[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] The request processing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the cloud management server is composed of modules such as network, compute, storage, image, gateway, and talk order. Except for the gateway and talk order modules, each of the other modules corresponds to a type of resource in cloud computing. For example, the network module can be responsible for the management and maintenance of resources such as gateway, load balancing, and elastic IP, and the storage can be responsible for the management of resources such as cloud hard disk and object storage. The same applies to the computing and image modules. Gateway and talk order are public modules responsible for the pre-request verification, authentication, diversion, and resource billing of the cloud management system. Each module can be deployed as a separate microservice in different hosts, virtual machines, or containers to reduce the coupling between modules and improve system availability and reliability. After the various requests sent by the front-end page are verified by the unified gateway module, they are received and business operations are performed by the modules they are responsible for. If it involves access to the database, the http request is called to the consistent Raft server cluster, and the Raft server cluster accesses the database and returns the result to the cloud management server. The cloud management server only communicates with the Raft server cluster and the front end of the cloud scheduling system.

[0059] The cloud base server is a control and scheduling platform for atomic operations on cloud computing resources. You can choose to expand the open source OpenStack framework for development and be responsible for the management and maintenance of the underlying resources of cloud computing. It can be mainly divided into Nova, Neutron, Cinder, Swift, Keystone and other modules, which are responsible for computing, networking, block storage, object storage, and identity authentication services respectively. Each module can be deployed as a microservice. After completing the change of cloud computing resources, it sends a callback message to the Raft server cluster for data synchronization and resource information persistence. The cloud base server only communicates with the Raft server cluster.

[0060] The database server cluster is used to persist various types of resource information, including business fields such as name, id, type, specification, and creation time. The cloud management server and the cloud base server share the data of the database server cluster to ensure the consistency of data in each service. The database server cluster can perform persistence operations through various types of databases. Different databases, such as MySQL and MongoDB, can be selected according to whether the resource information is structured. Different cluster deployment methods can be selected according to the amount of data to ensure high data availability. The database server cluster only communicates with the Raft server cluster.

[0061] The Raft server cluster is responsible for coordinating the service processes and data in the distributed system, ensuring the consistency of message transmission and data between the cloud management server and the cloud base server, decoupling the cloud management server and the cloud base server, and avoiding business pollution caused by mutual calls between services. The Raft algorithm ensures the accuracy and consistency of message transmission and data persistence between components.

[0062] In this application environment, the Raft server cluster serves as the interaction hub for various components and can interact with the cloud management server, cloud base server, and database server cluster. The cloud management server only interacts with the front-end and Raft server cluster, and the cloud base server and database server cluster only interact with the Raft server cluster.

[0063] In an exemplary embodiment, Figure 2 As shown, a request processing method is provided, which is applied to Figure 1 The following is an example of the cloud management server in the example, including:

[0064] S201, receiving a resource management request sent by a client.

[0065] Among them, the resource management request can be sent by the client to the cloud management server, and the request format of the resource management request can be a common http request body. The first to receive the resource management request is the gateway module of the cloud management server, which extracts the request body information to perform client authority verification, resource pool verification, and request legitimacy verification. After the verification is successful, the request is forwarded to the business module corresponding to the Infrastructure as a Service IAAS resource. For example, if the IAAS resource is a cloud host, the request is forwarded to the computing business module.

[0066] Optionally, the resource management request in this embodiment may be a resource change request, or may be a resource query request, wherein the resource change request may include resource creation, deletion, update, unbinding, rebinding, etc.

[0067] S202: Generate a database query statement based on the request content of the resource management request.

[0068] In this embodiment, as described in the above embodiment, the gateway module will forward the resource management request to the business module. Optionally, after receiving the resource management request, the business module will perform different verification processes according to different businesses. For example, if the resource management request is to create a cloud host, the business module can verify whether there is a cloud host with the same name, a cloud host supporting network, and whether the storage resources already exist based on the transmitted parameters. Usually, when performing business verification, it generally involves querying the database. At this time, the business module of the cloud management server can generate a database query statement based on the request content of the above resource management request, and obtain the data required for business verification through the database query statement. Alternatively, after the business module receives the resource management request, it is necessary to query the database. For example, when the resource management request is a resource query request, the business module receives the resource query request and needs to query the database according to the information required by the business requirements. At this time, the cloud management server can generate a database query statement based on the request content of the resource management request to query the database. Further, if the resource management request involves the query of multiple databases, query statements for different databases can be generated based on the request content of the resource management request.

[0069] S203, processing the resource management request according to the database query statement and the consistent Raft server cluster.

[0070] Optionally, in this embodiment, the cloud management server can send the database query statement to the database server cluster through the consistency Raft server cluster to process the resource management request. For example, if the resource management request is a resource query request, the database query statement can be sent to the database server cluster through the Raft server cluster to query the data corresponding to the resource query request; if the resource management request is a resource change request, the database query statement can be sent to the database server cluster through the Raft server cluster to obtain verification data for the resource change request.

