Configuring nginx web server with multiple app server of aws stack

I am a DevOps guy and presently I am running my Ruby on Rails application on ubuntu ec2 where the app and also the web server reside inside the same box but we are using mysql RDS cluster. I can see lot of spikes due to more traffic to the web site. So I am planning to change the system. I wanna put web server nginx in a separate instance and web app in a separate instance. But this needs a load balancer which should reside in nginx box, but once the traffic goes up, the nginx instance can be configured to auto scale. What about the app server instance? It can be configured to auto scale but it needs to attach itself to the web server and web server needs to discover the new app server which was created. How can achieve this? Kindly help me out to get this done.

When you are using one single web server at the moment, a transition to using nginx as static webserver and proxy for another backend webserver on another instance really makes sense and will give you performance boost.

However I am not sure if you really need autoscaling. Autoscaling mostly makes sense if you want to react on fast traffic spikes etc. If you have a more or less continuous workload that might increase over time, it should be easier to manually launch and add another backend server in the nginx config. If this does not work for you, you can still have a look at Amazon's Elastic Loadbalancers and Autoscaling afterwards.
