[0025] The exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted below for clarity and conciseness.

[0026] Figure 1 is a flowchart of a traffic scheduling method provided according to an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation where there is a network anomaly at the input port of the primary computer room. This method can be executed by a traffic scheduling device, which can be implemented in software and / or hardware and is configured in the standby computer room of the cloud computing platform. As Figure 1 shown, the traffic scheduling method of this embodiment may include:

[0027] S101, obtain a first request to be processed from the domain name system; the first request is obtained by rewriting a second request through the domain name system when there is a network anomaly at the input port of the primary computer room;

[0028] S102, send the first request to the primary computer room through the data channel between the standby computer room and the primary computer room, and the primary computer room processes the first request to obtain a processing result.

[0029] Among them, business services are deployed in the primary computer room. Optionally, the business services include a scheduling service and microservices. The scheduling service is used to schedule access traffic and schedule the access traffic to other computer rooms, and other computer rooms process the access traffic based on the microservices deployed in the primary computer room. The microservices are used to support the cloud computing platform to provide services such as resource management, application management, operation and maintenance management, and access management to the outside world.

[0030] Among them, other computer rooms refer to computer rooms in the cloud computing platform other than the primary computer room. Optionally, among all the computer rooms included in the cloud computing platform, business services are only deployed in the primary computer room, and no business services are deployed in other computer rooms.

[0031] Inside the cloud computing platform, other computer rooms in the cloud computing platform are communicatively connected to the primary computer room through internal interfaces. Other computer rooms access the primary computer room through the internal interfaces (private APIs) configured in the primary computer room to access the business services deployed in the primary computer room. Optionally, other computer rooms call the internal interfaces in the http (Hyper Text Transfer Protocol) manner.

[0032] Optionally, other computer rooms with data channels to the primary computer room are backup computer rooms. The number of backup computer rooms is at least one, and the specific number of backup computer rooms is not limited here and is determined according to the actual situation. Without considering communication costs, multiple backup computer rooms can be set up in the cloud computing platform.

[0033] The primary computer room is configured with an input port. The input interface of the primary computer room refers to the network entrance of the primary computer room. Through the input port of the primary computer room, the access traffic obtained from the outside can be input into the primary computer room, and the primary computer room provides business access externally. Inside the cloud computing platform, the backup computer room and the primary computer room perform data interaction based on the data channel. Among them, the data channel between the backup computer room and the primary computer room is a dedicated channel between the two. The data channel is independent of the input port of the primary computer room, and the availability of the data channel has nothing to do with the availability of the input port of the primary computer room. When there is an abnormality in the input interface of the primary computer room, the backup computer room can send a first request to the primary computer room through the data channel.

[0034] Among them, the first request is obtained by rewriting the second request through the domain name system when there is a network abnormality in the input port of the primary computer room. Optionally, the domain name system rewrites the domain name pointed to by the second request. If there is no network abnormality in the input port of the primary computer room, the domain name system does not need to rewrite the second request and directly sends it to the primary computer room through the domain name system.

[0035] The first request and the second request are access requests generated by the user side and are used to request the cloud computing platform to provide business services. There are differences between the domain names pointed to by the first request and the second request. Specifically, the first request points to the domain name of the backup computer room, and the second request points to the domain name of the primary computer room. The first request is sent to the primary computer room through the backup computer room, and the second request is sent to the primary computer room through the domain name system.

[0036] It can be understood that when there is an abnormality in the input interface of the primary computer room, the second request pointing to the primary computer room cannot be input into the primary computer room through the input interface. The first request is obtained by rewriting the domain name pointed to by the second request through the domain name system, so that the first request points to the backup computer room.

[0037] Optionally, an input interface is also configured in the standby computer room. The Domain Name System sends the first request to the standby computer room through the input interface of the standby computer room. The standby computer room sends the first request to the primary computer room through the data channel between the standby computer room and the primary computer room, and the primary computer room processes the first request to obtain a processing result. This is equivalent to invoking the scheduling service deployed in the primary computer room through the standby computer room to schedule the first request, and using the microservices deployed in the primary computer room to provide matching business services for the first request. It should be noted that only the input port in the primary computer room has a network anomaly, and the business services deployed in the primary computer room, such as the scheduling service and the microservices, are normal.

[0038] In an alternative embodiment, the data channel is obtained by creating a peer connection between the primary computer room and the standby computer room.

