[0002] This application claims priority to Chinese Patent Application No. 202411644426.0, filed on November 18, 2024, entitled "A Cloud Host Management Method, Apparatus, Electronic Device and Readable Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of cloud computing technology, and in particular to a cloud host management method, a cloud host management device, an electronic device, and a computer-readable medium. Background Technology

[0004] In the cloud computing field, various platforms offer different management methods for users to manage their cloud servers. These include VMware vSphere (a virtualization platform) virtualization infrastructure management tool, virt-manager (Virtual Machine Manager, an open-source virtualization management tool), and OpenStack (an open-source cloud computing management platform project). These tools and platforms, when combined, meet users' requirements for different virtualization and cloud computing environments, allowing them to choose the appropriate management method for managing cloud servers and cloud resources. They also provide corresponding interfaces for users to call and perform secondary development to meet their customization needs.

[0005] As user business needs expand, existing management platforms are struggling to meet the demands for batch operation and maintenance management of large cloud server clusters. They also fall short in addressing users' increasingly customized and granular cloud server management scenarios. For example, users may desire to view and monitor the operational status of services within cloud servers without logging in, or they may require batch upgrades of software within cloud servers. Current management platforms cannot easily handle these issues. Furthermore, the cloud server management methods offered by existing platforms do not support users' batch operation and maintenance needs. If batch management and maintenance of cloud servers is required, such as batch distribution of scripts and files to cloud servers, customized secondary development with human intervention is still necessary. Summary of the Invention

[0006] This application provides a cloud server management method, device, electronic device, and computer-readable storage medium to solve the problem that existing management platforms are unable to meet users' needs for batch operation and maintenance management of large cloud server groups and are unable to realize more customized and granular cloud server management scenarios.

[0033] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Referring to Figure 1, a flowchart of the steps of a cloud server management method provided in an embodiment of this application is shown. The cloud server management method is applied to a cloud platform and may specifically include the following steps:

[0035] S1: Obtain the user's cloud server management operation commands.

[0036] S2: Issue cloud server management operation commands in the form of general API requests.

[0037] API is an open interface used for interaction between users and the cloud platform, providing management and operation functions for cloud hosts.

[0038] In this application, a universal API request is used to standardize the management operations of different types of cloud servers. All operation instructions are transmitted through the same interface format, making the system design simpler and maintenance easier. At the same time, the universal API interface supports batch operations, allowing multiple instructions to be issued with a single API request, enabling the management of large-scale cloud servers and improving operational efficiency.

[0039] S3: Perform permission authentication on cloud server management operation commands.

[0040] In one possible implementation, S3 specifically involves: using the username and password to authenticate the user who initiates the cloud host management operation command.

[0041] It should be noted that this step can be implemented by the authentication module. The authentication module is a region-level identity authentication and authorization service, primarily responsible for providing user identity management, authentication, and authorization services. For users calling the Cloud Assistant service, permission is verified. For compliant users, authentication is performed using their username and password. Upon successful authentication, a corresponding token is generated, authorizing access to the Cloud Assistant API module for further operations.

[0042] In this application, usernames and passwords are used for authentication to ensure that only authenticated users can access the cloud assistant service, preventing unauthorized users from performing operations. Token-based authorization avoids transmitting usernames and passwords for every operation, reducing the risk of exposing sensitive information and further enhancing security.

[0043] S4: When the cloud host management operation command passes the authorization authentication, a user identity credential is generated, and the cloud host management operation command is sent to the cloud assistant API service in the corresponding availability zone (AZ) of the cloud host.

[0044] It should be noted that this step can be implemented by the Cloud Assistant scheduling module. The Cloud Assistant scheduling module is a Region-level scheduling module, which is mainly responsible for processing requests issued through the Cloud Assistant OpenAPI, performing relevant permission authentication, and then scheduling them to the Cloud Assistant API service in the corresponding availability zone of the cloud host.

[0045] In this application, permission authentication is performed in the region-level scheduling module, which prevents unauthorized requests from entering the specific availability zone through the scheduling module, thereby preventing invalid or malicious requests from entering the next layer of processing in the cloud platform.

