Description

The present invention relates to a virtual infrastructure management device, a virtual infrastructure management method, and a virtual infrastructure management program for managing an environment on a virtual infrastructure.

IT (Information Technology) assets used in an organization, such as personal computers and servers, are loaded with a lot of software, and individual items are set for each. In addition, at software development sites, in order to evaluate manufactured software, multiple evaluation items are repeated by multiple people for multiple environment variations derived from a certain environment, and the same environment is reproduced. There may arise situations where Multiple environment variations include installing or not installing software, turning on or off settings, and so on.

In this case, generally, an environment is constructed on a virtual base and the evaluation is performed. However, since there is a trade-off between convenience, disk capacity, and fault tolerance, the administrator needs to design the environment in consideration of these factors.

For example, consider installing an operating system (hereinafter referred to as OS) on a virtual base, and then installing a plurality of software or registering a plurality of settings based on that point in time. It is assumed that there is an evaluation task in which the environment is repeatedly returned to a plurality of environments registered in this manner. As a general method, there is a method of recording a point in time to be evaluated with a snapshot function. However, the more time points recorded, the shorter the evaluation time, but the more disk space is required.

As another case, consider using not only the snapshot function but also the function to copy the entire disk. In this case, since evaluation can be performed by a plurality of people, operability is improved. For example, even if a failure occurs in one terminal, it does not affect the other terminal, so an improvement in failure tolerance can be expected. However, even in this case, a lot of disk space is required.

In practice, terminal administrators decide how to copy virtual terminals and how to record snapshots, considering multiple performance values such as convenience, disk capacity, operability, and fault tolerance. It is necessary to design and build such as However, in order to do this work, the knowledge of the administrator is required for each environment, and if not properly implemented, extra process costs will be required.

Patent Literature 1 describes a management system that prevents excessive allocation of resources of a shared system used for test execution of multiple software developments. The management system described in Patent Literature 1 appropriately reserves resource allocation in consideration of the type of test for each development project with respect to resource allocation in the virtual base.

Patent Literature 2 describes a resource control device that scales out a virtual server at an appropriate timing. The device described in Patent Literature 2 obtains an appearance frequency count value of a keyword related to a service provided by its own site from another website, and calculates a virtual Scale out your server.

Further, Patent Document 3 describes a remote copy system that performs remote copy operation according to the user's usage status. In the system described in Patent Literature 3, the monitoring server determines the operational purpose of the secondary site based on resource usage information and access frequency trends collected from the main NAS (Network Attached Storage) device and each secondary NAS device. Each NAS device is controlled so as to perform remote copying by a copy method according to the determination result.

In the system described in Patent Literature 1, how to use the allocated resources is entrusted to the user, and it is difficult to say that fault tolerance and convenience can be ensured after allocating the resources. In addition, although the device described in Patent Document 2 can distribute the load for a single service, it does not consider managing the state of resources on the virtual infrastructure in the first place.

In addition, the system described in Patent Document 3 determines the copy method based on information from a hardware perspective, such as NAS device resources and access frequency. However, the system described in Patent Document 3 determines the processing (copy method, etc.) of a machine whose operation is fixed like NAS. Therefore, in the system described in Patent Literature 3, it is difficult to manage an environment including machines on virtual infrastructures whose operations are not fixed (that is, variations in operations are expected).

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example of an embodiment of a virtual infrastructure management device according to the present invention. The virtual infrastructure management device 1 of this embodiment includes a virtual infrastructure 100 . The virtual base 100 is a part in which machine resources such as a CPU (central processing unit) and memory are secured for each information terminal described later, and a part in which an operating system (hereinafter referred to as OS) can be installed. .

The virtual base 100 is implemented using software or the like that implements virtualization. Any method may be used to realize the virtual infrastructure 100, and for example, widely known virtualization software may be used.

