The present invention relates to a virtual environment control device and a virtual machine management method, and more particularly, to a virtual environment control device and a virtual machine management method for connecting a plurality of computing devices to a virtual machine.

With the rapid growth of the mobile communication industry related to mobile communication devices including smart phones, there is an increasing interest in technologies for using cloud services through mobile terminals. A cloud service is a service that stores various contents on a server connected to the Internet and reads stored contents through various kinds of terminals without restriction of a place.

On the other hand, as the amount of data used for cloud services has increased exponentially, there has been a limit in terms of hardware performance and processing capacity in order to process the whole data only by a personal computer. For this reason, in order to process a large amount of data and efficiently share computing resources, virtual machines of a virtualization environment configured by combining a plurality of computing devices are used. Such a computing method is called cloud computing.

Software-defined networking (SDN) is a networking approach to support cloud computing. The SDN is a networking method that separates the control plane and the data plane and transfers the data by determining the packet delivery method for each of the distributed SDN switches. The SDN defines an API (Application Programming Interface) between the data plane and the control plane. In the defined API, free network configuration is possible independently.

The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the invention may be practiced. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with one embodiment.

It should also be understood that the position or arrangement of the individual components within each disclosed embodiment can be variously modified without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is principally defined by the appended claims, encompassed by the appended claims and their equivalents. Where similar reference numerals are used in the figures, like reference numerals refer to the same or similar functions for various embodiments.

Hereinafter, the contents and ideas of the present invention will be described with reference to the accompanying drawings.

As a typical method for improving the performance of a software implemented function or a function implemented in a virtual machine using a general server, there are a scale-up method and a scale-out method.

The scale-up method is a method of improving the processing capability of the virtual server or the virtual machine itself. For example, a method of replacing a processor used in a virtual server with a high-performance processor or assigning additional computing resources to a virtual machine within the range of available computing resources corresponds to a scale-up method. However, there are some limitations such as having a high-performance processor, or allocating additional computing resources to a virtual machine, such as a current skill level or a cost problem. Therefore, the improvement of the performance according to the scale-up method is limited.

On the other hand, the scale-out method is a method for increasing the number of apparatuses that perform tasks, and is a method for increasing the processing performance of the overall task by allowing a plurality of virtual servers or virtual machines to interwork with each other to process the tasks assigned thereto. Since it is possible to add a cautionary server or a virtual machine in parallel without any restriction, the performance improvement according to the scale-out method can be broadly applied.

In the cloud computing or its virtualization environment using the scale-out method, although the user actually performs work using a plurality of virtual servers or virtual machines, the user seems to perform tasks using a single computing device . In this process, certain controls on the network side must be accompanied by proper coordination between virtual machines and virtual machines with different MAC addresses and IP addresses, respectively. For example, on a network connected to virtual servers or virtual machines, control may be required to distribute and deliver packets destined for a specific destination to a plurality of different virtual servers. This distributed control can be performed through a load balancer that distributes the load imposed on the virtual server or virtual machines.

The present invention discloses an apparatus and method for enhancing the performance of a virtualized environment through a scale-out method in cloud computing. Specifically, in the present invention, a virtualization environment monitors computing resources or network resources of a virtual server or a virtual machine, and further enhances the performance of the virtualization environment by interworking a new virtual server or a virtual machine as needed.

Alternatively, if it is determined that the virtual environment control device 100 is required according to the monitoring information MI, the virtual environment control device 100 may allocate resources to change or move some of the created virtual servers or virtual machines. (3) The virtual environment control apparatus 100 determines the lifecycle of the virtual servers 200, 300, and 400 or their virtual machines according to the resource allocation result (for example, , Deletion, etc.) to the virtual servers 200, 300, and 400. The virtual machine control command (VMC) The virtual environment control device 100 then transmits a load control command LC that distributes the load among the virtual servers 200, 300, 400 or their virtual machines according to such a life cycle to the virtual servers 200, 300 And 400, respectively. The virtual servers 200, 300, and 400 generate new virtual machines according to the virtual machine control commands VMC, change, move, or delete existing virtual machines, Lt; RTI ID = 0.0 > and / or < / RTI > At this time, by controlling the network resources allocated to each virtual machine, the workload applied to each virtual machine is controlled as a result.

