Limes is an OpenStack-compatible quota/usage tracking service, originally designed for SAP's internal cloud.
Pronounce the name like the Ancient Roman border wall, not like the fruit. (Mnemonic: The original Limes was installed when the Romans wanted to put a quota on Germanic land use.)
Limes can discover capacity and usage for various types of OpenStack resources. It can then be set up to distribute quota automatically among all projects in a dynamic and automated fashion. Both cloud admins and project admins have several knobs to control their quota assignments in a controlled fashion.
- Limes records quota changes in the Open Standards CADF Format, and is compatible with other cloud based audit APIs (e.g. Hermes).
- Quota and usage data can be exposed as Prometheus metrics for monitoring and alerting.
