Well, this time I tend to agree with your points. Personally, I don’t believe an abstracted black box system can assure you it’s going to work as intended without any issues. To me, that’s more like an illusion, since you know no internals of that black box system. Theoretically you can sue the company if their promises are broken somewhere (e.g. you were offline for longer than expected), but suing Amazon just does not sound real to me. Also, I don’t like isolating the whole system into some ever-changing black box instead of learning how to maintain a real server, but possibly that’s just YAGNI.
