Another way of looking at at: Where own data-center cost gets to high it might be due to lack of responsibility to act or inability to manage.

A company then have two options: (a) replace/pressure top/middle management to get costs down and processes streamlined or, (b) move to the cloud. Its easier (and possibly good for your resume) to move to the cloud and then a few yours later -- decide again.

So moving to the cloud is sometimes an indicator of an inflexible/stale/mature company.
