Two cloud computing bases were set up in Ningxia Hui autonomous region on Monday in cooperation with leading Web service operators worldwide to tap into the city's geology, climate and energy advantages.

West Cloud Valley has contracted with Amazon Web Service and will host 200,000 servers for cloud computing, said Li Jiang, director general of the base.

It will be the first project in which US giant Amazon, which has the largest scale of operations in the world, is officially working with a Chinese cloud base, according to officials of Zhongwei, where the bases are located.
