Description

Technical Field

[0001] The present application relates to the technical field of application development and deployment, and in particular to a method, apparatus, medium, computer equipment, and high-performance computer for vehicles for developing and deploying SOA applications based on wasm. Background Art

[0002] Usually, after developing an application (Application, APP), the developer deploys it to the domain controller on the vehicle to run the application on the vehicle. Multiple domain controllers and surrounding resources together form an HPC (High Performance Computer). Currently, the following three solutions are used to implement the above process.

[0003] Solution 1: After the developer completes code development and testing in the cloud, the code is compiled into binary, integrated into the new version of the software, and deployed to the SOC (System On Chip) of the domain controller and runs it. However, in this solution, the process is directly deployed on the host machine, causing invasive damage to the host machine environment. The static deployment and dynamic operation environment of the business on the host machine are intricate, and the business cannot be automatically managed.

[0004] Solution 2: After the developer completes code development and testing in the cloud, the compiled binary is packaged into a docker container. Then the docker container and the docker runtime engine need to be integrated into the new version of the software, and the new version of the software needs to be deployed to the domain controller's SOC and run. However, in this solution, the image is large, the docker runtime engine is also large, the static resources and dynamic running resources required are large, and the many useless functions in the engine also consume resources, which affects the stability / performance of other services and systems of the domain controller, and the performance of starting and stopping is low;

[0005] Solution 3: After the developer completes the code testing in the cloud, the compiled binary is deployed to a lightweight container, and then the lightweight container and lightweight container runtime are integrated into the new version of the software, and the new version of the software is deployed to the SOC of the domain controller and runs. However, in this solution, the image is large, and the lightweight runtime (runtime, such as runc), although much lighter than the docker engine, still occupies more resources and has lower performance such as starting and stopping. Summary of the invention

[0022] In a possible implementation of the first aspect above, the private image repository is open to developers, and the public image repository is open to users.

[0023] In a possible implementation of the first aspect above, the image repository is a wasm binary storage repository, and the wasm image is in a wasm binary format.

[0045] The illustrative embodiments of the present application include but are not limited to methods, apparatuses, media, and computer devices for developing and deploying SOA applications based on wasm.

[0046] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0047] The embodiments of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0048] First, the professional terms involved in this application are explained.

[0049] SOA (Service-Oriented Architecture) is a concept proposed by Gartner in 1996. It is a component model that splits different functional units of an application (called services) and connects them through well-defined interfaces and protocols. The interface is defined in a neutral way to make the software flexible and able to respond quickly to business needs, so that developers can respond to iterative and changing needs with minimal software changes.

[0050] SOA atomic services are services with the smallest granularity. For example, for body control services, atomic services can be designed based on different actuators (electric doors, electric windows, electric door locks, etc.), or based on different sensors (door status switches, window position sensors, door lock status switches). SOA composite services are services that combine multiple atomic services.

[0051] Wasm stands for WebAssembly, a technical solution that allows code to be written in non-Java programming languages ​​and run on browsers. Wasm is a portable, small, fast-loading, and web-compatible format. Wasm is a coding method that can run in modern web browsers, has a compact binary format, can run at near-native performance, and provides a compilation target for languages ​​such as C / C++ / Rust so that they can run on the web.

[0052] However, there is currently no solution to combine wasm and SOA.

[0053] Figure 1According to an embodiment of the present application, a schematic diagram of an application scenario of developing and deploying SOA applications based on wasm is shown. Figure 1 As shown, the cloud server 100 communicates with the HPC 200 on the vehicle. The cloud server 100 includes a development and testing environment 101, an image repository 102, and a control center 103. The image repository 102 is, for example, a wasm image repository 102, and the control center 103 is, for example, a wasm image control center 103.

[0054] The development and testing environment 101 includes a development environment 1011, a test environment 1012, and a quasi-production environment 1013. The image repository 102 includes a private image repository 1021, a public image repository 1022, and a storage 1023. The control center 103 includes a database 1031, and the control center 103 can receive user instructions sent by the user via the terminal device 300, including installation, uninstallation, update, search, deletion, marking, data analysis, etc. The HPC (high performance computer) 200 includes a wasm engine 201, and can also include: body HPC and / or cockpit HPC, etc.

[0055] Figure 2a It is a flowchart of a method for developing and deploying SOA applications based on wasm according to an embodiment of the present invention.

[0056] like Figure 2a As shown, in the development and testing step S21, the SOA application is developed and tested based on wasm to obtain a wasm image corresponding to the SOA application.

