Collaborative Research: CSR: AES: Virtual Playgrounds: Making Virtual Distributed Computing Real

分布式计算研究的一个重要焦点是解耦资源消费者和资源提供者的角色，动态地从资源提供者那里招募计算和存储资源以满足消费者的需求。这种分离保证了消费者按需访问资源，并促进了供应商之间的供应多样性和规模经济，从而增加了灵活性并降低了成本。这个古老但强大的想法是网格、虚拟化、公用事业和覆盖网络研究的基础。然而，由于供应商和消费者的参与费用高昂，这一目标的实际实现受到阻碍。消费者努力获取、配置和管理远程资源并调整应用程序，而提供商必须调整本地系统配置以实现远程访问。 计算机系统研究的两个不同的线索似乎准备打破这一僵局。面向服务的体系结构提供灵活和可扩展的管理接口和基础设施，而虚拟机技术可以将任何计算机变成安全的用户可配置资源。这些线程的组合实现了基于远程管理和虚拟化资源的动态重新配置的分布式计算的基本新模型。这个项目要解决的挑战（也是机遇）是：将面向服务的网格和虚拟机技术结合起来，以实现对分布式资源的健壮、可伸缩和安全的按需访问，并构造应用程序在动态、虚拟化世界中运行所需的抽象、接口、策略和算法。虚拟化。基于虚拟机（VM）、按需群集和面向服务的体系结构的新兴技术。2.隔离在这些核心虚拟化机制和最先进的安全基础设施的基础上，该项目将研究消费者和提供商之间表达、监控和执行合同安排的机制，包括服务质量和安全保证。动态适应。该项目将研究在虚拟游乐场的新环境下动态资源管理的方法，包括传播关于资源可用性和需求的信息、匹配生产者和消费者以及监测和审计资源状况和流动的机制。 该项目将对建设分布式计算系统以支持研究和教育的社区以及这些系统的用户产生重大的积极影响。该项目将降低成本，提高网络基础设施的投资回报，并消除跨组织共享资源的关键障碍。该项目还将加深学术研究人员与国家实验室之间的联系，为研究生和本科生提供研究培训机会，并增加学生接触先进计算环境的机会。

An important focus of distributed computing research is to decouple the roles of resource consumer and resource provider, and recruit computing and storage resources from providers dynamically to meet demands of consumers. This decoupling promises on-demand resource access for the consumers, and promotes diversity of supply and economies of scale among providers-thus increasing flexibility and reducing cost. This old but powerful idea underlies research on grids, virtualization, utilities, and overlay networks. However, its practical realization has been hindered by high participation costs for providers and consumers. Consumers struggle to acquire, configure, and manage remote resources and to adapt applications, while providers must adapt local system configurations to enable remote access. Two distinct threads of computer systems research seem poised to overcome this stalemate. Service oriented architectures provide flexible and scalable management interfaces and infrastructure, while virtual machine technology can turn any computer into a secure user-configurable resource. The combination of these threads enables a fundamental new model for distributed computing based on remote management and dynamic reconfiguration of virtualized resources. The challenge (and opportunity) to be addressed in this project: to bring together service-oriented grid and virtual machine technologies to enable robust, scalable, and secure on-demand access to distributed resources-and to construct the abstractions, interface, policies, and algorithms that applications need to function in a dynamic, virtualized world.To this end, the Virtual Playgrounds project will address three primary challenges: 1. Virtualization. Building on emerging technologies for virtual machines (VM), on-demand clustering, and service-oriented architectures.2. Isolation. Building on these core virtualization mechanisms and on state-of-the-art security infrastructure, the project will investigate mechanisms to express, monitor, and enforce contractual arrangements among consumers and providers, encompassing service quality and security assurances.3. Dynamic adaptation. The project will investigate approaches to dynamic resource management in the new context of virtual playgrounds, including mechanisms to disseminate information about resource availability and needs, match producers and consumers, and monitor and audit resource status and flow. The project will have a significant positive impact on communities building distributed computing systems in support of research and education, and on the users of those systems. The project will reduce costs and improve return on investments in cyberinfrastructure, and remove key barriers to sharing resources across organizational boundaries. The project will also deepen ties between academic researchers and national labs, provide research-training opportunities for graduate and undergraduate students, and increase student exposure to advanced computing environments.
