IMO a good example here is ops. I grew up in the era where net businesses started by renting colo space or getting a T1 line. When I learned about starting net projects, I learned how to set up all the things needed to get a project going in one of these settings. To me, running ops on a Linux or BSD box is simple; I've literally been doing it since I was a kid. These days it's a lot harder to find people with this expertise. To _me_, buying a DIA circuit and setting up a mini-DC for a business is simple. To most others who experienced Linux through Ubuntu or mostly grew up using MacOS, using cloud-VMs is probably a lot simpler.
