Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In the related art, for a software developer, the PaaS service mode can reduce development cost and relieve development pressure. As a sub-division mode in the PaaS Service mode, FaaS (Function as a Service) which is a newer Service mode is proposed. The FaaS only needs to pay attention to the service code logic and does not need to pay attention to server resources, so the FaaS is also closely related to Serverless (i.e. developers do not need to pay attention to the server). FaaS provides a more subdivided and abstract servitization capability, which enables developers to concentrate on "what to do" by making the complex server architecture transparent, thereby emphasizing the idea of reducing the developer's attention to computing resources such as servers and switching the work granularity from server to task.
Taking e-commerce application as an example, the services can be divided into decoupled functional services such as browsing commodities, adding shopping carts, placing orders, paying, checking logistics and the like. In FaaS, it may split an e-commerce application into opcodes that a user may use, e.g., add, read queries, update, delete opcodes. For example, when an "order placing" event occurs, a corresponding functional service is triggered and handed to the FaaS server for execution.
At present, FaaS is supported by Cloud computing manufacturers, such as Amazon products like Lambda, Azure Function and Google Cloud Functions. This architecture requires computing to be done with the cloud computing vendor's server. On one hand, the FaaS has a difficulty in functional service of the subsequent business, and currently, common service frameworks generally use products such as Dubbo, spring cloud, and the like, but the construction of the whole service system needs coding support, and related personnel need to manually adjust the compatibility of one or more software programs and the whole system when constructing the service system, and cannot realize the function automatically. On the other hand, since support by a cloud computing vendor is required, it is necessary to expose a functional service to a public cloud provided by the cloud computing vendor, and it is difficult to construct an entire service system using a private cloud within an enterprise, and therefore, it is not easy to construct an entire service system based on FaaS.
As described above, in the conventional service system, it is necessary for a developer of a functional service of a service provider to pay attention not only to development of a program for providing the functional service but also to be familiar with a framework of the entire service system, and to add the developed program to the entire service system by further encoding after the program development is completed, so as to be used by an external client. Because the framework of the service system is difficult to construct, products such as Dubbo, spring cloud and the like of cloud computing manufacturers are generally used, but the process of adding the developed program into the service system still needs coding support and cannot be automatically realized. Moreover, since support of a cloud computing vendor is required, functional services need to be exposed to a public cloud provided by the cloud computing vendor, and many services inside an enterprise are not expected to be exposed to the outside, so that products of the public cloud cannot be used, and the entire service system needs to be constructed by using a private cloud inside the enterprise.
In such a background, the inventors of the present disclosure conceive of: by automatically registering and exposing the functional service to the whole service system, the work required for constructing the service system can be reduced, so that the service system can be constructed quickly, and the burden of a program developer is reduced. Therefore, the service system can be constructed by utilizing the private cloud in the enterprise, and the process that a program developer adds the developed program into the whole service system through further coding can be omitted.
Embodiments of the present disclosure provide a service system. The service system comprises an application program module, an information management module and a scheduling processing module. The application module includes one or more applications, each application including one or more functional services, each of the one or more functional services each having a corresponding tag. The information management module is used for receiving the registration of each functional service based on the corresponding label of each functional service and generating a functional service information list based on the information of the registered functional service. The scheduling processing module is used for scheduling the functional service for responding to the client request from the functional service information list according to the client request from the outside.
Fig. 1 schematically shows an application scenario of a service system according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a service system to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in FIG. 1, the service objects of the service system 100 may include program developers and external clients. The service system 100 can accept a plurality of client requests from different clients, respond to each client request, and feed back a response result to the client. Meanwhile, the service system 100 may receive the latest application program written from the program developer to implement the maintenance, update and refinement of the functional service.
The service system 100 may be configured by, for example, a distributed server cluster, and thus has a good arithmetic processing capability. For a client such as a consumer, it is only necessary to perform a simple operation on a client terminal used by the client, and the client request is transmitted to the service system 100, and a response result is obtained from the service system 100. In other words, the service system 100 composed of a plurality of distributed server clusters may be an information interaction terminal exposed to an external client, and the structural composition and the operation manner of the information interaction terminal are unknown to the external client.