According to the configuration of FIG. 1, there is provided a virtualization environment for monitoring a computing resource or a network resource of a virtual server or a virtual machine, and performing a scale-up performance improvement according to the result. Therefore, the performance of the virtualization environment can be improved more efficiently than the conventional techniques.

Referring to FIG. 2, the virtualization system 2000 includes a virtual environment control device 100 and a plurality of virtual servers 200 and 300. Here, although two virtual servers 200 and 300 are shown, this is an example, and the virtualization system 2000 may include three or more virtual servers.

The virtual environment control apparatus 100 is connected to a plurality of virtual servers 200 and 300 through the virtual machine managers 210 and 310 and the virtual machines 211 and 212 in the plurality of virtual servers 200 and 300, 213, 311, 312, 313). The virtual environment control device 100 includes a first control unit 110 for generating a virtual machine control command VMC, a second control unit 120 for generating a load control command LC, And a monitoring unit 130 for monitoring the operation of the apparatus.

The first control unit 110 receives the monitoring information IM from the monitoring unit 130 and refers to the virtual servers 200 and 300 and the virtual machines 211, 212, 213, and 311 , 312, and 313, respectively. Specifically, the first control unit 110 determines the states of the virtual servers 200 and 300 and the virtual machines 211, 212, 213, 311, 312, and 313 by referring to the monitoring information IM, (VMC) that creates, deletes, or moves the virtual machines 211, 212, 213, 311, 312, and 313. The generated virtual machine control command VMC is transferred to the virtual machine managers 210 and 310 of the virtual servers 200 and 300.

For example, when the first controller 110 determines that it is necessary to allocate a new virtual machine through the scale-out method with reference to the monitoring information IM, the virtual machine control command VMC And provides it to the virtual servers 200 and 300. Then, the virtual servers 200 and 300 create a new virtual machine in their own according to the received virtual machine control command VMC.

On the contrary, if the first controller 110 determines that it is necessary to delete one of the existing virtual machines (for example, 211) by referring to the monitoring information IM, the virtual machine control command VMC) to the virtual server 200. Then, the virtual server 200 deletes the virtual machine 211 according to the received virtual machine control command VMC.

When a change occurs in the virtual machines 200 and 300 or the virtual machines 211, 212, 213, 311, 312, and 313 according to the virtual machine control command VMC, the second controller 120 generates a virtual machine 313, 311, 312, and 313 are distributed in a balanced manner.

A plurality of virtual servers 200, 300 are computing devices that provide computing resources in a virtualized environment and directly create and manage virtual machines. A plurality of virtual servers 200 and 300 may each comprise a plurality of virtual machines (e.g., 211, 212, 213, or 311, 312) controlled by a virtual machine manager (e.g., 210 or 310) , 313).

The virtual machine managers 210 and 310 are, for example, thin layer software that enables various operating systems to operate in one computer system, and software that enables a virtual machine to be created using a different operating system on one computer It is an enemy composition. The virtual machine managers 210, 310 are often referred to as hypervisors.

The virtual machine managers 210 and 310 control creation, termination, restart, termination, or deletion of the virtual machine. In particular, it is responsible for allocating computing resources (e.g., processors, memory, etc.) to the virtual machine so that the guest operating system of the virtual machine does not interfere with other operating systems. A guest operating system is an operating system that operates independently on a virtual machine, and methods known in the art such as Quality of Service (QoS) isolation can be used to avoid conflicts due to operating system differences between virtual machines .

Each of the virtual machines 211, 212, 213, 311, 312, 313 can execute its own guest operating system, and each guest operating system can be different. Therefore, by using the virtual machines 211, 212, 213, 311, 312, and 313, different operating systems can be simultaneously executed on one virtual server 200.

The second controller 120 controls the network of the virtual machines 211, 212, 213, 311, 312, and 313 using the SDN controller 140 that controls the SDN switches. In this manner, when controlling the network using the SDN controller 140, the SDN controller 140 can control the software-based virtual switch and the hardware-based SDN switch at the same time, There is an advantage that the load of the open stack neuron 121 relatively decreases.

