摘要
提出了一种多因素感知的云服务性能预测策略,它基于综合权衡服务提供商的利益,通过合理定价和性能保障来量化和优化服务满意度,并以之驱动性能预测,并引入效用理论实现服务满意度的合理定价。最后通过模拟实验表明,它能够降低SLA破坏率,有效提高云服务的资源利用率。
This paper proposed a multi-factored awareness cloud service performance prediction strategy. The strategy took the interest of service providers into consideration,and service satisfaction was quantified and optimized in two ways-reasonable pricing and performance guarantee. It used service satisfaction for performance prediction. The strategy adopted the utility theory to decide reasonable price. The experimental results show that it not only can reduce service level agreement violations of service performance,but also improves the resource utilization effectively.
