Abstract: Cloud environment is a complex and changing environment,to provide different services at different levels,in dealing with the type of service when the service request and the server node is a supply of dynamic,random process of change,and how efficient organization and use of these nodes processing power,that is,the load in the environment,technology should consider.In this paper,the cloud made the private cloud model summarized;and load balancing scheduling problem on different platforms in the description of the relevant research status,and finally,that the load balance scheduling in the private cloud in the direction of future research.