Specifically, as shown in fig. 1, the service system 100 of the embodiment of the present disclosure includes an application module 110, an information management module 120, and a schedule processing module 130. The application module 110 may be oriented to a program developer and the dispatch processing module 130 may be oriented to an external client. A complete automatic processing flow can be achieved through the cooperative action among the three modules, and a program developer only needs to pay attention to the application program module 110, but does not need to pay attention to other modules.
The application module 110 includes one or more applications. One or more of the applications in the application module 110 may be, for example, Java applications, developed by a program developer. Specifically, for example, the application module 110 provides a Java application service, and may be constructed using Spring Boot + Spring MVC, and quickly build a Java application framework through Spring Boot, and process a client request through Spring MVC. The client request is, for example, an http request (request message from the client to the server). The Spring framework is an open source application framework on the Java platform, and provides a large number of web frameworks for development convenience. The Spring Boot is designed based on Spring4.0, not only inherits the original characteristics of a Spring framework, but also further simplifies the whole construction and development process of Spring application by simplifying configuration. Spring MVC is also based on a Spring framework and is mainly used for supporting the development of web applications.
Multiple applications may be developed by different program developers and multiple applications may be distributed on different servers. In other words, an application in application module 110 may be a cluster of applications on one or more servers, in accordance with embodiments of the present disclosure.
Each application includes one or more functional services. The "functional service" herein refers to a functional service that is registered with and exposed to the entire service system. For example, a Java application service as a functional service may be automatically registered to a service system using etcd and exposed as an http service. etcd is an open-source, distributed key-value pair data storage system that provides for the registration and discovery of shared configurations, services.
Each of the one or more functional services each has a corresponding tag, and the corresponding tag for each functional service may be the same without the need for a special definition tag. For example, each functional service to be automatically exposed as an http service has an identical corresponding tag for indicating that the functional service is to be exposed as an http service. For example, an annotation @ FaaSService may be added to each feature service to be automatically exposed as an http service.
The information management module 120 is configured to accept registration of each functional service based on a corresponding tag of each functional service, and generate a functional service information list based on information of the registered functional service. In other words, the information management module 120 accepts and accepts only registration of the functional service having the corresponding tag. Since each functional service to be exposed will have an identical corresponding tag, it is easy to identify. And, the information management module 120 generates a function service information list based on the information of the registered function service. The information of the functional service may include at least one of: application name (APPname), Fully qualified class name (full qualified class name), Parameter name (Parameter name), Parameter Type (Parameter Type), and IP address (IP address). Through the information of the functional services, a specific functional service can be quickly identified and determined.
The scheduling processing module 130 is configured to schedule a functional service for responding to a client request from the functional service information list according to the client request from the outside. The dispatch handling module 130 is for example implemented using ngx _ lua. ngx _ Lua is a high-performance Web platform based on Nginx and Lua, and can realize the scheduling processing module 130 by means of a characteristic dynamic deployment function of the Lua dynamic scripting language. Nginx is a high-performance HTTP and reverse proxy web server, lua is a scripting language, can be written by standard C, and can be compiled and run on almost all operating systems and platforms.
The client request from the outside is issued by an external user of the service system 100. A client, such as a consumer, performs a simple click operation on a client terminal, and the client terminal automatically recognizes the operation as a client request of a certain format and sends the client request to the scheduling processing module 130. The client request includes at least one information of the same type as the information of the function service in the function service information list. Thus, the scheduling processing module 130 can quickly match at least one piece of information included in the client request with the information of the functional services in the functional service information list, and determine whether or not there are functional services capable of responding to the client request and several functional services capable of responding to the client request in the functional service information list. After judging that the functional service capable of responding to the client request exists in the functional service information list, quickly determining the functional service, and sending the client request from the outside to the determined functional service for processing.
For example, when the client request is an http request, the request format may be? app & service & parameter value & … …. After receiving the http request with the request format, the scheduling processing module 130 matches the information of the functional services in the service information list, and determines whether the functional services capable of responding to the http request and several functional services capable of responding to the http request exist in the functional service information list. And after judging that the functional service capable of responding to the http request exists in the functional service information list, quickly determining the functional service, and sending the http request to the determined functional service for processing. In addition, the http request may also be sent to an application program including a functional service capable of responding to the http request, and the application program invokes the corresponding functional service to process the http request according to format information of the http request.
