DETAILED DESCRIPTION

The principle of the present disclosure will be described below with reference to several example embodiments illustrated in the accompanying drawings. Although the drawings show preferred embodiments of the present disclosure, it should be understood that these embodiments are merely described to enable those skilled in the art to better understand and further implement the present disclosure, and not to limit the scope of the present disclosure in any way.

The term “include” and variants thereof used herein indicate open-ended inclusion, that is, “including but not limited to.” Unless specifically stated, the term “or” means “and/or.” The term “based on” means “based at least in part on.” The terms “an example embodiment” and “an embodiment” indicate “at least one example embodiment.” The term “another embodiment” indicates “at least one additional embodiment.” The terms “first,” “second,” and the like may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

As previously mentioned, some software may be generalized to more platforms for use. When used on multiple platforms, some features in the software may not be supported on some platforms. Unsupported features need to be disabled or hidden for specific platforms. Otherwise, it will bring bad user experience during use. Because the user will not know whether this is a bug or because it is not supported. However, there are too many features running in software, and there are also many supporting platforms. If there is no unified method to manage the feature availability, the user interface (UI) will be troubled by a lot of code logic. Moreover, if enabled states of certain features need to be modified in the future (for example, a client terminal purchases a different license, or the client terminal enables or disables certain features as needed), the UI code will have to be modified and refactored.

A solution for system feature management is proposed in the embodiments of the present disclosure, so that features of software can be managed in a unified manner. According to various embodiments of the present disclosure, a feature item set is loaded, and the feature item set includes multiple feature items respectively corresponding to multiple microservices. In response to an availability indicator of a first feature item indicating that the first feature item is unavailable, the first feature item is disabled.

According to the embodiments described herein, software runtime failures may be avoided by disabling, when the software is booted, those features that are not supported by the platform on which the software is running. In this way, software can be made to better adapt to more platforms. In addition, even if the user re-purchases a different service, the operator only needs to enable or disable the corresponding feature item, and does not need to redeploy to the user, thereby saving operating costs. The user may also choose to enable or disable the purchased service according to his/her own needs, so that the resources consumed by microservices running in the backend can be reduced.

The basic principle and some example implementations of the present disclosure will be described below with reference to the accompanying drawings. It should be understood that these example embodiments are given only to enable those skilled in the art to better understand and thus implement the embodiments of the present disclosure, and are not intended to limit the scope of the present disclosure in any way.

FIG. 1 is a schematic diagram of an example environment in which embodiments of the present disclosure can be implemented. As shown in FIG. 1, environment 100 includes system feature manager 110, client terminal 120, microservice 130, feature item library 140, and license manager 150. Client terminal 120 may communicate with system feature manager 110, microservice 130, and feature item library 140 through API gateway 160.

Microservice 130 may provide various services to client terminal 120. Although microservice 130 is shown as a whole, it should be understood that this is for ease of illustration only. In fact, microservice 130 may include one or more microservices (collectively or individually referred to as “microservice 130”) that may be communicatively coupled to each other and independently deployed. These microservices communicate with each other through a representational layer state transition (REST) API.

Any two of system feature manager 110, microservice 130, and feature item library 140 may communicate with each other. System feature manager 110 may obtain data from license manager 150.

In some embodiments, system feature manager 110 and microservice 130 may be arranged together. In some embodiments, system feature manager 110 and microservice 130 may be arranged separately, but can communicate with each other. The platform on which system feature manager 110 and microservice 130 run may be a local virtual machine, a public cloud, a cloud virtual machine, or the like. The scope of the present disclosure is not limited in this regard.

It should be understood that the structure and functions of environment 100 are described for illustrative purposes only and do not imply any limitation to the scope of the present disclosure. For example, the embodiments of the present disclosure may also be applied to an environment different from environment 100.

FIG. 2 is a flow chart of example method 200 for system feature management according to an embodiment of the present disclosure. For example, method 200 may be performed by system feature manager 110 as shown in FIG. 1. It should be understood that method 200 may also include additional actions not shown and/or may omit actions shown, and the scope of the present disclosure is not limited in this regard. Method 200 will be described in detail below with reference to FIG. 1 and FIG. 3.

At block 210, system feature manager 110 loads a feature item set that includes multiple feature items corresponding to multiple microservices, respectively. FIG. 3 shows code defining a feature item according to some embodiments of the present disclosure.

As shown in FIG. 3, in some embodiments, a feature item may include feature identifier 310, feature descriptor 320, availability indicator 330, and status indicator 340. Feature identifier 310 is an identifier that can uniquely identify the feature item. Feature descriptor 320 can describe the feature item and may be presented on a user interface in the form of options for presenting the feature item to a user.

Availability indicator 330 indicates whether the feature item is available. For example, if the service purchased by client terminal 120 does not include a microservice corresponding to the feature item, then availability indicator 330 should indicate that it is unavailable. In some embodiments, loading a feature item set may include obtaining license information for the multiple microservices. Then, availability indicators 330 in the feature item set are determined based on the license information. In the embodiment shown in FIG. 3, availability indicator 330 is represented by a field “available,” which indicates available when a value thereof equals to “true.” Conversely, a value “false” (not shown) may be used for indicating unavailable. In some other embodiments, “true” and “false” or “1” and “0” may be used for indicating available or unavailable, respectively, and the scope of the present disclosure is not limited in this regard.

