And honestly (not directed at you) that’s a problem endemic with “AWS consultants”. Too many of them are old school netops people who took one certification learned how to click around in the console and now call themselves “AWS Architects”.
They end up duplicating their on prem architecture and processes - costing companies more and not knowing how to automate and increase efficiency.
As far as “powerful GUIs”, one of the earliest game changers for the Mac that helped Apple survive during the dark ages were all of the custom workflows that publishers had created using AppleScript. It wasn’t the better GUI back in the day.
Like if you don't want me using something, don't give it to me. Users gonna use
Seriously though that attitude is antithetical to the spirit of computer nerditry. Who do they think they are telling me what I can and cannot use?