[0039] Among them, a peer connection refers to a network connection between two Virtual Private Clouds (VPCs). When the two parties of the peer connection conduct data communication, they do not distinguish which one is the service requester and which one is the service provider. By creating a peer connection between the primary computer room and the standby computer room, a data channel between the two can be obtained. It can be understood that the data channel between the standby computer room and the primary computer room can also be created by other means, not limited to the peer connection method, which is not limited here and is specifically determined according to actual business requirements. It should be noted that regardless of the method of creating the data channel, in the case of an anomaly in the input interface of the primary computer room, the availability of the data channel needs to be ensured. The above technical solution provides a practical data channel creation solution, enabling the standby computer room to invoke the business services deployed in the primary computer room when there is a network anomaly in the input port of the primary computer room, providing technical support for ensuring the availability of business services in the cloud computing platform.

[0040] The embodiments of the present disclosure provide a service disaster recovery solution. By setting up a data channel between the standby computer room and the primary computer room, in the case of a network anomaly in the input port of the primary computer room, the standby computer room can send the first request to be processed obtained from the Domain Name System to the primary computer room through the data channel, and the primary computer room processes the first request to obtain a processing result, improving the availability of business services in the cloud computing platform. The technical solution provided by the embodiments of the present disclosure supports deploying business services only in the primary computer room, which is beneficial to reducing the disaster recovery cost of the cloud computing platform.

[0041] Figure 2 It is a flowchart of another traffic scheduling method provided according to the embodiments of the present disclosure; this embodiment is an alternative solution proposed based on the above embodiment. Specifically, the embodiments of the present disclosure refine how to generate the first request.

[0042] See Figure 2 , the traffic scheduling method provided in this embodiment includes:

[0043] S201, when it is detected through the Domain Name System that there is a network anomaly at the input port of the primary computer room, obtain the alias record of the primary computer room through the Domain Name System.

[0044] The Domain Name System detects the network status of the input port of the primary computer room. If the Domain Name System detects that there is a network anomaly at the input port of the primary computer room, the Domain Name System obtains the alias record of the primary computer room.

[0045] Among them, the alias record (CNAME) allows multiple names to be mapped to the same server IP. In the case where multiple domain names point to the same server IP, one domain name can be set as an A record to point to the server IP, and then other domain names can be set as aliases (i.e., CNAME) and associated with the domain name of the A record. When the server IP address changes, it is not necessary to change the domain name pointing one by one. Only the domain name of the A record needs to be changed to the new IP of the server, and other domain names set as aliases (i.e., CNAME) will automatically point to the new IP address.

[0046] S202, modify the alias record based on the standby domain name of the standby computer room through the Domain Name System to rewrite the domain name pointed to by the second request to obtain the first request.

[0047] The primary computer room is the key computer room for traffic scheduling. The second request in the cloud computing platform will be preferentially input into the primary computer room and then scheduled to other computer rooms through the scheduling service deployed in the primary computer room. That is to say, the second request generally points to the primary domain name. Among them, the primary domain name refers to the domain name of the primary computer room. The Domain Name System modifies the alias record based on the standby domain name of the standby computer room. The standby domain name refers to the domain name of the standby computer room. Specifically, the Domain Name System modifies the A record associated with the alias record based on the standby domain name of the standby computer room. Modify the domain name pointed to by the second request from the primary domain name to the standby domain name.

[0048] By modifying the domain name pointed to by the second request through the Domain Name System, the first request can be obtained. The second request and the first request only differ in the domain name they point to. The second request points to the primary domain name, and the first request points to the standby domain name. The first request is input into the standby computer room through the input port of the standby computer room, and the first request is sent to the primary computer room through the standby computer room, and the primary computer room processes the first request to obtain the processing result.

[0049] In an embodiment of the present disclosure, when a network anomaly is detected at the input port of the primary computer room through the Domain Name System (DNS), the alias record of the primary computer room is obtained through the DNS, the alias record is modified based on the standby domain name of the standby computer room through the DNS, and the domain name pointed to by the second request is rewritten to obtain the first request, so that the first request can be obtained by the standby computer room. The first request is sent to the primary computer room by the standby computer room, and then the primary computer room processes the first request. By modifying the alias record and rewriting the domain name pointed to by the second request, the embodiment of the present disclosure improves the domain name resolution efficiency, shortens the domain name resolution duration, and reduces the impact of the primary-standby switch on the business service.