Back to FIG. 2, at block 220, in response to availability indicator 330 of a first feature item in the feature item set indicating that the first feature item is unavailable, system feature manager 110 disables the first feature item. In this manner, even if the user re-purchases a different service, the operator only needs to enable or disable the corresponding feature item, and does not need to redeploy to the user, thereby saving operating costs.

In some embodiments, in response to status indicator 340 of the first feature item indicating that the first feature item is disabled, system feature manager 110 disables the first feature item.

Status indicator 340 may indicate whether the feature item is enabled while the feature item is available. For example, although the service purchased by client terminal 120 includes the microservice corresponding to the feature item, client terminal 120 may choose to enable or disable the feature item according to actual situation and needs. The enabling or disabling action of client terminal 120 may be transferred as metadata to feature item library 140, and stored as cached data for the feature item set in feature item library 140. In the embodiment shown in FIG. 3, status indicator 340 is represented by a field “status,” which indicates enabled when a value thereof equals to “ENABLED.” Conversely, a value “DISABLED” (not shown) may be used for indicating disabled. In some other embodiments, “ENABLED” and “DISABLED” or “1” and “0” may be used for indicating enabled or disabled, respectively, and the scope of the present disclosure is not limited in this regard.

In some embodiments, the feature item set may include a platform indicator for indicating the platform for which the feature item set is targeted. Based on the platform indicator of the feature item set, the feature item unsupported by the platform as indicated by the platform indicator is disabled. In this way, software runtime failures may be avoided by disabling, when the software is booted, those features that are not supported by the platform on which the software is running. In this way, software can be made to better adapt to more platforms.

In some embodiments, loading the feature item set may include determining status indicators 340 in the feature item set based on cached data for the feature item set. In this way, the user may choose to enable or disable the purchased service according to his/her own needs, so that the resources consumed by microservice 130 running in the backend can be reduced.

The feature item also includes API rule 360 as shown in FIG. 3, and API rule 360 indicates part of microservice 130 corresponding to the feature item. When a feature item is disabled, part of microservice 130 corresponding to the feature item may be disabled according to the API rule of the feature item. In this way, instead of disabling the entire microservice corresponding to the feature item, part of the services may be selectively disabled, and only some necessary services are retained. Therefore, the energy consumption is reduced while ensuring the normal operation of the software.

In some embodiments, some feature items in the feature item set may include, for example, association indicator 350 in FIG. 3. The association indicator indicates that the feature item is associated with corresponding microservice 130. At this point, if the feature item is disabled, microservice 130 associated with it will be disabled. In this way, because the feature item is associated with corresponding microservice 130, entire microservice 130 can be disabled by disabling the feature item without considering what kind of service is defined by the API rule in the feature item.

There may be dependencies between feature items. That is, microservice 130 corresponding to one feature item or part of this microservice 130 may depend on microservice 130 corresponding to another feature item or part of its service. In some embodiments, a second feature item in the feature item set may include one or more dependency indicators for indicating one or more upper-level feature items on which the second feature item depends.

When the second feature item having upper-level feature items is being enabled, the dependency relationship needs to be considered. FIG. 4 is a flow chart of example method 400 of enabling a second feature item depending on upper-level feature items according to some embodiments of the present disclosure. Method 400 may be performed also by system feature manager 110 as shown in FIG. 1. It should be understood that method 400 may also include additional actions not shown and/or may omit actions shown, and the scope of the present disclosure is not limited in this regard. Method 400 will be described in detail below with reference to FIG. 1 and FIG. 3.

At block 410, system feature manager 110 receives a request to transition the second feature item from disabled to enabled. Then, at block 420, system feature manager 110 determines whether availability indicator 330 of the second feature item indicates available. If availability indicator 330 indicates unavailable (“No” branch), it means that the service corresponding to the second feature item is unavailable (for example, the corresponding service has not been purchased), the second feature item cannot be enabled, and therefore, the request will be rejected by system feature manager 110 at block 450.

If availability indicator 330 of the second feature item indicates available (“Yes” branch), system feature manager 110 determines at block 430 whether status indicators 340 of one or more upper-level feature items of the second feature item all indicate enabled. As long as there is one upper-level feature item whose status indicator 340 indicates disabled, the second feature item cannot be enabled. This is because its corresponding service needs to depend on other services to be implemented. Therefore, the request will be rejected by system feature manager 110 at block 450.

If it is determined that status indicators 340 of the one or more upper-level feature items all indicate enabled, at block 440, system feature manager 110 enables the second feature item.

If an upper-level feature item is a parent feature item with a strong association relationship with the second feature item, the dependency relationship also needs to be considered when the upper-level feature item is disabled. If a request to transition a parent feature item from enabled to disabled is received, because the second feature item is a child feature item thereof, the second feature item, as the child feature item, is also disabled when the parent feature item is disabled. If there is another child feature item of the parent feature item, the another child feature item is also disabled.

If the dependency between the upper-level feature item and the second feature item is weak dependency, the second feature item may or may not be disabled when the upper-level feature item is disabled.

In this way, it can be ensured that enabling or disabling operations of feature items will not cause the features of software to be disordered.

FIG. 5 is a schematic block diagram of example device 500 that can be configured to implement an embodiment of the present disclosure. For example, system feature manager 110 as shown in FIG. 1 may be implemented by device 500.
