I would summarize my experience of different cloud technologies as follows:

Good: EC2, Route53, S3, identity provider (IdP)

Bad: Functions as a service, hosted SQL, weird SQL, elastic anything, containers, logging, reporting, billing, IoT, CI/CD, business apps, event-based services.

I used to consider IdP to be a "bad" cloud technology until I realized it's a trust problem and not a technology problem. I don't want to be responsible for a trust problem. The other parties involved in my contraptions seem to appreciate this perspective.

I’d probably tend to be ok with the standard hosted SQL, since replication is kind of built in to most databases so getting out isn’t much of an issue. However migrating away from a cloud specific IdP is much harder and has some serious lock in.
