[0002] As the demand for software development grows day by day, the traditional development methods are complex in code writing and have a long development cycle, resulting in low development efficiency.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] In one embodiment, Figure 1 As shown, an application deployment method is provided. This embodiment uses the method applied to a terminal as an example. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0039] Step 102, obtaining deployment information; the deployment information includes configuration information and resource requirement information.

[0040] Deployment information refers to all the information that needs to be collected and parsed before the application is deployed to ensure that the application can run correctly in the target environment. The acquisition of deployment information usually relies on configuration files, databases, APIs, and dynamic requests from the management platform to ensure the accuracy and timeliness of the information.

[0041] Deployment information includes configuration information and resource requirement information. Configuration information refers to detailed parameters related to the operating environment, functions, dependencies, etc. of the application instance. Configuration information is used to ensure that the application has the correct environment configuration when it starts, including system-level configuration, network configuration, dependent services, port numbers, etc. For example, an application instance may need to rely on a specific version of a database or external API service, and the configuration information clarifies these requirements. Resource requirement information refers to the computing resources, storage requirements, network bandwidth, and other external resources required by the application instance during runtime. Resource requirement information is used to provide sufficient resource support for the application instance to ensure that the application can run normally and will not cause bottlenecks due to insufficient resources. For example, an instance may require a high memory configuration to process big data tasks, while another instance may require high network bandwidth for a large number of network interactions.

[0042] For example, in the scenario of a low-code platform, assume that the user is deploying a Customer Relationship Management System (CRM) application. Configuration information may include the service port number, database connection information, API interface configuration, user authentication method, etc. required by the application instance. For example, the application may need to access an external user data API and synchronize data with the database inside the platform, so the configuration information will specify the database connection parameters, API access rights and URL address, etc. Resource requirement information includes the resources required by the application instance at runtime, such as the number of CPU cores, memory capacity, storage space, and network bandwidth for each CRM module to process data. For example, the customer data module of the CRM system may require higher memory and processing power to process large amounts of user data, while the data synchronization module may require higher network bandwidth for frequent data exchanges with external APIs.

[0043] Step 104: Initialize multiple application instances according to the configuration information, and allocate application resources to each application instance according to the resource demand information.

[0044] Among them, an application instance refers to a separate entity created by the platform and running in a virtualized or containerized environment according to configuration requirements. Each application instance is an independent unit with independent functions and resources, which can be dynamically started and run according to configuration information and resource demand information. For example, in a low-code platform, each application instance may represent a specific module or function, which can work independently or in collaboration with other instances.

[0045] Optionally, the process package for initializing multiple application instances starts the required application instances according to the configuration information. Each instance is initialized according to the module definition, interface requirements, and external service links in the configuration information. For example, if an instance needs to communicate with an external database, the application instance will automatically configure the database connection and authentication information during the initialization process to ensure that the relevant data can be accessed normally.

[0046] Optionally, the specific process of allocating application resources to application instances based on resource demand information includes dynamically allocating computing resources, memory, storage, and network bandwidth based on the resource demand of each application instance. For example, a certain instance may require more memory and storage to process data analysis tasks, while another instance may only require smaller computing resources. The system automatically allocates resources based on these demands to avoid resource waste and ensure efficient operation of each application instance.

[0047] Step 106: configure a message queue for each application instance so that each application instance can communicate asynchronously through application resources.

[0048] Among them, message queue refers to a communication mechanism that allows application instances to exchange data through message passing, usually in an asynchronous manner. Through message queues, application instances can asynchronously transmit data in different threads or processes, avoiding direct synchronous calls, reducing system load, and improving system responsiveness and scalability.

[0049] Optionally, configuring a message queue for an application instance includes creating or configuring a message queue service, such as Kafka, RabbitMQ, etc., to ensure that each application instance can communicate with other instances or external services. The system allocates one or more message queues to each application instance and configures them based on the communication needs of the instance. For example, some instances may need to handle high-frequency messaging, while others may need to handle low-frequency batch data.

[0050] For example, the process of how application instances communicate asynchronously is as follows: when an application instance needs to send data to another instance, it packages the data into a message and sends it to the message queue. The receiving application instance then obtains the data from the message queue and processes it. Due to asynchronous communication, the sender does not need to wait for the receiver's response, which can process a large number of requests in a short time and ensure high throughput of the system. In this way, the platform can achieve loosely coupled asynchronous interaction between multiple application instances, improving the overall efficiency and scalability of the system.

