Description

[0001] In-Memory Based Virtualization Service Providing System [

The present invention relates to a virtualization service providing system, and more particularly, to a virtualization service providing system, in which a virtualization service can be provided by allocating memory instead of allocating storage corresponding to a disk to client terminals connected to a virtualization server, It is possible to provide a high-quality virtualization service by improving the speed, and even when a failure occurs in the virtualization server connected to the client terminal or when the client terminal requests the change of the virtualization server, The present invention relates to an in-memory-based virtualization service providing system capable of continuously providing a virtualization service provided by a virtualization server accessed by another virtualization server at a first time, thereby further improving the quality of the virtualization service.

In recent years, virtualization services have become increasingly important for security of internal trade secrets and customer information in corporations and research institutes, and they have consumed a lot of time and manpower to manage distributed PCs, resulting in efficient use and management through a centralized computer environment. It is a field of technology in which research has been concentrated in recent years because of the growing need.

The virtualization service providing system generally includes a plurality of client terminals, a CB (Connection Broker) manager for authenticating a connection of the client terminals and allowing the client terminals to access the virtualization server, and a virtualization service And a virtualization server that provides the virtualization server.

In a virtualization server, dozens of client terminals can be connected. When dozens of clients connect to the virtualization server through virtualization, resources of the virtualization server are allocated to each client terminal. For example, when the plurality of client terminals access the virtualization server, a storage corresponding to a disk, which is a resource of the virtualization server, is allocated to each client terminal and used.

However, when dozens of client terminals access the virtualization server at the same time, the load of the storage corresponding to the disk concentrates, thereby deteriorating the performance of the entire system. In particular, the disk is significantly slower than the other resources of the virtualization server, i.e., memory, resulting in a greater performance degradation.

On the other hand, the quality of communication status is very important for the continuity of work or work, and it is very necessary to maintain the service until normal connection is blocked.

Various technologies have been proposed to improve the quality of virtualization services. For example, Korean Patent Registration No. 10-1674619 proposes a virtualization service providing system having a monitoring and controlling function of a client terminal capable of improving virtualization quality.

However, the prior art document discloses a method for monitoring the network connection history of the client terminal, allowing resources to be shared as needed, and allowing the allocated resources to be reallocated to improve the quality of the virtualization service. Such as the speed of the storage system.

Korean Patent No. 10-1674619 (Publication Date: Nov. 09, 2016, entitled: Virtualization Service Providing System Having Surveillance and Control Function of Client Terminal)

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above problems occurring in the prior art, and it is an object of the present invention to provide a virtualization service, in which memory is allocated to client terminals connected to a virtualization server, Memory-based virtualization service providing system that enables high-quality virtualization services to be provided by removing loads concentrated on storage and improving speed.

The present invention also provides a virtualization server in which a separate virtualization server having a memory separately from the storage is initially connected to the virtualization server even when a failure occurs in the virtualization server connected to the client terminal or when the client terminal requests a change of the virtualization server Based virtualization service providing system capable of continuously providing a virtualization service based on the virtualization service provided by the virtualization server, thereby further improving the quality of the virtualization service.

According to another aspect of the present invention, there is provided a virtual memory service providing system for authenticating connection between client terminals and client terminals, and allowing the client terminals to access a virtualization server A connection broker (CB) manager, and a virtualization server for providing a virtualization service to the connected client terminals, wherein the virtualization server has a memory separate from the storage, and for each of the connected client terminals, And a control engine for allocating and managing each block, wherein each of the connected client terminals is provided with a virtualization service using the allocated blocks of the memory.

Here, the virtualization server monitors the use state of the memory block allocated to the client terminal. If the virtualization server determines that the use state is the monitoring result, the use is stopped, or the usage degree is less than a predetermined reference value, And a memory monitoring and backup control module for controlling the data stored in the storage to be backed up to the storage.

When a virtualization server change request of the client terminal connected to the virtualization server occurs or a failure occurs in the virtualization server, the client terminal is newly connected according to the control of the CB manager, and the virtualization server The second virtualization server may be a separate virtualization server that is newly allocated and determined to be usable by the CB manager, or may be a redundant virtualization server previously provided to the virtualization server And the second virtualization server has a memory allocated to the client terminal separately from the storage.

