We have seen that virtualization provides us with opportunities to reduce computing costs, and this has encouraged the move to the cloud. In this video, I want you to consider one of the often overlooked questions about the cloud, which is, "Who actually owns the data in the cloud?" We saw in the last movie that we are abstracted from the physical side of the cloud provision. That is on purpose. The hardware is expensive and complex, and most customers don't like complex. With the global scale of the cloud, cloud service providers are able to offer services, such as Azure or Office 365, that behave just like a utility company.

A couple of years ago, I was lucky enough to travel from the U.K. to New York on the Queen Mary 2. Another way to think of abstraction is the difference between the passenger and crew on a cruise ship. There were 2,695 passengers on the QM2 and 1253 crew. 18 decks, and four of these are dedicated to the crew. As a passenger, I am abstracted from most of the hidden workings of the ship and the crew. It all goes on behind the scenes. The cloud provider is the same. They are the cruise ship and crew, and you are the passenger.

In a similar concept to the cruise ship, the ice berg is a great representation of data center management. When you subscribe to a cloud service, you can only manage the externally accessible parts that are directly made available to you. Below the surface, the cloud provider manages the hardware, the environment, security, billing, maintenance, and everything else. If you review the contracts of Office 365, Google, and Amazon Web Services, each of them are clear that you own your data and retain all rights.

The cloud service provider is strictly in the role of enabling storage and data access.
