Abstract: There are some problems in equipment web simulating training, including poor sense of reality, low efficiency of training and high difficulty of management. To solve those problems, Infrastructure as a Service mode “cloud training” was proposed. The architecture and operation flow were explained in detail and the key technologies of “cloud training” were focused on. By GPU virtualization technology, the problem of client 3D image processing capability was solved. According to the characters of simulation training, the user requirement model was established. Fuzzy algorithm was introduced to realize resource dynamic scheduling. To assure the stability and reliability, combined with checkpoint, virtual machine backup and migration, dynamic failure tolerance algorithm was given. The results show that resource-sharing capability and simulating training effect have been improved.

Key words: simulating training, IaaS, cloud training, GPU virtualization, dynamic resource scheduling, dynamic failure tolerance
