When speaking of cloud computing,

cloud computing is not nearly as green as traditional computing infrastructure setups.

cloud computing firms typically danot share infrastructure resources among multiple customers.

cloud computing costs can vary dramatically, even between customers of similar sizes and scopes from the same cloud computing vendor.

cloud firms require their customers to move their software off$-$site onto the cloud to meet legal requirements demanded by government regulators.

cloud infrastructure is often located in warehouse$-$style buildings specifically designed for computers, not people.
