VM performance isolation to support QoS in cloud

View publication

Abstract

An increasing number of business workloads are being migrated to the cloud. Recently, cloud providers have been improving the stability and consumability of their systems and offering cost efficiency through utility-like pricing model and dynamic resilience. However, providing performance isolation and quality of services for performance-sensitive enterprise workloads remains a challenge. In this paper, we propose a scheme to achieve performance isolation of collocated VMs through resource bounding, named Fine-grain Virtual Resource Control (FVRC), and introduce a simple yet effective QoS classification built on top of the FVRC framework. Our preliminary experiments with a KVM-based implementation show that CPU and network bandwidth can be accurately controlled and meet consistent QoS requirements while disk bandwidth control still needs improvement. © 2012 IEEE.
