Amazon offers dedicated servers on EC2
Maybe we should call this one fog computing?
Over the weekend, Amazon Web Services, the cloud computing subsidiary of the online retailer by the same name, announced something called Dedicated Instances for its Virtual Private Cloud services.
In short, it takes what is supposed to be a multitenant cloud and not only locks access to it through a virtual private network, but also ensures that no one else can run their cloudy apps on a physical server that has your cloudy apps running on it.

During that same time, AWS has been very busy adding enterprise friendly features to increase the ability for legacy enterprise applications to adopt EC2.
