Exactly. Cloud was sold as "simple", but in reality you MUST know about data center operations, security in an effective zero-trust environment, failover vs HA vs load balancing, and so many footguns.

The big advantage to "cloud" was that you can provision more resources in seconds. Existing data centers had terrible non-VM and non-good VM management software that provisioning more CPU, RAM, storage was a weeks or months long trial.

And you can still get a 100k bill for hosting a SINGLE text file, cause DDoS and shitty hosting providers who demand unlimited credit is a thing.
