Open Stack

So I don't want to start to much of a flame-war and am really just 
trying to understand things that may be beyond me (so treat me nicely, ha).

The basic question that I've been wondering revolves around the 
following kind of 'thought experiment' that asks something along the 
lines of:

"""
If I am a user of openstack, say I'm an iphone developer, trying to get 
my 'game' and associated 'game APIs' setup in a manner that is HA (say 
fronted by a load-balancer), using my custom image, secure and visible 
to either an intranet or to the large internet then what is the steps I 
would have to do when interacting with openstack to accomplish this and 
what would the provider of openstack have to give to me as endpoints to 
make this possible.
"""

One of the obvious ones is nova and glance, and the API and usage there 
feels pretty straightforward as is (isn't really relevant to this 
conversation anyway). The one that feels bulky and confusing (at least 
for me) is the things I'd have to do in neutron to create and/or select 
networks, create and/or select subnets, create and/or select ports and 
so-on...

As a supposed iphone developer (dev/ops, yadayada) just trying to get 
his/her game to market why would I really want to know about selecting 
networks, create and/or selecting subnets, create and/or selecting ports 
and so-on...

It may just be how it is, but I'd like to at least ask if others are 
really happy with the interactions/steps (I guess we could/maybe we 
should ask similar questions around various other projects as well?); if 
I'm just an outlier that's ok, at least I asked :-P
