> biggest corps still have only 20k employees or so
While I agree with your general statement, Corps can easily have 100-500k people and keep being a fairly unknown brand.
Employees is not equal to users. I worked for a not so big insurance company that had 1500 employees, but the number of users (not clients! People using apps whole day) of our systems were around 50k.
Some challenges in systems I have to integrate with now, are that with 10k users they saturate any network interface Corp throws at it, even though it has hundreds of separate instances (that don't have to sync each other). And we are still talking about a web app on prem, on decent hardware. Not exactly a standard one, but still.
