In accordance with an embodiment of the present application, there is provided an embodiment of a service invocation method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than here.
It should be noted that, in the embodiment of the present application, an Eureka registry, which is a registry of a service discovery framework employing an application-level service discovery mode, may be selected as an execution subject of the service invocation method in the embodiment of the present application.
Fig. 1 is a flowchart of an alternative service invocation method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S101, receiving a service calling request sent by a service consumer.
In step S101, the service invocation request at least includes a target area identifier and a target service identifier, where the target area identifier is used to characterize an area where the service consumer is located, and the target service identifier is used to characterize a target service that the service consumer requests to invoke.
Specifically, the target service may be a micro service, and the service consumer may be a device for invoking the micro service, where the device for invoking the micro service may be a terminal device such as a smart phone, a notebook computer, a desktop computer, a smart tablet, and a smart wearable device, and may also be a server device such as a local server and a cloud server. For example, the service consumer may send a service invocation request to the Eureka registry, where the service invocation request includes a target area identifier, e.g., region a, and the service invocation request also includes a target service identifier, e.g., serviceA.
It should be noted that the area range represented by the target area identifier may be set in a customized manner, for example, the area range may be a city, such as area a representing beijing city and area B representing shanghai city. The region scope may also characterize different regions of a city, such as region C characterizing the great happy region of beijing city and region D characterizing the sunny region of beijing city. The size of the area range can be determined according to actual conditions.
In an alternative embodiment, before receiving the service invocation request sent by the service consumer, the Eureka registry registers the respective feature attributes as metadata information to the Eureka registry, where the service provider may be understood as an application providing a micro service for the service provider, for example, the service provider may be a server or a server cluster running the micro service; the characteristic attribute includes at least the region information of each service provider, for example, the geographical region, administrative region, and data center location where the service provider is located.
Optionally, each service provider registers, in addition to the feature attribute in the Eureka registration center, service instance information in the Eureka registration center, where the service instance information at least includes a service identifier of a microservice running on the service provider, an IP address of the service provider, and a data communication port. The service identification may also be understood as a service name of the microservice.
Step S102, responding to the service calling request, and determining a first service provider from a plurality of service providers.
In step S102, the service provider is configured to provide a service for the service consumer, the first service provider is located in the same area as the service consumer, and the target service runs on the first service provider.
Specifically, after receiving the service invocation request, the Eureka registration center first obtains an area identifier and a service identifier of each service provider, where the area identifier is used to characterize an area where each service provider is located, and the service identifier is used to characterize a service running on each service provider. Then, the Eureka registry determines at least two third service providers from the plurality of service providers according to the target service identifier, wherein the service identifier of the third service provider is the target service identifier, and the at least two third service providers are located in different regions. Finally, the Eureka registry determines the first service provider from the at least two third service providers according to the target area identifier, wherein the area identifier of the first service provider is the target area identifier.
As can be seen from the content introduced in step S101, the Eureka registry has registered the feature attribute and the service instance information of each service provider in advance, and the feature attribute includes the location area information of each service provider, and the service instance information includes the service identifier of the micro service running on the service provider, so that the Eureka registry can directly obtain the location area identifier and the service identifier of each service provider. On the basis, the Eureka registration center firstly screens out at least two third service providers from the plurality of service providers according to the target service identifier in the service invocation request, wherein the service identifier of the third service provider is the target service identifier. For example, the service name of the micro service requested to be called by the service consumer is serviceA (i.e., the target service identifier is serviceA), and after receiving the target service identifier identifying serviceA, the Eureka registry generates a service information list, where all of the plurality of service providers (i.e., third service providers) in the service information list run the micro service of serviceA. It should be noted that the plurality of service providers in the service information list are located in different areas.
In addition, after obtaining the at least two third service providers, the Eureka registry further determines the first service provider from the at least two third service providers according to the target area identifier, wherein the area identifier of the first service provider is the target area identifier. Still taking the generated service information list as an example, the service information list further includes an area identifier of each third service provider, and on this basis, by comparing the area identifier of each third service provider with the target area identifier of the service consumer, the Eureka registry can determine from the service information list which third service provider is located in the same area as the service consumer, and determine the third service provider located in the same area as the service consumer as the first service provider.
