With the rapid expansion of national colleges and universities, many offices and school districts in colleges and universities are in a very dispersed state. In addition, the amount of teaching management information in colleges and universities is constantly increasing, thus increasing the difficulty of college teaching management. Compared with the traditional configuration of software, hardware and stand-alone mode, cloud computing mode has obvious advantages. In the process of providing network services, the functions of software and hardware can be brought into full play. Through this technology, user terminals can also be transformed into interactive tools in cloud networks, so that some functions that can only be run on large hosts can be realized with the help of user terminals. In this paper, the design and implementation of the application system based on cloud platform are studied for the college teaching management system. The cloud platform model is designed on the basis of multiple computer resources, which greatly improves the computing function and storage function of the management application platform.
