Server Manager
InitialSync
Extractor
Applier

You can run the Extractor and Server Manager on any machine that can access the source database logs. In this case, you would not install Data Replication on the source system. Also, you can run the Applier on any machine that can access the target database by using the target database connectivity client or ODBC driver.
