I'm not entirely convinced the cloud magically makes all these things low maintenance? A lot of the work seems to depend on how simple your architecture is, cloud or no. I also read about plenty of things that go wrong on the cloud: misconfigurations, huge bills, having to do premature optimization work because you pay for every CPU cycle and each GB of RAM.
I'm not saying the cloud doesn't have a place, but I think 99% of the long tail of services don't even need to do migrations at 3am. And running a MySQL instance on a dedicated server with humongous amounts of RAM and speedy NVME drives for $100/month or so is not a bad deal.
But wait until your master worker falls over and you have to promote your read replica. RDS handles everything for me, I just have to monitor it and be ready for any alerts from Promthesus.
I mean I’d say cloud providers measuring everything is a pro. I’ve been at companies in the past that have lost track of all their physical tin. One machine had been doing nothing for 5 years
