Ruby in the Clouds
summary
Ports Rails and Ruby onto a 10gen cloud platform using a Java-based app server called Babel, a document database with gridFS file storage, and JRuby (1.8/1.9 work-in-progress); sessions and logs live in the distributed DB so any instance can serve requests. Provides an ActiveRecord-like layer xgen base that persists nested objects as JSON blobs; simple Rails apps run with CGI, demos show model CRUD and session sharing working, ActiveRecord support incomplete, millions tested (not billions).
