A queueing model of an open queueing network with multi-server queues is developed for a cloud computing system and the performance is analysed based on different system parameters such as the arrival and service rates, the number of servers in each node, the routing probability and the number of service types. By using the Laplace-Stieltjes transform (LST) technique, the close-form expression of the Cumulative Distribution Function (CDF) of the total response time is derived. On this basis, some interesting application scenarios are discussed. Detailed numerical evaluations of the developed performance metrics are conducted and simulation results are provided for the application scenario verification. The proposed system modelling and performance analysis method is expected to provide a useful reference for the design and evaluation of cloud computing systems.