[0057] Figure 2b A specific flow chart of the development and testing step S21 is shown. Figure 2b As shown, in the preparation step S201, an integrated development environment (IDE) supporting wasm is defined, the SOA atomic services and composite services open to high-performance computers are converted into wasm dynamic libraries, a coding language is selected based on the SOA atomic services and composite services, and a compiler corresponding to the coding language and supporting wasm is installed.

[0058] An integrated development environment is an application used to provide a program development environment, generally including tools such as code editors, compilers, debuggers, and graphical user interfaces. This integrated development environment supports wasm development and compilation.

[0059] HPC200 has open SOA atomic services and composite services to convert SOA atomic services and composite services into wasm dynamic libraries. Wasm dynamic libraries are libraries in binary format.

[0060] Wasm supports multiple coding languages, including but not limited to C / C++, rust, go, Python, etc. Figure 3 As shown. Based on SOA atomic services and composite services, developers can choose one from a variety of coding languages, for example, the selected coding language is Go language.

[0061] Each coding language has a corresponding compiler. After selecting the go language, install the compiler that corresponds to the go language and supports wasm.

[0062] In the integration step S202, the wasm dynamic library is integrated into the integrated development environment.

[0063] Next, in the encoding step S203, the SOA application is encoded in an integrated development environment using a coding language based on the wasm dynamic library.

[0064] For example, developers can use the Go language to code SOA applications in an integrated development environment based on the wasm dynamic library. In other words, use the Go language to develop a new SOA application in an integrated development environment based on the wasm dynamic library.

[0065] In the compilation step S204, the compiler is used to compile the encoded SOA application to obtain an initial wasm image. Specifically, the compiler compiles the new SOA application to obtain an initial wasm image corresponding to the SOA application. It can be understood that the initial wasm image is in binary format.

[0066] In the test step S205, the initial wasm image is tested to obtain the final wasm image.

[0067] It is understandable that the above steps S201-S204 can be Figure 1 The development environment 1011 is shown. It can be understood that the test step S205 is performed in the test environment 1012 and the quasi-production environment 1013. The initial wasm image obtained by development needs to be tested in the test environment 1012, and then the quasi-production test is performed in the quasi-production environment 1013 to obtain the final wasm image, and then proceed to the subsequent steps. The specific test and quasi-production test methods are the same as those in the prior art, so they are not described in detail here.

[0068] In the sending and authenticating step S22, the wasm image is sent to the image repository 102 and authenticated.

[0069] Specifically, Figure 1As shown, the image warehouse 102 is defined as a wasm binary storage warehouse, which is divided into a public image warehouse 1022 and a private image warehouse 1021. The public image warehouse 1022 is used to store wasm images that have been certified by the original equipment manufacturer (OEM), and the private image warehouse 1021 is used to store unreleased wasm images that have not been certified by the OEM and are still in the development and testing stage.

[0070] The private image repository 1021 is only open to developers, and the public image repository 1022 is maintained by the OEM and open to users (all car owners).

[0071] Figure 2c A specific flow chart of the sending and authentication steps is shown, such as Figure 2c As shown, in S221, the developed and tested wasm image is sent to the private image warehouse 1021 in the image warehouse 102. It can be understood that the user cannot obtain the wasm image in the private image warehouse 1021.

[0072] At S222, the wasm image in the private image repository is authenticated according to the standard customized by the original equipment manufacturer.

[0073] Specifically, the wasm image in the private image warehouse 1021 is authenticated according to the standard customized by the original equipment manufacturer (OEM). The customized standard can refer to offline real vehicle testing, pile driving testing, and online inspection. After the certification is passed, the wasm image in the private image warehouse 1021 is labeled, indicating that it can be recommended to users for a small range of trials, and indexed to the public image warehouse 1022 for promotion and trial. For wasm images that have been tried by a certain number of users and have good feedback, they can be approved for upgrade to the public image warehouse 1022, that is, they are sent to the public image warehouse 1022, so that they can be opened to car owners.

[0074] In S223 , the authenticated wasm image is sent to the public image repository 1022 . It is understandable that users (all car owners) can obtain the wasm image in the public image repository 1022 .

[0075] In the deployment step S23, according to the user's instructions, the wasm image in the public image repository is sent to a high-performance computer for deployment.

[0076] Specifically, the user may send a user instruction to the control center 103 through the terminal device 300 communicating with the control center 103, and the user instruction may be, for example, an installation instruction, an update instruction, an uninstallation instruction, a data analysis instruction, etc. In this embodiment, for example, the user instruction is an installation instruction for installing a SOA application.

[0077] After receiving the installation instruction through the control center 103, the control center 103 obtains the wasm image from the public image warehouse 1022 and sends it to the wasm engine 201 in the HPC 200. The wasm engine 201 uses the wasm image to deploy the SOA application, that is, the wasm engine 201 uses the wasm image to install the SOA application. In this way, the SOA application (wasm application) is installed in the SOC (system on chip) in the HPC 200.

