Conceptual questions...

Hello.

Still strugging with this...

I just have a quick conceptual question. The more I read, the more it seems to me that this may be true.

Q: is the VIP an actual IP address configured on an actual interface (or alias for an interface) that resides on the load-balancer? So traffic routed to that VIP would then be subject to some balancing algorythm or another (performed by the load balancer), and sent to (via dnat or tunnel etc) a real ip address of a real machine serving a real service?

This may seem like a stupid question, but please bear with me. If this is the case then the VIP is really a real IP, right? I had thought, that the VIP was a floating address between two or more machines, meaning that machine A and machine B can share 10.10.10.10 (for example), and then took turns, so to speak, taking responsibility for that address. I am now thinking that this is not the case.

Can you please tell me if I am right, or correct my erroneous thought processes?

Thanks again!  I will keep at it.

Chris
