摘要

随着云计算环境的日益普及，对这些系统的高可用性的研究变得越来越重要。软件再生是提高系统可用性的重要机制。本文提出了一个综合的可用性模型来评估动态迁移机制的利用，以使VMM在最小的服务中断下恢复。实时迁移是观察基于时间的触发器执行的。我们评估了五种不同的情况，有不同的时间间隔触发复壮。结果表明，动态迁移可以显著减少系统停机时间。

Availability study on cloud computing environments: Live migration as a rejuvenation mechanism

With the increasing adoption of cloud computing environments, studies about high availability in those systems became more and more significant. Software rejuvenation is an important mechanism to improve system availability. This paper presents a comprehensive availability model to evaluate the utilization of the live migration mechanism to enable VMM rejuvenation with minimum service interruption. Live migrations are performed observing a time-based trigger. We evaluate five different scenarios, with distinct time intervals for triggering the rejuvenation. The results show that the live migration can significantly reduce the system downtime.
