One of the visible signs of an unrecognized (and therefore, unresolved) dilemma is oscillation between two poles.
I got this from the late Eli Goldratt and the problem-solving tools he created. One of those tools is the "Evaporating Cloud," which is a way to visualize a dilemma of some kind.
I'd suggest that there is an unresolved dilemma here: Should we rent or own data centers?
Over a period of years or decades, you can watch these things flip-flop between two extremes.
It's interesting to me that this dilemma is kind of like a specialization (in OO terminology) of a more generic dilemma, which might be something like: "In general, do we want to own or rent the things we need to run our business?"
If your turn your head a bit, close your eyes a bit and squint, you can see how a dilemma like this can apply to things like "What should be our policy regarding employees vs. contractors? Should we try to hire and retain over a long period of time, or should we rent the people we need to get the job done and release them as soon as we are done with them?"
The overall point is that whenever you see flip-flopping between two poles, think "Unrecognized dilemma."
Sorry if this is vague.
