Despite the rapid growth of distributed shared infrastructures such as PlanetLab and the Grid, a gap exists between the current practice and their full potential. Especially, many users wish to obtain their "own space" with full privilege in a shared infrastructure to run arbitrary distributed applications. This research introduces the concept of "virtual distributed environments" (VDEs) as a new sharing paradigm for distributed infrastructures. Based on virtualization technologies, VDEs are autonomic, mutually isolated entities, providing individual users with privileged, customized, and confined distributed environments. To realize this vision, the following new research challenges are being addressed: (1) distributed environment virtualization and logistics, (2) shepherded self-adaptation of virtual distributed environments, and (3) trusted monitoring and logging of virtual distributed environments. Solutions to these challenges are evaluated in a number of real-world application scenarios, including computer system emulation for education, e-Science service for the nanotechnology research community, and virtual playgrounds for Internet worm observation, investigation, and defense. In particular, the research and education activities of this work are closely related. Leveraging the research results, an education platform is being developed for distributed and network systems emulation. It provides students with hands-on system experience that would otherwise require expensive, dedicated equipment. This research will open the door to new opportunities for application/service deployment and distributed system experimentation. The realization of VDE will encourage public use of the emerging cyberinfrastructure by accommodating a wide range of science and engineering activities including education and research portals, virtual collaboratories, and cyber-defense testing grounds.

尽管分布式共享的基础设施（例如PlanetLab和电网）迅速增长，但目前的实践与其全部潜力之间存在差距。尤其是，许多用户希望在共享基础架构中获得具有完全特权的“自己的空间”，以运行任意分布式应用程序。这项研究介绍了“虚拟分布式环境”（VDE）的概念，作为分布式基础架构的新共享范式。基于虚拟化技术，VDE是自主，相互隔离的实体，为个人用户提供特权，自定义和密闭的分布式环境。为了实现这一愿景，正在解决以下新的研究挑战：（1）分布式环境虚拟化和物流，（2）对虚拟分布式环境的牧羊人自适应，以及（3）对虚拟分布式环境的可信度监控和登录。这些挑战的解决方案在许多现实世界应用方案中进行了评估，包括用于教育的计算机系统模拟，纳米技术研究社区的电子科学服务以及用于互联网蠕虫观察，调查和防御的虚拟游乐场。特别是，这项工作的研究和教育活动密切相关。利用研究结果，正在为分布式和网络系统仿真开发一个教育平台。它为学生提供了动手的系统体验，否则这些体验将需要昂贵的专用设备。这项研究将为应用/服务部署和分布式系统实验的新机会打开大门。 VDE的实现将通过适应包括教育和研究门户，虚拟合作者以及网络防御测试场的广泛的科学和工程活动来鼓励新兴网络基础设施的公众使用。
