Cloud Cloud:
The concept of Yunteiyun is an extension of the concept of "internet Internet", which was first proposed by Kevin Kelly in 2007, and he believes there will eventually be a cloud of clouds, the Yunteiyun. In the 2009, the concept of Yunteiyun became popular and was used to describe future data centers. The Yunteiyun concept is based on the idea that a single cloud cannot include wireless resources, and Yunteiyun can implement the need for services that will be sent to customers to further distribute between the cloud and cloud, enabling each cloud to use virtual infrastructure on other clouds, including computing and storage resources. Yunteiyun takes the form of "pay for use", which brings new opportunities for cloud vendors. At the same time, there are many challenges in the aspects of Yunteiyun, security, interoperability, QoS, supervision and billing.