[0046] S5: Verify the parameters of user identity credentials and cloud server management operation commands.

[0047] S6: When the user's identity credentials and cloud host management operation instructions are verified, the cloud host management operation instructions will be sent to the cloud assistant agent service of the corresponding computing node of the cloud host.

[0048] In one possible implementation, in S6, the cloud host management operation instructions are sent to the cloud assistant agent service of the corresponding computing node of the cloud host. Specifically, based on the watch (event listening) mechanism of the distributed key-value storage system (etc daemon, ETCD), the cloud host management operation instructions are sent to the cloud assistant agent service of the corresponding computing node of the cloud host.

[0049] It should be noted that this step can be implemented by the Cloud Assistant API module. The Cloud Assistant API module receives REST (Representational State Transfer) requests from the Cloud Assistant scheduling module and further verifies the parameters and user token in the request. Simultaneously, the ETCD database stores metadata information related to the cloud host and its corresponding compute node information. The Cloud Assistant API module can obtain the compute node information of the corresponding cloud host. Then, using the watch mechanism based on a distributed key-value storage system, the Cloud Assistant API module, located on the control node, successfully forwards the request to the Cloud Assistant Aagent module on the corresponding compute node of the cloud host.

[0050] The watch mechanism is primarily an event monitoring mechanism that allows applications to monitor changes to specific keys in ETCD (Enterprise Transfer Code), i.e., one or a group of keys, and receive notifications when changes occur. The watch mechanism essentially relies on resource revision numbers. In this design pattern, each update to a specific key increases the atomicity of the revision, and the detection of change events is achieved by comparing revision values. Based on the watch mechanism, after receiving a request, the Cloud Assistant API module selects the Cloud Assistant Agent module on the node where the cloud host resides, and distributes the request task to ETCD. The Cloud Assistant Agent module listens for changes in task information through ETCD's watch mechanism and receives notifications, thus receiving script commands from the Cloud Assistant API module to execute the task request. Simultaneously, for ETCD data storage, several data compression tasks will run, periodically compressing and cleaning up expired data to ensure that the ETCD data storage volume does not exceed the cluster's capacity limit, guaranteeing cluster reliability.

[0051] S7: Parse and execute cloud server management operation commands.

[0052] In one possible implementation, S7 specifically includes sub-steps S701 to S704:

[0053] S701: Parse cloud server management operation commands.

[0054] S702: Arrangement operation execution logic.

[0055] S703: By calling the general interface of the guest agent (QGA, QEMU Guest Agent), the QGA service is invoked to send the instruction script corresponding to the cloud host management operation instructions to the cloud host for execution.

[0056] QGA is a tool that helps improve cloud host management and monitoring. It provides a standardized approach to enable more interaction and communication between the host system and the cloud host, thereby improving the manageability and security of the virtualization environment.

[0057] Optionally, the QGA generic interface is configured in Libvirt (a virtualization management toolset). Libvirt is an open-source virtualization management tool and library that provides a set of APIs and command-line tools for managing different virtualization technologies. Libvirt's main goal is to provide a consistent management interface for different virtualization technologies to simplify the management and integration of cloud hosts.

[0058] The QGA service is essentially a QGA client (QEMU Guest Agent Client) process running inside the cloud host, providing specific QGA services. It is created by installing the relevant software into the image template and running in the background after the cloud host is created. The Cloud Assistant Agent module triggers QGA execution commands by calling Libvirt's interface and passes the return value to the Cloud Assistant Agent module.

[0059] S704: Collect the return data after the QGA service is executed.

[0060] Furthermore, the collected data is organized and returned to the Cloud Assistant API module, which in turn pushes it to the Cloud Assistant scheduling module. The asynchronous statistical task of the Cloud Assistant scheduling module persistently stores the execution results in the data storage module.

[0061] In this application, the standardized interface provided by QGA enables the host system to communicate and manage the virtual machine in a standardized manner. This standardized approach avoids inconsistencies between different virtualization platforms and simplifies cross-platform management operations. Simultaneously, QGA acts as a client process within the cloud host, allowing the host machine to directly transmit operation commands to the cloud host for execution via the QGA interface, avoiding the latency and instability of traditional network communication and improving execution efficiency and stability.

