Hi!

We have developed Nova Billing v2. Its documentation is currently available
at http://aababilov.github.com/nova-billing-doc.github.com/. The
documentation includes a glossary and architecture and API descriptions.

Nova Billing v2 is a totally new solution. Its API and architecture were
rewritten from scratch. The new Nova Billing introduces extensible
modularized system with separate components.

Nova Billing v2 can charge arbitrary resources according to custom billing
schemas and, naturally, with different tariffs.

Nova Billing v2 does not depend on any UI for OpenStack Cloud (neither
OpenStack Dashboard nor any other solution). It does not require a
particular OpenStack release. Provided components allow integration with
diablo and essex and this list can be extended.

Nova Billing v2 is event-driven and does not consumes system resources for
periodical polling.

Nova Billing v2 uses a RESTful protocol, so it is easy to integrate it with
miscellaneous user clients and to add third-party components notifying
about arbitrary events.
