Load balancing is a technique(algorithm) used to distribute incoming network traffic onto a group of servers. Load balancers also provide a secondary functionality to the servers they are routing traffic to: they act as a reverse proxy.

The idea for this tutorial is to form a cascading multi load-balancer architecture that can provide a highly available Node.js server running on multiple ports.

This will help us to validate that our infrastructure configuration using the multi-level load-balancer/r-proxy is running the way it should be.
