Description

Technical Field

[0001] The present invention relates to the technical field of distributed systems, and mainly to a service request processing method, device, electronic equipment and medium. Background Art

[0002] In the current distributed object storage system, data synchronization between multiple sites (data centers) can be achieved. Specifically, objects uploaded at one site can be automatically synchronized to other sites. Information such as users and buckets created at the primary site can be automatically synchronized to other sites to ensure that metadata at each site is consistent. When data changes in any data center, all other data centers will monitor the change and perform the same operation, thereby ensuring that data in all data centers is exactly the same. Objects can be downloaded at any site to achieve the effect of remote disaster recovery.

[0003] When users access the object storage system, they can initiate various operation requests to the storage system through the RestAPI interface. After receiving the client's request, the storage system will respond to the corresponding request. Users can send requests to the RestAPI interface of the object storage by IP or domain name. Among them, when sending requests by IP, the request will only be sent to the node where the IP is located. Once the node fails, the service will be inaccessible. Requests sent by domain name will be resolved by domain name, and after resolution, they will be sent to one of the several nodes managed by the domain name.

[0004] In the current distributed storage system, whether through IP or domain name, it can only connect to one data center, and cannot connect to multiple data centers at the same time. In multi-site usage scenarios, it cannot support load balancing between sites. If a site fails, the user's business cannot be automatically and quickly switched to another node. The business can only be continued by modifying the user's business side configuration and connecting the business to another site. The operation is relatively complicated, and the switching configuration process will cause business interruption. This is unacceptable in some usage scenarios, especially in financial services, where there is a great demand for seamless automatic switching of services.

[0005] This shows that a new service request processing method is urgently needed. Summary of the invention

[0055] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to enable the scope of the present application to be fully conveyed to those skilled in the art.

[0056] In one embodiment of the present application, referring to Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for processing a service request in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0057] S101, receiving a first service request sent by a client via a domain name, where the first service request carries a client identifier.

[0058] S102: Determine a target forwarding rule based on the client identifier.

[0059] S103: Determine a target service processing node from a plurality of service processing nodes included in a plurality of data centers based on the domain name, the target forwarding rule, and forwarding rule configuration parameters of each service processing node.

[0060] The forwarding rule configuration parameters of the service processing node include: location information of the service processing node, network configuration information of the service processing node, and forwarding priority information of the service processing node.

[0061] S104: Assemble the first service request based on the source address of the client and the IP address information of the target service processing node to obtain a second service request.

[0062] S105: Send the second service request to a target service processing node.

[0063] In the present application, the method is applied to a domain name management service in a distributed object storage system, wherein the distributed object storage system includes multiple data centers, and one data center includes one or more business processing nodes.

[0064] In this application, a distributed object storage system refers to a distributed storage system for unstructured data objects.

[0065] In this application, a data center (also called a site) is a storage system, also called a storage cluster, and each data center is configured with its own storage gateway and storage pool. A data center can have multiple object storage gateway instances.

[0066] In this application, the domain name management service can be configured in any data center, specifically in the primary data center.

[0067] In the present application, the domain name management service can also be independently configured on an electronic device, and the electronic device is communicatively connected to each data center in the distributed object storage system.

[0068] In this application, multiple data centers in a distributed object storage system can form a multi-site synchronization cluster, and metadata and data between sites will be automatically synchronized.

[0069] In this application, a domain name refers to an identifier on the Internet that is used to identify and locate a computer, server, or network service on the Internet. It is the part after "http: / / www." in a URL. For example, in the URL www.example.com, example.com is the domain name. The main function of a domain name is to map a human-readable string to an IP address on the Internet so that people can use a more memorable domain name to access a website.

[0070] In this application, the domain name management service can manage domain names and configure forwarding rules corresponding to the client, and forward business requests sent to the domain name management service according to the set forwarding rules, so as to achieve load balancing or preferential forwarding of multiple business processing nodes in multiple data centers in multi-site scenarios, thereby realizing the multi-site multi-active function of the distributed object storage system.

