> Hey, I really appreciate your feedback
Indeed that's great, thanks.

Yeah, for _sure_ we'll support multiple services per machine. If
desired, a full deployment will use a single machine, actually.
That's one of the benefits of using Ensemble vs. images: you'll be
able to define how to distribute the services if that's wanted.

In addition to what Ahmed said, just to be clear, just to be clear,
the formula author is actually free to design those details as makes
most sense for the use case at hand. Of course, the ideal approach
will end up being most used, and will be part of the core set of
formulas we'll provide by default.

Right. In any case, whatever you need just drop us a note. We'll be
happy to explain how it works, or even tweak/improve the way it works
if that's necessary.