If there is a virtualization server change request of the client terminal connected to the virtualization server, the CB manager may migrate data related to the client terminal backed up in the storage of the virtualization server to the storage of the second virtualization server, Wherein the second virtualization server controls the migration of data related to the client terminal stored in a block of memory of the virtualization server to a block of memory of the second virtualization server and, when the second virtualization server is redundantly reconfigured with the virtualization server, The virtualization server allocates to the client terminal a block of memory in which data related to the client terminal is stored at the same time that the client terminal is connected to the second virtualization server.

In addition, when a failure occurs in the virtualization server, the CB manager causes data related to the client terminal backed up in the storage of the virtualization server to be migrated to the storage of the second virtualization server, The second virtualization server allocates to the client terminal a block of memory in which data related to the client terminal is stored at the same time that the client terminal is connected to the second virtualization server.

If the memory of the virtualization server and the memory of the second virtualization server are synchronized in real time in a case where the second virtualization server is redundantly connected to the virtualization server, Is allocated in real time from the memory of the virtualization server to the client terminal, and if the memory of the virtualization server and the memory of the second virtualization server are not in real time synchronization The second virtualization server extracts data related to the client terminal from the storage of the second virtualization server that receives the data related to the client terminal from the storage of the virtualization server in real time and stores the data, Save to block A block of the memory is allocated to the client terminal.

According to the in-memory virtualization service providing system of the present invention having the above technical problems and the solution, instead of assigning storage corresponding to a disk to client terminals connected to a virtualization server, a virtualization service is provided , It has the advantage of providing high-quality virtualization services by eliminating the burden on storage and speeding up the storage.

According to the present invention, even when a failure occurs in a virtualization server connected to a client terminal or when a client terminal requests a change of a virtualization server, the virtualization server, which is initially connected to another virtualization server having a memory separately from the storage, The virtualization service can be continuously provided. Therefore, the quality of the virtualization service can be further improved.

3 is a block diagram for explaining redundancy and migration, which further includes a second virtualization server in an in-memory virtualization service providing system according to an embodiment of the present invention.

Hereinafter, preferred embodiments of an in-memory virtualization service providing system according to the present invention having the above-described problems, solutions and effects will be described in detail with reference to the accompanying drawings.

The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator.

First, a virtualization service applied to the present invention refers to a service capable of establishing a virtual PC environment on the Internet and realizing a business environment anytime and anywhere without restriction of time and space through various terminals.

In addition, the in-memory technology applied to the present invention refers to a technique of storing data in a RAM, not a disk. Because the processing speed is up to 10,000 times faster than the disk storage method, it is developed as a data storage, processing and analysis solution centering on database (DB) specialized companies such as SAP and Oracle. In addition to SSDs that use flash memory, DRAMs that do not store data are also used as in-memory DB materials due to technological development.

1 is a configuration diagram of an in-memory virtualization service providing system according to an embodiment of the present invention.

1, an in-memory-based virtualization service providing system 100 according to an embodiment of the present invention basically comprises a plurality of client terminals 10, a plurality of client terminals 10, A CB (Conting Broker) manager 20 for allowing the terminals 10 to access the virtualization server 30 and a virtualization server 30 for providing the virtualization service through the virtual machine to the connected client terminals 10, As shown in FIG.

The client terminals 10 may be any terminal capable of accessing the Internet, such as a desktop, a PC such as a notebook computer, a smart device such as a smart phone, and a tablet PC. The client terminals 10 access the virtualization server 30 allocated by the CB manager 20 in order to receive the virtualization service.

Common client terminals 10 utilize the resources of the connected virtualization server 30, that is, the storage corresponding to the disk. Specifically, each of the client terminals 10 in the existing virtualization service providing system can receive the virtualization service using the disk allocated by the connected virtualization server 30.

However, each of the client terminals 10 according to the present invention can be provided with a virtualization service using a specific area (block) of memory allocated by the connected virtualization server 30. [ That is, in the present invention, each of the client terminals 10 connected to the virtualization server can receive the virtualization service using the block of the allocated memory. This will be described in more detail later.

When the performance of the virtualization server 30 is deteriorated, for example, when it is determined that the speed is slow, the client terminal 10 can request to be replaced with another virtualization server by the user, Furthermore, when a fault occurs in the virtualization server 30, a new virtualization server, that is, a second virtualization server 30 'can be newly automatically accessed according to the control of the CB manager 20 to receive a continuous virtualization service.

