As the full potential of economic and collaborative exchange over the Internet has become clear, Web-based applications and user demand have increased exponentially. Many services now rely on shared infrastructures, called Cloud environments, currently maintained by large service hosting providers. Unfortunately, behind the scenes, Cloud providers are strapped with large administrator costs, costs which consume up to 88% of their budgets, mainly due to server management, power and cooling operational costs. This creates an impediment on the efficiency of this industry, by limiting reinvestment, research and development, and also an environmental problem due to major energy consumption. And demand for flexible, ubiquitous, customizable Cloud access is only going to increase at a steep rate. To address these problems, we propose to design, implement and deploy a novel Cloud resource management framework, Chorus, intended for use as a collaborative environment for interdisciplinary research. Chorus is a lightweight and portable virtualization solution including algorithms, high level languages and tools for performance modeling, anomaly diagnosis and efficient resource allocation. Our techniques will allow for automatic detection and minimization of application interference for resources in Cloud service hosting environments, and automatic power savings, as well as for flexible what-if inquiry for capacity planning and anomaly diagnosis by the system administrator. By these novel proposed techniques, our system, Chorus, will automatically provide performance optimizations towards improving end-to-end Quality of Service compliance for all hosted applications as well as cost reductions for the hosting provider. We will demonstrate the capabilities of our in-lab Cloud environment by running a variety of realistic workloads, ranging from common e-commerce workload mixes modeled after the workloads of the Amazon.com and EBay.com, to functional MRI medical image processing applications.

随着互联网上经济和协作交流的全部潜力变得明显，基于网络的应用程序和用户需求呈指数级增长。许多服务现在依赖于共享基础设施，称为云环境，目前由大型服务托管提供商维护。不幸的是，在幕后，云计算提供商受到大量管理员成本的束缚，这些成本占其预算的88%，主要是由于服务器管理，电力和冷却运营成本。这通过限制再投资、研究和开发对该行业的效率造成了障碍，并且由于大量的能源消耗也造成了环境问题。对灵活、无处不在、可定制的云访问的需求只会以急剧的速度增长。 为了解决这些问题，我们建议设计，实施和部署一个新的云资源管理框架，合唱团，旨在作为跨学科研究的协作环境。Chorus是一个轻量级和可移植的虚拟化解决方案，包括算法，高级语言和工具，用于性能建模，异常诊断和有效的资源分配。我们的技术将允许自动检测和最小化云服务托管环境中资源的应用程序干扰，自动节能，以及系统管理员对容量规划和异常诊断的灵活假设查询。通过这些新的技术，我们的系统，合唱团，将自动提供性能优化，以提高所有托管应用程序的端到端的服务质量合规性，以及降低托管提供商的成本。我们将通过运行各种真实的工作负载来展示我们实验室内云环境的功能，这些工作负载包括根据Amazon.com和EBay.com的工作负载建模的常见电子商务工作负载混合，以及功能性MRI医学图像处理应用程序。
