Thanks, that makes sense.

One advantage then of running the cloud internally then would be the REST API 
shenanigans would all be within our own network. (This is probably a pretty 
minor item though.)

Seems the best course of action is to spin up some [eg RackSpace] cloud IaaS 
account and start to learn how we would build/deploy the sorts of things we 
build now. Leave looking into setup/admin of the cloud components for another 
day.

The "services" run on clouds are provided by daemons, same as
you are used to everywhere else. They need to be load-balanced
in front and have HA storage in back. It is trendy for the
daemons all to have HTTP-accessible APIs, which have the
advantage of being networked and easily load-balanced, and have
the disadvantage of having to make network roundtrips for
everything.

The "cloud" is a set of machines that are managed by a system
like OpenStack, which arranges for services to come up, go down,
get billed, and so forth. The cloud management system can work
directly on real machines ("bare iron") or manage VMs or
containers. Nothing runs directly "on the cloud", that's just a
metaphor. 

There is no free lunch.
