Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
First, explanation is made on terms involved in the present application:
microservice architecture (Micro service Architecture): is an architectural concept aimed at decoupling solutions by breaking down functionality into discrete services.
The micro-service architecture is characterized by comprising the following components:
1) And (5) independent deployment and flexible expansion are realized. Conventional monolithic architecture is deployed in units of an entire system, while micro services are deployed in units of each individual component (e.g., user service, commodity service).
2) Efficient isolation of resources. One of the principles of microservices design is that each microservice has an independent data source, and if microservice a wants to read and write a database of microservice B, only an interface exposed by microservice B can be called to complete. Thus, the problems caused by contending the database and caching resources among the micro services are effectively avoided.
In the service layer 100 of the e-commerce system as shown in fig. 1, in order to meet the demands of the mobile internet for large projects and multiple clients, the service layer 100 is divided into a user management service 110, a single sign-on service 120, a commodity service 130, a logistics service 140, a content management system (Content Management System, CMS) service 150 and an order service 160. The user management service 110 manages information of all users registered on the e-commerce system; the single sign-on service 120 provides a sign-on authentication service; the commodity service 130 manages the states and attributes of all commodities in the electronic commerce system; the logistics service 140 manages the state of logistics corresponding to the order in the e-commerce system; the CMS service 150 is used to build a variety of pages; the order service 160 manages the order type and order status in the e-commerce system, and collects a series of order real-time data about goods, offers, users, receiving information, payment information, and the like.
Each split service only completes a specific business function, for example, the order service only realizes the business related to the order, the user service realizes the business related to the user management, and the like, and the granularity of the service is small, so the split service is called as a micro-service architecture.
FIG. 2 illustrates a schematic diagram of an implementation environment provided by an exemplary embodiment of the present application, the application platform 210 is a micro-service architecture that includes one or more micro-services: (four micro services are shown in FIG. 2 as examples) micro service 211, micro service 212, micro service 213, micro service 214.
The application platform 210 further includes a control module 215 for adjusting the micro-service application on the application platform 210, such as limiting the current, fusing, or degrading a micro-service application, so as to prevent the application platform 210 from crashing due to the processing capability being unable to withstand.
For a service request from a user, in order to implement the overall functionality corresponding to the service request, application platform 210 invokes one or more of micro service 211, micro service 212, micro service 213, micro service 214 to process the service request. There is a call relationship between micro service 211, micro service 212, micro service 213, micro service 214, directed edges from the requesting party of the service to the provider of the service. The control module 215 employs tuning operations to control and manage the individual micro-services.
In a specific implementation, the plurality of micro-services implement their functions through a single server or a server cluster, and the control module implements their functions through a control server. The servers are connected through a wireless network or a wired network.
It should be further noted that the term "micro-service" in the present application is a relative concept, sometimes also referred to as simply "service" in the embodiments of the present application.
Fig. 3 shows a flowchart of a service adjustment method according to an exemplary embodiment of the present application, which is applied to a control server, and the method includes the following steps:
step 301, determining a first service;
wherein the first service is a service whose service performance does not meet the service requirement.
Alternatively, service performance refers to the ability of a service to perform data processing. Service performance may refer to: a success rate of service processing target request data; and may also refer to: a response time length of service processing target request data; it may also be referred to as: and a service processes the combined result of the success rate and the response time of the target request data. The target request data refers to data sent to the service request processing by other services. The traffic demand may be a threshold determined according to the nature of the different traffic, the traffic demand being related to the nature of the traffic.
By way of example, service performance refers to a success rate of service processing target request data, with a threshold of 0.9. The control server monitors the success rate of each service processing target request data. When the success rate of processing the target request data by the service A is lower than the threshold value of the service requirement by 0.9, the control server determines the service A as the first service.
Step 302, obtaining the i-th importance of the i-th second service in the N second services;
the second service is a service calling the first service, and N second services calling the first service exist in the micro service architecture, wherein N is a positive integer.
