Open Stack

That's true. Heat's job is mainly to call other OpenStack APIs in correct
order in order to achieve desired combination of infrastructure resources.
Physically though it may run on a completely different host where these
files are not present, even including a host that is outside of the
datacenter where OpenStack is deployed (so called Heat standalone mode).
The only info Heat knows about other OpenStack services is what Heat can
get trough their API.
