CSR-PDOS-协作：虚拟机与应用集群的结合：面向Internet应用的高响应性全局实用计算平台随着Internet应用的无处不在，面向服务的计算在全局计算中日益占据主导地位。 因此，了解如何为面向服务的计算构建高效的平台对于支持Internet的持续增长至关重要。 本研究的首要目标是获得这样的理解，特别是在构建一个全球性的互联网应用程序的实用计算（UCIA）平台，是高度响应的资源重新分配，提供资源隔离到不同的应用程序，并支持异构执行环境的基本原则进行调查。 这包括在全球UCIA平台上研究不同资源共享架构之间的权衡，并调查有效的算法方法来请求分发和应用程序放置，以说明执行算法的计算成本和这两个策略的交互。 它特别关注全球UCIA、广域应用程序集群和虚拟机中两种基础技术之间的交互。 通过以一种新的方式利用这些技术，这项研究有望在应用程序之间的资源重新分配显着加快。 为了量化其发现，该项目利用了一个广域测试平台，运行一个现成的互联网应用程序样本，并模拟了几个数据中心。互联网应用程序正在将Web从一个信息系统转变为一个全球面向服务的计算平台。 通过提高我们为互联网应用建立高度响应的全球实用计算平台的能力，这项研究将支持在这一重要方向上继续取得进展。

CSR-PDOS-Collaborative: Virtual Machines Meet Application Clusters: AHighly Responsive Global Utility Computing Platform for InternetApplicationsWith the omni-presence of Internet applications, service-oriented computingincreasingly plays a dominant part in global computing. Thus,understanding how to build efficient platforms for service-orientedcomputing is critical in supporting continued Internet proliferation. Theoverriding goal of this research is to gain such understanding, and inparticular to investigate basic principles in building a global UtilityComputing for Internet Applications (UCIA) platform that is highlyresponsive in resource reallocation, provides resource isolation todifferent applications, and supports heterogeneous execution environments.This research encompasses a number of specific directions. This includesstudying tradeoffs between different architectures for resource sharing ina global UCIA platform and investigating efficient algorithmic approachesto request distribution and application placement that account for thecomputational cost of executing the algorithms and the interaction of thesetwo policies. It focuses in particular on the interaction between twofoundational technologies in global UCIA, wide-area application clusteringand virtual machines. By leveraging these technologies in a novel way,this research promises a significant speed-up in resource redistributionamong applications. To quantify its findings, this project utilizes awide-area testbed running a sample of off-the shelf Internet applicationsand emulating several data centers.Internet applications are transforming the Web from an information systeminto a global service-oriented computing platform. By improving ourability to build highly responsive, global utility computing platforms forInternet applications, this research will support continued progress inthis important direction.