In this case, the open stack neuron 121 may be configured to distribute the load between the virtual machines 211, 212, 213, 311, 312, and 313 according to virtual machine creation, change, movement, deletion, etc. of the first control unit 110 Generates and transmits a network control command (CMD) to the SDN controller (140). The SDN controller 140 generates a load control command LC that controls each SDN switch in accordance with the network control command CMD and the load control command LC is transmitted to the SDN switches so that they Switches) are referred to for controlling the network between the virtual machines 211, 212, 213, 311, 312, 313. As a result, the network resources or the workload between the virtual machines 211, 212, 213, 311, 312, and 313 are controlled to be appropriately distributed. On the other hand, the load control command LC may contain information or instructions for controlling the setting of the respective SDN switches.

In the embodiment of FIG. 4, the virtual machine managers 210 and 310 and the SDN controller 140 are provided with monitoring agents 214, 314 and 141 for collecting the monitoring information IM, respectively. 3, the monitoring information may be obtained from the metering area of the virtual environment control apparatus 100 based on the open stack.

The first controller 110, the second controller 120, the monitoring unit 130, the virtual servers 200 and 300, the virtual machines 211, 212, 213, 311, 312 and 313, Other details not described herein for the administrators 210 and 310 and the virtualization environment 3000 are substantially the same as those described in FIG.

According to the above configuration, since the network is controlled using the SDN controller 140, the hardware-based SDN switch can be controlled simultaneously with the software-based virtual switch, and the SDN controller 140 can completely control the network- So that the load of the open stack neuron can be reduced.

As an embodiment, the monitoring information includes information about computing resources or network resources of the virtual servers 200 and 300 and the virtual machines 211, 212, 213, 311, 312, and 313.

In step S120, the virtual environment control apparatus 100 generates a first control signal (e.g., a control signal) for controlling the life cycles of the virtual machines 211, 212, 213, 311, 312, (VMC in Fig. 2) to the virtual servers 200 and 300. [ At this time, the virtual servers 200 and 300 may generate a new virtual machine, change or move an existing virtual machine, or delete an existing virtual machine according to the first control signal.

In step S130, the virtual environment control device 100 determines whether or not a second control for distributing or controlling the workload of each of the virtual machines 211, 212, 213, 311, 312, and 313 is performed according to the monitoring information and the life- (E.g., LC of FIG. 2) to the virtual servers 200, Accordingly, the network resources of the virtual servers 200 and 300 or the virtual machines 211, 212, 213, 311, 312 and 313 are controlled, and thereby the virtual machines 211, 212, 213, 311 and 312 , 313) are distributed or controlled.

According to the above-described configuration, the computing resources allocated to the virtual server or the virtual machine in the cloud computing can be scaled out as needed, thereby further improving the performance of the cloud computing or virtualization environment. In addition, since scale-out extension is applied, it is possible to improve the performance of cloud computing or virtualization environment relatively freely from hardware constraints.

FIG. 6 is a flow chart illustrating step S130 of FIG. 5 according to another embodiment of the present invention. Referring to FIG. 6, step S130 of FIG. 5 includes steps S131 and S132.

6, the network control of the virtual servers 200 and 300 or the virtual machines 211, 212, 213, 311, 312, and 313 is performed by SDN switches, Controller 140 (e.g., 140 in Fig. 4) is dedicated.

In step S131, the virtual environment control device 100 transmits a network control command (e.g., CMD in FIG. 4) to the SDN controller 140 according to the collected monitoring information and the result of the life cycle control of the virtual machine.

In step S132, the SDN controller 140 transmits a second control signal (e.g., LC in Fig. 4) to the virtual servers 200, 300). At this time, the second control signal may include setting information or command for each SDN switch to control the operation of the SDN switches.

According to the above configuration, since the network is controlled using the SDN controller 140, the hardware-based SDN switch can be controlled simultaneously with the software-based virtual switch, and the SDN controller 140 can completely control the network- The load of the second control unit 120 can be reduced.
