  9. 9. EFFICIENT IT 9 First, it enables organisations to dramatically increase the utilisation of that physical infrastructure. “In many companies, utilisation rates for servers and storage systems hover at around 10 per cent. The virtualisation capa- bilities of a private cloud infrastruc- ture can push these up to 70 per cent plus. So straight away, you’re reducing the costs associated with information management and storage.” Second, with the appropriate informa- tion management tools in place, he says, organisations can move that informa- tion around the infrastructure, accord- ing to that information’s overall value to the business. “In a private cloud, data can be moved and manipulated more freely - that could involve, for example, the migration of data from operational systems to a data warehouse. An organi- sation that can achieve more agility with its information is in a better position to analyst and interpret it. In other words, they can more easily turn data into in- formation.” (For more on information management and storage challenges, see article on page 4, ‘Growing pains’.) Naturally, any talk of cloud comput- ing raises inevitable questions about data security. How do you lock down data when it resides not behind a tra- ditional firewall and subject to stand- ard network security approaches, but somewhere out there in in the cloud? Approaches are emerging that aim to Thomas Bittman, Gartner tackle this issue head-on, but for now, it’s sufficient to say that organisations need to move to a model whereby the security of data and information takes WhAT The AnAlysTs sAy priority over infrastructure-centric approaches.
