Subject Re: Load Balancing through Apache
Date Tue, 30 Jul 2002 15:49:30 GMT
Not only will you need some sort ip-failover solution but you will have
to figure out how to store your data so that it is accessible to both
machines. Be it centralized storage or some sort of mirroring. Once
again, there are many options to choose from both commercial and
free-software based. Once you have determined what kind of setup you are
aiming for and what your requirements are, look into what
software/hardware products suit your needs.