[0050] In an alternative embodiment, the method further includes: checking the network status of the primary computer room and at least two candidate computer rooms through the DNS; if the DNS detects a network anomaly at the input port of the primary computer room, selecting a standby computer room from the candidate computer rooms based on the inspection results of the candidate computer rooms through the DNS, and determining the standby domain name of the standby computer room.

[0051] Among them, the candidate computer rooms are communicatively connected to the primary computer room through a data channel, and the standby computer room is generated from the candidate computer rooms. The network status of the primary computer room and at least two candidate computer rooms is checked through the DNS to check whether there is a network anomaly at the input ports of the primary computer room and the standby computer room, and the inspection results of the primary computer room and the standby computer room are obtained. Among them, the inspection results include input port network anomaly and input port network anomaly.

[0052] If the inspection result of the primary computer room is an input port network anomaly, a standby computer room is selected from the candidate computer rooms based on the inspection result of the standby computer room through the DNS. Specifically, the DNS selects a candidate computer room with a normal input port inspection result from the candidate computer rooms as the standby computer room to ensure that the cloud computing platform can provide external services.

[0053] The above technical solution checks the network status of the primary computer room and at least two candidate computer rooms through the DNS, can select a standby computer room when a network anomaly is detected at the input port of the primary computer room, and calls the business services deployed in the primary computer room through the standby computer room, improving the fault tolerance and stability of the cloud computing platform.

[0054] Figure 3A is a flowchart of another traffic scheduling method provided according to an embodiment of the present disclosure; this embodiment is an alternative solution proposed on the basis of the above embodiment. Specifically, the present disclosure is applicable to the case where there is a network anomaly at the output port of the primary computer room. See Figure 3A This embodiment provides a traffic scheduling method including:

[0055] S301. When there is a network anomaly at the output port of the primary computer room, obtain the processing result from the primary computer room through the data channel between the standby computer room and the primary computer room.

[0056] Among them, the output port is configured in the primary computer room. Based on the output port, the primary computer room can call the callback microservice to feedback the processing result. The processing result is obtained by the primary computer room processing the second request. Once there is a network anomaly at the output port of the primary computer room, the primary computer room cannot feedback the processing result, which affects the cloud computing platform to provide business services externally.

[0057] When there is a network anomaly at the output port of the primary computer room, the standby computer room obtains the processing result from the primary computer room through the data channel between the standby computer room and the primary computer room.

[0058] S302. Feedback the processing result through the callback microservice deployed in the standby computer room.

[0059] The callback microservice is deployed in both the standby computer room and the primary computer room. The callback microservice is used to call the user interface and feedback the processing result to the user side through the user interface. Optionally, for the primary computer room and the standby computer room that are communicatively connected based on the data channel, the callback microservice is deployed in the HA manner. Among them, HA is the abbreviation of Highly Available, which is the abbreviation of the dual-machine cluster system and is an effective solution to ensure business continuity.

[0060] When there is a network anomaly at the input interface of the primary computer room and it is impossible to call the callback microservice deployed in the primary computer room, the standby computer room obtains the processing result from the primary computer room through the data channel and feedbacks the processing result through the callback microservice deployed in the standby computer room.

[0061] When there is a network anomaly at the output port of the primary computer room in the technical solution of the present disclosure and it is impossible to feedback the processing result through the callback microservice deployed in the primary computer room, the processing result obtained from the primary computer room is feedback to the user side through the callback microservice deployed in the standby computer room, improving the availability of the business service in the cloud computing platform.

[0062] In an optional embodiment, feedbacking the processing result through the callback microservice deployed in the standby computer room includes: the processing result is also associated with a target microservice; the target microservice is selected from the candidate microservices deployed in the primary computer room; based on the association relationship between the candidate microservice and the candidate callback interface in the callback microservice, determine the target callback interface associated with the target microservice; feedback the processing result through the target callback interface.

[0063] Among them, the processing result is obtained by the primary computer room processing the access request, and the processing result needs to be fed back. The microservices are used to support the cloud computing platform to provide business services externally. Different microservices have different business functions, and the microservices can be distinguished based on the business functions. Exemplarily, Microservice 1, Microservice 2, and Microservice 3 can be used for resource management, application management, and operation and maintenance management respectively. The primary computer room determines the target microservice for processing the access request from the candidate microservices in response to the access request, and processes the access request based on the target microservice to obtain the processing result. Among them, the access request can be the first request or the second request. When there is a network anomaly at the input interface of the primary computer room, the access request is the first request; when there is no network anomaly at the input interface of the primary computer room, the access request is the second request.

