Also, the more you use your cloud vendor's various services in your code, the more subject you are to vendor lock-in.

I won't name any names, but I'm pretty sure this is a big part of the reason why a specific cloud vendor pushed so very hard for us to push a bunch of data into their highly advanced NoSQL big data solution, when the data in question was perfectly happy continuing indefinitely to exist as a few tens of megabytes of CSV files that were growing at a rate of a couple kilobytes per day.