[0051] In the above application deployment method, first, configuration information and resource requirement information are obtained, then multiple application instances are initialized according to the configuration information, and the required resources are dynamically configured for each instance according to the resource requirement information, so that resource waste can be avoided and resource utilization can be improved. After that, a message queue is configured for each application instance, so that application instances can interact through asynchronous communication, reducing the coupling between applications, improving the flexibility and scalability of the system, and thus improving the maintenance efficiency of the system.

[0052] Further, in one embodiment, the above deployment information includes message queue information; configuring a message queue for each application instance includes: creating a message queue corresponding to each application instance according to the message queue information; the message queue is used to process asynchronous requests; and associating each application instance with the corresponding message queue.

[0053] The message queue information refers to the configuration related to each application instance to ensure that they can communicate through the asynchronous message queue. The queue information includes the queue type, queue name, message transmission protocol, queue storage strategy, access control rules, etc.

[0054] Optionally, based on the message queue information, the system will create a corresponding message queue for each application instance. The specific process includes creating a message queue through an API interface using message queue technology, such as RabbitMQ, Kafka, or ActiveMQ, based on the queue definition in the configuration file or database. The creation process generally reads the message queue information first, including the name of the queue, message storage strategy, etc., and then uses the interface call of the message queue technology to create the queue. For example, when using RabbitMQ, the system declares the queue by calling the channel.queueDeclare method, specifying the queue name, persistence properties, and other related parameters. If the queue already exists, skip the creation process and use the existing queue directly; if it does not exist, create a new queue.

[0055] Optionally, after creating the message queue, the system will associate each application instance with its corresponding message queue. First, the system assigns a unique identifier to each application instance, and then binds each instance to the corresponding message queue by reading the configuration file of the message queue or using the API interface. Furthermore, the technical implementation of the association process depends on the connection management component of the message queue. For example, in RabbitMQ, instances and queues are bound through Channel.basicConsume and Channel.basicPublish to ensure that each instance can send and receive messages through the corresponding queue. Among them, Channel.basicConsume is used for operations that receive messages and Channel.basicPublish is used for operations that send messages.

[0056] In this way, the configuration and creation of message queues enable each application instance to process tasks independently and flexibly. The message queue provides an efficient asynchronous communication mechanism by decoupling the dependencies between different application instances.

[0057] Furthermore, in one embodiment, after allocating application resources to each application instance according to the resource demand information, the method further includes: monitoring the configuration information and resource demand information through a pre-set application listener; when it is detected that the resource demand information and the configuration information are modified, generating adjustment resource information and adjustment configuration information, and reconfiguring the application instance according to the adjustment configuration information, and allocating new application resources to the reconfigured application instance according to the adjustment resource information.

[0058] Adjusting resource information means that the resource configuration of the application instance has changed, including the difference between the original configuration and the current configuration. For example, if the originally allocated memory is 2GB and the adjusted resource requirement is 4GB, then the adjusted resource information is the change in memory resource requirement, that is, the 2GB difference. Adjusting configuration information means that the configuration parameters of the application instance have changed, such as the version number of the application, execution parameters, or the path of the configuration file have been modified. Adjusting configuration information reflects the system's adjustment or optimization of the configuration content.

[0059] An application listener is a monitoring tool or mechanism that is designed to track and respond to changes in resource requirements or configurations in the system in real time. The listener is usually pre-set by registering callback functions, event monitoring, or polling, and continuously monitors changes in resource or configuration information. Once changes in resource requirement information or configuration information are detected, the listener triggers corresponding operations, such as generating and adjusting resource information, adjusting configuration information, and performing subsequent processing. The listener can be set up through a configuration file, such as loading a configuration file at system startup, or adjusting the configuration through a background management tool.

[0060] Exemplarily, the application listener can monitor the resource demand or configuration information status by periodically polling, or by a system event trigger mechanism. For example, in the resource monitoring module, when the CPU usage or memory usage exceeds a preset threshold, the listener will automatically trigger, generate adjustment resource information and reallocate.

[0061] Furthermore, in order to improve the real-time performance and efficiency of monitoring, a scheduled task may be set to periodically check the status of resource requirements and configuration information, and perform monitoring operations through a scheduling mechanism.

[0062] Optionally, you can use the PowerJob framework to register `appName` for the application group and create a scheduled task. PowerJob is an efficient and scalable distributed task scheduling framework that can easily create scheduled tasks for application instances or application groups and perform task scheduling. With PowerJob, you can create scheduled tasks to regularly check whether the resource requirements and configuration information of the application instance have changed, and trigger related monitoring operations when necessary.