Illustratively, in the application platform shown in fig. 2, the first service is a micro-service application 214, and the second service is a micro-service application 212 that invokes the service.
Optionally, after determining the first service, the control server determines a service that invokes the first service as the second service according to a calling relationship between the services. The present application does not limit the number N of second services.
Alternatively, for the first service and the second service, the first service is a "superior micro-service" of the second service, i.e. in case the first service is relied upon by the second service, the relied first service is a superior micro-service. The second service is a "lower level micro-service" of the first service, i.e. in case the second service works in dependence of the first service, the second service that needs to rely on the first service is a lower level micro-service.
Illustratively, N is 1. The first service is service a, there are 1 service that invokes the service: service b. Service b is a second service.
Illustratively, N is 3. The first service is service a, there are 3 services that call this service: service c, service d, service e. Service c, service d, service e is the second service.
It should be noted that, when N is 0, that is, there is no service to call the first service, no adjustment operation is required for other services.
Step 303, judging whether i is equal to N;
when i is not equal to N, step 302 is performed again after i is incremented. When i is equal to N, step 304 is performed.
The control server may be executed simultaneously when determining the 1 st to i th importance, and the order of determining the 1 st to i th importance is not limited in this application.
Step 304, according to the obtained 1 st to N th importance, adjusting T second services in N second services;
wherein T is a positive integer not greater than N.
The second service is adjusted to improve the service performance of the first service from less than the threshold to greater than the threshold. Optionally, the value of T is determined by the control server according to the restoration condition of the service performance of the first service, and T may be 1 or more.
The adjustment operation of the T second services by the control server may be performed sequentially in a certain order, or may be performed once.
Wherein the ith importance is according to M i The importance of a third service, M, which is the service that invokes the ith second service i Is a positive integer.
Wherein the third service is a service calling the ith second service, M i Is a positive integer.
Illustratively, N is 3, i.e., there are 3 second services invoking the first service: the service 1 is provided with a service profile,service 2 and service 3. The control server determines M to invoke service 1 1 And the third service, acquiring their importance to determine the 1 st importance of service 1. Next, the control server determines M to invoke service 2 2 And the third service, acquires their importance to determine the 2 nd importance of service 2. Finally, the control server determines the M of the calling service 3 3 And a third service, acquiring their importance to determine the 3 rd importance of service 3.
The "ith" in the ith importance indicates that the ith importance corresponds to the ith second service importance, not the order of the importance of the ith second service.
Illustratively, in the application platform shown in fig. 2, the first service is a micro service 214, the second service is a micro service 212 that invokes the service, and the third service is a micro service 211 that invokes the micro service 212.
Optionally, after determining a second service (i.e. the ith second service), the control server determines, according to the call relationship between the services, the service that calls the second service as a third service, where the number of the third services is M i M is the same as i Is a positive integer.
Alternatively, for the second service and the third service, the second service is an "upper micro service" of the third service, i.e. in case the second service is relied upon by the third service, the relied second service is an upper micro service. The third service is a "lower level micro-service" of the second service, i.e. in case the third service works in dependence of the second service, the second service that needs to rely on the first service is a lower level micro-service.
Each service corresponds to an importance, and the control server adjusts the services in the micro-service architecture according to the importance of the services. The server needs to acquire M invoking the ith second service when determining the ith importance of the ith second service i The importance of the third service can be obtained.
The importance of the third service is also related to the service that calls the third service, so that the determination of the i-th importance of the i-th second service comprehensively considers the call relationship between the services under the overall function.
In summary, in the method provided in this embodiment, when the second service to be adjusted is determined according to the importance, the importance of the second service is more comprehensively and comprehensively determined from the perspective of the overall function by combining the importance of the third service calling the second service, so as to avoid the problem that the importance of one service is not accurate enough when the importance of the second service is determined only by a single parameter.
In an alternative embodiment based on fig. 3, fig. 4 shows a flowchart of a service adjustment method according to an exemplary embodiment of the present application, which is applied to a control server. In this embodiment, before determining the first service, steps 305 and 306 are further included:
step 305, obtain the ith 1 Importance and ith 2 Importance of the material;
wherein the ith 1 Importance is the own importance of the ith second service, the ith 2 Importance is M i Importance of the third service to the ith second service.
