摘要
针对现有的IaaS层的资源调度研究在任务调度机制和资源负载均衡机制上存在的不足,以SLA管理、资源调度等理论为基础,结合现有研究成果,对基于SLA的云计算资源调度策略进行一些针对性的研究。提出了基于SLA的云计算资源调度框架,讨论了面向IaaS资源服务提供商SLA管理机制及内容,设计了基于SLA管理的QoS保证机制,与负载均衡模块和任务调度模块交互实现服务SLA的保证,有效实现IaaS资源服务提供商在任务QoS约束下最大化资源利用率的同时获得最大的收益。
According to the deficiencies of both the task scheduling algorithm and resource load balancing algorithm of IaaS layer, SLA-based cloud computing resource scheduling mechanism was discussed based on the theory of SLA management and resource scheduling .A SLA-based resource scheduling framework was proposed .The SLA management mechanism oriented to the IaaS resources service provider and its contents were discussed .QoS assurance mechanism of SLA -based management was designed.The service for SLA was achieved by interaction of load balancing module and task scheduling module .The gain of IaaS service provider was maximized while resource utilization was also maximized under the QoS -constrained condition .
