this is one of the funniest recurring threads on HN. developers finding out what other developers are requiring from their customers. Bonus points for developers finding out that non-cloud solutions still dominate some industries.
Cloud's got nothing to do with it. The thought of standing up a windows box to serve anything other than profiles and user surveillance is simply foreign. Budget webhosting has been a thing for a long time and standing up a *nix VM is also no big deal. In 25 years in industry I never once saw an IIS server used in the wild. shrug
Era may also be a major factor. When I was coming up through the ranks it was common wisdom, even in corporate windows-centric shops, that IIS was a vulnerability factory on par with sendmail.
I read the prerequisites of whatever software im asked to install and do what it says.
I'm not spending the next 3 years of my life trying to make some monitoring platform run on WebLogic i have other jobs to do in 4-8-12 hours.
