摘要：

针对目前云平台可靠性定义不明确、无法量化的问题,参考现有标准及典型云服务商的服务等级协议,文章提出一种可量化的测量云平台可靠性的方法,可离线操作,方便用户根据需要选择合适的云服务提供商。通过调取云服务商的MongoDB中的CPU利用率,设定可靠度量阈值,对日志中CPU利用率进行分析得到云服务在特定时间段内的可靠性。实验表明,该方法能测量及区分不同云平台的可靠性能,能够为用户选择云平台以及事后的索赔等问题提供客观的数据支撑。

关键词: 云服务, 弹性, 可靠性测量

Abstract:

Aiming at the problem that the definition of cloud platform reliability is not clear and can not be quantified, a method of quantifying the reliability of cloud platform is proposed based on the existing standard and Service Level Agreement (SLA) of typical cloud service provider. The method can be off-line operation and make users easy to select the appropriate cloud service provider. Specifically, by retrieving the CPU utilization in the MongoDB of the Cloud service provider, setting the reliability metric threshold, the CPU utilization in the log is analyzed to obtain the reliability of the cloud service for a specific period of time. Experiments show that the method can measure and distinguish the reliability of different cloud platforms, and can provide objective data support for users to select the cloud platform and the subsequent claims and other issues.

Key words: cloud service, flexibility, reliability measurement