[0071] In the present application, in step S101, the client sends a first service request to a domain name management service via a domain name. The domain name is pre-configured by the domain name management service. By resolving the domain name, one or more service processing nodes in each data center can be obtained.

[0072] In the present application, in step S102, the domain name management service can determine the target forwarding rule corresponding to the client currently sending the first service request based on the client identifier. In the present application, different clients can be configured with different forwarding rules to meet the actual needs of the client.

[0073] In the present application, in step S103, multiple business processing nodes configured for the domain name and forwarding rule configuration parameters of each business processing node can be determined according to the domain name, and the target forwarding rule can be used to determine the optimal business processing node that meets the target forwarding rule as the target processing node.

[0074] In the present application, the target forwarding rule may be one or more of a distance priority rule, a network priority rule, a specified priority rule, and a load balancing rule.

[0075] In the present application, the domain name management service can determine its priority under the target forwarding rule based on the forwarding rule configuration parameters of the business processing node (location information of the business processing node, network configuration information of the business processing node, and forwarding priority information of the business processing node).

[0076] For example, for the distance priority rule, the distance between the service processing node and the client can be determined according to the location information of the service processing node and the location information of the client, thereby determining the priority of each service processing node based on the distance.

[0077] In the present application, in step S104, the domain name management service can assemble the first business request according to the determined IP address information of the target business processing node, change the request source to the source address of the client, and determine the target address as the IP address information of the target business processing node. Thus, the second business request assembled in step S105 is forwarded to the optimal IP address so that the target business processing node processes the business request, such as uploading or downloading objects. After completing the processing of the business request, the target business processing node can directly return a response to the client based on the source address of the client. In the present application, the IP address information of the business processing node can be a physical IP or a virtual IP.

[0078] In this application, through the domain name management service, business requests can be sent to the optimal business processing nodes in multiple data centers for processing, so that when a data center fails, the business requests can be automatically switched to another data center according to certain rules, without the user's awareness. This not only avoids the tedious operation of manual business switching, but also avoids business interruptions caused by manual business switching. Not only can business load balancing be performed in multiple sites, but the optimal business processing cluster and processing node can also be selected according to the set rules, which greatly improves the business processing capabilities, read and write performance and disaster recovery capabilities in multi-site scenarios, brings customers a good user experience, and enriches the functions of object storage.

[0079] In one embodiment of the present application, based on the above embodiment, the method further includes the following steps:

[0080] S201: Create a domain name for receiving the first service request.

[0081] S202: configure the IP address information of the service processing nodes of one or more data centers and the forwarding rule configuration parameters of each service processing node for the domain name.

[0082] S203, configuring a forwarding rule for the domain name, wherein the forwarding rule includes one or more of the following: a distance priority rule, a network priority rule, a specified priority rule, and a load balancing rule.

[0083] Based on the above steps S201 to S203, the domain name configured by the domain name management service can be added, deleted, modified and checked.

[0084] Reference Figure 2 , which shows a schematic diagram of the domain name forwarding rule configuration process in this application. In this application, you can first create a domain name and configure the forwarding IP information. In this application, the forwarding IP information includes the IP address information of the business processing node, and the forwarding rule configuration parameters of each business processing node, such as: IP address, IP node distance, interface network configuration, priority, etc. Further configure the forwarding rules of the domain name. After the configuration is completed, the domain name & configured policy information is persisted to complete the configuration of the domain name forwarding rules.

[0085] Specifically, in this application, different domain names can be created for different service requests, and multiple corresponding service processing nodes can be configured for each domain name. In this application, multiple service processing nodes configured for the same domain name refer to nodes in each data center that accept and process the same service.

[0086] In this application, different forwarding rules can also be configured for each domain name according to the actual needs of different services targeted by each domain name. For example, a network priority rule can be configured for services with higher network bandwidth requirements.

[0087] In the present application, when a business processing node changes, the domain name configuration corresponding to the business processing node can also be modified through the domain name management service. Specifically, the business processing nodes configured by the domain name can be added or deleted, and the forwarding rule configuration parameters of the business processing nodes configured by the domain name can also be modified.

