Study on Management and Dispatching of Virtual Computing Resources Based on Pool Theory

Cloud computing is a cluster of virtual computing resources pool, converge all computing resources. Cloud platforms manage and schedule unified computing resources. It provides highly scalable and balance the terminals' services. In order to improve the cloud platform for resource utilization and the efficiency of task distribution, this paper proposes a method that the resource manager and scheduler tightly integrated, in which a hierarchical scheduling approach scheduler is used. This paper also discusses the interfaces design of manager and scheduler. Finally, based on prototype system, this paper simulates some test data and some key indicators of the system. From the simulation results, the methods in paper could improve the efficiency of the task distribution and the utilization of resources.