According to the embodiment of the disclosure, the automatic registration and exposure of the functional service in the application program to the whole service system can be realized, the work required for constructing the service system is reduced, the service system is easy to construct, and the burden of a program developer is reduced. Therefore, the service system can be constructed by utilizing the private cloud in the enterprise, and the process that a program developer adds the developed program into the whole service system through further coding can be omitted.
Through the embodiment of the disclosure, after the related personnel develop the application program, the application program module can automatically register the functional service with the specific label to the information management module, and the information management module can maintain the functional service information list, so that the automatic registration of the functional service in the application program module can be realized. The technical problems that in the related art, due to the fact that a cloud computing service system is complex, related personnel need to manually adjust the compatibility of one or more software programs and the whole system when the cloud computing service system is built, the building process of the cloud computing service system is time-consuming and labor-consuming, and building efficiency is low are solved, developers only need to complete the development of application programs, and do not need to pay attention to the compatibility of the developed programs and the service system, and the technical effect of improving the building efficiency of the built service system is achieved.
Fig. 2 schematically shows a schematic diagram of the operation of a service system according to an embodiment of the present disclosure.
As shown in FIG. 2, a program developer provides one or more functional services in an application to application module 110, for example, by deploying the developed application to application module 110. After acquiring the functional service, the application module 110 registers the functional service having the corresponding tag in the information management module 120. The information management module 120 generates a function service information list based on the information of the registered function service. The scheduling processing module 130 receives a client request from the outside, and searches the function service information list of the information management module 120 for information of a function service for responding to the client request. Then, the scheduling processing module 130 calls a corresponding functional service from the application module 110 according to the queried information of the functional service, in response to the client request. Alternatively, the administrator may perform some actions of management, authorization, etc. on the information management module 120 from the terminal where the administrator is located.
FIG. 3 schematically shows an example block diagram of an information management module in accordance with an embodiment of this disclosure.
As shown in fig. 3, the information management module 120 of the embodiment of the present disclosure may include an information registration unit 310 and an information deletion unit 320.
The information registration unit 310 may be configured to store a functional service information list, and when any of one or more application programs starts, accept registration of each of the functional services in the application program, and add information of the registered functional service to the functional service information list.
When the application module 110 is first started, all the functional services with the corresponding tags are registered with the information registration unit 310 of the information management module 120. The information registration unit 310 accepts registration of each functional service with a corresponding tag, and generates a functional service information list based on information of the registered functional service. The functional service information list includes specific information of the functional service and is always stored in the information registration unit 310.
The application modules 110 include one or more applications developed by a program developer. Also, the applications included in the application module 110 may be dynamically changing. For example, a program developer may add newly developed applications to application module 110 or may remove applications that are no longer in use from application module 110. Since the application programs in the application program module 110 can be added and deleted, the functional services used by the service system will be changed accordingly.
For example, in the case where a program developer adds a newly developed application to the application module 110, when the application starts, the application module 110 registers a functional service with a corresponding tag in the application to the information registration unit 310. The information registration unit 310 has stored therein a function service information list, and thus directly adds information of the registered function service to the function service information list.
The information deleting unit 320 may be configured to delete the information of each functional service in any application from the functional service information list when the application stops running.
For example, when a program developer deletes an application from the application module 110 or stops the operation of a load that runs the application, the application stops running. The application stopping running means that the functional service in the application also becomes unavailable.
The information deleting unit 320 maintains communication with the application module 110, and deletes information of some functional services from the functional service information list when the functional services in the application module 110 cannot be detected. Thereby, it can be ensured that all the functional services registered in the functional service information list are available functional services.
For example, in the case where the functional service in the application module 110 is a Java application service, the Java application service may be registered with the functional service information list when it is started by Spring Boot, and then information is deleted from the functional service information list by the information deleting unit 320 when the JVM stops running.
FIG. 4 schematically shows an example block diagram of an information management module in accordance with an embodiment of this disclosure.
