云计算中一个重要的开放问题是性能。很少有云提供商或技术提供量化的性能保证。无论云与企业部署的应用程序相比具有哪些潜在优势，如果部署的应用程序无法可预测地满足行为需求，云基础设施最终可能会失败。在本文中，我们介绍了我们从2009年10月到2010年2月在Windows Azure上进行的综合性能实验的结果。总的来说，我们已经观察到Windows Azure机制的良好性能，尽管在某些情况下（相对于企业内的商品硬件），SQL Azure的平均10分钟VM启动时间和最坏情况下2倍的减速必须在应用程序设计中考虑。除了对Windows Azure进行详细的性能评估之外，我们还根据这些早期观察结果为Windows Azure的潜在用户提供了建议。虽然讨论和分析是针对科学应用程序进行的，但结果广泛适用于Windows Azure中运行的现有和未来应用程序。
A significant open issue in cloud computing is performance. Few, if any, cloud providers or technologies offer quantitative performance guarantees. Regardless of the potential advantages of the cloud in comparison to enterprise-deployed applications, cloud infrastructures may ultimately fail if deployed applications cannot predictably meet behavioral requirements. In this paper, we present the results of comprehensive performance experiments we conducted on Windows Azure from October 2009 to February 2010. In general, we have observed good performance of the Windows Azure mechanisms, although the average 10 minute VM startup time and the worst-case 2x slowdown for SQL Azure in certain situations -relative to commodity hardware within the enterprise- must be accounted for in application design. In addition to a detailed performance evaluation of Windows Azure, we provide recommendations for potential users of Windows Azure based on these early observations. Although the discussion and analysis is tailored to scientific applications, the results are broadly applicable to the range of existing and future applications running in Windows Azure.
