[0002] With the development of data processing technology, when updating services, it is usually necessary to switch service clusters.

[0060] 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.

[0061] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations. The acquisition, storage, use, and processing of data in the technical solution of this application are in compliance with relevant provisions of national laws and regulations.

[0062] The application service cluster switching method of the present application is applied to an application service system, which includes a first service component, an intermediate component, a second service component, a first service cluster and a second service cluster, wherein the first service component is used to register a cluster server of the first service cluster, the intermediate component is used to register a cluster server of the first service cluster and a cluster server of the second service cluster, and the second service component is used to register a cluster server of the second service cluster.

[0063] Based on this, it can be seen that when the first service component is an online component, since the cluster server of the first service cluster is registered on the first service component, the application service traffic obtained by the online component will all be directed to the cluster servers of the first service cluster; when the intermediate component is an online component, since the cluster servers of the first service cluster and the cluster servers of the second service cluster are registered on the intermediate component at the same time, the application service traffic obtained by the online component will be directed to the cluster servers of the first service cluster and the cluster servers of the second service cluster; when the second service component is an online component, since the cluster servers of the second service cluster are registered on the second service component, the application service traffic obtained by the online component will be directed to the cluster servers of the second service cluster.

[0064] In an exemplary embodiment, Figure 1 As shown, a method for switching an application service cluster is provided, and the method includes the following steps 202 to 204. Among them:

[0065] Step 202, traffic diversion step: switch the online component from the first service component to the intermediate component; obtain application service traffic through the online component, and divide the application service traffic into a first part of traffic and a second part of traffic; divert the first part of traffic to the first service cluster through the intermediate component, and divert the second part of traffic to the second service cluster, and execute the application service response process corresponding to the application service traffic.

[0066] Among them, the first service component, the intermediate component and the second service component can all be set in the service directory, and the online component can be switched among the first service component, the intermediate component and the second service component in the service directory; the first service component registers the server address of each cluster server in the first service cluster, the intermediate component simultaneously registers the server address of each cluster server in the first service cluster and the server address of each cluster server in the second service cluster, and the second service component registers the server address of each cluster server in the second service cluster.

[0067] As an example, the number of the first service component and the second service component may be one, and the number of the intermediate components may be one or more.

[0068] As an example, step 202 includes: switching the online component from the first service component to the intermediate component in the service catalog, obtaining application service traffic through the intermediate component, and dividing the application service traffic into a first part of traffic and a second part of traffic according to a preset traffic ratio; diverting the first part of traffic to the first service cluster through the server address of the cluster server of the first service cluster registered on the intermediate component, and diverting the second part of traffic to the second service cluster through the server address of the cluster server of the second service cluster registered on the intermediate component; executing the application service response process corresponding to the first part of traffic through the first service cluster, and executing the application service response process corresponding to the second part of traffic through the second service cluster.

[0069] It should be noted that the application service response process is used to process the application service traffic and output the corresponding response result. For example, assuming that the application service traffic is user portrait information, the response result may be a user classification result based on the user portrait information.

[0070] In some embodiments, the proportion of the second part of the traffic in the application service traffic is less than a preset traffic proportion threshold, which can ensure that the intermediate component will first divert a small amount of application service traffic to the second service cluster to execute the application service response process. In this way, since the application service traffic diverted to the second service cluster is small, but the application service traffic diverted to the first service cluster is large, even if the application service response process of the second service cluster executes abnormally, it will not have a significant impact on the entire application service, thereby causing the overall collapse of the application service.

[0071] Step 204: If the application service response process is executed without exception, the online application service cluster is switched from the first service cluster to the second service cluster by switching the online component from the intermediate component to the second service component.

[0072] As an example, step 204 includes: if the application service response processes of the first service cluster and the second service cluster are executed without exception, the online component is switched from the intermediate component to the second service component, so that the second service component obtains the application service traffic and diverts the obtained application service traffic to the second service cluster according to the server address of the cluster server of the registered second service cluster, thereby switching the online application service cluster from the first service cluster to the second service cluster.

[0073] It should be noted that the intermediate component can register all cluster servers in the first service cluster and all cluster servers in the second service cluster; the intermediate component can also register all cluster servers in the first service cluster and some cluster servers in the second service cluster. The specific settings can be flexibly set according to actual needs.

