Varnish is neither of these.

Interesting question. I have myself been looking at Nginx, mainly for its capabilities as a web loadbalancer / front-end.

From what I've read Nginx is not a cahce per se. It does serve static content (like any other webserver), can be coupled with fastcgi backends to serve dynamic content, and can also be used as an accelerating reverse proxy, in that it handles requests on behalf of slower backend servers (including loadbalancing). It does not (AFAIK) function as a web cache.

Varnish is a web cache, and to serve any content at all you need some sort of webserver behind it.

So its feasible to run Nginx as the server/load balancer and varnish as
the front end cache giving potentially a decent high speed/high capacity
design.

Well, I have no experience with Nginx whatsoever, but yes, both could be components in a high speed/high capacity design.

Yes, those two will complement eachother.

in fact, lovely systems is using that very constellation and
apparently has had good success with it.

they've discribed their setup at the recent german zope conference.
perhaps you might find their presentation interesting:

or perhaps not... i just browsed through the pdf and it's not really
informative without jodok's talk, don't bother with it (i was in the
room at the time and found the story quite compelling).
