Abstract: The resource scheduling problem in cloud computing environment is discussed. According to the characteristics of the cloud computing environment, the tasks structure and the  node failure, a mathematical resource scheduling model is established. The discrete particle swarm algorithm is used to solve the problem. The simulation test example is created according to the facts of the cloud computing service operation and the verification shows that the model is rational and the algorithm is feasible and effective.
