Load Balancer configuration is stored in a XML-based file. To
configure it for your system you need to plan before some
network topology issues. As you can see in the following diagram, you
will need two networks:
- A public (maybe firewall-protected) network, recheable from Internet
(your servers’ public IP address). This IP now will be the IP for the
load balancer. Also, the loadbalancer need to be connected to the
private network, so it can connect to the server farm (private
network).
- A private network (non-reachable directly from Internet) where your
servers live. Each server has a private IP address. These servers
build the server farm
This is the basic network topology to manage a LoadBalancer. Also,
you can use other topologies (e.g. A private subnetwork per cluster)
but this is the cheapest (I think). In the following sections I will
explain how to configure each element in detail