[0088] In the present application, since the domain name management service configures the IP address information of multiple business processing nodes in one or more data centers and the forwarding rule configuration parameters of each business processing node for each domain name, the domain name management service can receive business requests sent by the client through the domain name and determine the optimal business processing node for processing the business request from multiple data centers.

[0089] In the present application, in step S203, multiple forwarding rules can be configured for the domain name so that the client can choose according to its own needs. Among them, the load balancing rule can be used as the default forwarding rule. When the client does not select any forwarding rule, the service request sent by the client is processed based on the forwarding rule.

[0090] In the present application, the algorithm logic of the distance priority rule may be: determining the priority of each service processing node for the current service request according to the distance between the service processing node and the client. The algorithm logic of the network priority rule may be: determining the priority of each service processing node for the current service request according to the network configuration of the service processing node. The algorithm logic of the designated priority rule may be: determining the priority according to the service processing priority pre-specified by each service processing node. The algorithm logic of the load balancing rule may be: determining the priority of each service processing node according to the actual load situation of each service processing node.

[0091] In one embodiment of the present application, based on the above embodiment, the method further includes the following steps:

[0092] S1, receiving a rule configuration request sent by a client via a domain name; the rule configuration request carries one or more forwarding rule identifiers.

[0093] S2, associating the client identifier of the client with the forwarding rule corresponding to the forwarding rule identifier in the rule configuration request, and saving to obtain an association table.

[0094] In this embodiment, the step S102 specifically includes: querying the association table based on the client identifier, and determining the forwarding rule associated with the client as the target forwarding rule.

[0095] In this application, users can determine forwarding rules according to their own needs, and send rule configuration requests to the domain name management service through the client based on the domain name, and the domain name management service receives and records the forwarding rules selected by each client. After receiving the service request sent by the client, the forwarding rule pre-selected by the client is determined based on the client's identifier.

[0096] In one embodiment of the present application, based on the above embodiment, when the target forwarding rule determined in step S102 is a distance priority rule, step S103 includes:

[0097] S1031A, determine the service processing node configured for the domain name.

[0098] S1032A: Determine the location information of each service processing node in the service processing nodes configured by the domain name.

[0099] S1033A, determine the location information of the client.

[0100] S1034A: Based on the location information of the client and the location information of each service processing node, determine the service processing node closest to the client as the target service processing node.

[0101] In the present application, after receiving a first service request sent by a client via a domain name, multiple service processing nodes configured for the domain name can be obtained based on the domain name resolution, and the multiple service processing nodes may include: service processing nodes of multiple data centers.

[0102] In the present application, the location information of the client can be determined based on the client identifier carried in the first service request, and the location information of each service processing node can be determined based on the forwarding rule configuration parameters of each of the multiple service processing nodes configured by the domain name. Then, the distance between each service processing node and the client can be calculated, and the service processing node closest to the client is used as the target service processing node.

[0103] In one embodiment of the present application, based on the above embodiment, when the target forwarding rule determined in step S102 is a network priority rule, step S103 includes:

[0104] S1031B: Determine a service processing node for the domain name configuration.

[0105] S1032B: Determine network configuration information of each service processing node in the service processing node configured with the domain name.

[0106] S1033B: determine the service processing node with the best network configuration as the target service processing node.

[0107] In the present application, after receiving a first service request sent by a client via a domain name, multiple service processing nodes configured for the domain name can be obtained based on the domain name resolution, and the multiple service processing nodes may include: service processing nodes of multiple data centers.

[0108] In the present application, the network configuration information of each service processing node can be determined based on the forwarding rule configuration parameters of each of the multiple service processing nodes configured by the domain name, and the service processing node with the nearest network configuration information can be used as the target service processing node.

[0109] In one embodiment of the present application, based on the above embodiment, when the target forwarding rule determined in step S102 is a specified priority rule, step S103 includes:

[0110] S1031C: Determine a service processing node for the domain name configuration.

[0111] S1032C: Determine a designated priority of each service processing node in the service processing nodes configured for the domain name.

