Regarding Server Failover
 

Hi

Am using ubuntu12.04 as webserver. Suppose if my webserver fails in hardware mean other machine have to take over the operations & i should not get any down time. Please guide me to configure.

Thanks in advance

Failover isn't a simple out-of-the-box concept.

First things you have to ask yourself: How important is the info you serve and how much availability (uptime) is wanted. This can come with a very high price tag.

You mention a piece of webserver hardware that fails; What about a power failure, ISP failure, network failure etc etc? All of which can mean unwanted downtime.

I would advise you to search the web for linux failover and get familiar with all possibilities that are available depending on your demands.

...and read up on HAProxy.