The CB manager 20 according to the present invention allocates the virtualization server 30 to the client terminal 10 at the request of the user and provides a function of managing creation, management, disappearance and migration of the virtual machine.

Specifically, the CB manager 20 assigns the virtualization server 30 to the client terminals 10 at the request of the user. That is, the CB manager 20 authenticates the connection of the client terminal 10 to the virtualization server, and allows the client terminal to access the virtualization server.

More specifically, the CB manager 20 grasps the operation status of the authentication module 21 and the virtualization server 30, which allow connection between the client terminal 10 and the virtualization server 30 through client authentication, A server allocation module 23 for allocating a virtualization server 30 to a terminal and a monitoring module 25 for monitoring an operation state of the virtualization server 30.

The authentication module 21 confirms the access right of the user through the login authentication of the user who wants to connect to the virtualization server 30 so that only the authorized user can access the virtualization server 30, It allows the allocation of arbitrary virtual machines. The authentication module 21 also plays a role of setting an environment according to the user account information so that the user can access the virtual machine again at a desired time when the use of the virtual machine allocated to the user is terminated.

The server allocation module 23 monitors the real-time operating state of the virtualization server 30 through the monitoring module 25 and allocates an optimal virtualization server to the client terminal.

The monitoring module 25 monitors in real time the resource allocation status of the virtualization servers, the usage information and the use of the generated virtual machines, and allocates the optimal virtualization server to the client terminal by referring to the server allocation module do.

The monitoring module 25 checks whether the virtualization server 30 has a failure or the client terminal 10 requests replacement with another virtualization server. If a failure occurs or a virtualization server is replaced If there is a request, the client terminal 10 controls access to a new virtualization server, that is, a second virtualization server 30 ', and at the same time, when data migration is required, the first virtualization server 30, (30 '). This will be described later.

When the client terminal 10 is connected to the virtualization server 30 according to the authentication of the CB manager 20, the general virtualization server 30 transmits the virtualization service through the virtual machine to the connected client terminal 10 Lt; / RTI > Specifically, the virtualization server 30 controls a virtual machine through a hypervisor, designates a virtual machine for executing a virtualization service for the client terminal, and allocates resources allocated to the client terminal 10 To be executed in the virtual machine.

The virtualization server 30 according to the present invention has a storage 31 corresponding to a disk. In the present invention, unlike a general virtualization service providing system, the storage 31 is not allocated to the connected client terminals 10 and is not used. The storage 31 is not allocated to each client terminal in the present invention because there is a problem of speed inherent in the disk and the speed related to reading and writing data is very slow compared with memory. Instead, the present invention is provided with a memory 33 corresponding to the RAM so as to be allocated to each of the client terminals 10 connected thereto.

As described above, according to the present invention, the virtualization server 30 includes the memory 33 separately from the storage 31. [ The memory 33 is allocated to the connected client terminals 10 by area, that is, on a block-by-block basis by the control engine 35. Specifically, the virtualization server 30 includes a memory 33 separately from the storage 31, and a control engine 32 for allocating and managing each block of the memory 33 to each of the client terminals 10 connected thereto. (35).

The control engine 35 allocates a specific area of the memory 33, that is, a specific block, to each of the client terminals 10 connected to the virtualization server 30. Therefore, each of the client terminals 10 connected to the virtualization server 30 can receive the virtualization service using the allocated block of the memory 33 itself.

Since each of the client terminals 10 connected to the virtualization server 30 can receive a predetermined virtualization service by using the block of the memory 33 instead of the storage 31, And the speed of data processing such as specific task processing can be increased, thereby providing a high-quality virtualization service.

The memory 33 may be divided into a plurality of blocks B1 to Bn as shown in FIG. 2 and the control engine 35 may be divided into a plurality of blocks B1 to Bn, And allocates and manages the blocks of the memory 33 to each of the client terminals 10. [

The control engine 35 allocates and manages blocks of the memory 33 to each of the client terminals 10 to be connected to the control engine 35. In this case, Blocks can also be allocated. In FIG. 2, the client terminal 5 and the client terminal 6 both share a block B5 of the memory and share the same.

Specifically, when the client terminal 5 is using a specific operating program or a specific execution program in the memory block B5 and the client terminal 6 intends to use the same specific operating program or specific execution program, the control engine 35 Assigns the block B5 of the memory 33 used by the client terminal 5 to the client terminal 6 so that the specific operating program or the specific execution program can be used together.

