The second operation information is the operation information whose reception time is closest to the first operation information in the historical received information. The historical received information is the operation information received before the first operation information. Both the first operation information and the second operation information are used to update the resource information of the virtual machine.

[0011] The first determining module is used to determine the status information of the virtual machine based on the first matching result and the resource information of the virtual machine.

[0028] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0029] See Figure 1 , Figure 1 A flowchart of a state information determination method for edge computing provided in this disclosure embodiment is shown below. Figure 1 As shown, the method for determining state information for edge computing includes the following steps:

[0030] Step S101: Receive first operation information and obtain the resource information of the virtual machine of the edge device according to the first operation information.

[0031] It should be noted that the embodiments of this disclosure can be applied to servers, and the servers can adopt a Kubernetes architecture. That is, the execution entity of the embodiments of this disclosure can be a server, and the relationship between the server and edge devices can be found in [reference needed]. Figure 2 As shown. Figure 2As shown, the edge device includes at least two edge Kubernetes clusters, and each edge Kubernetes cluster may include an Edge Agent, an API server, and an ETCD (database). The aforementioned Kubernetes clusters may also include virtual machines. The Edge Agent may include an Edge Hub. The server can be referred to as the cloud or cloud server. The cloud server may include a server Kubernetes cluster, a state machine (which can transition between states 1, 2, 3, and 4), a database (DB), and functional modules (which may include billing and alarm modules). The server Kubernetes cluster may include an Edge Controller, an API server, and an ETCD (database, which can be understood as the first database in the following text). The state machine can monitor the API server through a list watch mechanism to obtain changes in resource information. The database (DB) can be understood as the second database in the following text. The Edge Controller may include a Cloud Hub. The functional modules can query information about virtual machines stored in the ETCD through the API server.

[0032] It's worth noting that when the state machine monitors the API server via a list watch mechanism, it achieves the listening of virtual machine resource information change events, decoupling user operations (i.e., the first operation information) from virtual machine state information, resulting in high scalability. This decoupling also makes the division of labor among the modules clearer.

[0033] In addition, by utilizing the list watch mechanism and subscribing to resource update events, resource information becomes more accurate, enhancing real-time performance.

[0034] The first operation information can be operation information input by the user. Optionally, the user can input the first operation information through an external device connected to the server. The first operation information can also be referred to as the input information corresponding to the user's operation.

[0035] As an optional implementation, the server may include a state machine that receives first operation information and obtains resource information of the virtual machine of the edge device based on the first operation information, including:

[0036] Receive the first operation information;

[0037] If the first operation information is verified, the resource information of the virtual machine of the edge device is obtained according to the first operation information.

[0038] The verification of the first operation information, also known as the verification of the legality of the first operation information, is performed only when the verification is successful. In this way, the resource information of the virtual machine is obtained based on the first operation information, thus improving the security of resource information acquisition.

[0039] The specific operation for verifying the legality of the first operation information is not limited here. Optionally, the user information carried in the first operation information can be verified, or the tag information carried in the first operation information can be verified. Only when the user information or tag information matches the preset information is the first operation information verified as passed.

[0040] In this embodiment of the disclosure, when the first operation information is verified, the resource information of the virtual machine of the edge device is obtained according to the first operation information, which reduces the occurrence of the phenomenon that the resource information is mistakenly obtained due to the incorrect input of operation information, thereby improving the security of resource information acquisition.

[0041] It should be noted that the specific method for obtaining virtual machine resource information based on the first operation information is not limited here.

[0042] As an optional implementation, receiving first operation information and obtaining resource information of the virtual machine of the edge device based on the first operation information includes:

[0043] Receive the first operation information;

[0044] Send the first operation information to the edge device;

[0045] Receive the virtual machine's resource information returned by the edge device in response to the first operation information.

[0046] In this embodiment of the disclosure, the server can send first operation information to the edge device, and the virtual machine on the edge device can execute the first operation information and generate corresponding resource information. The edge device can then send the resource information to the server, enabling the server to obtain the resource information. This allows for higher accuracy of the resource information obtained by the server.

[0047] As another optional implementation, the step of receiving first operation information and obtaining the virtual machine resource information of the edge device according to the first operation information includes:

[0048] Receive the first operation information;

[0049] The resource information of the virtual machine, which is stored in advance, is obtained based on the first operation information.

[0050] The difference between this embodiment and the above embodiment is that in the above embodiment, when the server receives the first operation information, it can send the first operation information to the edge device so that the edge device can return the resource information of the virtual machine according to the first operation information; while in this embodiment, when the server receives the first operation information, it can obtain the pre-stored resource information of the virtual machine according to the first operation information.

