Abstract: The job and service-oriented paradigm of the Grid enables a wide spectrum of applications to share the massive computational power across the Internet. In this talk, I will present a complementary paradigm of virtual distributed environments to accommodate applications that are hard to map to jobs or service instances, applications that require customized execution and network environments, and applications that require strong containment of risk and security impact. Building on virtual machine and virtual network technologies, we have developed VIOLIN, a middleware system that enables mutually isolated virtual distributed environments in a shared infrastructure like the Grid and PlanetLab. Evaluation results in a number of real-world application scenarios (including education, nanoHUB, and computer worm research) will be presented to demonstrate the practicality and soudness of VIOLIN environment virtualization techniques.
