Re: load balancing and fault tolerance without load balancer

NANOG really isn't the forum for this kind of conversation.

That said, look into devices like Alteons, or open source solutions like Balance-NG. Even Apache can be used for this with something like mod_proxy. Good luck.

we plan to set up a web site with two web servers.

  The two servers should be under the same domain
name.  Normally,  web surfing load should be
distributed between the servers. when one server
fails, the other server should take all of load
automatically. When fault sever recovers, load
balancing should be achived automatically.There is no
buget for load balancer.

we plan to use DNS to balance load between the two servers. But, it seems DNS based solution could not direct all load to one server automatically when the other is down.

Is there any way to solve problem above?

we use HP-UX with MC-Service Guard installed.

thanks in advance.