[0064] The processing result is associated with the target microservice. In the embodiments of the present disclosure, the candidate callback interfaces in the callback microservice are split according to the architecture of the candidate microservices to obtain the association relationship between the candidate microservices and the candidate callback interfaces in the callback microservice. Based on the association relationship between the two, the target callback interface associated with the target microservice is determined, and the processing result is fed back through the target callback interface. Optionally, the target callback interface is called in the rpc (Remote Procedure Call) manner.

[0065] In the above technical solution, based on the association relationship between the candidate microservices and the candidate callback interfaces in the callback microservice, the target callback interface associated with the target microservice is determined, and the processing result is fed back through the target callback interface, reducing the coupling between the candidate callback interfaces in the callback microservice and improving the fault tolerance of the cloud computing platform.

[0066] Figure 3B It is a schematic structural diagram of a cloud computing platform provided according to an embodiment of the present disclosure. Refer to Figure 3B , the cloud computing platform includes a domain name system, a primary computer room, and a standby computer room. Among them, the domain name system is communicatively connected to the primary computer room and the standby computer room respectively. The domain name system is used to check the network status of the primary computer room and the standby computer room; optionally, the domain name system checks the input interfaces of the primary computer room and the standby computer room to check whether there is a network anomaly at the input interface. The domain name system is also used to distribute traffic to the primary computer room and the standby computer room. During the process of traffic distribution by the domain name system, the primary computer room has the first priority, and the standby computer room has the second priority, where the first priority is higher than the second priority. Specifically, when there is no network anomaly at the input interface of the primary computer room, the traffic is preferentially distributed to the primary computer room; when there is a network anomaly at the input interface of the primary computer room, the traffic will be distributed to the standby computer room.

[0067] When the Domain Name System detects a network anomaly at the input port of the primary computer room, it obtains the alias record of the primary computer room. Optionally, the Domain Name System includes a user domain name system, an authoritative domain name system, and a scheduling domain name system. The user domain name system, in response to an access request sent by the user terminal, obtains the alias record of the primary computer room from the authoritative domain name system. The user domain name system sends the obtained alias record belonging to the primary computer room to the scheduling domain name system. The scheduling domain name system modifies the alias record based on the standby domain name of the standby computer room to rewrite the domain name pointed to by the second request to obtain the first request. Here, the second request points to the primary domain name, and the first request points to the standby domain name. The first request is sent to the primary computer room through the standby computer room, where the primary computer room and the standby computer room are communicatively connected based on a data channel.

[0068] Exemplarily, the second request is example.com, and the second request points to 10.0.0.1. When there is no network anomaly at the input interface of the primary computer room, the user domain name system feeds back 10.0.0.1 to the user terminal; when there is a network anomaly at the input interface of the primary computer room, the user domain name system obtains the alias record of the primary computer room, such as cname.example.com, from the authoritative domain name system, and sends the obtained alias record to the scheduling domain name system. The scheduling domain name system modifies the domain name pointed to by the second request based on the alias record to obtain the first request, such that the first request points to 20.0.0.1, where 10.0.0.1 corresponds to the primary computer room and 20.0.0.1 corresponds to the standby computer room.

[0069] Business services are deployed in the primary computer room, where the business services include a scheduling service and microservices. The scheduling service is used to centrally schedule access requests and schedule the access requests to other computer rooms. Here, the access request can be the first request or the second request. Other computer rooms refer to the computer rooms in the cloud computing platform other than the primary computer room. Machine room services are deployed in other computer rooms, and long connections can be used for communication between machine room services with interaction requirements. The machine room service is used to send synchronous tasks or asynchronous tasks to the ARM devices, which execute and return or report the processing results. Generally, a large number of ARM devices are deployed in each computer room of the cloud computing platform, ranging from dozens to tens of thousands. Other computer rooms in the cloud computing platform access the primary computer room based on the internal interface (Private API) configured in the primary computer room and call the microservices deployed in the primary computer room to facilitate data interaction among the computer rooms within the cloud computing platform. Optionally, other computer rooms call the microservices deployed in the primary computer room in an http manner based on the internal interface.

