I think the problem is that there is a whole spectrum of services which can
be cloudy and the terms people are using do not clear delineate what is and
isn't covered.

When someone says "private cloud" they could mean any number of things.

- A cloud-like service provided by someone else where the number of tenants
  is limited or the infrastructure is dedicated to a single customer. The
service provider sacrifices some economies of scale to achieve this but can
make it up with premium pricing. 

- A cloud-like service provided internally where the relationship between
  "IT" and other business units is run broadly along the same principles as
public cloud ("elasticity", "on demand", "self service", "automated" etc)
and not the heavily structured relationship most companies currently have
internally.
