Cloud services (cloud services) are an augmentation, usage, and interaction model of internet-based related services that typically involve providing dynamically extensible and often virtualized resources over the internet. Cloud is a metaphor of network and internet. Cloud services generally refer to obtaining desired services over a network in an on-demand, easily extensible manner. Such services may be IT and software, internet related, or other services.
Cloud storage (cloud storage) is a mode of online storage, i.e., data is stored on multiple virtual servers, usually hosted by third parties, rather than on dedicated servers. The concept of cloud storage is similar to cloud computing. Cloud computing (cloud computing) refers to a technology architecture that accesses a flexibly extensible shared physical or virtual resource pool through a network, where the resources may include servers, operating systems, networks, software, applications, storage devices, and the like, and may be deployed and managed in an on-demand, self-service manner. Through the cloud computing technology, high-efficiency and strong data processing capacity can be provided for technical application and model training of artificial intelligence, block chains and the like.
The embodiment of the application can be applied to an internet large-scale distributed system, and the applicable scene is that the request is accessed interface by interface according to a certain proportion before the new service module configured by reconstruction upgrading or migration platform is formally used, so that the problem of the new service module can be timely found out, and the loss caused by service migration or upgrading and the like can be reduced as much as possible.
Referring to fig. 1, fig. 1 is a flowchart of a service control method provided by an embodiment of the present disclosure, and the method is applied to an electronic device, such as a base layer between an upstream service module and a downstream service module, for forwarding a request issued by the upstream service module to the downstream service module. As shown in fig. 1, the method comprises the steps of:
step 11: and acquiring a request initiated by the upstream service module to the downstream service module.
In this embodiment, the request may be a scheduling request, for example, a Remote Procedure Call (RPC) request. The upstream service module and the downstream service module may be service modules in a Remote Dictionary service (Redis) based distributed system.
Step 12: and judging whether the prestored flow discharge information comprises target flow discharge information matched with the downstream service module.
It should be noted that, in the embodiment of the present application, the downstream service module may correspond to the original service module and the new service module. The new service module is a service module obtained on the basis of the original service module due to service migration or upgrading and the like. For example, assuming that the original service module has 10 interfaces, when one or more of the 10 interfaces is upgraded or migrated to the platform, the one or more interfaces constitute a new service module, but the original service module remains unchanged.
The pre-stored traffic volume information may be used to indicate whether to send a request of a corresponding downstream service module to a new service module corresponding to the downstream service module, so as to implement lossless migration or upgrade of a service.
Step 13: and when the prestored flow play information comprises target flow play information matched with the downstream service module, judging whether the target flow play information comprises the requested downstream interface information.
Understandably, when the target traffic volume information includes information of a downstream interface corresponding to the request, the target traffic volume information may indicate that the request is sent to a new service module corresponding to the downstream service module. Otherwise, when the target traffic volume information does not include the information of the downstream interface corresponding to the request, the request is sent to the original service module corresponding to the downstream service module, that is, normal request sending is executed.
In one embodiment, the information of the downstream interface may include, but is not limited to, an identifier of the downstream interface, a scaling value of the downstream interface, and the like.
Step 14: and when the target flow discharge information comprises the requested information of the downstream interface, sending the request to a new service module corresponding to the downstream service module.
In this embodiment of the application, after a request initiated by an upstream service module to a downstream service module is obtained, it may be determined whether pre-stored traffic volume information includes target traffic volume information matched with the downstream service module, and when the pre-stored traffic volume information includes the target traffic volume information matched with the downstream service module, it may be determined whether the target traffic volume information includes information of a requested downstream interface, and when the target traffic volume information includes the information of the requested downstream interface, the request may be sent to a new service module corresponding to the downstream service module. Therefore, under the scene of realizing the interface-by-interface access request of the new service module, the interface-by-interface access request of the new service module can be realized based on the prestored flow discharge information, so that the interface-by-interface access request of the new service module is realized without modifying the code logic of the upstream service module, and the maintenance cost is reduced; furthermore, unnecessary online modification of the upstream service module caused by upgrading or transferring the downstream service module can be effectively reduced, and risks caused by online configuration are reduced.
Furthermore, for the upstream service module, the scheme in the application only needs to rely on the electronic equipment between the upstream service module and the downstream service module, such as a basic layer, the change cost is almost 0, the control of the release logic is almost insensitive to the upstream service module, the release proportion of the interface is adjusted only by modifying the flow release information, the upstream service module does not need to be re-on-line and the like, and therefore resources such as a server and the like are saved.