In an alternative example, step 305 may alternatively be implemented as step 3051, step 3052, step 3053, and step 3054:
Step 3051, obtaining a first weight coefficient of an ith second service;
wherein the first weight coefficient represents a weight of the initial importance of the ith second service to the ith importance.
Initial importance is the importance of one service to the overall functionality when the individual services are split independently. Optionally, the initial importance may be determined by the server according to one or more of service parameters such as nature of service, number of requests of service, etc., or may be manually set.
Illustratively, the e-commerce system splits the service of purchasing goods by a user into a goods inventory service, a goods detail service, a payment service, a user points service, an order service, and the like. The control server sets an initial importance for each service according to the nature of each service. Since the goods inventory service, the payment service, and the order service are the services of the comparison core among the services for purchasing goods, the control server sets the initial importance of the goods inventory service, the goods detail service, the payment service, the user point service, the order service as: 2. 1, 2, 1, 2.
Optionally, the initial weight coefficient for each service is the same for its final importance, all being the first weight coefficient.
Illustratively, the first weight coefficient is 0.6, i.e. the initial importance of the ith second service is weighted for the ith importance by 0.6.
Optionally, the control server determines the second service by: acquiring a directed acyclic network of a service; determining a service call relationship according to the directed acyclic network; and determining N second services according to the service calling relation.
The directed acyclic network of services is a network that presents call relationships between services in an intuitive schematic way. Wherein a node in the network corresponds to a service. The directed edges existing between the nodes represent that call relationships exist between the corresponding services, and the directed edges point from the requesting party of the services to the provider of the services.
The control server, after acquiring the directed acyclic network of the service, finds the node corresponding to the first service, determines which nodes corresponding to the service are directed to the node of the first service, and determines the service as the second service, where the number of the second services is N.
It should be noted that, the service directed acyclic network is updated immediately, that is, when a new service is added or an existing service is withdrawn from the network, the service directed acyclic network changes correspondingly, so as to indicate the updated service call relationship.
Step 3052, determining the ith according to the product of the first weight coefficient and the initial importance 1 Importance of the material;
ith (i) 1 Importance is related to the first weight coefficient and the initial importance, ith 1 The relationship of importance to the first weight coefficient is a positive correlation.
Step 3053, subtracting the first weight coefficient from the target value to obtain a second weight coefficient;
wherein the second weight coefficient is M i The importance of the third service is for the weight of the ith importance, the target value being a positive number greater than the first weight coefficient.
Alternatively, the target value is 1. Illustratively, the first weight coefficient is 0.8 and the second weight coefficient is 0.2. In this case, the impact ratio of the initial importance of the ith second service on the ith importance is shown to be 80%, and the ratio of the ratio is a value obtained by dividing the first weight coefficient by the target value; indicating M i The impact of the importance of the third service on the ith importance is 20% and the ratio of the duty cycle is the value of the second weight coefficient divided by the target value.
Step 3054, according to the second weight coefficient and M i The product sum of the importance of the third service, determining the ith 2 Importance.
Ith (i) 2 Importance and first weight coefficient and M i The importance of the third service is related to the ith 2 The relationship of importance to the first weight coefficient is a negative correlation.
Alternatively, the importance of the third service may be the importance of the service updated in real time, or may be uniformly represented by a numerical value.
Illustratively, after each time a third service is acquired by the control server, the importance of the third service is taken into account by multiplying 1 by the second weight coefficient by 1. Repeating the above step M i Summing the products obtained each time to obtain the ith 2 Importance.
Exemplary, the ith second service has an initial importance of 2, a first weight coefficient of 0.6, a target value of 1, and a third service M i The number of (3) is as follows: 3. 2 and 1. The control server determines the ith according to the product of the first weight coefficient and the initial importance of 0.6x2 1 The importance is 1.2.
