Re: Webserver Redundacy
For web server redundancy I strongly recommend a pound server in front
of the real web servers.
Pound "knows" how to distribute load among back end web servers and
knows how to check if the servers are available.
The next step is a dedicated appliance but is more expensive and does
practically the same thing.
DNS round-robin is not very accurate and best to be avoided. However the
DNS could be used for a geographical distribution of web servers (akamay
style) with multiple views depending on the query source IP.
