Description

Technology Field

[0001] The present invention relates to virtual environment state management, and more specifically, to a state management method for supporting state monitoring of virtual environments, such as containers and virtual machines, operating in a Linux operating environment. Background Technology

[0003] Virtual environments running in a Linux environment are recognized as a single regular process and receive scheduling dependent on the operating environment. Representative virtual environments include virtual machines and containers.

[0004] When a virtual machine is managed as a process, it receives the same scheduling as a general process. However, in the case of containers in a Linux environment, they are designed based on Linux Containers (LXC), which are managed by a Cgroup (Control Group), so unit information regarding operating environment resources (CPU, memory, disk, network, etc.) has an inherited form with a tree structure. Figure 1 illustrates a resource relationship structure for Linux containers.

[0005] On the other hand, in a general Linux operating environment, the process management structure is linear (list), so there are no issues with virtual machine scheduling or status monitoring; however, when it comes to container scheduling or status monitoring, the resource relationship structure is different, so approaching it with a linear management structure has limitations.

[0006] In particular, there is a problem where delays occur because it takes a long time to search for the target container before scheduling or taking specific actions depending on the container's state. Prior art literature

Effects of the invention

[0023] As described above, according to the embodiments of the present invention, the management structure of containers operating in a Linux operating environment is created as a tree structure such as a Red-Black Tree based on attributes, thereby enabling rapid state detection when performing container state monitoring.

Brief explanation of the drawing

[0026] Figure 1 is an example of a resource relationship structure for a Linux container, Figure 2 shows a linear management structure for virtual environment monitoring, Figure 3 is an example of creating a tree structure of containers constituting a container group. Figure 4 is an example of a state in which virtual machines are connected in a linear structure to the root of a tree structure. FIG. 5 is a virtual environment state management system according to another embodiment of the present invention. Specific details for implementing the invention

[0027] The present invention will be described in more detail below with reference to the drawings.

[0028] Figure 2 is a diagram illustrating a linear management structure for monitoring a virtual environment. Figure 2 illustrates a situation where multiple pods are created in a cluster. Here, it is assumed that only one container is created in a single pod.

[0029] The lower part of Figure 2 shows a situation where the management structure of containers is operated as a linear management structure. When searching for the container status for scheduling or monitoring, it may take a long time for containers whose resource relationship structure is a tree structure.

[0030] Accordingly, an embodiment of the present invention presents a virtual environment state management method that supports rapid search. It is a technology that supports rapid integrated search for integrated monitoring of all virtual environments operating in a Linux operating environment.

[0031] To this end, in an embodiment of the present invention, a management structure for containers operated in a Linux operating environment is created as a tree structure such as a Red-Black Tree based on the attributes of the containers during scheduling, and a management structure for virtual machines is created as a linear structure based on the same criteria as the containers and connected to manage the state of virtual environments.

[0032] To manage the state of virtual environments, a tree-like management structure is first created for the containers constituting container groups within the virtual environments. This enables rapid, integrated navigation of the containers.

[0033] Figure 3 shows an example of creating a tree structure for the management structure of containers constituting a container group. As in Figure 2, Figure 3 assumes that only one container is created in a single pod, so the pod represents the container.

[0034] Tree structures can be created based on resource relationships assigned to containers, such as CGroups. Furthermore, it is possible to create them based on the names or states of containers, as well as other attributes.

[0035] In Figure 3, the tree structure of the containers is implemented as a Red-Black Tree. However, since the Red-Black Tree is merely one example of a tree structure, it is obvious that it can be replaced with other types of tree structures.

[0036] The root of the tree structure for managing a created container group can be connected to the root of the tree structure for managing another container group. Additionally, it is possible for virtual machines subject to integrated management to be connected to the root of the tree structure for managing the container group in a linear structure.

[0037] Figure 4 illustrates a state in which virtual machines are connected in a linear structure to the root of a tree structure for managing container groups. In this case, the connection criteria between the tree structure and the virtual machines must be the same criteria applied when creating the tree structure.

[0038] Once a management structure is generated by the above method, container status discovery for monitoring the status of containers and virtual machines constituting a container group within the same cluster can be performed in an integrated manner at a high speed based on the generated management structure.

[0039] FIG. 5 is a diagram illustrating the hardware configuration of a virtual environment state management system according to another embodiment of the present invention. The virtual environment state management system according to an embodiment of the present invention can be implemented as a cloud / server system configured to include a communication unit (110), a processor (120), and a storage unit (130) as illustrated.

[0040] The communication unit (110) is a communication interface for connecting to an external network or external device. The processor (120) creates a management structure for virtual environments according to the aforementioned virtual environment state management method and monitors / searches the state of the virtual environments. The storage unit (130) provides storage space necessary for the processor (120) to function and operate.

[0041] So far, a method for managing the state of a virtual environment that supports fast navigation has been described in detail with preferred embodiments.

[0042] In the above embodiment, the management structure of containers operating in a Linux operating environment is created as a tree structure, such as a Red-Black Tree, based on attributes, thereby enabling rapid state detection when performing container state monitoring.

[0043] In addition, in the above embodiment, by creating and connecting a management structure for virtual machines in a linear structure based on the same criteria as containers, it is possible to perform integrated status discovery for integrated monitoring of all virtual environments.

[0044] Meanwhile, it goes without saying that the technical concept of the present invention may also be applied to a computer-readable recording medium containing a computer program that enables the device and method according to the present embodiment to perform their functions. Furthermore, the technical concept according to various embodiments of the present invention may be implemented in the form of computer-readable code recorded on a computer-readable recording medium. A computer-readable recording medium may be any data storage device that can be read by a computer and store data. For example, a computer-readable recording medium may be a ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical disk, hard disk drive, etc. Additionally, computer-readable code or a program stored on a computer-readable recording medium may be transmitted through a network connected between computers.

[0045] Furthermore, although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
