Aiming at the problem of low sharing efficiency of teaching resources and limited sharing scope of traditional teaching platforms, this paper first designs a digital English teaching resource sharing platform through cloud computing technology. After that, the cloud platform resource structure, educational application services and other modules are refined, and the authentication framework is constructed to realize the safe sharing of data. The results show that the remote classroom teaching method of English teaching resource sharing based on cloud computing demonstrates significant advantages. In addition, the platform not only plays a stable role in resource sharing efficiency, but also has high efficiency, which is highly practical and effective. The English teaching resource sharing and remote classroom platform proposed in this paper is applied to English classroom teaching in colleges and universities, which can stimulate students’ learning initiative, improve students’ learning efficiency, and comprehensively enhance students’ interest in learning English.