As described above, the control engine 35 can manage the client terminals 10 using the same program to share and use blocks of the same memory 33, so that the use efficiency of the memory 33 Can be improved.

When the control engine 35 recognizes that the different client terminals 10 are allocated to different blocks of the memory 33 and use the same specific program, The block allocation of the memory 33 is reallocated and allocated so that the two client terminals 10 can use the same block of the memory 33. [ As a result, the use efficiency of the memory 33 can be further improved through such duplication removal.

As described above, each of the client terminals 10 is provided with a virtualization service using blocks of the allocated memory 33. In this process, virtualization services are provided to the blocks of the memory 33 that are allocated and used The data generated during the process of storing the data is stored.

Since the memory 33 is volatile, if power is turned off or an error occurs, the data is erased. Therefore, it is preferable that the data stored in the block of the memory 33 allocated and used by the connected client terminal 10 is backed up and stored in the storage 31. The virtualization server 30 to which the client terminal 10 is connected monitors the memory and controls the data stored in the block of the memory to be backed up to the storage 31 at a proper time, (37).

That is, the virtualization server 30 monitors the use state of the block of memory 33 allocated to the client terminal 10, and if the result of the monitoring is that the use is stopped or the use degree is less than or equal to a preset reference value And a memory monitoring and backup control module 37 for controlling the data stored in the allocated memory 33 block to be backed up to the storage 31 when judged.

The memory 33 allocated to the client terminal 10 is continuously used in the process of providing the virtualization service. Therefore, the memory monitoring and backup control module 37 controls the data stored in the memory 33 to be backed up to the storage 31 within a range not imposing a load on the block. Therefore, the memory monitoring and backup control module 37 monitors the blocks of the memory 33 and controls the backup process to proceed only when the memory monitoring and backup control module 37 is not used.

Specifically, the memory monitoring and backup control module 37 monitors the use state of the allocated memory block. That is, it monitors whether the block of the allocated memory 33 is in an unused state, specifically, in a disabled state. In this way, if the block of the allocated memory 33 is not used, the memory monitoring and backup control module 37 can back up the allocated virtual memory without affecting the quality of virtualization service provisioning, And controls the data stored in the block of the memory 33 to be backed up to the storage.

On the other hand, in the case where the allocated memory block is not in a suspended state and is used for a certain amount of time, if the used memory block is not frequently used, the virtual memory service quality is greatly influenced . Therefore, if it is determined that the use level of the block of the allocated memory is equal to or less than a preset reference value, the memory monitoring and backup control module 37 determines that the allocated memory 33 to be backed up to the storage.

In this manner, the data stored in the memory 33 allocated to the client terminal 10 can be backed up to the storage 31. Therefore, even if the data stored in the allocated memory 33 is deleted due to various reasons, the client terminal 10 can use the data related to the virtualization service provided by itself, through recovery, duplication, or migration process, Furthermore, virtualization services can be provided continuously.

According to the in-memory virtualization service providing system 100 of the present invention configured as described above, instead of assigning the storage 31 corresponding to the disk to the client terminals 10 connected to the virtualization server 30, 33 are allocated to receive the virtualization service. Thus, there is an advantage in that it is possible to provide a high-quality virtualization service by eliminating the load concentrated on the storage 31 and improving the speed.

However, when there is a problem with the virtualization server 30 connected to the client terminal 10 and the client terminal 10 can not receive the virtualization service, or when the virtualization service is provided in a state where the quality is deteriorated It is possible. That is, when the failure occurs in the virtualization server 30, the client terminal 10 can not continuously receive the virtualization service currently being performed, and when the performance of the virtualization server 30 drops for various reasons, for example, When the data processing speed is slow, there is a problem that the virtualization service of good quality is not continuously provided.

If the client using the client terminal 10 determines that the performance of the virtualization server 30 is degraded, the client can request the virtualization server 30 to change to another virtualization server. Then, the CB manager 20 allocates a new virtualization server, that is, a second virtualization server 30 ', so that the client terminal 10 can newly connect.

On the other hand, when the failure occurs in the virtualization server 30 connected to the client terminal 10, that is, when the operation is abnormal or incapable of operation, the CB manager 20 notifies the new virtualization server 30 That is, the second virtualization server 30 ', so that the client terminal 10 can newly connect.

