Hah. I get your point but it would be an easy sell for them. The impossible sell would be to engineers. Executives would just compare operating costs estimates.
Good point, for normal executives (whatever that means). In my little bubble most executives I have to deal with believe themselves to be on par with solution/enterprise architects and they like to show this by saying stuff like: "Let's use microservices and kubernetes for better scalability, everybody's doing it..."
