Definitely IaaS. When you start talking about MAC addresses, VLAN IDs, etc.
you're venturing well into the underlying hardware fabric which is
ultimately someone else's problem - I don't see any of these things
appearing in current IaaS APIs[1].

Basically think of infrastructure services as everything up to the operating
system interface (be that an API, CLI or a GUI).

Platform services (PaaS) on the other hand include [most of] the solution
stack... any app servers, databases, script/bytecode interpreters, etc. -
think LAMP. You can just take your app and use it (in many was like it were
a virtual machine - which is why the next step for us will be a small one).

Software services (SaaS) then add the application itself.

OCCI is most definitely IaaS.

1. That is not to say they're not important - they are, particularly for "I
can't believe it's not cloud" moreso than public cloud, but if they appear
in OCCI they'll be optional.
