摘要
为了实现云计算灵活性,动态伸缩性以及资源共享等特征,云计算系统需预知应用负载趋势,并为其分配所需资源。为实现这一目标,预测技术在云计算资源管理中必不可少。通过分析当前应用于云计算环境中的预测模型,总结了这些预测模型的特点,并在此基础上给出了基于预测技术的动态资源供应的一般流程。针对这些预测模型中存在的不足,从3个方面展望了云计算资源管理中预测模型可能的发展方向。
To deliver flexibility, scalahility and resource sharing, cloud should have foreknowledge of the workload of application and provide the resource it needs. Prediction technique is necessary to achieve this object. Some prediction models are introduced and analyzed firstly. Based on the analysis, the characters of these models are presented and a general process of dynamic re- source allocation is proposed as follows. Because of the inadequacies in these models, there list the future of prediction models from three aspects.
