Rhizoma

Project Description

Rhizoma is a constraint-based runtime system for distributed applications which is self-hosting. The application manages itself to the extent of acquiring and releasing resources (in particular, virtual machines) in response to failures, offered load, or changing policy. Operators developing and deploying application using Rhizoma specify desired application deployment using a form of constrained logic programming, and the Rhizoma runtime uses this to drive resource requests continuously during the lifetime of the application.
