We have prod and dr servers, we would like to have VIP for them. They are not exposed to internet. Any one server will be active for 1st 6 months, and after DR drill DR will be turned as prod and DR will act as prod for next 6 months. Here, we have upstream systems which pushes files ( csv or text or zip ) via SFTP to our servers which would be nearly 200 - 300mb size per day. Currently, during every DR drill these upstream systems need to raise change request to update the ip before DR drill. So we have decided to have an VIP from our side. So that they can use VIP to transfer files via SFTP. Note: DR server will be up and won't be active.
Note : File transfer is not recommended for SFTP. What are the possibilities to have a VIP.
