云计算中的关键性能挑战之一是托管的虚拟机之间的干扰或资源争用问题。虽然以前的工作已经对特定环境下特定工作负载的干扰进行了经验分析,但需要一种通用的方法来估计在任何干扰条件下的应用程序性能。在本文中,我们提出了一个分析模型来估计作为各种工作负载、系统和干扰条件的函数的性能,包括干扰的强度和长度,对于单VM和多VM系统。在不同场景下与实验结果的比较表明,该模型可以提供准确的延迟估计(误差小于5%)。我们使用我们的模型来分析系统在干扰下的情况,并得出有用的结果来帮助实践者。
One of the key performance challenges in cloud computing is the problem of interference, or resource contention, among colocated VMs. While prior work has empirically analyzed interference for specific workloads under specific settings, there is a need for a generic approach to estimate application performance under any interference condition.In this paper, we present an analytical model to estimate performance as a function of various workload, system, and interference conditions, including the intensity and length ofinterference, for single- and multi-VM systems. Comparisons with empirical results under various scenarios show that our model can provide accurate latency estimations (less than 5% error). We employ our model to analyze systems under interference, and derive useful results to aid practitioners.
