With the promotion of the triple?net fusion,the mass VOD emerges out some characteristics such as complicat?ing data,multiple platforms and huge business,which make a huge challenge to the traditional on?demand mode. By using the powerful computing ability and mass data efficient processing of cloud computation,the application of cloud computation in mass VOD system is discussed on the basis of analysis of the basic framework and technical characteristics of cloud computation and in combination with the characteristics of VOD service. The framework and working principle of the cloud computing system are analyzed. Some main technologies,such as redundancy backup of data,heartbeat detection,replacement of intelligent nodes and load balancing are elaborated. A new idea to make the mass video propagation smooth is put forward.
