To demonstrate the creation and use of load balancers in Neutron, this next section is dedicated to building a functional load balancer based on the following scenario:
A tenant has a simple Neutron network set up with a router attached to both an external provider network and internal tenant network. The user would like to load balance HTTP traffic between two instances running a web server. Each instance is configured with an index.html page containing a unique server identifier.
To eliminate the installation and configuration of a web server for this example, you can mimic the behavior of one using the
SimpleHTTPServer Python module on the instances, as follows:
ubuntu@web1:~$ echo "This is Web1" > ~/index.html ubuntu@web1:~$ ...
