the present embodiment can be realized. In this case, the CPU of the computer functions as the selection receiving unit 10, the variable performance acquisition unit 50, the business performance calculation unit 60, the required performance calculation unit 70, and the resource unit 80, and performs processing. Further, the business property storage unit 20, the performance item management unit 30, and the performance storage unit 40 can be realized by storing data files constituting them in a storage device such as a hard disk provided in the computer.

  As described above, according to the present embodiment, the burden on the administrator when performing settings for dynamically allocating resources of the business system 100 is reduced. The reason is that the administrator can select and allocate resources suitable for the business simply by selecting the business characteristics corresponding to the business.

  Further, according to the present embodiment, it is possible to handle performance items according to each business characteristic without increasing the burden of collecting performance items by the administrator. This is because the performance items to be collected in a specific business are determined based on the business characteristics specified by the administrator, and only the target performance items need be collected.

  Furthermore, according to the present embodiment, it is possible to realize resource allocation without causing each virtual server to perform useless processing. This is because the business performance is calculated in consideration of the weight of the performance value according to the business characteristics. That is, the performance value corresponding to the actual business can be calculated for each virtual server even if a large overhead operation such as causing each virtual server to execute each business is not performed.

  As described above, the present invention is effective for a business system that executes a plurality of business operations using two or more virtual servers. The present invention has industrial applicability.
