摘　　要：为了满足用户和云服务提供商的不同需求,如何高效进行混合云科学工作流调度成为急待解决的难题。考虑到科学工作流任务间通信量大、公有云安全性等特性,提出基于费用感知和安全感知的混合云科学工作流调度(Hybrid cloud Cost and Security-aware Workflow Scheduling,HCSWS)算法。实验表明,相比混合云优化成本(Hybrid Cloud Optimization Cost,HCOC)算法,HCSWS算法在保证安全性前提下能有效降低公有云费用和提高执行效率。How to schedule scientific workflow efficiently in hybrid cloud for the different needs of users and cloud service providers has become an urgent problem to be solved.Considering the characteristics of large communication between scientific workflow tasks and public cloud security,a Hybrid cloud Cost and Security-aware Workflow Scheduling(HCSWS)algorithm is proposed.We present extensive experimental and simulation results which show that compared with Hybrid Cloud Optimization Cost(HCOC),HCSWS can reduce cost and increase efficiency while ensuring security.
