I don't know about AWS, but it's also easier for us to sell to clients by saying that Azure takes care of the database updates and backups for us, and can be incredibly robust if they require, and everything is available at the flick of a switch. They are paying a premium for the convenience, but it's a lot of convenience.
That's absolutely true if you're selling to businesses (especially large businesses).
I had the same experience hosting on AWS (having previously hosted on colocated bare metal server). An entire category of sales friction almost entirely disappeared, and it was friction that was common on the largest and most profitable accounts.