3, the in-memory-based virtualization service providing system 100 according to the present invention further includes the second virtualization server 30 ', and when a failure occurs in the virtualization server 30, When the virtualization server change request of the client terminal 10 connected to the virtualization server 30 is issued, the client terminal 10 connected to the virtualization server can be continuously provided with the virtualization service.

As described above, the in-memory-based virtualization service providing system 100 according to the embodiment of the present invention may be configured such that when there is a virtualization server change request of the client terminal 10 connected to the virtualization server 30 or when the virtualization server 30 A second virtualization server (hereinafter, referred to as " virtual server ") that allows the client terminal 10 to be newly connected and receive a virtualization service provided by the virtualization server 30 according to the control of the CB manager 20 30 ').

Here, the second virtualization server 30 'may be a separate virtualization server 30' newly determined to be available by the CB manager 20, or may be configured to be duplicated with the virtualization server 30 in advance Is a separate virtualization server 30 'and the second virtualization server 30' has a memory 33 'allocated to the client terminal 10 separately from the storage 31'.

Specifically, the client terminal 10 can request a virtualization server change request to the virtualization server 30, and the virtualization server 30 notifies the CB manager 20 of a virtualization server change of the client terminal 10 Communicate the request. Then, the CB manager 20 allocates the second virtualization server 30 'to the client terminal 10 so that the second virtualization server 30' can be connected.

The monitoring module 25 of the CB manager 20 can monitor other virtualization servers in real time. Accordingly, the monitoring module 25 extracts another virtualization server, that is, another available virtualization server having a small usage and a high speed, and transmits the extracted virtualization server to the server allocation module 23. Then, the server allocation module 23 allocates the virtualization server determined to be available as the second virtualization server 30 'to the client terminal 10 so as to be connected.

As described above, the second virtualization server 30 'may be a newly allocated virtualization server determined by the CB manager 20 to be available, but in order to enhance continuous virtualization service provision, Or may be a separate virtualization server configured to be redundant with the virtualization server 30. That is, the second virtualization server 30 'may be a virtualization server previously configured for redundancy.

If the failure occurs in the virtualization server 30 regardless of the virtualization server change request of the client terminal 10, the monitoring module 25 of the CB manager 20 notifies the failure of the virtualization server 30 And directly allocates the second virtualization server 30 'so that the client terminal 10 can be connected. Also in this case, the CB manager 20 allocates the second virtualization server 30 'so that the client terminal 10 is connected to the client terminal 10 as if the client terminal 10 had a virtualization server change request The second virtualization server 30 'may be a separate virtualization server for redundancy configured in advance, or may be a newly allocated virtualization server that is determined to be available by the CB manager 20 have.

The second virtualization server 30 'may be a general virtualization server. However, as shown in FIG. 3, the second virtualization server 30' includes a storage 31 'as much as the virtualization server 30 according to the present invention. And a memory 33 'that can be allocated to the newly connected client terminal 10 separately from the storage 31'.

As a result, the second virtualization server 30 'may allow the virtualization server 30 to continuously provide the virtualization service provided to the client terminal 10 through the memory 33' . That is, the client terminal 10 newly connected to the second virtualization server 30 'uses the blocks of the memory 33' allocated by the second virtualization server 30 ' .

In order for the client terminal 10 to continuously receive the virtualization service provided from the virtualization server 30 through the second virtualization server 30 ', data stored in the virtualization server 30 It must be delivered. That is, the second virtualization server 30 'receives data related to the client terminal 10 from the virtualization server 30 through the migration or is redundantly and non-redundantly with the virtualization server 30, (10). This will be described in detail as follows.

First, a virtualization server change request of the client terminal 10 connected to the virtualization server 30 will be described.

In this case, the CB manager 20 controls the data related to the client terminal 10 (the client terminal making the virtualization server change request) from the virtualization server 30 to the second virtualization server 30 ' do.

More specifically, the CB manager 20 transmits data related to the client terminal 10 backed up to the storage 31 of the virtualization server 30 to the storage 31 'of the second virtualization server 30' To be migrated. The data stored in the block of the memory 33 allocated to the client terminal 10 is backed up in the storage 31 according to the control of the memory monitoring and backup control module 37 as described above, Data relating to the client terminal 10 may be migrated from the storage 31 of the virtualization server 30 to the storage 31 'of the second virtualization server 30'.

