Building a load balancer
To demonstrate the creation and use of load balancers in Neutron, this next section is dedicated to building a functional load balancer based on certain requirements.
A tenant has a simple Neutron network set up with a router attached to both an external provider network and an internal tenant network. The tenant would like to load balance HTTP traffic between two instances running a web server. Each instance has been 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 by using the SimpleHTTPServer Python module on the instances as follows:
ubuntu@web1:~$ echo "This is Web1" > ~/index.html ...Get Learning OpenStack Networking (Neutron) now with the O’Reilly learning platform.
