[0188] The infrastructure layer is a key component for supporting and managing aerospace equipment simulation systems. It provides the necessary infrastructure and tools to support the development, deployment, monitoring and management of aerospace equipment simulation training systems.

[0189] Service registration and discovery module: Services in the application service layer and domain service layer in the microservice architecture need to register their network information and availability information with the service registration and discovery module, so that other services can discover and identify available services by querying the service registry in this module; when multiple instances or copies of the same service are available, the service registration and discovery module can distribute requests to different instances according to the preset load balancing algorithm to achieve load balancing; the service registration and discovery module can regularly or periodically detect the health status of registered services, and determine which instances are available, which instances have failed or are unavailable by regularly sending heartbeat or health check requests. It provides a mechanism for dynamic management and discovery of services, allowing services to collaborate with each other, expand elastically, and achieve load balancing, thereby building a reliable and scalable distributed system.

[0190] The registration center module is used to register network information and availability information of each service in the aerospace equipment simulation system, and regularly sends heartbeat or health check requests to determine the availability status of each service.

[0191] The load balancing module is used to improve the concurrency and scalability of the aerospace equipment simulation system, and to improve the system's response speed and performance.

[0192] The configuration center module stores configuration information in one place instead of distributing it in various services at each layer, making configuration management more convenient and centralized. Administrators can centrally manage and update configurations without modifying the configuration files of each microservice one by one; the configuration center supports dynamic configuration updates without restarting the service, which means that configuration information can be modified at runtime and the configuration will take effect immediately. Such updates allow microservices to adapt more flexibly to changes in the environment and business requirements; the configuration center module supports version control of configurations. Through version control, the change history of configurations can be tracked and managed, and after errors occur due to changes in configuration files, you can roll back to the previous configuration version; the configuration center also provides configuration security and permission management functions to ensure the security of sensitive configuration information. The configuration center module can easily obtain and manage configuration information, and realize centralized management, dynamic updates and version control of configurations. This makes the microservice architecture more flexible, maintainable and scalable.

[0193] The logging module is used to uniformly collect, record and visualize the log information of the aerospace equipment simulation system. The recorded information involves detailed information about the system status, exceptions, errors and warnings. When an error occurs, the root cause of the problem can be determined by analyzing and checking the logs, and appropriate measures can be taken to repair it. The logging module can also record some key performance indicators and measurement data, such as request response time, resource utilization, and communication delays between services. These log data can be used for performance detection and optimization, helping developers understand performance bottlenecks and the causes of bottlenecks, and take appropriate measures to improve performance and scalability. The logging module provides a key source of information to help the team quickly locate and solve problems, and provide valuable insights for the continuous improvement of the system.

[0194] The link tracking module is used to track the call path and flow in the aerospace equipment simulation system, and supports the performance and exception analysis of the service. It can track the complete path and flow of a request in the system, and turn the request in the system into a complete link diagram; the link tracking module can capture and record performance data during the request processing, such as the processing time of the request, the communication delay between services, etc., and can identify performance bottlenecks and the services where the bottlenecks are located. It helps to locate and solve performance problems in the system, optimize the performance of the service call chain, and improve the response time and throughput of the overall system; the link tracking module can capture and record exceptions that occur during request processing, and can track the location and service where the exception occurs, quickly locate and solve problems, and provide system reliability and recoverability. The link tracking module allows developers to better understand and manage the flow and call relationships of requests in microservice systems, and improve the reliability and maintainability of the system.
