RE: [cobalt-users] Load Balancing Cobalts ?

["Mathew Clark" <matt@xxxxxxxxxxxxxxxxxx>]

Which ever solution you end up using, try to eliminate SPFs (single points
of failure).

Regarding the NFS solution - aside from the fact that if the NFS server goes
down, it takes your websites down with it, as long as the server is not on
global IP and is sitting far behind the firewall then your security risks
are probably restricted to internal tampering - provided the firewall is
configured correctly etc etc

The DNS round robin solutions sounds great until one of your DNS servers
goes down.  If you had three servers and one goes down, then best case is
that 33% of your traffic will be rejected.

We have found piranha most effective along with rsync to mirror updates.  I
would not recommend using rsync to mirror any Database content - you are not
guaranteed a working replication.

Be prepared for the fact that any load balancing system with no single
points of failure is going to cost...just in terms of raw hardware
requirements.
