[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0061] In the description of embodiments disclosed herein, it should be understood that terms such as “comprising” or “having” are intended to indicate the presence of features, numbers, steps, behaviors, components, portions or combinations thereof disclosed herein, and are not intended to exclude the possibility of the presence of one or more other features, numbers, steps, behaviors, components, portions or combinations thereof.

[0062] Unless otherwise stated, " / " means "or". For example, A / B can mean A or B. In this article, "and / or" is merely a way of describing the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0063] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0064] Research has revealed a cloud migration solution for reconstructing application services of cloud platform A on cloud platform B. This solution involves creating a data file mapping relationship between the source cloud host and the target cloud host in the target distributed storage cluster of the target cloud platform; retrieving virtual machine data files from the source distributed storage cluster; and migrating the virtual machine data files to the target distributed storage cluster according to the data file mapping relationship to establish the target cloud host cluster.

[0065] It must be acknowledged that the above solutions can achieve automated cross-cloud application scaling and migration to some extent, but:

[0066] 1) Different clouds have very different implementations of computing, storage, and networking. Directly copying the physical topology required by one application to another cloud may cause problems.

[0067] 2) An application often contains complex sequential dependencies. The above method only provides the final runtime environment of the application, but cannot reflect the dependencies of the application.

[0068] 3) This solution requires the collection of all environmental information, which is extremely complex in production. It needs to collect everything from the configuration information of all virtual machines to a single kernel parameter, which can result in a very long processing time.

[0069] To at least partially address one or more of the aforementioned problems and other potential issues, this disclosure provides at least one cross-cloud application migration solution based on the Open Application Model (OAM). OAM is a standard specification focused on describing applications. With this specification, application descriptions can be completely separated from the details of infrastructure deployment and application management. This solution draws on this characteristic of OAM and designs a standardized application import and export mechanism that can save applications as a medium that is easy to transmit and manage, making application migration more convenient and stable.

[0070] To facilitate understanding of this embodiment, a method for cross-cloud application migration disclosed in this disclosure will first be described in detail. The execution subject of the cross-cloud application migration method provided in this disclosure is generally an electronic device with certain computing power. This electronic device may include, for example, a terminal device, a server, or other processing devices. The terminal device may be a user equipment (UE), a mobile device, a cellular phone, an in-vehicle device, a wearable device, etc.

[0071] In practical applications, considering that the cross-cloud application migration method provided in this disclosure adopts a specific implementation based on the OAM application template, the above method can be implemented based on a separate OAM controller. The following examples will primarily use the OAM controller as the execution entity. Furthermore, in some possible implementations, this cross-cloud application migration method can be implemented by the processor calling computer-readable instructions stored in memory.

[0072] See Figure 1 The diagram shows a flowchart of a cross-cloud application migration method provided in this embodiment of the disclosure. The execution entity of this method can be the OAM controller of this platform. The method includes steps S101 to S102, wherein:

[0073] S101: In response to the target application migration command, obtain the OAM application template corresponding to the target application; the OAM application template is generated based on the component configuration information of the target application;

[0074] S102: Transmit the OAM application template to the first cloud platform; the first cloud platform is used to create the target application based on the received OAM application template.

[0075] To facilitate understanding of the cross-cloud application migration method provided in this disclosure, the application scenarios of the method will be described in detail below. The cross-cloud application migration method provided in this disclosure can be applied to various application scenarios that require cloud migration. For example, it can be migrating an application from a local machine to a cloud platform, or migrating from one platform to another. The migration here mainly refers to the migration of application services and application data. The target application can be any application that needs to be migrated, such as Weibo, UnionPay, etc., without specific limitations.

[0076] Among them, the target application migration instruction can be generated for the target application. In actual application, it can be automatically generated when the platform resources cannot meet the needs of the target application, or it can be initiated by the first cloud platform to which it is to be migrated, or it can be generated under other circumstances. There are no specific restrictions here.

[0077] If a cross-cloud application migration is determined to be necessary, the first step is to obtain the OAM application template corresponding to the target application. Then, the OAM application template is transferred to the first cloud platform. The first cloud platform can be a cloud platform automatically selected based on the need for elastic scaling, or a cloud platform targeted based on specific cloud migration requirements; no specific restrictions are imposed here.

[0078] Upon receiving an OAM application template, the aforementioned first cloud platform can rebuild the target application based on the OAM application template. In the process of rebuilding the target application, in addition to the OAM application template, an image file of the target application is also required. This image file can be obtained locally (i.e., from the first cloud platform), from a pre-built image repository, or received from another cloud platform.

[0079] Regardless of which method the image file is obtained in, the First Cloud Platform can extract relevant application information from the target application's image file according to the OAM application template, and then create the target application based on the application information.

[0080] The OAM application template here is generated based on the component configuration information of the target application. This is mainly because the target application is pre-deployed based on OAM, that is, the target application can be built with the help of the OAM tool.

[0081] OAM, as an application description specification, is based on the core concept of application-centricity. It emphasizes that development and operations should collaborate around a set of declarative, flexible, and extensible upper-level abstractions (YAML files written according to the OAM specification), rather than directly using complex and obscure infrastructure layer application programming interfaces (APIs). After the YAML files written according to the OAM specification are submitted to Kubernetes, the OAM plugin will automatically translate them into complete Deployment and HPA objects to actually run.

[0082] In summary, the target application and the OAM application template are highly correlated. In this embodiment, the target application can be saved as an application template. The OAM controller can package the application information, operation and maintenance information, and topology relationship information between multiple components into an application template.

