If you work at a company that can't do a cloud infra migration in 36 months, I don't have any good advice for you, but I doubt most commenters on here fall into that bucket. Frankly, I would expect companies that large to be in all the clouds so that you could negotiate them against each other, but I doubt that impacts many people here, and the chance of any of these worst case scenarios happening is vanishingly small.
Some companies even need to check with the laws they reside in if the new cloud vendor can even be used.
Just work in any financial, medical, pharmaceutical, government-related... company and you'll understand that a year is nothing for these companies.
