plush: large-scale distributed system management - in progress [link]
plush is a system for deploying and managing large-scale distributed experiments and services on global testbeds, such as planet-lab [link] or the grid. when supplied with an abstract experiment or service description, plush deploys and manages the experiment or service, and it monitors the deployment for failures and reconfigures appropriately. plush also exports interfaces for many types of tools, so as the systems community develops better host monitoring, resource discovery, or resource allocation systems, plush can use those systems, also.

i presented a work-in-progress (wip) report for plush at osdi '04.