[0074] In some embodiments, dividing the application service traffic into a first portion of traffic and a second portion of traffic includes:

[0075] Obtain a first server address of a first service cluster and a second server address of a second service cluster; allocate a first server address and a second server address to application service traffic according to preset traffic weight information; determine the application service traffic allocated with the first server address as a first part of traffic, and determine the application service traffic allocated with the second server address as a second part of traffic.

[0076] Among them, the preset traffic weight information is used to determine the proportion of traffic diverted to the first service cluster and the second service cluster. For example, assuming the preset traffic weight information is 0.1, it means that 10% of the application service traffic is diverted to the first service cluster, and the remaining 90% of the application service traffic is diverted to the second service cluster.

[0077] Specifically, the first server address of the cluster server in the first service cluster and the second server address of the cluster server in the second service cluster are obtained; according to the preset traffic weight information, the first server address is allocated to a part of the application service traffic to obtain the first part of the traffic, and the second server address is allocated to another part of the application service traffic to obtain the second part of the traffic. In this way, the first part of the traffic will be automatically addressed to the first server cluster according to the first server address, that is, the first part of the traffic will be automatically diverted to the first server cluster, and the second part of the traffic will be automatically addressed to the second server cluster according to the second server address, that is, the second part of the traffic will be automatically diverted to the second service cluster.

[0078] In the above-mentioned application service cluster switching method, the application service system is provided with a first service component, an intermediate component, a second service component, a first service cluster and a second service cluster. The first service component is used to register the cluster server of the first service cluster, the intermediate component is used to register the cluster server of the first service cluster and the cluster server of the second service cluster, and the second service component is used to register the cluster server of the second service cluster. In this way, when the application service is switched in the application service system, the online component will be switched from the first service component to the intermediate component first, so that after the intermediate component obtains the application service traffic, the application service traffic will be divided into a first part of the traffic and a second part of the traffic, and the first part of the traffic will be diverted to the first service cluster, and the second part of the traffic will be diverted to the second service cluster to execute the application service process corresponding to the application service traffic. In this way, even if the application service response process is executed abnormally in the second service cluster, the first part of the traffic still exists in the first service cluster, and the entire application service will not crash. When the application service response process is executed normally, by switching the online component from the intermediate component to the second service component, the online application service cluster is switched from the first service cluster to the second service cluster, and the service cluster switching can be completed smoothly, so the system stability during the service cluster switching can be improved.

[0079] In an exemplary embodiment, Figure 3 As shown, the application service response process includes a first-stage response process and a second-stage response process; the intermediate component includes a first intermediate component and a second intermediate component; and the traffic diversion step includes:

[0080] Step 302: Switch the online component from the first service component to the first intermediate component.

[0081] Among them, the online component refers to the component of the application service system that is currently in operation. The online component can obtain application service traffic and divert the application service traffic to the cluster server.

[0082] Step 304, divides the application service traffic obtained by the first intermediate component into a first part of traffic and a second part of traffic, and diverts the first part of traffic to the first service cluster through the first intermediate component, and diverts the second part of traffic to the second service cluster, and executes the first stage response process of the application service traffic.

[0083] The intermediate component may include a first intermediate component and a second intermediate component, and the application service response process may include a first-stage response process and a second-stage response process.

[0084] As an example, step 304 includes: according to a first preset traffic diversion ratio, dividing the acquired application service traffic into a first part of traffic and a second part of traffic through a first intermediate component, and diverting the first part of traffic to a first service cluster, and diverting the second part of traffic to a second service cluster; executing a first-stage response process corresponding to the first part of traffic through the first service cluster, and executing a first-stage response process corresponding to the second part of traffic through the second service cluster.

[0085] Step 306: If the first-stage response process is executed without exception, the online component is switched from the first intermediate component to the second intermediate component, and the application service traffic is divided into the third part of traffic and the fourth part of traffic through the second intermediate component.

[0086] Step 308: Divert the third portion of traffic to the first service cluster through the second intermediate component, and divert the fourth portion of traffic to the second service cluster, and execute the second phase response process of the application service traffic.

[0087] As an example, steps 306 to 308 include: if the first-stage response process is executed without abnormalities, the online component is switched from the first intermediate component to the second intermediate component, and the obtained application service traffic is divided into a third part of the traffic and a fourth part of the traffic according to a second preset traffic diversion ratio; the third part of the traffic is diverted to the first service cluster, and the fourth part of the traffic is diverted to the second service cluster; the second-stage response process corresponding to the third part of the traffic is executed through the first service cluster, and the second-stage response process corresponding to the fourth part of the traffic is executed through the second service cluster.