Step S103, detecting whether the current load rate of the first service provider is greater than a preset threshold.
In step S103, the current load rate of the service provider may be determined according to the current free memory size of the service provider, the current CPU operating speed, and the current network bandwidth, for example, in general, the larger the current free memory of the service provider is, the lower the current load rate of the service provider is; the faster the current CPU running speed of the service provider is, the lower the current load rate of the service provider is; the larger the current network bandwidth of the service provider, the lower the current load rate of the service provider. On the basis, the Eureka registry can respectively give different weights to the current free memory size, the current CPU operating speed and the current network bandwidth of the service provider, and calculate to obtain a weighting result, and finally, the Eureka registry determines the current load rate of the service provider according to the weighting result.
And step S104, determining the first service provider as a target service provider under the condition that the current load rate of the first service provider is smaller than a preset threshold value.
In step S104, the target service provider is used to provide the target service for the service consumer. The preset threshold value can be set by self-definition. After determining the first service provider, the Eureka registry does not directly provide the target service for the service consumer with the first service provider as the target service provider, but first detects the current load rate of the first service provider, and then determines the first service provider as the target service provider only if the current load rate of the first service provider is smaller than a preset threshold.
It should be noted that, the farther the distance between the service consumer and the service provider is, the larger the network resource to be consumed between the service consumer and the service provider is, and the more unexpected factors exist in the communication process, the problem of poor communication quality is likely to occur. For example, if a service consumer located in Beijing requests to invoke a microservice, the optimal way to invoke is to have the microservice provided by the service provider also located in Beijing. However, since the service providers are selected in a random distribution manner in the prior art, the prior art is likely to select service providers in other areas to provide micro-services for the service consumers, such as the service providers located in shanghai. In order to solve the problem in the prior art, the method and the device design a policy with the priority of the same region, and preferentially select the first service provider as the target service provider under the condition that the current load rate of the first service provider located in the same region as the service consumption direction is smaller than a preset threshold value, so that unnecessary network resource consumption is reduced to the maximum extent on the premise that the first service provider can stably provide micro services for the service consumer, and the utilization rate of network resources is improved.
And step S105, determining a second service provider as a target service provider from a plurality of service providers under the condition that the current load rate of the first service provider is greater than or equal to a preset threshold value.
In step S105, the second service provider is located in a different area from the first service provider, a current load rate of the second service provider is smaller than a preset threshold, and the second service provider also runs a target service.
Specifically, when the current load rate of the first service provider is greater than or equal to the preset threshold, it indicates that the first service provider is not suitable for providing the target service for the service consumer at the current time, and if the first service provider is forcibly used as the target service provider to provide the target service for the service consumer, problems of slow target service invocation speed, and jamming or even breakdown in the invocation process may occur, and further increase of the load rate of the first service provider may also cause an influence on a process already running in the first service provider. Therefore, in order to avoid this problem, when the current load rate of the first service provider is greater than or equal to a preset threshold, the Eureka registry may select a second service provider as a target service provider from service providers in other areas, and the current load rate of the second service provider is less than the preset threshold.
In an alternative embodiment, in an area where a service consumer is located, multiple first service providers capable of providing a target service for the service consumer may exist at the same time, on this basis, the Eureka registry may obtain a current load rate of each first service provider respectively, rank all the current load rates, determine, if all the current load rates are greater than or equal to a preset threshold, a second service provider in another area as a target service provider, and if at least one first service provider whose current load rate is less than the preset threshold exists, determine, by the Eureka registry, a first service provider whose current load rate is the smallest as a target service provider.
