Greater control is also relevant to the concerns around data security.

There is no doubt that cloud providers take the issue very seriously, and they will offer service level agreements that provide strong guarantees on the integrity of the data they hold.

But the more sensitive the data the greater the anxieties and some organisations will get more assurance from holding it in their own facilities, where their own people are in charge day to day.

The control can also provide more assurance around the management of risk around legal and regulatory issues.
