We have two servers working on hot availability mode. They are doing ticketing transaction.
Is there a way to provide business contiuity by automatically connecting the users to a remote server. The packets from users should get diverted to the new server using NAT to be implemented with a cisco router.
Replication will be used to keep the remote server uptodate.
How do we implement a time delay for starting the NAT(delay from the time the router senses that the servers are down) and what about restoring back.
Generally speaking, is this idea all right or fraught with problems which I am not able to see.
