Description RHOS Integration 2013-12-12 13:49:44 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/ledger-quota-subsystem.

Description:

This blueprint describes a concept of a subsystem (codenamed Ledger) which could provide core OpenStack components with a unified interface to quota management and resource accounting logic. Having such a subsystem would make quota handling code almost independent from any existing OpenStack component source tree and thus 
- would ease the development of the quota-related functionality.
- would simplify the introduction of quota-handling capabilities into those OpenStack services which do not support them yet, e.g. Glance.

The following aspects need to be covered
- General architecture and data model
- API and points of integration with OpenStack services
- Configuration of the subsystem
- Quota code base extraction and isolation issues
- Migration from the existing quota mechanisms
- Packaging and distribution
