I just don't think this makes any sense: one of the components is 'Cloud Infrastructure (eg Billing VMs)' which is linked only to 'Cloud Service (eq Queue)'. Are we suggesting there are Virtual Machines responsible for billing someone, or does the infrastructure bill for VMs? Then why would a Web Frontend be a good example of the 'Cloud Platform' as a component? I just think it makes no sense. This isn't so much an sample architecture as a random set of buzzwords with no real indication as to how they interact or what they might do.