In addition to the migration of the storage data, the migration of the memory data may be possible. That is, if the migration from the memory 33 of the virtualization server 30 to the memory 33 'of the second virtualization server 30' is made possible, no failure occurs in the virtualization server 30 May be migrated from the block of the memory 33 of the virtualization server 30 to the block of the memory 33 'of the second virtualization server 30'. That is, the CB manager 20 determines that the data related to the client terminal 10 stored in the block of the memory 33 of the virtualization server 30 is stored in the memory 33 'of the second virtualization server 30' Block to be migrated.

The CB manager 20 may be configured to migrate data related to the client terminal 10 from the storage 31 of the virtualization server 30 to the storage 31 'of the second virtualization server 30' Migrated from the memory 33 of the virtualization server 30 to the memory 33 'of the second virtualization server 30' may be operated or all of the operations may be performed.

However, if the CB manager 20 controls only the migration of data related to the client terminal backed up to the storage of the virtualization server to the storage of the second virtualization server, the second virtualization server 30 'transmits data related to the client terminal 10 stored in the storage 31' to the block of the memory 33 '.

Specifically, the second virtualization server 30 'is a block of the memory 33' allocated to the client terminal 10 by data related to the client terminal 10 stored in the storage 31 ' To be transmitted and stored. Then, the client terminal 10 may receive the virtualization service continuously provided through the virtualization server 30 using the block of the memory 33 'allocated by the second virtualization server 30' .

Meanwhile, as described above, if the CB manager 20 is controlled to perform an operation of migrating from the memory 33 of the virtualization server 30 to the memory 33 'of the second virtualization server 30' , Since data related to the client terminal 10 is already stored in the memory 33 'of the second virtualization server 30', data from the storage 31 'of the second virtualization server 30' Are not received separately. However, the second virtualization server 30 'may be configured such that the data (data related to the client terminal) migrated from the memory 33 of the virtualization server 30 is stored in the memory 33' allocated to the client terminal 10 Block.

It is possible to continuously provide the virtualization service to the client terminal 10 without such a migration operation. To this end, the second virtualization server 30 'is configured to be non-redundantly redundant with the virtualization server 30 as described above.

In this case, that is, when the second virtualization server 30 'is redundantly and non-redundantly with the virtualization server 30, the second virtualization server 30' The client terminal 10 is connected to the client terminal 30 'and a block of the memory 33' in which data related to the client terminal 10 is stored is allocated to the client terminal.

Specifically, when the second virtualization server 30 'and the virtualization server 30 are redundantly interrupted, the data related to the client terminal 10 generated in the virtualization server 30 is transmitted to the second virtualization server 30' Is transmitted to the server 30 'and is synchronized. That is, the data related to the client terminal 10, in which the virtualization server 30 is backed up and stored in the storage 31, can be transmitted and stored in the second virtualization server 30 'in real time, If the memory 33 of the virtualization server 30 and the memory 33 'of the second virtualization server 30' are configured to be synchronized with each other, the memory 33 of the virtualization server 30, The data related to the second virtualization server 10 may be transferred to and stored in a specific memory 33 'block of the second virtualization server 30'.

In this case, the virtualization server 30 and the second virtualization server 30 'may be redundantly configured. In this case, the storage 31 of the virtualization server 30 and the second virtualization server 30' Only the memory 31 'of the virtualization server 30 and the memory 33' of the second virtualization server 30 'may be configured in synchronization with each other, , Both of which may be configured in synchronization with each other.

If only the storage 31 of the virtualization server 30 and the storage 31 of the second virtualization server 30 'are configured in synchronization with each other, the second virtualization server 30' The data related to the client terminal 10, which is stored in synchronization with the client terminal 10 in real time, can be transmitted to and stored in a specific block of the memory 33 '.

Accordingly, if the virtualization server 30 and the second virtualization server 30 'are configured in a non-redundant manner, the data related to the client terminal 10 generated in the virtualization server 30 can be real- May be stored in a specific memory 33 'block of the virtualization server 30'.

If the second virtualization server 30 'and the virtualization server 30 are configured in a non-redundant manner, if there is a virtualization server change request of the client terminal 10 connected to the virtualization server 30 The client terminal 10 can access the second virtualization server 30 'under the control of the CB manager 20 and the second virtualization server 30' Allocates a specific memory 33 'block in which data related to the client terminal is already stored. Then, the client terminal 10 can continuously receive the virtualization service using the allocated memory 33 'block of the second virtualization server 30'.