[0051] In other words, in this embodiment of the disclosure, the storage location of the virtual machine's resource information is located locally on the server, while in the above embodiments, the edge device needs to generate the virtual machine's resource information based on the first operation information, that is, the virtual machine's resource information is generated in real time.

[0052] In this embodiment of the disclosure, the resource information of the virtual machine is obtained from the pre-stored information based on the first operation information. This reduces the interaction between the server and the edge device and improves the efficiency of obtaining the resource information of the virtual machine.

[0053] It should be noted that the edge device can collect the virtual machine's resource information at preset intervals and synchronize the above resource information to the server, that is, send the above resource information to the server, and the above resource information can be stored locally on the server.

[0054] It should be noted that the specific content of the resource information is not limited here. As an optional implementation method, the resource information includes the following information: virtual machine status information and configuration information, etc.

[0055] As an optional implementation, receiving the first operation information includes:

[0056] If it fails to obtain the first target operation information from the first database, but obtains the second target operation information from the second database, the first operation information is received. The first database is connected to the edge device, and the second database is connected to the first database. Both the first target operation information and the second target operation information are used to update the resource information of the virtual machine, and the first target operation information and the second target operation information correspond to each other.

[0057] After determining the virtual machine's status information based on the first matching result and the virtual machine's resource information, the method further includes:

[0058] The virtual machine's state information is stored in the second database, and the second target operation information is updated according to the first operation information.

[0059] It should be noted that the server may include two databases, a first database and a second database, both of which can be used to store operation information and virtual machine resource information. The storage format of the resource information in the first and second databases may differ, but the actual content can be the same.

[0060] Furthermore, the second database can be referred to as the business database. Virtual machine status information can also be stored in the second database, and target processing can be performed based on this virtual machine status information. Target processing can include at least one of the following: alarm notification, billing, and execution. It should be noted that the business information stored in the second database can include at least one of the following: intermediate business status information and final business status information.

[0061] The failure to retrieve the first target operation information from the first database can be understood as follows: the first database does not store the first target operation information, or the first target operation information stored in the first database is invalid, or the first target operation information stored in the first database is in the wrong format. However, if the second target operation information can be retrieved from the second database, and the first and second target operation information correspond, it means that the first and second target operation information are mutually matching operation information. In this case, if the second target operation information is only stored in the second database, and the first target operation information stored in the first database is invalid, missing, or in the wrong format, it cannot be confirmed whether the second target operation information stored in the second database is accurate.

[0062] In this embodiment of the disclosure, when it fails to obtain the first target operation information from the first database, but obtains the second target operation information from the second database, the first operation information is received, and the second target operation information is updated according to the first operation information. This can improve the accuracy of the second target operation information, reduce the differences between the second target operation information, the first target operation information, and the first operation information, and enhance stability.

[0063] It should be noted that this implementation method can also be referred to as the server's state machine, which reduces the differences between the second target operation information, the first target operation information, and the first operation information through a full synchronization mechanism, thereby enhancing stability.

[0064] As an optional implementation, it also includes:

[0065] If the first target operation information is obtained from the first database and the second target operation information is obtained from the second database, a third matching result of the first target operation information and the second target operation information is determined;

[0066] Based on the third matching result, update the second target operation information.

[0067] In this embodiment of the disclosure, when first target operation information is obtained from the first database and second target operation information is obtained from the second database, the second target operation information can be updated according to the third matching result of the first target operation information and the second target operation information. In this way, the accuracy of the second target operation information can be further guaranteed.

[0068] As an optional implementation, updating the second target operation information based on the third matching result includes:

[0069] If the third matching result is that the first target operation information and the second target operation information do not match, the second target operation information is updated according to the first target operation information.

[0070] Wherein, if the third matching result is a match between the first target operation information and the second target operation information, the second target operation information remains unchanged.

[0071] In this embodiment of the disclosure, when the first target operation information and the second target operation information do not match, the second target operation information is updated according to the first target operation information. That is, the content of the second target operation information is replaced with the content of the first target operation information, or the content in the second target operation information that is different from the first target operation information is replaced with the content corresponding to the first target operation information. In other words, the content of the first target operation information is taken as the standard, and the consistency between the first target operation information and the second target operation information is maintained. Since the first database is connected to the edge device, the accuracy of the first target operation information is higher than that of the second target operation information. In this way, the consistency and accuracy of the first target operation information and the second target operation information can be improved.

[0072] Step S102: Obtain the pre-stored second operation information and determine the first matching result between the second operation information and the first operation information. The second operation information is the operation information whose reception time is closest to the first operation information in the historical received information. The historical received information is the operation information received before the first operation information. Both the first operation information and the second operation information are used to update the resource information of the virtual machine.

[0073] The second operation information can also be referred to as the operation information received by the server at the last time. In other words, the second operation information is the operation information received by the server before the first operation information.