For example, a service consumer a is located in beijing, the micro-service requested by the service consumer a is serviceB, and 3 service providers in a machine room in beijing can provide the micro-service of serviceB for the service consumer a. On the basis that all the 3 service providers can serve as first service providers corresponding to the service consumer a, the Eureka registration center can respectively obtain current load rates of the 3 service providers, so as to obtain 3 current load rates, and when all the 3 current load rates are greater than or equal to a preset threshold, the Eureka registration center determines a second service provider as a target service provider from other areas; when at least one current load rate is smaller than the preset threshold value in the 3 current load rates, the Eureka registration center ranks the at least one current load rate, and takes the first service provider with the smallest current load rate as the target service provider.
Based on the contents of the above steps S101 to S105, in the embodiment of the present application, a method of determining a target service provider providing a target service for a service consumer according to a location area and a current load rate of the service provider is adopted, and first, after receiving a service invocation request sent by the service consumer, determining a first service provider from a plurality of service providers in response to the service invocation request, where the service invocation request at least includes a target area identifier and a target service identifier, the target area identifier is used for characterizing the location area of the service consumer, and the target service identifier is used for characterizing a target service requested to be invoked by the service consumer; the first service provider is located in the same area as the service consumption direction, and the target service runs on the first service provider. Then, detecting whether the current load rate of the first service provider is greater than a preset threshold value; determining the first service provider as a target service provider under the condition that the current load rate of the first service provider is smaller than a preset threshold, wherein the target service provider is used for providing target services for service consumers; and under the condition that the current load rate of the first service provider is greater than or equal to a preset threshold value, determining a second service provider as a target service provider from a plurality of service providers, wherein the second service provider and the first service provider are located in different areas, the current load rate of the second service provider is smaller than the preset threshold value, and the target service is operated on the second service provider.
As can be seen from the above, according to the present application, after receiving a service invocation request sent by a service consumer, a first service provider belonging to the same area as the service consumer is first used as a preferred service provider for processing the service invocation request, and as the distance between the service provider and the service consumer is longer, the network resource consumption is larger, therefore, the first service provider is selected as the preferred service provider, which can reduce unnecessary network resource consumption, thereby improving the network resource utilization rate. In addition, the current load rate of the first service provider is detected, and if the current load rate of the first service provider is too high (greater than or equal to a preset threshold), the second service provider with the lower current load rate in other areas is selected as the target service provider for providing the target service for the service consumer, so that the problem of poor service calling stability when the first service provider is forcibly used for providing the target service for the service consumer can be avoided, and the service calling efficiency is improved.
Therefore, through the technical scheme of the application, the purpose of flexibly selecting the service providers in different areas to provide the target service for the service consumers is achieved, the effect of improving the service calling stability is achieved, and the technical problem that the service calling efficiency is low due to the fact that the service calling request of the micro-service cannot be processed across areas in the prior art is solved.
In an alternative embodiment, in the case that the current load rate of the first service provider is greater than or equal to the preset threshold, the Eureka registry first determines at least one candidate service provider from among the at least two third service providers, then determines the second service provider from among the at least one candidate service provider according to the current load rate of the candidate service provider, and determines the second service provider as the target service provider. And the current load rate of the candidate service provider is smaller than a preset threshold, and the candidate service provider and the first service provider are located in different areas.
Optionally, the at least two third service providers at least include a first service provider and other service providers, where the other service providers and the first service provider are located in different areas, and when the current load rate of the first service provider is greater than or equal to a preset threshold, the Eureka registration center detects the current load rate of the other service providers, and selects a service provider whose current load rate is less than the preset threshold as a candidate service provider. Since there may be a plurality of candidate service providers, the Eureka registry further selects a second service provider according to the current load rate of the candidate service provider, and determines the second service provider as the target service provider.
In an alternative embodiment, the Eureka registry may rank the current load rates of at least one candidate service provider to obtain a ranking result, and then the Eureka registry determines the candidate service provider with the smallest current load rate as the second service provider according to the ranking result. The candidate service provider with the minimum current load rate is selected as the second service provider, and the service provider with the minimum load rate at the current time can be ensured to be selected to provide target service for the service consumer, so that the response efficiency of the service call request of the service consumer is improved.
