Abstract:On account of the current situation that existing equipment support can not meet the requirements for full information sharing, reorganization of global resources, flexible supply management and other aspects in IT-based warfare, putting forward the method to build equipment support system based on cloud computing technology, and studying its basic architecture. First of all, discuss the objective and function of equipment support system. Secondly, in the light of the system goal and function, dissect the basic structure of equipment support system based on cloud computing, construct its cloud computing architecture, and explore its security. Finally, build the data mining architecture of this system by analyzing its cloud data center and data stream. This study provides an important reference value for accelerating the information construction of equipment support.