[0071] In addition, it should be noted that the interaction between the client and the cloud management server selects the commonly used Web request based on the Http protocol encapsulation, including the request header and the request body. Different business modules can be distinguished by different request URLs. For example, the requested page belongs to the cloud host, and the cloud host belongs to the computing module, then the URL can be added with an infix such as "compute". Exemplarily, in this embodiment, the message body of the interaction between the cloud management server, the Raft server cluster, and the cloud base server can be the message body shown in Table 1, wherein the term field represents the internal node term identifier of the Raft server cluster, the seq field represents the request sequence number within the Raft server cluster, and the module represents the business module to which it belongs, which is used for the Raft server cluster to call back the cloud management server or cloud base server interface.

[0072] Table 1

[0073]

[0074] In the above request processing method, the cloud management server receives the resource management request sent by the client, and can generate a database query statement based on the request content of the resource management request, so that the resource management request can be processed according to the database query statement and the consistency server cluster. The interconnection and intercommunication between the cloud management server and the cloud base server are achieved through the consistency server cluster, and the cloud management server and the cloud base server are decoupled. Furthermore, the cloud management server and the cloud base server communicate through the consistency server cluster, which reduces the network congestion caused by direct communication and polling, avoids data loss, and thus improves the information synchronization capability between the cloud management server and the cloud base server.

[0075] This embodiment will explain the detailed process of the cloud management server processing the resource management request according to the database query statement and the Raft server cluster. Figure 3 As shown, the above S203 includes:

[0076] S301, sending a database query statement to a database server cluster through a Raft server cluster.

[0077] In this embodiment, the Raft server cluster acts as an interactive hub, and the database query statement can be sent to the database server cluster through the Raft server cluster. That is to say, in this embodiment, the Raft server cluster plays the role of data forwarding. Optionally, in this embodiment, after receiving the database query statement, the Raft server cluster can mark the request sequence and business module, synchronize messages within the cluster, and record and persist the operation log. After the synchronization is completed, the database query statement is read and forwarded to the database server cluster.

[0078] S302, obtaining the query result returned by the database server cluster through the Raft server cluster.

[0079] Optionally, in this embodiment, after receiving the database query statement, the database server cluster can query the corresponding entry in the database server cluster and send the query result to the Raft server cluster. The Raft server cluster receives the result returned by the database server cluster, synchronizes messages within the cluster, records and persists the operation log, matches the request sequence and business module corresponding to the return, and forwards it to the corresponding business module of the cloud management server.

[0080] In addition, it is understandable that the use of Raft server clusters to uniformly set up log records for various cloud computing resources and business operations makes the log structure, recording information, and persistence methods more reasonable, reducing the time and manpower loss caused by multiple components jointly troubleshooting the same problem.

[0081] S303: Process the resource management request according to the query result.

[0082] Optionally, in this embodiment, if the resource management request is a resource change request, the resource change request can be service-verified according to the query results above. If the service verification of the resource change request is passed, the resource change request is sent to the Raft server cluster. At the same time, an indication can be returned to the client, instructing the client to display the words "resource creation" and the like. Further, after receiving the resource change request, the Raft server cluster can mark the request sequence and service module, encapsulate the request, and after the message synchronization in the Raft server cluster is completed and the log is persisted, the resource change request is sent to the cloud base server. After receiving the resource change request, the cloud base server extracts the service module information from the request header of the resource change request, selects different modules (Nova, Neutron, Cinder, Swift) for processing, performs atomic change operations on the resources, and returns the result to the Raft server cluster after success, and synchronously packages the persistent request for the completion of the resource information change to the Raft server cluster. The Raft server cluster receives the resource change results and resource persistence requests sent by the cloud base server, performs message synchronization within the cluster, outputs logs and persists them after synchronization is completed, extracts database operation statements in the resource persistence request, and sends them to the database server cluster. The database server cluster receives the database operation statements, changes or creates resource entries, and performs atomic change operations on the business modules to be changed. After the change operation is completed, the results are returned to the Raft server cluster. The Raft server cluster receives the database change results, performs message synchronization within the cluster, and persists logs after synchronization is completed, completing the response to the resource change request.

[0083] Optionally, in this embodiment, if the resource management request is a resource query request, the data format of the above query result can be processed according to the data format corresponding to the client, the data format of the query result can be converted into the data format corresponding to the client, the processed query result can be obtained, and the processed query result can be sent to the client.

[0084] In this embodiment, the generated database query statement can be sent to the database server cluster through the Raft server cluster, and the query result returned by the database server cluster can be obtained through the Raft server cluster, so that the resource management request can be processed according to the query result. The cloud management server and the cloud base server are decoupled through the Raft server cluster, and data is forwarded through the Raft server cluster, which ensures the accuracy and consistency of data persistence, thereby ensuring the consistency of message transmission and data between the cloud management and cloud base, and improving the information synchronization capability between the cloud management server and the cloud base server.

[0085] In this embodiment, the specific process of generating a database query statement based on the request content of the received resource management request by the cloud management server is explained. Figure 4 As shown, the above S202 includes:

[0086] S401, obtaining client information according to the request content.

