One thing I don't get about bonding and link aggregation in general - is how to set it up for true high availability / fault tolerance.
Suppose I have a server (cluster) as well as two ISPs:
How do you combine this with a web site? Suppose I want http://www.example.com to always stay up.
I want WAN fault tolerance as well as server.
Which server would you point the DNS for your website to?
Can I somehow give both of those WAN interfaces some 'virtual' ip so if either machine or link goes down, it will still be serving requests?
Do I need some special networking hardware?
I've looked at all kinds of articles, howtos, etc, but none seem to actually explain what is required to do this, and how it works.
