Aquilon is the third generation configuration data-store for Quattor (The first being CDB and the second being SCDB). This talk will cover the architecture and motivation behind Aquilon, experience from a site migrating to it and some examples of the power it can give to SysAdmins. Aquilon features a broker daemon with overall ownership of the system including profile compilation and host notification. The broker models an organisation's infrastructure as objects in a RDBMS, generating configuration code from this as needed. User interaction takes place over a kerberos secured connection to the broker, which delegates sandboxes (cloned git branches) to users when changes to configuration code is needed.
