This work addresses what researchers believe are the key impediments to the adoption of cloud computing for scientific as well as commercial advance: portability and application development support for emerging and future cloud systems. The project plan proposes to explore the market viability of combining an open source cloud portability platform (one that executes applications over disparate cloud infrastructures without modification - individually or in concert (cloud hybrids)), with plug-in features that enable new capabilities not available today (cloud hot-swapping of applications, cloud application debugging, disaster/outage recover, large scale data analytics over application data, etc.). The approach enables developers to participate in cloud application life cycle, security, fault tolerance, and cost, simply and efficiently. The runtime support exploits how cloud systems are designed and implemented to automate placement and scheduling, to extract high performance, and to virtualize extant and future cloud services. Such virtualization will enable applications to be written against a single service application programming interface, implemented using multiple cloud fabrics, with high performance and scalability.If successful, this project has the potential for broad impact by facilitating easy and effective cloud application development by a vast and diverse user community. By employing an open source model, this offers the benefits of open source (marketing, collaboration, visibility, self-support, customer confidence building) and makes a software system freely available and therefore widely accessible. This system can thus be used, investigated, and extended in educational and low-income settings free of charge. This approach is also unique in that the goal is to provide a universal platform that levels the playing field across cloud vendors. Developers write programs that execute over the open source application platform, which in turn executes on a wide variety of proprietary public cloud systems - as well as local, private clusters. This application thus precludes lock-in by any single cloud vendor and enables customers to "test drive" public cloud offerings locally in a private setting prior to paying for their use.

这项工作解决了研究人员认为的云计算在科学和商业发展中采用的关键障碍：新兴和未来云系统的可移植性和应用程序开发支持。该项目计划建议探索将开源云可移植性平台（在不同的云基础设施上执行应用程序而无需修改的平台——单独或协同执行（云混合））与插件特性结合在一起的市场可行性，这些插件特性支持当前不可用的新功能（应用程序的云热插拔、云应用程序调试、灾难/中断恢复、应用程序数据的大规模数据分析等）。该方法使开发人员能够简单有效地参与云应用程序的生命周期、安全性、容错性和成本。运行时支持利用了云系统的设计和实现方式，以实现自动放置和调度、提取高性能以及虚拟化现有和未来的云服务。这种虚拟化将使应用程序能够针对单个服务应用程序编程接口编写，使用多个云结构实现，具有高性能和可伸缩性。如果成功的话，这个项目将有潜力产生广泛的影响，因为它将促进庞大而多样化的用户社区进行简单而有效的云应用程序开发。通过采用开源模型，这提供了开源的好处（营销、协作、可见性、自我支持、客户信心的建立），并使软件系统免费可用，因此可以广泛访问。因此，该系统可以在教育和低收入环境中免费使用、调查和推广。这种方法的独特之处在于，它的目标是提供一个通用平台，使云计算供应商之间的竞争环境变得公平。开发人员编写在开源应用程序平台上执行的程序，而开源应用程序平台又在各种专有的公共云系统以及本地私有集群上执行。因此，该应用程序排除了任何单一云供应商的锁定，并使客户能够在付费使用之前在私有环境中本地“试驾”公共云产品。
