The company I work for wants to ensure that a web application is (almost) always available. The application is quite simple, just serving static content in a large table on a single page (auto-refreshing every 60 seconds).
It gets its data from another server (cluster) every few seconds. So, if I had two web servers they would work perfectly well independently. But I dont want users to have to use a different URL when their primary server is down.
Is there a simple way in Linux (I'm using RH 7.0 but willing to change if need be) to allow the two servers to act as one? I imagine that each would have its own IP address and share another IP address. The users would access the shared address.
I really dont want to use a third box (or fourth) box to direct the traffic. Is this possible ?
Thanks in Advance,