[0088] Furthermore, if the second-stage response process is executed without exception, the online component is switched from the second intermediate component to the second service component.

[0089] It should be noted that the proportion of the fourth part of traffic in the application service traffic is greater than the proportion of the second part of traffic in the application service traffic; the proportion of the third part of traffic in the application service traffic is less than the proportion of the first part of traffic in the application service traffic.

[0090] In some embodiments, the above-mentioned application service cluster switching method further includes:

[0091] If the first-stage response process executes abnormally, the cluster server where the second service cluster is registered with the first intermediate component will be suspended or deregistered; if the second-stage response process executes abnormally, the online component will be switched from the second intermediate component to the first service component.

[0092] Among them, during the execution of the first stage response process, the traffic proportion of the second part of the application service traffic diverted to the second service cluster is less than the first preset traffic proportion; during the execution of the second stage response process, the traffic proportion of the fourth part of the application service traffic diverted to the second service cluster is greater than the second preset traffic proportion, and the second preset traffic proportion is greater than the first preset traffic proportion.

[0093] Specifically, in the case of abnormal execution of the first-stage response process, the second service cluster can be suspended or deregistered from the cluster server of the first intermediate component. Since the proportion of the second part of the application service traffic diverted to the second service cluster is smaller than the first preset traffic proportion, suspending or deregistering the second service cluster from the cluster server of the first intermediate component will basically not affect the operation of the entire application service, and the problem of abnormal execution of the application service response process can also be quickly resolved.

[0094] In the event of an abnormal execution of the second-stage response process, the online component can be switched from the second intermediate component to the first service component to implement version update rollback of the application service system. That is, since the proportion of the fourth part of the application service traffic diverted to the second service cluster is greater than the second preset traffic proportion, the traffic diverted to the second service cluster is relatively large at this time. In order to ensure the stability and security of the entire application service, all application service traffic needs to be re-diverted to the first service cluster to implement version rollback of the application service update.

[0095] In this embodiment, a first intermediate component and a second intermediate component are provided. Since the first intermediate component can divide the obtained application service traffic into a first part of traffic and a second part of traffic, and divert the first part of traffic to the first service cluster, and divert the second part of traffic to the second service cluster, the second intermediate component can switch the obtained application service traffic into a third part of traffic and a fourth part of traffic, and divert the third part of traffic to the first service cluster, and divert the fourth part of traffic to the second service cluster. Since the traffic proportion of the fourth part of traffic in the application service traffic is greater than the traffic proportion of the second part of traffic in the application service traffic; the traffic proportion of the third part of traffic in the application service traffic is less than the traffic proportion of the first part of traffic in the application service traffic, the application service traffic is gradually switched from the first service cluster to the second service cluster in two stages. Compared with the method of directly switching all traffic from the first service cluster to the second service cluster, even if an abnormality occurs in the execution of the application service process, the entire application service will not crash, thereby improving the system stability when the application service cluster is switched.

[0096] In some embodiments, reference Figure 3The application service response process includes multiple stage response processes, and the intermediate components include multiple stage intermediate components; the traffic diversion steps include:

[0097] Step 402, component switching step: switching the online component to the intermediate component of the stage.

[0098] Step 404, stage traffic diversion step: according to the preset traffic weight information corresponding to the stage intermediate component, the application service traffic obtained by the stage intermediate component is divided into a first part of traffic and a second part of traffic, and the first part of traffic is diverted to the first service cluster, and the second part of traffic is diverted to the second service cluster, and the stage response process of the application service traffic is executed.

[0099] Step 406, if the stage response process is executed without exception, return to the execution component switching step until the multiple stage response processes are all executed or any stage response process is executed abnormally.

[0100] Among them, the intermediate component may include multiple stage intermediate components, and each stage intermediate component will simultaneously divert the acquired application service traffic to the first service cluster and the second service cluster to execute the corresponding stage response process.

[0101] As an example, steps 402 to 406 include: a component switching step: switching the online component to a stage intermediate component; a stage traffic diversion step: according to the preset traffic weight information corresponding to the stage intermediate component, the application service traffic obtained by the stage intermediate component is divided into a first part of the traffic and a second part of the traffic, and the first part of the traffic is diverted to the first service cluster, and the second part of the traffic is diverted to the second service cluster, the stage response process corresponding to the first part of the traffic is executed through the first service cluster, and the stage response process corresponding to the second part of the traffic is executed through the second service cluster; if the stage response process is executed without exception, return to execute the above-mentioned component switching step until multiple stage response processes are executed or any stage response process is executed abnormally.

