Past a certain point, web applications outgrow a single server deployment. In this post we're going to focus on the ways that a single load balancer might distribute HTTP requests to a set of servers.

The way our load balancer is behaving here, sending a request to each server in turn, is called "round robin" load balancing.

The result is very similar to the initial weighted round robin simulation, but there's no need to specify the weight of each server up front.

Let's see this in action in a similarly complex simulation, the same parameters we gave the dynamic weighted round robin algorithm above.
