In recent years, enterprises put their products as services to the Internet, but users are not satisfied with a single cloud service. This paper proposes a cloud service composition based on limited range a cuckoo algorithm, aiming to help users choose a high- performance and low-cost cloud service composition according to QoS. Compared with the cuckoo algorithm and other optimization algorithms, the proposed algorithm has better optimization results.

Keywords : QoS; Cloud Service Composition; Cuckoo Algorithm.
