best apache loadbalancing techniques
Hi,
I am planning to deploy the following structure:
--------------internet----------------
\ \ \
proxy1 proxy2 proxy3 ---->\
\ \ \ \
apache1 apache2 apache3 ---> common storage server via NFS
\ \ \ /
mysql1 mysql2 mysql3 /
As You see, there are 3 exactly same copies of one branch that demand
load balancing.
Of course there's one obvious option - DNS loadbalancing when I will
put alll proxies under one host.domainname .
What I want to achieve is simple administration - I want to be able to
make our customers no to use one branch but use others while making
updates etc, while 2 existing branches are online.
What loadbalancing technique should I use to obtain a non-interrupted service ?
We don't want to buy any loadbalancers vrrp protocol etc. . The
infrastructure will be also connected to switch that we dont have
access to.
regards and thank You for your time,
WZ