In an alternative embodiment, the Eureka registry obtains the current load rate corresponding to the candidate service provider at each time within a preset time period, where the preset time period includes multiple times. And then the Eureka registration center determines the median of a plurality of current load rates of the candidate service providers in a preset time period according to the current load rate corresponding to the candidate service providers at each moment, and finally determines the candidate service provider with the minimum median as a second service provider.
Optionally, the preset time period may be set in a self-defined manner, for example, the preset time period may be half an hour, and the Eureka registration center may obtain the current load rate of each candidate service provider per minute within half an hour, that is, each candidate service provider correspondingly obtains 30 current load rates, and the Eureka registration center may select a median according to the 30 current load rates. In the case of multiple candidate service providers, the Eureka registry will obtain multiple medians, each corresponding to one candidate service provider. Finally, the Eureka registry determines the candidate service provider with the smallest median as the second service provider. It should be noted that the median may characterize the load rate change of one candidate service provider in a preset time period to a certain extent, and therefore, selecting the candidate service provider with the smallest median as the second service provider may ensure that the service provider with a smaller load rate and a smaller load rate change fluctuation is selected to provide the target service for the service consumer.
In an alternative embodiment, the Eureka registry may further determine the area where the service consumer is located according to the target area identifier, determine the area where the candidate service provider is located according to the area identifier of the candidate service provider, and then determine the distance between the candidate service provider and the service consumer based on the area where the service consumer is located and the area where the candidate service provider is located, and determine the candidate service provider with the shortest distance as the second service provider.
Optionally, the present application further provides another way to select the second service provider, that is, the second service provider is determined according to the distance between the candidate service provider and the service consumer. Since the target area identifier represents the area where the service consumer is located, and the area identifier of the candidate service provider represents the area where the candidate service provider is located, the Eureka registry can determine the area where the service consumer is located and the area where the candidate service provider is located according to the target area identifier and the area identifier of the candidate service provider. On this basis, the Eureka registry can also determine the distance between the service consumer's location and the candidate service provider's location. Since the longer the communication distance between the service consumer and the service provider, the larger the network resources it consumes, the Eureka registry will determine the candidate service provider with the shortest distance to the service consumer as the second service provider.
In an alternative embodiment, after determining that the first service provider is the target service provider, the Eureka registry further obtains a call success rate when the service consumer calls the target service from the first service provider, and in a case that the call success rate is less than a preset success rate, the Eureka registry determines that the second service provider is the target service provider from the plurality of service providers.
Optionally, in an actual application, a first service provider located in the same area as the service consumption may have a call exception, for example, the first service provider suddenly fails, so that the call is not possible. In order to avoid the problem that no other service provider provides target service for the service consumer when the first service provider is abnormal, the method monitors the calling success rate of the service consumer calling the target service from the first service provider in real time after the first service provider is determined to be the target service provider, and if the calling success rate is smaller than the preset success rate, the Eureka registration center determines the second service provider as the target service provider from a plurality of service providers. The selection process of the second service provider is already described in the above, and will not be described in detail herein.
It should be noted that, if there are a plurality of first service providers in the area where the service consumer is located, the current load rate of which is less than the preset threshold, the Eureka registry may determine that the first service provider with the smallest current load rate is the target service provider, and when the call success rate of the target service provider is less than the preset success rate, the Eureka registration center determines the first service provider as an abnormal service provider, and then re-detecting the current load rate of each first service provider, if there is at least one first service provider whose current load rate is less than a preset threshold, the Eureka registry will re-determine the first service provider with the smallest current load rate as the new target service provider, if the current load rates of all the first service providers are greater than or equal to the preset threshold, the Eureka registry determines the second service provider as the target service provider from the plurality of service providers.
Therefore, according to the technical scheme, the target service provider is determined according to the call success rate, the purpose that service providers in other areas are reselected as the target service provider when the first service provider is abnormal is achieved, and therefore the stability of service call is improved.
