The backbone of IT infrastructure is evolving towards a service-oriented model, in which distributed resources (software services, virtualized hardware infrastructure, data repositories, sensors, and network overlays) can be composed as a customized IT service on demand. In particular, cloud computing infrastructure services manage a shared ``cloud'' of servers as a unified hosting substrate for diverse scientific applications, using various technologies to provision servers and orchestrate their operation. At the same time, high-speed networks increasingly offer dynamic provisioning services at multiple layers. Network-connected clouds offer a general, flexible, and powerful model to scale up computing power for data-intensive science applications running at multiple cloud sites. The software produced in this project offers interfaces and control policies for application-driven orchestration of federated clouds interconnected by advanced networks.The project develops software to link cloud computing clusters to other cyberinfrastructure resources through dynamically provisioned networks. A principal focus is to extend popular cloud infrastructure software with hooks to connect provisioned machine instances running in the cloud to external resources through dynamic circuit networks. The project enables cloud applications to dynamically request compute resources at multiple points in the network, together with bandwidth-provisioned network pipes to interconnect them and link them with other services and data repositories. The orchestration framework is based on the Open Resource Control Architecture (ORCA), an extensible platform for dynamic leasing of resources in a shared networked infrastructure. The resource allocation policies are enabled through semantic resource descriptions and extended intelligent SPARQL queries. Driving applications for this project are MotifNetwork, IMG/JGI and Supernova Factory and sensor networks linked to cloud resources (CASA). Development and demonstrations leverage the Breakable Experimental Network (BEN, a multi-layer optical network testbed located in North Carolina), NLR and ESNet.

IT基础设施的骨干正在向面向服务的模型发展，在这种模型中，分布式资源（软件服务、虚拟化硬件基础设施、数据存储库、传感器和网络覆盖层）可以按需组合为定制的IT服务。特别是，云计算基础设施服务管理服务器的共享“云”，作为各种科学应用程序的统一托管基板，使用各种技术来提供服务器并协调其操作。同时，高速网络越来越多地提供多层次的动态供应服务。网络连接的云为运行在多个云站点上的数据密集型科学应用程序提供了一个通用的、灵活的和强大的模型来扩展计算能力。该项目中生成的软件为应用程序驱动的由高级网络连接的联邦云编排提供了接口和控制策略。该项目开发软件，通过动态配置的网络将云计算集群与其他网络基础设施资源连接起来。主要的焦点是扩展流行的云基础设施软件，通过钩子将运行在云中已配置的机器实例通过动态电路网络连接到外部资源。该项目使云应用程序能够在网络中的多个点动态请求计算资源，并使用带宽预置的网络管道将它们相互连接，并将它们与其他服务和数据存储库链接起来。编排框架基于开放资源控制体系结构（ORCA），这是一个可扩展的平台，用于在共享的网络基础设施中动态租赁资源。资源分配策略是通过语义资源描述和扩展的智能SPARQL查询启用的。该项目的驱动应用程序是MotifNetwork， IMG/JGI和超新星工厂以及与云资源（CASA）相连的传感器网络。开发和演示利用了Breakable实验网络（BEN，位于北卡罗来纳州的多层光网络测试平台）、NLR和ESNet。
