In order to meet the increasing training requirements of our military’s flight simulation training, a cloud computing-based flight simulation training architecture is designed. According to the characteristics of cloud computing, the concept of service-oriented flight simulation cloud is proposed, and the flight simulation training architecture is constructed basing on ultra-high performance network. The traditional simulation technology is used to design while applying the technique of distributed computing, distributed storage, distributed cache, data synchronization and spatial coherency. Then the advantages of the system are compared and analyzed. The results show that the system can realize high availability of flight simulation training resources, achieving reliable calculation and data storage of each simulator’s subsystem.
