面向成本优化的云计算资源分配方法研究

Cloud Resource Allocation Method Based on Elastic Resource Adjustment

针对云计算运营环境中,云服务提供商租用云资源提供商的资源,向用户提供服务的场景,以优化云服务提供商的成本支出,增加其运营收益为目标,设计了一种面向成本优化的虚拟机资源分配方法。该方法全面考虑了现货、预约和按需3种资源分配模式,引入风险控制因子规避现货市场的资源风险,制定出成本优化的资源分配方案。所提方法在满足用户满意度基础上,有效实现了虚拟机资源成本的优化,增加了云服务提供商的收益。

For cloud computing operating environment, cloud service providers leased cloud resources provider of resources, to provide the service to the user of the scene, taking the optimization of a cloud service provider costs, increase the operation profit as the goal, the design of the virtual machine resource allocation method for cost optimization was proposed. The method comprehensively considered the spot, appointment and on-demand resource allocation model, control factor was introduced to avoid the resource risk, the resource allocation scheme for the optimization of the cost was formulated. The proposed method meets the users＇ satisfaction, effectively realizes the optimization of virtual machine resource cost, increases the cloud service provider revenue.