The virtual base 100 includes an information terminal 200 , a management terminal 300 and an information terminal control section 400 . In other words, the information terminal 200 , the management terminal 300 and the information terminal controller 400 are built on the virtual base 100 .

The information terminal 200 corresponds to, for example, a personal computer and IT (IT) assets such as a server. In this embodiment, the information terminal 200 is constructed (installed) in the virtual base 100 in the form of software. Therefore, the information terminal 200 itself can be duplicated or deleted in the virtual infrastructure 100 . The information terminal 200 has an information collection unit 201 , an information transmission unit 202 , a snapshot acquisition request unit 203 and a collection information database 204 .

The information collection unit 201 collects operational information of the information terminal 200 . The operation information is various kinds of information that can be obtained from the information terminal 200 that the administrator pays attention to when operating the virtual infrastructure 100. For example, the difference in disk capacity from the past state, and the information required for building the environment of the information terminal 200. time, frequency of use assumed for the evaluation environment, and the like. However, the operational information is not limited to this information, and may be machine resources, installation status of software, and the like.

The information transmission unit 202 transmits the collected operational information to the management terminal 300 .

The snapshot acquisition request unit 203 uses an API (Application Programming Interface) of the information terminal control unit 400 to request the information terminal control unit 400 to acquire a snapshot. The snapshot acquisition request unit 203 requests the information terminal control unit 400 to acquire a snapshot in response to a user instruction, for example, after a patch is applied to the information terminal 200 . Note that the snapshot acquisition request unit 203 may automatically detect a change in the state of the information terminal 200 and request acquisition of a snapshot.

The collected information database 204 has a function as a database and stores various kinds of information collected regarding the information terminal 200 .

In this embodiment, the case where one information terminal 200 is constructed on the virtual base 100 is illustrated, but the number of information terminals 200 is not limited to one, and may be two or more.

The management terminal 300, like the information terminal 200, is a terminal that manages the information terminal 200 and corresponds to IT resources such as personal computers and servers. The management terminal 300 is also constructed (installed) in the virtual base 100 in the form of software. The management terminal 300 has an information reception section 301 , a management information calculation section 302 , a structure management section 303 , a collected information management database 304 and an information terminal structure database 305 .

The information receiving unit 301 receives operational information transmitted from the information transmitting unit 202 and stores it in the collected information management database 304 .

The collected information management database 304 is a database that stores operational information of each information terminal 200 .

The information terminal structure database 305 is a database that stores the structure of the environment transition of the information terminal 200 . Specifically, the information terminal structure database 305 stores the environmental transition represented by a tree structure in which the state in which the snapshot of the information terminal 200 was obtained is set as a node and the transition of the state is set as an edge. Each node is represented by an identifier that can identify its state, for example.

FIG. 2 is an explanatory diagram showing an example of the structure of the environment transition of the information terminal 200. As shown in FIG. The example shown in FIG. 2 shows that environmental transitions generated by snapshots are represented in a tree structure. For example, "OS" illustrated in FIG. A state in which patch A is applied from this state and a snapshot is acquired corresponds to the “patch A” state. Similarly, the state in which patch C is applied and a snapshot is acquired corresponds to the state of "patch C". The same is true for other nodes.

As illustrated in FIG. 2, identification information such as "patch A", "OS", and "SW-A" may be manually given by the user. Further, such information may be stored in the collected information management database 304 as list information collected from the information terminal 200 .

FIG. 3 is a flowchart illustrating an example of processing for saving the state of the environment. First, the person in charge creates an environment that needs to be saved (step S100). Processing for creating an environment includes, for example, software installation, security patch application, and setting change. After that, when the snapshot is obtained (step S101), the information collecting unit 201 obtains necessary operational information (step S102). The information transmission unit 202 transmits the acquired operational information to the management terminal 300 (step S103).