[0083] During the actual reconstruction of the target application on the First Cloud Platform, in addition to the OAM application template, the image file of the target application is also required. The image file can be owned by the First Cloud Platform itself, received from other cloud platforms, or obtained from an image repository that connects to multiple platforms.

[0084] Here, if it is determined that the target application needs to be migrated, we can first determine whether the target application image file exists on the first cloud platform, and then transfer the OAM application template to the first cloud platform based on the determination result.

[0085] Here, if it is determined that the image file of the target application exists on the first cloud platform, only the OAM application template is transmitted to the first cloud platform; the first cloud platform is used to create the target application based on the OAM application template and the image file of the target application; or, if it is determined that the image file of the target application does not exist on the first cloud platform, the image file of the target application is obtained; the OAM application template and the image file of the target application are transmitted together to the first cloud platform; the first cloud platform is used to create the target application based on the OAM application template and the image file of the target application.

[0086] In practical applications, the existence of the target application's image file on the first cloud platform can be determined based on a single communication between the OAM controller of this platform and the first cloud platform. For example, the target application's identification information can be sent to the first cloud platform. If the first cloud platform finds the target application's image file based on the identification information, it will send feedback to this platform. In this case, if this platform confirms that the target application needs to be migrated, it only needs to transfer the OAM application template to the first cloud platform. If the first cloud platform does not find the target application's image file based on the identification information, it will also send feedback to this platform. At this time, this platform can directly obtain the target application's image file from its local machine, or it can first obtain the target application's image file from a pre-built image repository, and then transfer the OAM application template and the target application's image file together to the first cloud platform.

[0087] In addition, the OAM controller of this platform can also trigger the automatic transfer of image files from the image repository to the First Cloud Platform, without specific restrictions.

[0088] It should be noted that in this embodiment of the disclosure, no judgment is required. That is, regardless of whether the first cloud platform has an image file of the target application, the image file of the target application can be obtained directly from this platform or the image repository, and the OAM application template can be transmitted to the first cloud platform together with the image file.

[0089] In practical applications, due to limitations in transmission bandwidth, if it is determined that an image file exists on the first cloud platform, it is best not to transmit the relevant image file on this platform in order to further improve the timeliness of the migration.

[0090] The image repository in this embodiment serves as a repository platform that interfaces with multiple platforms. It can receive image files uploaded from multiple cloud platforms and send image files to multiple cloud platforms. In practical applications, the functionality of the image repository can be determined based on the needs of various applications. For example, image files of different versions of the same application can be periodically cleaned up; no specific limitations are imposed here.

[0091] In the process of obtaining the image file of the target application from the image repository, the target image information can first be read from the OAM application template, and then the image file matching the target application can be found from the pre-built image repository based on the target image information.

[0092] To facilitate a further understanding of the cross-cloud application migration method provided in the embodiments of this disclosure, the following can be combined with... Figures 2-4 Further examples will be provided.

[0093] like Figure 2As shown, this involves two different Kubernetes clusters. An application, originally deployed on a public cloud platform, now needs to be migrated to a private cloud platform or undergo cross-cloud elastic scaling.

[0094] The following will demonstrate the process of migrating the application to a private cloud platform, such as... Figure 3 As shown.

[0095] Step 1: Save the target application as an application template. The OAM controller packages the application information, operation and maintenance information and topology relationship information between multiple components into an application template.

[0096] Step 2: Export the application template as an image. The OAM controller will then pull the corresponding image from the image repository and package it into an image medium, along with the application template and the image information read from the application template.

[0097] Step 3: The OAM controller pushes the image media to the image repository;

[0098] Step 4: The image repository pushes the image media to the private cloud platform (i.e., the first cloud platform).

[0099] It is known that in practical applications, the OAM application template and the target application image file can be packaged into an image medium and then transmitted to the first cloud platform.

[0100] In this way, the OAM controller of the production cloud platform can export application templates from the image media and create applications from the templates, such as... Figure 4 As shown.

[0101] See Figure 5 The diagram shows a flowchart of a cross-cloud application migration method provided in this embodiment. The execution entity of this method can be the OAM controller of the cloud platform to be migrated. The method includes steps S501 to S502, wherein:

[0102] S501: Obtain the OAM application template sent by the target cloud platform; the OAM application template is generated based on the component configuration information of the target application;

[0103] S502: Create a target application based on the OAM application template.

[0104] Here, if an OAM application template is obtained, a target application can be created based on the OAM application template. Alternatively, if an image file of the target application is obtained, the target application can be reconstructed along with the OAM application template. For the specific creation process, please refer to the description in the above embodiments, which will not be repeated here.

[0105] For information on obtaining the image file, please refer to the description in the above embodiments, which will not be repeated here.

[0106] In the description of this specification, the references to terms such as "some possible implementations," "some implementations," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that implementation or example is included in at least one implementation or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more implementations or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different implementations or examples described in this specification, as well as the features of different implementations or examples.

[0107] Regarding the method flowcharts of embodiments of this disclosure, certain operations are described as different steps performed in a certain order. Such flowcharts are illustrative and not restrictive. Some steps described herein may be grouped together and performed in a single operation, some steps may be divided into multiple sub-steps, and some steps may be performed in an order different from that shown herein. The various steps shown in the flowcharts may be implemented in any way by any circuit structure and / or tangible mechanism (e.g., software running on a computer device, hardware (e.g., logic functions implemented by a processor or chip), and / or any combination thereof).

[0108] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0109] Based on the same inventive concept, this disclosure also provides a cross-cloud application migration apparatus corresponding to the cross-cloud application migration method.
