> Developers want to use PaaS and also AWS or Azure so they can put it on their resume for the future.

I think this is a little disingenuous. Developers want to use them because they already know them. The services composing them are also often well documented by the provider.

I say all of that as someone trying to move a company away from aws, and over to our own hardware.

I want to use them because I'm not paying for it and managing your own hardware is a pain in the ass I'd rather avoid when I could just code instead. Which is not to say that using your own hardware isn't smart, but it is definitely miserable.
