Vertebra
summary
Vertebra is a Ruby agent framework that runs services over XMPP using ejabberd for the server layer and a C-backed client (initially Loudmouth, forked into Loudmouth/Cloudmouth). It implements agent discovery/authorization via Herald, an Erlang discovery DB, and an evented task system (deferable → synapse) so long-running ops don’t block. Memory per agent drops from ~20–30MB to ~10MB with Loudmouth, and Engine Yard and RightScale are already experimenting with deployments.