The structure management unit 303 manages the structure of environmental transitions stored in the information terminal structure database 305 according to changes in the environment of the information terminal 200 . Specifically, the structure management unit 303 updates the environment transition structure when there is an increase or decrease in the number of snapshots acquired for the information terminal 200 . The structure management unit 303 may update the environment transition structure, for example, when a new snapshot is acquired or when an existing snapshot is deleted. The increase/decrease in snapshots is notified by the information terminal control unit 400, which will be described later.

The management information calculation unit 302 determines a method for the information terminal control unit 400 to control the environment of the information terminal 200 based on the operation information of the information terminal 200 and the structure of the environment transition. The control of the environment of the information terminal 200 includes control of creating, changing, and deleting the information terminal 200 itself, and control of acquiring, dividing, deleting, and combining snapshots of the information terminal 200 . In the following description, the control of creating, changing, and deleting the information terminal 200 itself is referred to as control of the information terminal 200, and the control of acquiring, dividing, deleting, and combining snapshots is referred to as the snapshot. is described as control.

Specifically, the management information calculation unit 302 may determine which of the information terminal 200 and the snapshot should be preferentially controlled based on the operation information. For example, from the viewpoint of disk capacity, the management information calculation unit 302 may lower the priority of acquiring a snapshot as the change in disk capacity from the previous state increases. Further, the management information calculation unit 302 may, for example, give a higher priority to acquiring a snapshot as the environment construction time is longer, from the viewpoint of the environment construction time. Furthermore, the management information calculation unit 302 may, for example, give a higher priority to acquiring a snapshot as the assumed frequency of use increases.

The management information calculation unit 302 may determine which of the information terminal 200 and the snapshot should be preferentially controlled based on the priority calculated based on these multiple points of view.

Further, the management information calculation unit 302 determines whether environment control is necessary based on whether or not the structure of the operational information or the environmental transition matches a predetermined condition. Predetermined conditions include, for example, whether the remaining disk capacity is less than or equal to a threshold preset by the administrator, and whether or not the complexity of the environment transition structure (tree) is greater than or equal to the threshold.

FIG. 4 is a flow chart showing an example of processing for determining the environment control method (environment recombination) by the management information calculation unit 302 . This process is performed periodically, for example. The management information calculation unit 302 compares a preset threshold with the value of the current environment (step S200), and determines whether or not countermeasures are necessary. If it is determined that no action is required (No in step S201), the process ends.

On the other hand, if it is determined that countermeasures are necessary (Yes in step S201), the management information calculation unit 302 determines an environment control method from the operational information and the structure of the environment transition (step S202). Specifically, the management information calculation unit 302 determines the control to be performed for a certain performance characteristic based on the operational information acquired by the process illustrated in FIG. 3 and the structure of the current environment transition of the information terminal 200. Calculate the index (hereinafter also referred to as score) for Here, the performance characteristic is, for example, the disk capacity, and the control to be performed is, for example, the deletion of the snapshot as exemplified above.

For example, the management information calculation unit 302 calculates a value by multiplying each piece of operational information by a weight, and uses the sum of the values for each type of operational information as the score of the state of the information terminal 200 to determine the structure of the environment transition. It may be calculated for each indicated state (that is, each node). However, the score calculation method is an example, and the score may be calculated by replacing with another calculation method.

The management information calculation unit 302 determines whether or not there is a manageable (controllable) information terminal 200 based on the calculated score (step S203). Is it possible for the management information calculation unit 302 to perform control according to a predetermined criterion (for example, depending on the highest, lowest, or highest index) by, for example, sorting the scores calculated for each node? You can decide whether or not If there is no information terminal 200 that can handle the problem (No in step S203), the process ends.

On the other hand, if there is an information terminal 200 that can be dealt with (Yes in step S203), the management information calculation unit 302 changes the environment structure, such as copying the information terminal 200 and deleting or combining snapshots, based on the determination result. The information terminal control unit 400 is requested to perform recombination processing (step S204). For example, when it is determined that an unnecessary snapshot exists, the management information calculation unit 302 may instruct the information terminal control unit 400 to delete the snapshot. Further, for example, when constructing an environment in which the tree structure illustrated in FIG. A plurality of instructions, such as, may be sent to the information terminal control unit 400 in order.

