Digital infrastructure for public services is the “road, railway, and bridge” of the digital world.

Specifically, public service digital infrastructure includes cloud computing infrastructure (“strong foundation”) and network infrastructure (“road paving”).For national ICT construction departments and informatization companies, such as the Ministry of Communications and the Ministry of Digital Development, based on leading technology and extensive industry experience, Huawei has launched three scenario-based solutions in terms of national cloud and network infrastructure, which helps customers build national digital infrastructure and achieve comprehensive national informatization.
