Previous job, I ran website on RDS for about 7 years and only touched the control panel to restore from a backup when we'd screwed up the data, and to tell it when to upgrade. That was worth quite a lot in ops time and piece of mind.
Database crashing on a hosted service is such a rate event unless you mess it up yourself running rouge queries. No surprise there. It doesn't have to be AWS though. Can be Digital Ocean or anything else.
