We are a medium sized department in big state university and wish to implement a failover system for our web applications, I am looking at some software applications like xosoft that synchronize the master and failover databases in real time, I am having the following problem in setting up this system:
Since we are a part of the university, our servers are accessible to the internet only thru the university network, though we maintain our own internal network, if some one has to reach our servers from outside it has to come thru the university network, there are two scenario's where our system can be unreachable.
1 when our network or server or database is down
2. when university network is down.
when our network is down i guess we could simply redirect the university dns server to point to the failover server located at a far off location
but what is the solution in case the university network is down, how do i redirect requests to the fialover system.
thank you in advance