[0102] It should be noted that if the response process is executed abnormally at any stage, the online component will be switched to the first service component to perform version rollback of the application service to ensure the stability of the application service.

[0103] When the stage traffic diversion step is executed for the Nth time, the proportion of the second part of the traffic in the application service traffic is greater than the proportion of the second part of the traffic in the application service traffic when the stage traffic diversion step is executed for the N-1th time; when the stage traffic diversion step is executed for the first time, the online component is switched from the first service component to the stage intermediate component, and when the stage traffic diversion step is executed from the second to the Nth time, the online component switches between the intermediate components of each stage, and N is a positive integer greater than 1.

[0104] In this embodiment, multiple stage intermediate components are set between the first service component and the second service component, and starting from the first service component, the online components are gradually switched between the intermediate components of each stage, so that the proportion of traffic diverted to the second service cluster gradually increases, and each stage intermediate component will detect whether the corresponding stage response process is executed without exception when diverting traffic to the first service cluster and the second service cluster, thereby realizing multi-stage gradual switching of application service clusters, gradually migrating the traffic of the first service cluster to the second service cluster, and finally completing the switching of the application service clusters. Compared with the method of directly switching all traffic from the first service cluster to the second service cluster, even if the application service process execution is abnormal, it will not cause the entire application service to crash, so the system stability during the application service cluster switching can be improved.

[0105] In a complete embodiment, the application service system includes a first service component, an intermediate component, a second service component, a first service cluster and a second service cluster, the first service component is used to register the cluster server of the first service cluster, the intermediate component is used to register the cluster server of the first service cluster and the cluster server of the second service cluster, and the second service component is used to register the cluster server of the second service cluster.

[0106] Based on the above application service system, the application service response process includes a first-stage response process and a second-stage response process; the intermediate component includes a first intermediate component and a second intermediate component; the application service system first switches the online component from the first service component to the first intermediate component; according to the first preset traffic diversion ratio, the obtained application service traffic is divided into a first part of traffic and a second part of traffic through the first intermediate component, and the first part of traffic is diverted to the first service cluster, and the second part of traffic is diverted to the second service cluster; the first-stage response process corresponding to the first part of traffic is executed through the first service cluster, and the first-stage response process corresponding to the second part of traffic is executed through the second service cluster; if the first-stage response process is executed without abnormality, the online component is switched from the first intermediate component to the second intermediate component, and according to the second preset traffic diversion ratio, the obtained application service traffic is divided into a third part of traffic and a fourth part of traffic; the third part of traffic is diverted to the first service cluster, and the fourth part of traffic is diverted to the second service cluster; the second-stage response process corresponding to the third part of traffic is executed through the first service cluster, and the second-stage response process corresponding to the fourth part of traffic is executed through the second service cluster.

[0107] Among them, the proportion of the fourth part of traffic in the application service traffic is greater than the proportion of the second part of traffic in the application service traffic; the proportion of the third part of traffic in the application service traffic is less than the proportion of the first part of traffic in the application service traffic.

[0108] Furthermore, if the second-stage response process is executed without exception, the online component will be switched from the intermediate component to the second service component, so that the second service component will obtain application service traffic and divert all the obtained application service traffic to the second service cluster according to the server address of the cluster server of the registered second service cluster, thereby switching the online application service cluster from the first service cluster to the second service cluster.

[0109] Furthermore, in the event of an abnormal execution of the first-stage response process, the second service cluster can be suspended or deregistered from the cluster server of the first intermediate component. Since the proportion of the second part of the application service traffic diverted to the second service cluster is less than the first preset traffic proportion, suspending or deregistering the second service cluster from the cluster server of the first intermediate component will basically not affect the operation of the entire application service, and the problem of abnormal execution of the application service response process can also be quickly resolved.

[0110] In this embodiment, the application service traffic is gradually switched from the first service cluster to the second service cluster in two stages. Compared with the method of directly switching all traffic from the first service cluster to the second service cluster, even if an abnormality occurs in the execution of the application service process, it will not cause the entire application service to crash. Therefore, the system stability during the application service cluster switching can be improved.