[0070] The primary computer room is also configured with a public interface (Open API), enabling external users to access the primary computer room and call the microservices deployed in the primary computer room. Optionally, external users can call the microservices deployed in the primary computer room in rpc mode based on the public interface.

[0071] Optionally, there are association relationships between the microservices deployed in the primary computer room and the internal interface and the public interface respectively. Based on the above association relationships, the internal interface and the public interface can be split to obtain an internal interface group (PrivateAPI group) and a public interface group (Open API group). Before external users and / or other computer rooms call the microservices deployed in the primary computer room, the microservices deployed in the primary computer room and the corresponding internal interface group and public interface group are registered in the registration center in the primary computer room.

[0072] Optionally, callback microservices are deployed in both the primary computer room and the standby computer room, and output interfaces are configured in the primary computer room and the standby computer room. Based on the output interfaces, the callback microservices can be called to feedback the processing results. In the case of a network exception in the input interface of the primary computer room and when it is unable to call the callback microservice deployed in the primary computer room, the standby computer room obtains the processing results from the primary computer room through the data channel and feeds back the processing results through the callback microservice deployed in the standby computer room. Optionally, load balancers are also deployed in the primary computer room and the standby computer room to balance the traffic and achieve high service availability.

[0073] The service disaster recovery solutions provided by related technologies for cloud computing platforms generally include the following two types: 1. Primary and standby deployment of business services: A complete set of business services is deployed in the primary computer room and the standby computer room as primary and standby. In the case of being unable to access the business services in the primary computer room, the standby computer room is switched to provide business services. 2. Multi-active deployment of business services: Business services are scattered and deployed in multiple computer rooms, and data is synchronized between multiple computer rooms. All computer rooms can provide business services. The main disadvantages of the above two solutions are as follows: 1. Primary and standby deployment of business services: Low resource utilization rate, one set of services is in an idle state, and the domain name resolution takes a long time to take effect during the primary and standby switch; 2. Multi-active deployment of business services: The cloud computing platform is very sensitive to the device status, and the network latency caused by cross-regional data synchronization will affect the business.

[0074] In the embodiments of the present disclosure, the business service is deployed in the primary computer room. By creating a data channel between the primary computer room and the standby computer room, in the case where the business service in the primary computer room cannot be accessed, the standby computer room can access the business service in the primary computer room based on the data channel, improving resource utilization. In the embodiments of the present disclosure, the domain name pointing of the access request is modified based on the alias record to achieve primary-standby switching, shortening the effective duration of domain name resolution. The embodiments of the present disclosure support deploying only one set of business services in the cloud computing platform, and the cost required for the solution provided by the present disclosure is only 20% of the primary-standby deployment solution for business services in the related art. The embodiments of the present disclosure effectively reduce the service disaster recovery cost.

[0075] Figure 4 It is a schematic structural diagram of a traffic scheduling device provided according to an embodiment of the present disclosure. The embodiments of the present disclosure are applicable to the situation where there is a network anomaly at the input port of the primary computer room. The device can be implemented by software and / or hardware, and the device can implement the traffic scheduling method described in any embodiment of the present disclosure.

[0077] A request sending module 402, configured to send the first request to the primary computer room through the data channel between the standby computer room and the primary computer room, and the primary computer room processes the first request to obtain a processing result.

[0078] The embodiments of the present disclosure provide a service disaster recovery solution. By setting a data channel between the standby computer room and the primary computer room, in the case where there is a network anomaly at the input port of the primary computer room, the standby computer room can, through the data channel, obtain a first request to be processed from the domain name system and send the first request to the primary computer room, and the primary computer room processes the first request to obtain a processing result, improving the availability of the business service in the cloud computing platform. The technical solution provided by the embodiments of the present disclosure supports deploying the business service only in the primary computer room, which is beneficial to reducing the disaster recovery cost of the cloud computing platform.

[0079] Optionally, the data channel is obtained by creating a peer connection between the primary computer room and the standby computer room.

[0080] Optionally, the device further includes: a result acquisition module, configured to obtain the processing result from the primary computer room through the data channel between the standby computer room and the primary computer room when there is a network anomaly at the output port of the primary computer room; and a result feedback module, configured to feedback the processing result through the callback microservice deployed in the standby computer room.
