I know a place where they still do this. They’ve got an 8-digit user count, 7 digit monthly profits, all running on one server that costs something like $20 a month. They’ve downsized a few years ago to single-digit employee number and just sit there and collect profits. And this is why I’m now working for a company that casually dropped a few grand for a glorified CPU usage meter and a few grand on top of that for deployment tool that does the same thing that the old guy at a former place was doing with his trusty FTP client.
