    A slave server can handle remote execution of jobs and transformations.
    It can also be used to run clustered transformations.

    It also allows monitoring and reporting through firewalls where you don't want data to flow.

    [OLTP-DB1]
    |
    [Carte/Slave] -> [Firewall] -> [LoggingDB]
    |
    [OLAP/DW-DB2]

    None of the data being summarized / transformed goes outside the firewall, but the verifications that the ETL occurred do.