If there is a virtualization server change request of the client terminal 10 connected to the virtualization server 30 as described above, the CB manager 20 transmits the virtualization server change request to the virtualization server 30, The data related to the terminal 10 is migrated to the storage 31 'of the second virtualization server 30' or the client terminal 10 stored in the block of the memory 33 of the virtualization server 30, Is migrated to a block of the memory 33 'of the second virtualization server 30', and when the second virtualization server 30 'is redundantly non-redundantly with the virtualization server 30 , The second virtualization server 30 'is connected to the second virtualization server 30' and the block of the memory 33 'storing the data related to the client terminal 10 is connected to the second virtualization server 30' The client terminal 10 It is plane. Then, the client terminal 10 can receive the virtualization service provided through the virtualization server 30 continuously.

In the case where the second virtualization server 30 'is redundantly and non-redundantly connected to the virtualization server 30 as described above, the memory 33 of the virtualization server 30 and the second virtualization server 30' The second virtualization server 30 'receives data related to the client terminal 10 from the memory 33 of the virtualization server 30 in real time if the memory 33' of the virtualization server 30 is synchronized in real time And allocates a block of the memory 33 'of the second virtualization server 30' to the client terminal 10 so that the memory 33 of the virtualization server 30 and the second virtualization server 30 The second virtualization server 30 'receives data related to the client terminal 10 from the storage 31 of the virtualization server 30 in real time if the memory 33' of the virtualization server 30 is not synchronized in real time From the storage 31 'of the second virtualization server 30' The block of the memory 33 'can be allocated to the client terminal 10 after the data related to the client terminal is extracted and stored in the block of the memory 33' of the second virtualization server 30 ' have.

Hereinafter, a case where there is a virtualization server change request of the client terminal 10 connected to the virtualization server 30 has been described. Next, a case where a failure occurs in the virtualization server will be described.

Even in this case, the CB manager 20 can not migrate data related to the client terminal 10 (client terminal connected to the failed virtualization server) from the virtualization server 30 to the second virtualization server 30 ' Respectively.

Specifically, the CB manager 20 transmits data related to the client terminal 10 backed up to the storage 31 of the virtualization server 30 until the failure occurs in the storage of the second virtualization server 30 ' (31 '). The data stored in the block of the memory 33 allocated to the client terminal 10 is backed up in the storage 31 according to the control of the memory monitoring and backup control module 37 as described above, Data relating to the client terminal 10 may be migrated from the storage 31 of the virtualization server 30 to the storage 31 'of the second virtualization server 30'.

Meanwhile, when a failure occurs in the virtualization server 30, the power is generally turned off. Therefore, when a failure occurs, data in the memory 33 of the virtualization server 30 is transferred. Therefore, in this case, the migration from the memory 33 of the virtualization server 30 to the memory 33 'of the second virtualization server 30' is not considered.

The CB manager 20 moves the data related to the client terminal 10 from the storage 31 of the virtualization server 30 to the storage 31 'of the second virtualization server 30' .

When the CB manager 20 proceeds to migrate data related to the client terminal backed up to the storage of the virtualization server to the storage of the second virtualization server, the second virtualization server 30 ' 'To the block of the memory 33'.

Specifically, the second virtualization server 30 'is a block of the memory 33' allocated to the client terminal 10 by data related to the client terminal 10 stored in the storage 31 ' To be transmitted and stored. Then, the client terminal 10 may receive the virtualization service continuously provided through the virtualization server 30 using the block of the memory 33 'allocated by the second virtualization server 30' .

Meanwhile, even when a failure occurs in the virtualization server 30, the virtualization service can be continuously provided to the client terminal 10 without the migration operation. To this end, the second virtualization server 30 'is configured to be non-redundantly redundant with the virtualization server 30 as described above.

The description of this case is omitted because the contents described in the case where there is a virtualization server change request of the client terminal connected to the virtualization server can be directly applied.

According to the present invention described above, even when a failure occurs in the virtualization server 30 connected to the client terminal 10 or when the client terminal 10 requests a change of the virtualization server, the storage 31 ' Since the virtualization server 30 is configured to continuously provide the virtualization service provided by the virtualization server 30 initially accessed by another virtualization server (the second virtualization server 30 ') having the virtualization server 33' So that the quality can be further improved.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
