基于分布式离散事件系统监控理论的云资源动态调度
Dynamic Scheduling of Cloud Resource Based on Control Theory of Distributed Discrete Event Systems
摘要
Abstract
Given the complex dynamic and distributed nature of the cloud environment together with the discrete characteristic of cloud data center entities, we propose a dynamic scheduling strategy of cloud resources based on the distributed discrete event systems ( DES) theory. First, we construct the cloud environment as a dis-tributed DES composed of numerous subsystems, which include the physical server subsystem, the virtual ma-chine subsystem, and the cloud task subsystem. Then, we apply supervisory control theory of distributed DESs to deal with the dynamic scheduling of the cloud resources. Through the control from local controllers and the information exchange between the global and local controllers, the proposed strategy achieves the overall optimization of the cloud resources and guarantees the rational allocation of the subsystems′resources. Moreover, the scheduling of the resources′ load balancing improves the overall utilization of the cloud re-sources and the quality of the cloud service and enhances the performance of the entire cloud platform. Exper-iments indicate that with the increase in tasks, the proposed control strategy has obvious advantages in the uti-lization rate and the execution time compared with the traditional strategies.关键词