[0063] For example, in the PowerJob framework, a unique identifier (such as appName) can be registered for an application instance group. This identifier is used to distinguish different application groups or instances and create corresponding task schedules for each application instance. PowerJob can be used to create scheduled tasks for application groups or application instances. For example, a scheduled task can be set to check changes in resource requirements and configuration information at regular intervals. If changes are detected, a monitoring operation is triggered to reconfigure the application instance or update resource requirements.

[0064] Among them, it is possible to judge whether the resource demand information or configuration information has been modified by comparing the difference between the historical configuration and the current configuration. For example, the current resource configuration can be compared with the configuration before the modification. If a difference is found, it can be determined that the information has been modified. The process of determining the modification usually relies on a configuration management tool or a version control system, or triggers the modification judgment by monitoring the real-time changes of the data source.

[0065] Afterwards, the application instance is reconfigured according to the adjusted configuration information, and new application resources are allocated to the reconfigured application instance according to the adjusted resource information.

[0066] Among them, reconfiguring the application instance according to the adjustment configuration information includes: verifying the validity of the adjustment resource information and the adjustment configuration information; sending the adjustment configuration information to each application instance by broadcasting when the validity verification passes; and updating the configuration of each application instance according to the adjustment configuration information.

[0067] Validation refers to ensuring that the adjusted resource configuration and configuration information meet the actual needs of the system and do not cause inconsistencies or conflicts. For example, the system needs to verify whether the new resource requirements can meet the conditions of the existing hardware environment, or whether the new configuration information meets the expected behavior of the application instance.

[0068] Optionally, the validity verification process can be performed by an automated verification tool, which will check the compatibility of the new resource configuration with the current environment, such as checking whether the allocation of memory, CPU, and storage is within a reasonable range, and confirming whether the format, type, and content of the configuration information meet the specifications. After the verification is passed, the system will continue with the subsequent configuration update, otherwise an error log will be generated and the update process will be stopped.

[0069] Furthermore, when the validity verification of the adjustment resource information and configuration information is passed, the system will send the adjustment configuration information to each application instance by broadcasting. The broadcast method can ensure that all relevant application instances receive the configuration information update at the same time, avoiding the delay and synchronization problems caused by pushing one by one. After receiving the adjustment configuration information, each application instance will automatically update according to the new configuration, which may include reloading the configuration file, adjusting resource allocation, restarting the application service, etc. Transmitting configuration information by broadcasting can ensure that each application instance in the system is updated synchronously at the same time point, ensuring the consistency and stability of the system.

[0070] In one embodiment, after the application instance is reconfigured according to the adjustment configuration information, the method further includes: detecting whether the adjustment configuration information is effective according to a preset time interval; if the adjustment configuration information is not effective, reconfiguring the application instance according to the adjustment configuration information until the adjustment configuration information is effective.

[0071] The system monitors the status of the application instance through periodic checks to confirm whether the adjusted configuration information has been successfully applied. If the configuration of the application instance does not change as expected within the set time, the system will determine that the adjusted configuration information has not yet taken effect. In order to ensure the correctness of the system configuration, the system will reconfigure the application instance according to the adjusted configuration information. This process will continue until the adjusted configuration information is fully effective.

[0072] Exemplarily, the system compares the configurations of each application instance at preset time intervals. Once it detects that the adjusted configuration information is not effective, the system automatically initiates a reconfiguration operation, applies the adjusted configuration information to the application instance again, and continues to detect whether the adjusted configuration information is effective.

[0073] This ensures that configuration updates in the system will not fail to take effect in a timely manner due to occasional errors or network problems.

[0074] In one embodiment, after generating multiple application instances according to the configuration information, the method further includes: generating an application identifier for each application instance, and returning the application identifier to the front end; the application identifier is used to modify the configuration information and resource requirement information.

[0075] The application identifier is a unique identifier used to uniquely identify each application instance. The identifier can be a unique string automatically generated by the system, or generated by certain attributes in the configuration information, such as the application name and version number. After the system generates application identifiers for each application instance, it associates these identifiers with the corresponding application instance and returns them to the user through the front-end interface. In this way, the user can view the identifiers of each application instance through the front-end interface and configure and manage the corresponding application instance based on the identifiers.

