Large Scale Distributed Information System Emulation Platform Based on Cloud Computing Technology

Because of wide area deployment, large number of system nodes, and other characteristics of large scale distributed information systems, the system evaluation and testing are more difficult than traditional ones. In this paper, we summarize the requirements of large scale distributed information system evaluation and testing tasks, based on Open Stack architecture and virtualization technology, discuss the mechanism of constructing large scale distributed information system running environment, establish a prototype system and carried out a serious of simulation experiments to verify the feasibility of the proposed mechanism.
