Abstract: Following the analysis of cloud computing security in the paper, a framework of security service cloud computing was proposed based on cloud computing service pattern, which provided consistent standard model. Furthermore, the mechanism of the framework was introduced and analyzed, and a deployment algorithm of security service was proposed based on selection of the best computing server. The simulation results show that the proposed algorithm is better than random algorithm in terms of system load balance and service time.