The control server subtracts the first weight coefficient from the target value to obtain a second weight coefficient of 0.4. Control garmentThe server calculates the second weight coefficient and M i Product sum of importance of third service
0.4 x 3+0.4 x 2+0.4 x 1, determining the ith 2 The importance is 2.4.
Exemplary, the ith second service has an initial importance of 1, a first weight coefficient of 0.8, a target value of 2, and a third service M i The number of (2) is as follows: 3 and 1. The control server determines the ith according to the product of the first weight coefficient and the initial importance of 0.8 x 1 1 The importance is 0.8.
The control server subtracts the first weight coefficient from the target value to obtain a second weight coefficient of 1.2. The control server calculates a second weight coefficient and M i The product of the importance of the third service and 1.2x3+1.2x1, the ith is determined 2 The importance is 4.8.
Step 306, according to ith 1 Importance and ith 2 Importance, the ith importance of the ith second service is determined.
Optionally, the ith importance and the ith 1 The importance is positively correlated, the ith importance is with the ith 2 The importance is positively correlated.
In one example, according to ith 1 Importance and ith 2 And determining the ith importance of the ith second service.
Illustratively, the control server determines the ith 1 Importance of 0.6, ith 2 The importance is 0.8, and the i-th importance of the i-th second service is 1.4.
For example, the process of determining the i-th importance of the i-th second service may refer to the following equation 1:
in the above formula, vi 'represents the i-th importance of the i-th second service, P represents the first weight coefficient, vi represents the initial importance of the i-th second service, 1-P represents the second weight coefficient, N represents the number of all the services in the whole function, vim' is used to represent whether the m-th service of the N services is the third service, vim 'is 1 represents that the service is the third service, and Vim' is 0 represents that the service is not the third service.
In equation 1, ith 1 The importance is PVi, ith 2 Importance is thatIf a new service is added or an existing service is withdrawn during the service adjustment, the calling relationship between the services changes, and the importance of each service can be updated according to formula 1.
In summary, in the method provided in this embodiment, when the second service to be adjusted is determined according to the importance, the importance of the second service is more comprehensively and comprehensively determined from the perspective of the overall function by combining the importance of the third service calling the second service, so as to avoid the problem that the importance of one service is not accurate enough when the importance of the second service is determined only by a single parameter.
Meanwhile, according to the method provided by the embodiment, the relation among the services is abstracted into the directed acyclic network, and the calling relation among the services is determined more directly.
Moreover, by introducing the weight coefficient, the method provided by the embodiment can determine the initial importance of the second service and the importance of the third service calling the second service, and different influence degrees on the importance of the second service.
In an alternative embodiment based on fig. 3, fig. 5 shows a flowchart of a service adjustment method according to an exemplary embodiment of the present application, which is applied to a control server. In this embodiment, step 304 is alternatively implemented as: step 3041 and step 3042:
Step 3041, determining an adjustment sequence of the N second services according to the determined 1 st to N th importance;
alternatively, the control server may determine the order in which the adjustment operations are performed according to the determined 1 st to nth importance. For services of lower importance, the control server is more advanced in the adjustment operation.
Illustratively, N has a value of 2, i.e. there are two second services, and the corresponding importance is the 1 st importance and the 2 nd importance, respectively. Wherein, the 1 st importance is lower than the 2 nd importance, the order of the control server for adjusting operation is as follows: the 1 st second service, the 2 nd second service.
And step 3042, adjusting the T second services in turn according to the adjustment sequence until the service performance of the first service is not less than the threshold.
Illustratively, the control server performs an adjustment operation on the 1 st second service of the 3 second services according to the determined 1 st importance to the 3 rd importance, so that the performance of the first service is restored. The 1 st second service is the service with the lowest importance.
Illustratively, the control server performs an adjustment operation on 4 second services of the 4 second services, the adjustment order being service 1, service 2, service 3 to service 4, so that the performance of the first service is restored. The 1 st importance, 2 nd importance, 3 rd importance and 4 th importance of the service 1, the service 2, the service 3 to the service 4 are gradually increased relations.
