How to use Nginx Reverse proxy for Multiple Servers

In this tutorial, we used Nginx reverse proxy for multiple servers sharing a single public IP Address.
We often need an entire dedicated or VPS server for some web application and if you are managing a large number of such servers that obviously need public IP for each to commutate. And consuming lots of public ips is not a good solution for an enterprise in terms of cost. Here the Proxy or gateway concept comes into effect.
As we describe in our earlier video of Nginx reverse proxy that Nginx can be used in many ways like a load balancer, reverse proxy, etc.
Now we are going to use Nginx as a gateway of multiple servers along with reverse proxy. The concept is that I have multiple servers running with a local IP address. And I am going to use one public IP to make all my local servers publicly accessible through Nginx.

#Nginx, #Gateway

Does this mean (@ 10:10), on each of the webservers they should have apache running ? Or would nginx as well be required or do we only need nginx - 1 instance only to connect to each server ?