[0112] S1033C: Determine the service processing node with the highest designated priority as the target service processing node.

[0113] In the present application, after receiving a first service request sent by a client via a domain name, multiple service processing nodes configured for the domain name can be obtained based on the domain name resolution, and the multiple service processing nodes may include: service processing nodes of multiple data centers.

[0114] In the present application, the designated priority of each service processing node can be determined based on the forwarding priority information in the forwarding rule configuration parameters of each of the multiple service processing nodes configured in the domain name, and the service processing node with the highest designated priority can be used as the target service processing node.

[0115] In one embodiment of the present application, based on the above embodiment, when the target forwarding rule determined in step S102 is a load balancing rule, step S103 includes:

[0116] S1031D: Determine the service processing node configured for the domain name.

[0117] S1032D: query the load information of each service processing node in the service processing nodes configured by the domain name, wherein the load information represents the real-time service request processing volume of the service processing node and / or the real-time response duration of the service processing node.

[0118] S1033D, based on the load information of each business processing node configured in the domain name, determine the business processing node with the smallest load from the business processing nodes configured in the domain name as the target business processing node, and the business processing node with the smallest load is the business processing node with the least real-time business request processing volume and / or the shortest real-time response time of the business processing node.

[0119] In the present application, after receiving a first service request sent by a client via a domain name, multiple service processing nodes configured for the domain name can be obtained based on the domain name resolution, and the multiple service processing nodes may include: service processing nodes of multiple data centers.

[0120] In this application, the domain name management service can query the load information of each business processing node. The load information can be the real-time business request processing volume of each business processing node, or the real-time response time of each business processing node. The real-time business request processing volume and the real-time response time can also be considered at the same time to send the business request to the business processing node with the smallest load. The balanced distribution of business requests is completed to maximize the processing efficiency of the entire distributed object storage system.

[0121] For example, when the business processing nodes configured for domain name A are nodes a, b, and c, the real-time business request processing volume and real-time response time of the three nodes can be queried respectively. If a node has the smallest real-time business request processing volume and the smallest real-time response time, the node is selected as the optimal node. When the minimum real-time business request processing volume and the minimum real-time response time are two different nodes, the optimal node can be determined according to a pre-set load balancing algorithm. For example, when the pre-set load balancing algorithm is to give priority to the node with the smallest real-time response time, the node with the smallest real-time response time is selected as the optimal node.

[0122] In the present application, the domain name management service may also send each received service request to each service processing node in sequence, so that each service processing node processes the service request in turn, thereby achieving balanced distribution of the service requests.

[0123] For ease of understanding, an embodiment is also provided in this application. Figure 3 , Figure 3 This is a logical diagram of the service request processing method described in the embodiment of the present application, such as Figure 3 As shown, the method includes:

[0124] Step 1: Receive a first service request sent by a client via a domain name.

[0125] Step 2: Determine the target forwarding rule based on the client identifier.

[0126] Step 3: determine whether the target forwarding rule is a distance priority rule. If yes, determine the service processing node closest to the client as the target service processing node, and go to step 7. If no, go to step 4.

[0127] Step 4: determine whether the target forwarding rule is a network priority rule. If yes, determine the service processing node with the best network configuration as the target service processing node, and go to step 7. If no, go to step 5.

[0128] Step 5: determine whether the target forwarding rule is a specified priority rule. If yes, determine the service processing node with the highest specified priority as the target service processing node, and go to step 7. If no, go to step 6.

[0129] Step 6, determine whether the target forwarding rule is a load balancing rule, if yes, determine the service processing node with the smallest load as the target service processing node, and go to step 7. If no, determine that the client does not specify a target forwarding rule, use the load balancing rule as the target forwarding rule, and determine the service processing node with the smallest load as the target service processing node.

[0130] Step 7: Assemble the first service request to obtain a second service request, and send the second service request to the IP address corresponding to the target service processing node.

[0131] Step 8: Determine whether the transmission is successful. If the transmission fails, determine the next best service processing node according to the above steps.

