摘要
针对云计算环境下资源使用呈现的动态、随机、异构等特性,以及资源需求的不断提升给基础资源的管理、调度带来的巨大挑战及问题,提出了基于多策略的私有云资源弹性调度方法。首先在传统协作模型研究的基础上,通过提炼和概括云计算调度的主要组成构件,提出私有云资源调度总体框架;其次,在调度总体框架基础上,以资源的协同管理为核心,给出面向多触发条件的协同调度流程;最后,给出了触发条件中应用集群负载的计算方法。实验结果表明,提出的弹性调度方法能够自动实现虚拟机资源调度,从而优化应用集群CPU、内存、网络等性能。所提方法具有较强的可行性和实用性。
Concerning dynamic, stochastic heterogeneous characteristics of resource utilization and the challenges of management and scheduling of basic resources for continuous improvement of resource requirements, a method based on multistrategy was proposed to schedule private cloud resources flexibly. First of all, a general framework for resource scheduling was proposed by refining and summarizing the main components of cloud computing scheduling based on the traditional collaborative research model. Secondly, with the resource management as the core, the collaborative scheduling process oriented to multi-trigger condition was generated from the general framework. Finally, the calculation method of cluster load was put forward under the trigger condition. The experimental results show that the proposed method can flexibly schedule virtual machine resources automatically to optimize the performance such as CPU, memory, and network in application cluster.The proposed algorithm has strong feasibility and practicability.
