On September 20 12, at the first the State Council-level conference on education informatization held in New China, Comrade Liu Yandong, then State Councilor (now Vice Premier of the State Council), pointed out that the key work of education informatization in the next few years can be summarized as "three links and two platforms", namely "broadband network school-to-school communication, high-quality resources inter-class communication, online learning space for all and public service platform for education management". Broadband network school-to-school communication and high-quality resource class-to-class communication have always been the key work of educational informatization during the Eleventh Five-Year Plan period, and this time it has been given new connotations. Everyone in online learning space is a new concept. Wang Yanjue, director of the Science and Technology Department of the Ministry of Education, believes that everyone is the basic platform for network teaching and network management under information technology in the future, an important guarantee for achieving high-quality resources, and a social network that can achieve specific teaching goals. In Liu Yandong's speech, he put forward two pioneers to promote "everyone is connected", namely "taking the lead in promoting vocational education and teachers". The Ministry of Education explicitly requires 20% of vocational colleges to carry out the application of "Everyone Connect" in 20 13 years.

In 20 13, the Science and Technology Department of the Ministry of Education put forward that the core goal and landmark project of national education informatization during the Twelfth Five-Year Plan period is the "Three Links Project", and its specific goals are: by 20 15, basically realize "broadband network to connect schools"-all kinds of schools at all levels are connected to broadband to build a basic teaching and learning environment under network conditions; Get high-quality resources by class-form rich high-quality digital education resources at all levels, send high-quality resources to every class, and realize universal use in the process of teaching and learning; "Online learning space is accessible to everyone"-all teachers and students above junior high school have online learning space in real-name registration system, and teaching and learning, teaching and teaching, and learning and learning interact in all directions, truly integrating technology and teaching practice into the daily teaching activities and learning activities of each teacher and student.

Under this policy background, many educational information service providers and provincial education departments have developed "Everyone Connected" related products through cloud service technology, such as Hunan Tiantianshang Everyone Connected Cloud Service Platform, World University City, China Unified Education Network, Jiangxi Telecom "Cloud Cube" and so on. All these can provide relevant solutions for the construction of "everyone connected" in the education system.