[0076] For example, the appId of each application instance can be accurately obtained by implementing the getAppId method in the ApaasSingleAppProperties class. This method returns a unique application identifier when the application instance is initialized. This identifier is not repeatable in the system and can ensure accurate tracking and operation of each application instance. In asynchronous logic, the getAppId method can be used to asynchronously obtain and process the appId. For example, when the application instance is configuring resources or modifying configuration information, the method can be asynchronously called to accurately identify which application instance is currently being operated. In this way, the accuracy and consistency of the appId can be ensured regardless of synchronous or asynchronous operation.

[0077] For example, users can select and configure the deployment information corresponding to each application instance through the application identifier in the front end. Users can modify the configuration information or resource requirement information of each application instance according to the application identifier of each application instance, such as adjusting the memory, CPU or storage capacity. In this way, the system can accurately identify each application instance and allow users to flexibly manage and modify the configuration and resource allocation of different application instances, thereby achieving more efficient resource management and deployment optimization.

[0078] In an exemplary embodiment, in combination Figure 2 , Figure 2 A flowchart of the steps of application deployment in one embodiment.

[0079] Step S202: Obtain deployment information, wherein the deployment information includes configuration information and resource requirement information.

[0080] Step S204, initialize multiple application instances according to the configuration information, and allocate application resources to each application instance according to the resource demand information. After initializing each application instance, it also includes generating an application identifier for each application instance and returning the application identifier to the front end; the application identifier is used to modify the configuration information and resource demand information.

[0081] Step S206, configure a message queue for each application instance so that each application instance can communicate asynchronously through application resources. The deployment information includes message queue information; configuring a message queue for each application instance includes: creating a message queue corresponding to each application instance according to the message queue information; the message queue is used to process asynchronous requests; and associating each application instance with the corresponding message queue.

[0082] Step S208, monitor the configuration information and resource demand information through a pre-set application monitor; when it is monitored that the resource demand information and configuration information are modified, generate adjustment resource information and adjustment configuration information, reconfigure the application instance according to the adjustment configuration information, and allocate new application resources to the reconfigured application instance according to the adjustment resource information. Reconfiguring the application instance according to the adjustment configuration information includes: validating the adjustment resource information and the adjustment configuration information; in the case of passing the validity verification, sending the adjustment configuration information to each application instance by broadcasting; each application instance updates the configuration according to the adjustment configuration information.

[0083] Step S210, detecting whether the adjusted configuration information is effective according to a preset time interval; if the adjusted configuration information is not effective, reconfiguring the application instance according to the adjusted configuration information until the adjusted configuration information is effective.

[0084] In yet another exemplary embodiment, in combination Figure 3 As shown, Figure 3 The diagram is a containerized deployment diagram of an aPaaS platform and a Kubernetes (K8S) cluster in one embodiment.

[0085] Among them, the aPaaS operation and maintenance management platform includes multiple container components, including Container aPaaS components, Container RabbitMQ components, Container Redis components, Container MySQL components, Container MongoDB components and Container PowerJob components. Container aPaaS components are used to manage and coordinate containerized applications, Container RabbitMQ is responsible for message queue functions and supports asynchronous communication, Container MySQL is used for persistent data storage, Container MongoDB is used for unstructured data storage, and Container PowerJob is a task scheduling component used for the management and execution of scheduled tasks or distributed tasks. Among them, the K8S cluster is the core of container orchestration and scheduling and is responsible for service deployment. The Jenkins service is responsible for the pipeline management of the application release process. Jenkins deploys applications from the development stage to the application operating environment in the K8S cluster through the CI / CD (continuous integration and continuous deployment) pipeline.

[0086] In this embodiment, each container can identify an application instance, and each application instance performs resource configuration and management through the core functions of Kubernetes.

[0087] exist Figure 3 The process of application deployment in aPaaS includes: 1. The user submits an application deployment request through the aPaaS operation and maintenance management platform. The deployment request carries deployment information. The platform generates multiple application instances based on the configuration information and resource demand information submitted by the user, and assigns a corresponding identifier to each instance; 2. The platform dynamically allocates computing resources and related configurations to application instances through interaction with the K8S cluster; 3. RabbitMQ provides asynchronous communication capabilities between application instances to ensure loose coupling between services; 4. The Jenkins service packages and pushes the application to the K8S cluster according to the configured pipeline process. K8S is responsible for deploying the application to the target environment; 5. After the deployment is completed, the application instance is exposed to the outside through the services provided by K8S. Redis and MongoDB provide data support, and the K8S cluster monitors the running status of the application. If there is a need for resource or configuration adjustment, PowerJob can reschedule the task and the Redis cache can be refreshed dynamically.