[0074] Step S103: Determine the status information of the virtual machine based on the first matching result and the resource information of the virtual machine.

[0075] It should be noted that the virtual machine's state information can also be referred to as the intermediate state of the business. After determining the virtual machine's state information, the final state of the business can be determined based on the intermediate state and the virtual machine's resource information. The intermediate state and the final state of the business can be the same or different.

[0076] In addition, the final state of the above services can be determined based on information such as user operation information, virtual machine resource information, state update time, and user operation time, thereby ensuring the accuracy of virtual machine state information.

[0077] It's important to note that virtual machine status information can be understood as display information. By showcasing the virtual machine's operational status through this information, the virtual machine's condition can be represented more intuitively, improving the user experience. In this way, the true state of the virtual machine can be accurately monitored using the aforementioned status information.

[0078] The actual state information of the virtual machine may differ from the state information of the virtual machine mentioned above. Furthermore, depending on the usage scenario, the state information can be specifically changed based on the user's first operation information, thereby enhancing the diversity and flexibility of the state information and improving the user experience. During the above changes, the actual state information of the virtual machine remains unchanged, and only the state information of the virtual machine is changed by the user's first operation information.

[0079] In this embodiment of the disclosure, through steps S101 to S103, the status information of the virtual machine is determined based on the first matching result of the second operation information and the first operation information, as well as the resource information of the virtual machine. That is, the status information of the virtual machine can be accurately determined based on the first matching result and the resource information of the virtual machine, without the need to set up multiple monitoring nodes in the edge device, thereby saving usage costs.

[0080] The first operation information and the second operation information may or may not match.

[0081] As an optional implementation, determining the virtual machine's state information based on the first matching result and the virtual machine's resource information includes:

[0082] If the first matching result indicates that the second operation information does not match the first operation information, the virtual machine's status information is updated based on the first operation information and the virtual machine's resource information; or,

[0083] If the first matching result is that the second operation information matches the first operation information, a second matching result with a first occurrence time and a second occurrence time is determined, and the state information of the virtual machine is determined based on the second matching result and the resource information of the virtual machine. The first occurrence time is the time when the first operation information updates the resource information of the virtual machine, and the second occurrence time is the time when the second operation information updates the resource information of the virtual machine.

[0084] The first operation information can be referred to as the new operation information, while the second operation information can be referred to as the existing operation information.

[0085] The first occurrence time and the second occurrence time can be understood as the effective time. That is, the first occurrence time can be understood as the effective time when the first operation information updates the resource information of the virtual machine, and the second occurrence time can be understood as the effective time when the second operation information updates the resource information of the virtual machine.

[0086] In this embodiment of the disclosure, when the first matching result is that the second operation information does not match the first operation information, the virtual machine status information can be directly updated based on the first operation information and the virtual machine resource information; when the first matching result is that the second operation information matches the first operation information, the virtual machine status information is determined based on the second matching result of the first occurrence time and the second occurrence time and the virtual machine resource information. In this way, different methods for determining the virtual machine status information can be determined according to different first matching results, thereby improving the diversity and flexibility of the methods for determining the virtual machine status information.

[0087] Meanwhile, when the first matching result is that the second operation information matches the first operation information, it is necessary to determine the virtual machine's status information based on the second matching result of the first occurrence time and the second occurrence time and the virtual machine's resource information, thereby further improving the accuracy of determining the virtual machine's status information.

[0088] As an optional implementation, determining the virtual machine's state information based on the second matching result and the virtual machine's resource information includes:

[0089] If the second matching result indicates a mismatch between the first occurrence time and the second occurrence time, the virtual machine's status information is updated based on the first operation information and the virtual machine's resource information; or,

[0090] If the second matching result is a match between the first occurrence time and the second occurrence time, the virtual machine's state information is kept unchanged based on the first operation information and the virtual machine's resource information.

[0091] In this embodiment of the disclosure, when the first occurrence time and the second occurrence time do not match, the virtual machine's state information can be updated. When the first occurrence time and the second occurrence time match, the virtual machine's state information remains unchanged. This further increases the diversity and flexibility of the way the virtual machine's state information is determined.

[0092] like Figure 3 As shown in the diagram, this disclosure provides a structural schematic of a state information determination device for edge computing. Figure 3 As shown, the state information determination device 300 for edge computing includes:

[0094] The acquisition module 302 is used to acquire pre-stored second operation information and determine a first matching result between the second operation information and the first operation information. The second operation information is the operation information whose reception time is closest to the first operation information in the historical received information. The historical received information is the operation information received before the first operation information. Both the first operation information and the second operation information are used to update the resource information of the virtual machine.

[0095] The first determining module 303 is used to determine the status information of the virtual machine based on the first matching result and the resource information of the virtual machine.

To avoid repetition, it will not be described again here.
