Abstract
The invention relates to a workflow scheduling method taking communication and computing costs into account under a multi-cloud environment. On the basis of the structure and execution characters of the workflow, related factors of the communication of the current cloud resource environment and execution costs, random two-point interlace operation of a genetic algorithm and a random single-point mutation operation idea, the method improves diversity in the population evolution process, integrates virtual resources, takes into account data communication costs and assignment computing costs, optimizes a resource utilization rate and reduces the execution costs on the premise of satisfying the workflow expiration date. According to the method, under the situation that fluctuation factors exist, great property performance can be achieved in the aspects of satisfying the workflow expiration date and executing cost control, and on the premise of satisfying the workflow expiration date as much as possible, the execution costs are reduced.