The process illustrated in FIG. 4 is repeated until there are no information terminals 200 that can be dealt with. By doing so, it becomes possible to optimize the environment (evaluation environment).

The information terminal control unit 400 controls the environment of the information terminal 200 constructed on the virtual base 100 . Specifically, the information terminal control unit 400 controls the environment of the information terminal 200 based on the environment control method determined by the management information calculation unit 302 . The information terminal control section 400 has a function providing interface 401 , an information terminal management section 402 and a snapshot management section 403 .

The function providing interface 401 notifies each function in the information terminal control unit 400 of a processing request from the information terminal 200 . Further, when the structure of the environment transition is changed due to a processing request from the information terminal 200, the function providing interface 401 notifies the structure management unit 303 of the change in the structure of the environment transition. For example, when a snapshot is changed, the function providing interface 401 may notify the structure management unit 303 of the content of the change. Note that the timing of the notification is arbitrary, and the function providing interface 401 may actively notify, or may notify in response to polling from the structure management unit 303 .

Furthermore, the function providing interface 401 notifies each function in the information terminal control unit 400 of the environment control method determined by the management information calculation unit 302 .

The information terminal management unit 402 manages the information terminal 200 . Specifically, the information terminal management unit 402 creates, changes, and deletes the information terminal 200 .

A snapshot management unit 403 manages snapshots of the information terminal 200 . Specifically, the snapshot management unit 403 creates, divides, changes, and deletes snapshots.

The virtual base 100 is implemented by a computer CPU that operates according to a program. More specifically, the information terminal 200 constructed on the virtual base 100, the management terminal 300, and the information terminal control unit 400 are implemented by a CPU of a computer that operates according to a program (virtual base management program). For example, the program is stored in a storage unit (not shown) of the virtual infrastructure management apparatus 1, the CPU reads the program, and operates as the information terminal 200, the management terminal 300, and the information terminal control unit 400 according to the program. You may

More specifically, the information collection unit 201, the information transmission unit 202, the snapshot acquisition request unit 203 in the information terminal 200, the information reception unit 301 in the management terminal 300, the management information calculation unit 302, and the structure management unit 303, the function providing interface 401 in the information terminal control unit 400, the information terminal management unit 402, and the snapshot management unit 403 are also realized by the CPU of the computer that operates according to the program (virtual infrastructure management program).

Also, the collected information database 204, the collected information management database 304, and the information terminal structure database 305 are implemented by, for example, a memory (not shown) provided in the virtual infrastructure management apparatus 1. FIG.

Next, the operation of the virtual infrastructure management device 1 of this embodiment will be described. FIG. 5 is a flow chart showing an operation example of the virtual infrastructure management device 1 of this embodiment. The information collection unit 201 collects operation information of the information terminal 200 (step S11). The structure management unit 303 also manages the structure of the environment transition of the information terminal 200 (step S12). The management information calculation unit 302 determines an environment control method for the information terminal 200 built on the virtual base 100 based on the operational information and the structure of the environment transition (step S13). Then, the information terminal control unit 400 controls the environment of the information terminal 200 on the virtual base 100 based on the determined environment control method (step S14).

As described above, in the present embodiment, the information collection unit 201 collects operational information of the information terminal 200 and the structure management unit 303 manages the structure of the environment transition of the information terminal 200 . Then, the management information calculation unit 302 determines the method of controlling the environment of the information terminal 200 built on the virtual infrastructure 100 based on the operational information and the structure of the environment transition, and the information terminal control unit 400 determines The environment of the information terminal 200 is controlled based on the environment control method. Therefore, the environment on the virtual base can be appropriately managed.

