>Realise that isn't at scale for some

This is one thing that REALLY frustrates me about enterprise. So often the c-suite wants to push for going cloud platforms (aws, azure, snowflake, along with all the costs, "because they need it". It's this narrative of scale that drives these discussions - so few companies are genuinely dealing with 200,000 requests per day!

There are lots of valid business cases for cloud. Scale is way down the list on most.

To be fair for this sites audience if there are true startup ambitions it "might" push it higher up than more normal use cases.

Genuine question - have you come across good/useful case studies/summaries of going cloud?

All I can really get is "pretty toys", "everyone is going cloud", "we don't need to have network engineers (we now need azure network engineers)", etc.

I haven't I'm afraid.

I have been involved in several cloud migrations of existing systems. These where all successful and a lot was driven by not having to own and manage the underlying servers and/or the need to replace aged systems at the very last point possible.

Like most things understanding the rationale and desired outcome are key. One of the things you get from going to cloud is, as you point out, is a wider group of people who already know and understand key parts of the architecture/infrastructure choices.
