It's fairly easy to setup services without worrying about pages.

I can stand something up on AWS in a couple hours and be fairly confident it will run reliably (assuming their service offering is actually decent--some suck)

We test backups and they never fail. Metrics and logs always work.

I don't think that's the cloud vendors fault. They make it easy to stand up new services so people get overly enthusiastic and create convoluted architectures. Have Postgres but need full text search? OpenSearch is just a few clicks (well hopefully IaC config..) away, let's use that! When you're building yourself and need to setup the stack, instrument, monitor, configure backups the cost is high enough where you say "hey, maybe pg fts is fine for now"
