# LOAD BALANCER

# assume site1.com points to ip1, site2.com to ip2, site3.com to ip3
# fix them each their own pool:
# pool for ip1:443 => node1:443 + node2:443 + node3:443
# pool for ip2:443 => node1:444 + node2:444 + node3:444
# pool for ip3:443 => node1:445 + node2:445 + node3:445

# your loadbalancer takes the public ips, and forwards those to your private ips, on different ports.
