In the context of the rapid development of military cloud infrastructure and mobile networks, this paper focuses on the deployment and operation requirements of mobile end training systems for different cloud platforms, aiming to solve the problems of cross-platform deployment and dynamic resource allocation and monitoring of mobile end systems. Based on the analysis of the current status of US military cloud facilities and the domestic commercial mobile application architecture, this paper proposes a multi-cloud integration microservice architecture for single-person training on mobile devices. First, microservice technology is used to decouple and slim down the back-end training services. Second, a multi-cloud integration architecture is used to dynamically adjust and match the optimal cloud resources. Finally, automation technology is used to monitor cloud-end services in real time. Combining the application practice of the system, this architecture provides useful technical reference and methodological support for the development of the next-generation training system.