Optionally, after performing step 11 and before performing step 12, the electronic device may determine whether the downstream service module currently enables the low-traffic policy. The low-traffic policy can be understood as interface-by-interface access to a new service module corresponding to the configured downstream service module. If the small-flow strategy is not started currently, the access is normally carried out, namely the request is directly sent to the downstream service module. If the low-traffic policy is currently enabled, step 12 is further performed.
Optionally, as shown in fig. 1, the service control method in this embodiment further includes the following steps:
step 15: when the prestored flow release information does not include target flow release information matched with the downstream service module, sending a request initiated to the downstream service module to an original service module corresponding to the downstream service module; or, when the pre-stored traffic volume information includes target traffic volume information matched with the downstream service module but the target traffic volume information does not include information of a downstream interface of the request initiated by the downstream service module, sending the request to the original service module corresponding to the downstream service module. In this way, requests by upstream service modules to downstream service modules can be guaranteed to be executed.
In this embodiment of the application, in order to implement an interface-by-interface access request of a new service module, a server for controlling a small traffic volume proportion, such as a redis-based server, may be deployed, and store corresponding traffic volume information in the server, and the electronic device periodically accesses the server to obtain pre-stored traffic volume information from the server. The above-mentioned small flow rate play-out ratio may be understood as a partial request play-out ratio.
Optionally, the service control method in this embodiment may further include: and acquiring prestored flow discharge information from the server. For example, pre-stored traffic volume information may be pulled from the server periodically. Therefore, by means of the deployment server, when the interface release proportion is changed or a module interface is newly added, only corresponding flow release information needs to be added or modified in the server, and an upstream service module or a current service module does not need to be changed and re-on-line, so that the maintenance cost is reduced; and the flow volume information pulled from the server can be stored in the memory, the processing speed is high, and excessive time consumption is not increased.
In one embodiment, the format of the traffic volume information in this embodiment may be: < service name: [ interface identification: ratio value ], [ interface identification: ratio value ], … >. The service name is the identifier of the downstream service module matched with the flow discharge information, and is used for indicating the downstream service module matched with the flow discharge information. The proportional value can be understood as a flow scaling value of the interface corresponding to the corresponding interface identifier. The interface identifier and the ratio value are used to indicate which interface or interfaces of the corresponding downstream service module request to send to the new service module with a certain ratio value.
Optionally, when the information of the downstream interface includes the play scale value, the sending the request to the new service module corresponding to the downstream service module may include: judging whether the release proportion value is larger than a randomly generated proportion value or not; and when the release proportion value is larger than the randomly generated proportion value, sending the request to a new service module corresponding to the downstream service module. And if the release quantity proportional value is smaller than or equal to the randomly generated proportional value, sending the request to the original service module corresponding to the downstream service module. In this way, by comparing the proportional value with the randomly generated proportional value, the proportional value in the traffic information can be controlled, and the traffic information can be modified in an auxiliary manner when the service is upgraded or migrated.
The method for randomly generating the ratio value may be a linear congruence method, and the formula is (a × RandSeed + B)% M. Where A is a multiplier, B is an increment, M is a modulus, A, B and M are both constants. An initial value (RandSeed) is selected and then the next random number is calculated. Typically the initial value is chosen to be the current timestamp so that the value is generated each time it is not dependent on the value previously generated.
For example, referring to fig. 2, the service control procedure in this embodiment may include:
s1: the basic library periodically pulls prestored flow discharge information from the server;
s2: the method comprises the steps that a basic library acquires an RPC request initiated by an upstream service module to a downstream service module;
s3: and the basic library judges whether the prestored flow discharge information comprises target flow discharge information matched with the downstream service module.
S4: and if the target flow discharge information is not included, the RPC request is sent to an original service module corresponding to the downstream service module.
S5: and if the target flow release information is judged to be included, judging whether the target flow release information includes the requested information of the downstream interface.
S6: further, if the information of the downstream interface not including the request is judged, the RPC request is sent to the original service module corresponding to the downstream service module.
S7: and if the information of the corresponding downstream interface is judged to be included, the RPC request is sent to a new service module corresponding to the downstream service module.

Optionally, the sending module 34 is further configured to:
when the pre-stored flow discharge information does not comprise target flow discharge information matched with the downstream service module, sending the request to an original service module corresponding to the downstream service module;
or, when the pre-stored traffic volume information includes target traffic volume information matched with the downstream service module but the target traffic volume information does not include information of the downstream interface of the request, sending the request to an original service module corresponding to the downstream service module.