As shown in fig. 4, unlike the information management module 120 shown in fig. 3, the information management module 120A may include an information auditing unit 430 in addition to the information registering unit 410 and the information deleting unit 420.
The information auditing unit 430 is configured to audit the functional service before the functional service in the application is registered in the information registering unit, and allow the functional service to be registered after the audit is passed. By the setting of the information auditing unit 430, the quality of the functional service registered in the functional service information list can be ensured. The information registration unit 410 and the information deletion unit 420 in the information management module 120A have functions corresponding to the information registration unit 310 and the information deletion unit 320 in the information management module 120.
FIG. 5 schematically shows an example block diagram of an information management module in accordance with an embodiment of this disclosure.
As shown in fig. 5, unlike the information management module 120 shown in fig. 3, the information management module 120B may include a right management unit 530 in addition to the information registration unit 510 and the information deletion unit 520. The information registration unit 510 and the information deletion unit 520 in the information management module 120B have functions corresponding to the information registration unit 310 and the information deletion unit 320 in the information management module 120.
The authority management unit 530 is configured to manage the scheduling authority of the scheduling processing module based on one or more functional services in the functional service information list. For example, the authority management unit 530 may set a scheduling authority for one or more functional services in the functional service information list, and limit the scheduling behavior of the scheduling processing module for the part of the functional services. Specifically, an authorization link may be set for the part of the functional service, and when a certain functional service is called, an authorization code needs to be applied first to allow the calling. Thus, on the one hand, the functional service can be protected from being abused, and on the other hand, the use condition of the functional service can be known.
Fig. 6 schematically illustrates an example block diagram of a scheduling processing module in accordance with an embodiment of this disclosure.
As shown in fig. 6, the scheduling processing module 130 may include an accepting unit 610, a querying unit 620, and a calling unit 630.
The accepting unit 610 may be configured to accept a client request from the outside and determine a functional service required to respond to the client request. The client request from the outside has certain format information, and the accepting unit 610 can determine which kind of functional service can respond to the client request according to the format information.
The querying unit 620 may be configured to query the functional service information list for information of functional services required to respond to the client request, and determine one or more functional services capable of responding to the client request according to the information. The client request includes at least one information of the same type as the information of the function service in the function service information list. Accordingly, the query unit 620 can quickly match at least one information included in the client request with the information of the functional services in the functional service information list, and determine whether there are functional services capable of responding to the client request and several functional services capable of responding to the client request in the functional service information list.
The invoking unit 630 may be configured to invoke a corresponding functional service in the application according to the information of the one or more functional services, so as to respond to a client request from the outside. The invoking unit 630, after determining that there is a functional service capable of responding to the client request in the functional service information list, quickly determines the functional service, and sends the client request from the outside to the determined functional service for processing.
Fig. 7 schematically illustrates an example block diagram of a scheduling processing module in accordance with an embodiment of this disclosure.
As shown in fig. 7, unlike the scheduling processing module 130 shown in fig. 6, the scheduling processing module 130A may include a load balancing unit 740 in addition to the accepting unit 710, the querying unit 720, and the calling unit 730. The accepting unit 710, the querying unit 720, and the calling unit 730 in the scheduling processing module 130A have functions corresponding to the accepting unit 610, the querying unit 620, and the calling unit 630 in the scheduling processing module 130.
The load balancing unit 740 is configured to generate a function service calling scheme capable of achieving load balancing based on the information of the one or more function services. When there are multiple functional services capable of responding to the client request, the load balancing unit 740 analyzes the usage and load configuration of the multiple functional services to obtain a functional service call scheme capable of achieving load balancing, that is, an optimal selection scheme for the functional service capable of responding to the client request.
In a case where the load balancing unit 740 thus gives the function service calling scheme, the calling unit 730 directly calls a corresponding function service in the application program according to the function service calling scheme in order to respond to a client request from the outside.
Fig. 8 schematically illustrates an example block diagram of a scheduling processing module in accordance with an embodiment of this disclosure.