For example, since the administrator of the virtual infrastructure 100 and the person in charge of evaluation using the environment of the virtual infrastructure 100 may be organizationally different, it is often difficult to communicate appropriately. . In such a situation, by introducing the virtual infrastructure management device 1 of the present embodiment, the administrator does not need to check the resources of the virtual infrastructure 100 each time and request the person in charge to take stock of the information terminal 200. become.

Also, by using the virtual infrastructure management device 1 of the present embodiment, it is possible to adjust the environment to the optimum point in time. Therefore, the person in charge only needs to save the information at the time of need, and the complexity of management can be reduced. Therefore, effective use of machine resources (for example, adjustment of disk capacity), which has been difficult to do manually, can be expected.

In addition, it improves fault tolerance so that even if one evaluation system goes down, another important system can be used, and convenience is achieved by making it easier to set up the environment necessary for evaluation by multiple people. It is expected to have effects such as improvement and reduction of convenience due to reduction of human error such as deletion of information at the time of need.

That is, in this embodiment, the information collection unit 201 acquires necessary information from each state of the information terminal 200, and the collected information management database 304 centrally manages the information. The management information calculation unit 302, for example, periodically calculates the environmental situation according to parameters, etc., and based on the result, the information terminal control unit 400 performs recopying or snapshotting of the information terminal 200 at the necessary timing. It automatically manages the division, combination, etc. Therefore, the environment on the virtual base can be appropriately managed.

Next, a modification of the virtual infrastructure management device of this embodiment will be described. In this embodiment, the case where the information terminal control unit 400 manages the information terminal 200 and manages snapshots has been described. The information terminal control unit 400 may also have other functions provided by the virtual base 100 . In this case, the information terminal control section 400 may have processing sections corresponding to respective functions.

Next, an outline of the present invention will be described. FIG. 6 is a block diagram showing an overview of the virtual infrastructure management device according to the present invention. A virtual infrastructure management apparatus 80 (for example, virtual infrastructure management apparatus 1) according to the present invention controls (for example, copies) the environment of an information terminal (for example, information terminal 200) built on a virtual infrastructure (for example, virtual infrastructure 100). an information terminal control unit 81 (for example, the information terminal control unit 400) that acquires snapshots, etc.) and an information collection unit 82 (for example, the information collection unit 201 ), a structure management unit 83 (for example, a structure management unit 303, an information terminal structure database 305) that manages the structure of the environment transition of the information terminal (for example, a tree structure), and based on the operation information and the structure of the environment transition, and a determination unit 84 (for example, the management information calculation unit 302) that determines the environment control method.

The information terminal control unit 81 controls the environment of the information terminal on the virtual base based on the environment control method determined by the determination unit 84 .

With such a configuration, the environment on the virtual base can be appropriately managed.

Further, the determination unit 84 calculates a score for determining the control to be performed from the operational information and the structure of the environment transition, and determines whether the control is performed based on whether the calculated score matches a predetermined condition. You can decide whether it is necessary or not.

Specifically, the determination unit 84 calculates a value by multiplying each piece of operational information by a predetermined weight, and calculates the sum of the above values for each type of operational information as the score of the state of the information terminal. It may be calculated for each state indicated by the structure of the environment transition (for example, for each node of the tree structure), and based on the calculated score, it may be determined whether or not there is a controllable information terminal.

Further, the determination unit 84 may determine which of the information terminal and the snapshot should be preferentially controlled based on the operational information.

Specifically, the determining unit 84 may determine which of the information terminal and the snapshot should be preferentially controlled based on the priority calculated based on a plurality of viewpoints.

With respect to the above-described viewpoints, the determination unit 84 calculates a lower priority for acquiring a snapshot as the disk capacity change is larger, and a higher priority for acquiring a snapshot as the environment construction time is longer. A higher priority for obtaining a snapshot may be calculated as the usage frequency of the snapshot is higher.
