A big part of the value proposition of cloud is to ensure that you have continuous access to your data, and that you've moved beyond the physical limitations of a single box or a single data center or a single geography. While the move to the cloud can allow greater leverage of compute servers and storage, it also provides the ability to move away from aging, monolithic storage and servers, and gives cloud customers access to their data irrespective of any technical issues that may be going on and irrespective of their physical location. Cloud is supposed to be always on, with resources available on-demand, 24x7. However, how do you deliver all of this with a cloud that's been imprisoned in a box? Clouds cannot be contained in a box.