As shown in fig. 8, unlike the scheduling processing module 130 shown in fig. 6, the scheduling processing module 130B may include a list sharing unit 840 in addition to the accepting unit 810, the querying unit 820, and the calling unit 830. The receiving unit 810, the querying unit 820, and the calling unit 830 in the scheduling processing module 130B have functions corresponding to the receiving unit 610, the querying unit 620, and the calling unit 630 in the scheduling processing module 130. The list sharing unit 840 is configured to obtain the latest function service information list from the information management module at preset time intervals to provide the query unit with a query. If the list sharing unit 840 is provided, the scheduling processing module 130B may not need to communicate with the information management module each time a client request is processed, saving processing flow.
In the case that the functional service is a Java application service, the list sharing unit 840 may be implemented by using nginnx, and an init _ worker _ by _ lua of ngx _ lua starts a timer, and the information registration unit of the information management module periodically pulls a latest functional service information list and updates the latest functional service information list to the list sharing unit 840. The load balancing unit 740 may be implemented by using the balance _ by _ lua of ngx _ lua, and may perform dynamic load balancing by using the function service information list stored in the list sharing unit 840 when scheduling the function service.
FIG. 9 schematically shows a schematic diagram of the operation of a scheduling processing module according to an embodiment of the disclosure.
Fig. 9 shows a case where the scheduling processing module 130C includes an accepting unit 910, a querying unit 920, a load balancing unit 930, a calling unit 940, and a list sharing unit 950. The reception unit 910 receives a client request from the outside, specifies a functional service required to respond to the client request, and transmits information on the required functional service to the query unit 920.
The list sharing unit 950 acquires the latest function service information list from the information management module 120 at every preset time to provide to the inquiring unit 920 for inquiry.
The querying unit 920 queries the information of the functional service required to respond to the client request from the functional service information list of the list sharing unit 950, determines one or more functional services capable of responding to the client request according to the information, and then sends the determined functional services to the load balancing unit 930.
The load balancing unit 930 generates a function service calling plan capable of achieving load balancing based on the information of the function service received from the querying unit 920, and then transmits the function service calling plan to the calling unit 940.
The calling unit 940 calls a corresponding function service in the application module 110 according to the received function service calling scheme in order to respond to a client request from the outside.
Another aspect of the present disclosure provides a method performed by the service system described above.
Fig. 10 schematically shows a partial flow diagram of a method performed by a service system according to an embodiment of the present disclosure.
As shown in fig. 10, the method of this portion includes operations S1010 to S1030.
In operation S1010, the service system acquires one or more application programs, each application program including one or more functional services, each of the one or more functional services each having a corresponding tag. The one or more applications are developed by a program developer.
In operation S1020, the service system registers each functional service based on a corresponding tag of each functional service in any application when the application is started, and generates a functional service information list based on information of the registered functional service.
In operation S1030, the service system deletes information of each functional service in any application from the functional service information list when the application stops running.
As can be seen from the above description, the service system performs operations S1010 to S1030, and can automatically complete registration and deletion of the functional service in the application program. So that the program developer can concentrate on the program development itself and does not need to deploy the application program developed by the program developer to the service system through coding.
The service system described above is also capable of performing the method shown in fig. 11 according to an embodiment of the present disclosure.
Fig. 11 schematically shows a partial flow diagram of a method performed by a service system according to an embodiment of the present disclosure. The portion of the method shown in FIG. 11 is directed to the external client that makes the client request.
As shown in fig. 11, the method of this portion includes operations S1110 to S1130.
In operation S1110, the service system accepts a client request from the outside and determines a functional service required to respond to the client request.
In operation S1120, the service system queries information of a functional service required in response to the client request from the functional service information list, and determines one or more functional services capable of responding to the client request according to the information.
In operation S1130, the service system calls a corresponding functional service in the application according to information of one or more functional services in order to respond to a client request from the outside.
For an external client sending a client request, the client terminal where the external client is located is simply operated to send the client request to the service system and obtain a response result from the service system. In other words, the service system is only one information interaction terminal which is exposed in front of the external client, and the structural composition and the operation mode of the service system are unknown to the external client and are not needed to be considered by the external client.
It should be noted that the method portion in the embodiment of the present disclosure corresponds to the service system portion in the embodiment of the present disclosure, and the description of the method portion specifically refers to the service system portion, which is not described herein again.
