Swapping an enterprise’s cloud provider is at least a 6 month endeavor and that would be with all hands on deck, I estimate two years at least and that’s still with significant tail wind. While things are crazy, best bet is to hold tight and sign the checks and prepare.
My experience is that it can be anything from relatively easy to frocking impossible. Very hard to put a timeline on.
But if we are talking about tariffs (and not a ban) then a partial move is also relevant. And, at least in my anecdotal experience, a non-trivial fraction of our cloud-cost is pretty simple services which can be moved. It's almost like a 95/5 kind of thing, moving 95% of the stuff would take 5% of the time.
Having a hybrid cloud setup is clearly more hassel, but it's doable.
