Moving to the cloud mean different things to different companies.

For a lot of companies, it's part of a wider "digital transformation" project where they move from 90s custom visual basic applications to a network of 3rd party cloud ones (with a bunch of configuration). While they do it, they re-imagine how the buisness works in a more modern way.

There is a whole IT skillset around that stuff, which is no different now than it was in the 90s but now needs to be accompanied by a bit of cloud knowledge so it gets labeled as a highly skilled cloud role but the actual job is digital transformation.

Similarly, a lot of IT admin is being replaced with devops and architect jobs. Hopefully you end up with way less IT staff but a higher skill level. Devops in a non-tech buisness are building the duck tape and bailing wire that makes the incompatibile single sign on accounts pop into existence when a new user is onboarded, and replace a guy who just sat with a pile of laptops and click the accounts into existence on each one. Way more skill, bit more money, less people.
