混合云中基于截止时间和费用约束的调度方法研究
Resource scheduling methods based on deadline and cost constraint in hybrid cloud
摘要
Abstract
In hybrid clouds,private clouds are underutilized and public clouds are expensive.Aiming at these two problems, this paper proposed two scheduling strategies (i.e.,time-first and cost-first)based on performance and cost objectives.Time-first and cost-first allowed tasks to choose the appropriate scheduling resources to meet user demands.In particular,the task with precedence deadline could preferentially select public cloud,and the task demanding low cost could choose private cloud with priority.Both time-first and cost-first satisfied the constraint conditions of the deadline and cost.Experiments demonstrate that time-first and cost-first achieve good performance with respect to the completion time,the cost,the deadline time and the utilization rate of private cloud,compared with other similar scheduling methods.Especially when there are a lot of tasks,time-first and cost-first show better adaptability and superiority relative to standard scheduling methods.关键词
