"As an organisation in retail the pace of change we are facing is so dramatic that our ability to respond as an IT function makes it all but impossible for us to use the traditional model of acquiring IT assets; putting them all together, sticking them in the data centre and making them available for software solutions to sit on," he said. "Having the ability to scale up capacity within infrastructure is of incredible value to us."
In addition, with services from infrastructure providers such as Windows Azure or Amazon Web Services, there is greater flexibility in terms of on-premise hardware requirements.
"Right down the bottom of the stack, we don't need to own anything. Our technology infrastructure need not be ours," he said.
"Increasingly we are looking to move a lot of our IT investment outside the perimeter of our data centres, so that we don't have the hassle of owning and maintaining the tin and wire that runs our business. So we are looking at a number of these organisations and the technology and innovations they provide to do that for us."