[0132] In one embodiment of the present application, based on the above embodiment, in step S203, when multiple forwarding rules are configured for a domain name, the priority of each forwarding rule can also be configured, for example: the priority of the distance priority rule is greater than the network priority rule, which is greater than the specified priority rule, which is greater than the load balancing rule.

[0133] In actual application, the client may request to configure multiple forwarding rules in step S1, so that the domain name management service associates the identifier of the client with the multiple forwarding rule representations and saves them.

[0134] In the case of receiving the service request of the client, multiple target forwarding rules are determined. In this case, if there are multiple nodes that are optimal service processing nodes under the target forwarding rules, the node can be directly used as the target processing node. If the optimal service processing nodes corresponding to the multiple target forwarding rules are different nodes, the optimal service node corresponding to the forwarding rule with the highest priority can be used as the target processing node according to the priority of each forwarding rule. Correspondingly, in the case of failure to send the target processing node, the optimal service node corresponding to the next priority can be used as the target processing node according to the priority order of the forwarding rules.

[0135] For example, assume that the target forwarding rules corresponding to client 1 include: distance priority rule and load balancing rule, and the forwarding rule priority pre-configured by the domain name management service for domain name A is: distance priority rule is greater than load balancing rule, and the multiple business processing nodes configured for domain name A are node a, node b, and node c. Then, when the domain name management service receives the business request sent by client 1 through domain name A, it determines that the distances of node a, node b, and node c from client 1 are: node a is greater than node b, greater than node c, and the load information of each node is node a is greater than node b, greater than node c. Then, according to the forwarding rule priority, node a can be used as the target business processing node, and in the case of failure to send the business request to node a, node c can be used as the target business processing node. Therefore, in this application, the multiple forwarding rules selected by the client and the actual situation of each business processing node can be comprehensively considered to comprehensively determine the optimal business processing node, and further improve the business processing capability, read and write performance, and disaster recovery capability in multi-site scenarios.

[0136] In the present application, the domain name management service can also be used to monitor the monitoring indicators of multiple business processing nodes included in each data center during the domain name resolution process. Specifically, the monitoring indicators may include: the response time of the business processing node, the business processing success rate of the business processing node, the business traffic of the business processing node, the CPU utilization rate of the data center, the memory utilization rate, and the network bandwidth utilization rate.

[0137] In this application, monitoring the response time of each business processing node can evaluate the service performance of the business processing node. Monitoring the business processing success rate of each business processing node can detect the service reliability of the business processing node. Monitoring the CPU usage, memory usage, and network bandwidth usage of each data center can determine the load of each data center, and monitoring the traffic of each business processing node can identify abnormal traffic or potential attacks.

[0138] Specifically, a threshold value may be set for each monitoring indicator, and when a monitoring indicator exceeds the threshold value, it is determined that an abnormality is found.

[0139] In the present application, the monitoring indicators of multiple business processing nodes included in each data center are monitored separately to timely discover abnormal data centers so as to perform abnormal analysis and processing on them.

[0140] In this application, a real-time report of monitoring indicators of each business processing node included in each data center in the distributed object storage system can be generated to display the service status and performance indicators of each current business node. Thus, in the event of an abnormality in a data center, the real-time report can be provided to the technicians for abnormality analysis and processing.

[0141] In the present application, when it is determined that a data center has an abnormality, all business processing nodes of the data center can be regarded as abnormal. In the process of determining the target business processing node based on the client forwarding rules, all business network processing nodes included in the abnormal data center are not considered.

[0142] Furthermore, in the present application, it is also possible to determine whether the forwarding rule of the client is optimal based on the real-time data of the monitoring indicators of each business processing node. If the forwarding rule of the client does not conform to the actual situation of the business processing nodes of each data center, adjustment information about the forwarding rule can be generated to prompt the user to adjust the forwarding rule to optimize service performance and load balancing. For example: assuming that the forwarding rule selected by the user is distance priority, but the response time of the business processing node closest to the client is greater than the preset response time threshold, a prompt message can be sent to the client to prompt the client to select other forwarding rules (for example: network priority rule).
