Abstract

We focus on techniques to support admission control and advance resource reservation for applications acquiring information technology (IT) resources from utility grid environments. Utility grid environments offer programmatic access to resources for complex multi-tier applications. In particular we consider business applications which require resources continuously but that have resource demands that change regularly based on factors such as time of day and day of week. We present a statistical demand profile approach for characterizing time varying application resource requirements along with a method that provides statistical assurances regarding the number of resources needed to satisfy the combined requirements of many applications over time. We illustrate the feasibility of our approach with a case study that uses resource utilization information from 48 data center servers. Simulation experiments explore the sensitivity of the assurances to correlations between application resource demands and the precision of the demand profiles.

公用电网环境中应用的统计服务保证

我们重点研究了从公用电网环境中获取信息技术(IT)资源的应用程序支持准入控制和高级资源预留的技术。公用事业网格环境为复杂的多层应用程序提供对资源的程序化访问。我们特别考虑那些持续需要资源的业务应用程序，这些应用程序的资源需求会根据诸如一天中的时间和一周中的哪一天等因素有规律地变化。我们提出了一种统计需求概要方法，用于描述随时间变化的应用程序资源需求，以及一种方法，该方法提供了关于满足许多应用程序的组合需求所需的资源数量的统计保证。我们通过使用来自48个数据中心服务器的资源利用信息的案例研究来说明我们方法的可行性。模拟实验探讨了保证对应用资源需求之间相关性的敏感性和需求曲线的精度。
