【Abstract】 Unlike traditional data centers,the management and maintenance of cloud data centers requires solving more complex problems. In order to realize the smooth upgrade and update of big data system in cloud computing platform,a big data migration strategy based on swarm intelligence algorithm is proposed, which effectively solves the problem of load balancing and bandwidth bottleneck. Firstly,the research and analysis of big data migration technology on cloud computing architecture was carried out. Then the artificial fish swarm optimization algorithm was used to solve the optimal solution problem of n data migration between m servers. Finally,the quantum bits were introduced into the artificial fish swarm algorithm to achieve their three basic behaviors. The test results on the Cloudsim simulation platform show that compared with other migration strategies,the proposed algorithm can improve the efficiency of the cloud data center more effectively and has better global optimization ability.更多还原