[0078] After the deployment (eg, installation) is successful, the control center 103 receives the installation status from the wasm engine 201 and updates it in the database 1031 .

[0079] It is understandable that the private image repository 1021 and the public image repository 1022 can store multiple different wasm images, each of which corresponds to a SOA application. According to user instructions, the corresponding wasm image can be deployed in the SOC.

[0080] like Figure 1 As shown, the control center 103 communicates with the image manager 301 , and the image manager 301 can perform daily maintenance on all wasm images in the image warehouse 102 through the control center 103 .

[0081] Figure 3 FIG. 2 shows a structural diagram of a wasm engine 201 according to an embodiment of the present invention. Figure 3 As shown, the wasm engine 201 includes a wasm orchestration module 2011, a wasm lifecycle management module 2012, a wasm execution module 2013, and a wasm runtime management module 2014.

[0082] The wasm orchestration module 2011 communicates with the cloud server 100 and receives the wasm image to be deployed.

[0083] Specifically, the wasm orchestration module 2011 is responsible for communicating and interacting with the control center 103 in the cloud server 100. When deployment is to be performed according to user instructions, the control center 103 pulls out the wasm image corresponding to the user instruction from the public image repository 1022 and sends it to the wasm orchestration module 2011. The wasm orchestration module 2011 receives the wasm image and transmits it to the wasm lifecycle management module 2012. In this embodiment, the wasm image is obtained according to the method described above.

[0084] The wasm lifecycle management module 2022 manages the wasm image throughout its lifecycle.

[0085] Specifically, the wasm lifecycle management module 2012 uses systemd (system daemon, which is an init software under Linux) or other management software to manage the wasm image throughout its life cycle, and transmits the wasm image to the wasm execution module 2013.

[0086] The wasm execution module 2013 determines the operation interface corresponding to the wasm image, namely the runtime, based on the wasm image, and then calls the corresponding runtime from the wasm runtime management module 2014 and executes the corresponding runtime, thereby deploying the wasm image on the SOC (system-on-chip) to form a wasm application.

[0087] The wasm runtime management module 2014 is used to manage multiple operation interfaces. The wasm runtime management module 2014 is responsible for encapsulating multiple operation interfaces of the operating system for calling by the wasm execution module 2013. It can be understood that these operation interfaces are wasm binary operation interfaces, such as create, stop, restart, etc.

[0088] In addition, when the user issues a data analysis instruction, the SOA gateway on the HPC 200 will collect the running data of the SOA application on the vehicle, including the application running status, user habits, etc. The running data is then uploaded to the image warehouse 102 for big data analysis.

[0089] In the present invention, SOA applications are developed based on wasm and deployed on vehicles, realizing the DevOps (software development and operation maintenance) process. The present invention uses wasm machine code to carry and run SOA applications, which not only inherits the advantages of containers in DevOps, but also solves the shortcomings of insufficient performance of ordinary containers, so that the start and stop time of wasm applications on the host machine is shortened, the operating resources are reduced, the wasm application image is smaller, and the image transmission time from the cloud server to the vehicle is shortened.

[0090] Furthermore, Wasm supports multiple coding languages, including but not limited to C / C++, rust, and go. This way, SOA application developers are not limited to a certain development language, and have greater flexibility for both existing code logic and new code logic.

[0091] The present invention also provides a device 40 (based on wasm for developing and deploying SOA applications) Figure 4 ), for a cloud server, such as Figure 1 The cloud server 100 is shown. The cloud server 100 includes an image repository 102, and the cloud server 100 communicates with a high performance computer (HPC) 200 on the vehicle.

[0092] like Figure 4 Said device 40 comprises:

[0093] A development and testing unit 401 develops and tests the SOA application based on wasm to obtain a wasm image corresponding to the SOA application;

[0094] A sending and authentication unit 402 sends the wasm image to the image repository and performs authentication;

[0095] The deployment unit 403 sends the authenticated wasm image to the high-performance computer for deployment according to the user instruction.

[0096] It is understandable that the development and testing unit 401, the sending and authentication unit 402, and the deployment unit 403 can be Figure 5 The processor 102 in the computer device 100 having the functions of these modules or units is implemented.

[0097] The present invention also provides a computer-readable storage medium, on which instructions are stored. When the instructions are executed on a computer, the computer executes the method shown in FIG. 2 .

[0098] Reference now Figure 5 , Figure 5 An example computer device 1400 according to an embodiment of the present invention is schematically shown.