In one example, the adjusting operation for the T second services includes: service degradation operations including at least one of closing the service, reducing software and hardware resource allocation, and suspending the service.
The control server realizes the protection of the first service through the adjustment operation of the second service.
Optionally, the service degradation operation includes a fusing operation, i.e., closing a service.
By taking the fusing operation, the second service will not send the call request to the first service any more, and for the subsequent call request, the control server directly returns the error information of the call failure to the second service.
By means of the fusing operation it is ensured that during the period when the service performance of the first service is below the threshold value, the invocation of the second service is returned immediately without blocking, thereby releasing the resources quickly.
Optionally, the service degradation operation includes a current limiting operation, i.e. reducing allocation of software and hardware resources.
The throttling operation is taken to essentially limit the number of cross-call requests between services. The control server returns a predetermined default value to the second service to which the streaming operation is performed without invoking the first service to process a call request sent by the second service to the first service.
In one example, the adjustment operation is canceled in response to the service performance of the first service being not less than the threshold.
Optionally, after the adjustment operation is performed for a predetermined period of time, for example, 80ms, the control server monitors the service performance of the first service again, and if the service performance of the first service is found to be not less than the threshold, the control server cancels the adjustment service for the T second services.
Optionally, the control server may directly cancel the adjustment services for the T second services at the same time, or may gradually cancel the adjustment services for the T second services according to a certain order. Such as: the control server gradually cancels the adjusting service of the T second services according to the importance of the T second services, and for the second services with higher importance, the control server cancels the adjusting service of the second services.
In summary, in the method provided in this embodiment, when the second service to be adjusted is determined according to the importance, the importance of the second service is more comprehensively and comprehensively determined from the perspective of the overall function by combining the importance of the third service calling the second service, so as to avoid the problem that the importance of one service is not accurate enough when the importance of the second service is determined only by a single parameter.
According to the method provided by the embodiment, the adjustment sequence is determined according to the obtained importance, and the second services are sequentially adjusted, so that the problem that the overall function is influenced due to excessive second services or the service performance of the first service cannot be recovered due to insufficient second services is solved.
In addition, according to the method provided by the embodiment, when the service performance of the first service is recovered, the adjustment operation is timely canceled, unnecessary adjustment operation is reduced, and the integrity of the whole function is ensured.

For one overall function, it is divided into ten fine-grained micro-services. As shown in fig. 6, the call relationship between the ten micro services (or simply "services") is translated into a directed acyclic graph of services. Each node in fig. 6 corresponds to a service, there is a call relationship between the services, and the directed edge points from the requestor of the service to the provider of the service. Such as service 10 needs to invoke service 5 and service 7.
According to manual settings, each service has an initial importance, defined as V1 to V10. And the server calculates the importance of each service according to the calling relation to obtain the final importance of each service.
For service 8, service 9 and service 10, the final importance V8', V9' and V10' of service 8, service 9 and service 10 are their own initial importance V8, V9 and V10, as there are no other services that need to invoke these three services.
Whereas for service 7, service 7 is invoked by service 8 and service 10, parameters affecting the final importance V7' of service 7 include: the initial importance V7 of service 7, the importance V8 'of service 8 and the importance V10' of service 10. The server sets weights for the parameters described above, calculating the final importance V7' of the service 7. Similarly, the server gradually determines the final importance V1', V2', V3', V4', V5 'and V6' of the other services.
The server monitors the service performance of each service, and finds that the service performance of the service 3 corresponding to the node 601 is smaller than a preset threshold value and is abnormal service. In order to ensure the availability of the service 3, the server determines, according to the call relationship, that the service 5 corresponding to the node 602 and the service 6 corresponding to the node 603 are the services to be adjusted. The server acquires the importance V5 'and V6' of the service 5 and the service 6, determines that the importance of the service 5 is lower after comparison, and performs adjustment operation on the service 5, such as fusing the service 5. At this time, the service performance of the service 3 will gradually increase.