[0087] Optionally, in this embodiment, the cloud management server may extract the request content of the resource management request, and then determine the request body information in the request content as the client information.

[0088] S402: When the information verification of the client passes, a database query statement is generated according to the request content.

[0089] Optionally, in this embodiment, the cloud management server can perform permission verification, resource pool verification, and request legitimacy verification on the client information, and then determine the different services included in the received resource management request based on the request content when the client information verification passes. The process of performing different service verifications on different services involves querying relevant information in the database server cluster. In this scenario, the cloud management server can generate corresponding database query statements based on the service type in the request content. As an optional implementation method, the generated database query statement can also be encapsulated and the encapsulated database query statement can be sent to the Raft server cluster.

[0090] In this embodiment, the client information can be obtained according to the request content of the received resource management request, and the client information can be verified. When the client information verification is passed, a database query statement is generated according to the request content of the received resource management request. This avoids the processing of illegal resource management requests and ensures that the database query statement sent by the cloud management server to the Raft server cluster is a query statement corresponding to a legal resource management request, thereby avoiding the processing of illegal resource management requests.

[0091] In the scenario where the resource management request sent by the client is a resource change request, the cloud base server is required to perform an atomic change operation on the cloud computing resources to complete the resource change request. Figure 5 As shown, a request processing method is provided, which is applied to Figure 1 The cloud base server in the example is used to illustrate, including:

[0092] S501, receiving a resource change request sent by a cloud management server through a consistent Raft server cluster.

[0093] Optionally, in this embodiment, if the resource management request sent by the client is a resource change request, the cloud management server performs a business verification on the resource change request when receiving the resource change request. If the business verification of the resource change request passes, the resource change request is sent to the Raft server cluster. After receiving the resource change request, the Raft server cluster marks the request sequence and business module and encapsulates the request. After the message synchronization in the cluster is completed and the log is persisted, the resource change request is sent to the cloud base server.

[0094] S502: Acquire information of the business module to be changed from the request header of the resource change request.

[0095] In this embodiment, after receiving the resource change request, the cloud base server obtains the business module information to be changed from the request header of the resource change request. For example, the business module to be changed may be Nova, Neutron, Cinder, Swift and other modules in the cloud base server.

[0096] S503: Perform an atomic change operation on the business module to be changed according to the information of the business module to be changed.

[0097] Optionally, in this embodiment, the cloud base server may perform an atomic change operation on the business module to be changed according to the acquired information of the business module to be changed, and return the result to the Raft server cluster upon success.

[0098] In the above request processing method, after the cloud base server receives the resource change request sent by the cloud management server through the consistency server cluster, it can obtain the business module information to be changed from the request header of the resource change request, so that it can perform atomic change operations on the business module to be changed based on the business module information to be changed. In this process, the cloud management server and the cloud base server are interconnected and interoperable through the consistency server cluster, and the cloud management server and the cloud base server are decoupled, so that the cloud base server can receive the resource change request through the consistency server cluster, and perform atomic change operations on the business module to be changed corresponding to the resource change request. Furthermore, the cloud management server and the cloud base server communicate through the consistency server cluster, which reduces the network congestion caused by direct communication and polling, avoids data loss, and thus improves the information synchronization capability between the cloud management server and the cloud base server.

[0099] In some scenarios, after the cloud base service performs an atomic change operation on the business module to be changed, it can also request that the resource change result be persisted in the consistency server. Figure 6 As shown, the above method also includes:

[0100] S601, when the atomic change operation is completed on the business module to be changed, a resource persistence request for the resource change result is generated.

[0101] Optionally, in this embodiment, when the cloud base server completes the atomic change operation on the business module to be changed, it can generate a resource persistence request for the resource change result based on the resource change result, and request to change or create a resource entry of the resource change result.

[0102] S602, sending the resource change result and the resource persistence request to the Raft server cluster; the resource persistence request is used to instruct the Raft server cluster to control the database server cluster to change or create resource entries.

[0103] In this embodiment, the cloud base server can send the resource change result and the resource persistence request of the resource change result to the Raft server cluster. After receiving the resource change result and the resource persistence request sent by the cloud base server, the Raft server cluster synchronizes the messages within the cluster. After the synchronization is completed, the log is output and persisted, and the database operation statement in the resource persistence request is extracted, and the database operation statement is sent to the database server cluster. After receiving the database operation statement, the database server cluster changes or creates the resource entry and returns the result to the Raft server cluster. The Raft server cluster receives the database change result, synchronizes the messages within the cluster, and persists the log after the synchronization is completed to complete the resource change process.

[0104] In this embodiment, when the cloud base server completes the atomic change operation on the business module to be changed, it generates a resource persistence request for the resource change result, and sends the resource change result and the resource persistence request to the Raft server cluster, so that the Raft server cluster can control the database server cluster to change or create resource entries based on the resource persistence request, ensuring the consistency of data in the database server cluster and the cloud base server when the cloud base server performs the atomic change operation on the business module to be changed.