[0062] S8: Storage cloud host management operation commands and corresponding execution results.

[0063] Optionally, the execution result includes: execution successful, execution failed, and execution timed out.

[0064] It should be noted that the issued cloud server management operation commands are recorded in the database storage module. Users can also create frequently used commands to achieve unified management and batch issuance of command content. User-issued script command execution records are also stored in the database storage module for subsequent user queries of execution records and statistical analysis of execution results. Each execution record is persistently processed; whether a task succeeds or fails, its status will be updated in the execution record based on the script execution result within the cloud server. If script execution times out, the service will stop the task and update the script execution result to a timeout status. Each execution record is clearly and accurately recorded, allowing users to query script task execution results and choose to reissue or execute the next task. Since each command issuance generates an execution record, the idempotency and consistency of each script command execution result are guaranteed. Simultaneously, the cloud assistant scheduling module performs traffic processing and security audits to ensure task execution reliability and prevent users from issuing dangerous commands or scripts.

[0065] Optionally, the data storage module is a MariaDB (open-source relational database) cluster, also a Region-level database cluster. It stores records of user commands issued to the cloud assistant service, as well as records of operation execution results. This allows users to subsequently query execution records and corresponding results. The Region-level database ensures high availability of the database storage module.

[0066] Furthermore, this application provides a unified OpenAPI interface to achieve unified management of cloud servers. It supports batch operation and maintenance management capabilities for cloud servers through general interface calls. This includes executing general commands, distributing and executing script files such as Shell (command-line interpreter), PowerShell (command-line tool and scripting language), Bat (batch file), and Python (programming language), as well as collecting and aggregating command and script execution results. Users can utilize the cloud assistant platform to perform common usage scenarios such as installing and uninstalling software, starting and stopping services, and upgrading services within cloud servers. They can also rely on the cloud assistant management channel capabilities to achieve customized operation and maintenance operations and internal service monitoring, including memory and CPU (Central Processing Unit) resource monitoring. It adopts a general OpenAPI interface to provide granular management capabilities for cloud servers in a cloud computing environment, providing a complete new cloud server batch operation and maintenance channel and service monitoring system.

[0067] Furthermore, in this application, the entire process of cloud server operation and maintenance management is password-free, login-free, and does not require the use of jump servers, greatly reducing operation and maintenance management costs and complexity. The cloud assistant platform can realize user authentication, traffic resource distribution, operation record storage and query, and operation command whitelist restriction, making it more secure and efficient. At the same time, the cloud assistant management channel system mainly uses QGA to realize the interaction between the host machine and the cloud server, which does not rely on the network, and the communication is more efficient and stable compared to TCP (Transmission Control Protocol) network.

[0068] Furthermore, this application provides a unified authentication module, offering user-friendly support for batch processing scenarios. It also provides a unified data storage module, ensuring that data processing records are traceable and verifiable. Finally, it provides a unified cloud assistant scheduling module, guaranteeing secure and identifiable user operations throughout the entire process, controllable traffic concurrency, and rapid resource scheduling. Based on QGA channel encapsulation, it possesses good data exchange stability and scalability. The proposed and implemented cloud assistant management channel system achieves multiple functions including user authentication, security auditing, traffic limiting, batch cloud host operation and maintenance, and service management, offering numerous advantages such as security, efficiency, ease of control, and reliable service.

[0069] Furthermore, this application implements a cloud assistant service system under a multi-availability zone architecture, providing batch management capabilities for cloud hosts in multi-availability zone scenarios. Compared with existing technologies, this application's cloud assistant management channel system adapts to multi-availability zone resource pools, achieving a flexible and adaptable architecture that aligns with the mainstream trends in current cloud computing underlying service architectures. Simultaneously, the multi-availability zone architecture design also ensures the stability and high availability of the cloud assistant management channel system service itself.

[0071] This application adopts a general OpenAPI interface to issue cloud host management operation instructions in the form of general API requests, thereby improving the fine-grained management capabilities of cloud hosts in the cloud computing environment.
