Where should I install varnish?

So my web app is hosted on amazon using Opswork.

Currently I have a 1 dedicated instance for Postgresql, 1 instance as my webserver, and another dedicated instance running Redis for caching purposes.

I would like to improve the performance by adding Varnish. Given my architecture where should I install varnish? and also taking into account I may soon outgrow this solucion and be using more webservers behind a loadbalancer.

Any help would be appreciated!

Bye

Varnish will always be quicker if you run it with memory storage - so the one with the most free memory would be a good pick. Even if you don't have enough to spare for the storage, it also uses quite some memory for the connection handling when you reach a bit more traffic.

Further along the road when you want a load balancer a good start would be to use a dedicated server for varnish that also can do load balancing just fine. It's not as effecient as a lightweight dedicated loadbalancer but until you need multiple varnish servers (way down the road) there is generally no point in using anything before it.

You should use Varnish in front of Apache Web Server. However it's fine to reside on Web Server itself and point Load Balancers to Varnish.
