Dedicated instance for replication server
Choose whether you would like to use a Dedicated instance for replication server.
![Dropdown menu for selecting a dedicated Replication Server instance option.](/images/mgn/latest/ug/images/new-settings-dedicatedrepserver.png)
When an external server is very write-intensive, the replication of data from its disks to a shared Replication Server can interfere with the data replication of other servers. In these cases you should choose the Use dedicated replication server option (and also consider changing Replication server instance type).
Otherwise, choose the Do not use dedicated replication server option.
Note
Using a dedicated replication server may increase the Amazon EC2 cost you incur during replication.
