Maybe state that it is a Varnish configurator. I initially thought it was a new caching proxy, thinking "Why would anyone need that when they have Varnish?".
Also, adding caches is still resource scaling.

This is a semantically correct. Caching can indeed cut down on resource usage. It isn't always a scale-up operation.
Doing smart things to do more with the same resources, do the same with fewer resources, or by replacing expensive resources with cheaper resources, is optimization, not scaling.
We're being really pedantic right now, though. :)
