I remember back in the day I had to help a hospital set up some crazy double nat Cisco vpn to another hospital. Old school physical appliance and everything. It was such a pain
It's so funny to me how much the past 10 years absolutely decimated on-prem skills a
In some areas.
I don't know what to tell you folks other than Real Locations doing Physical Things still exist, haven't gone away, and there's actually more of them now than there was.
Given the current state of cyber attacks, all eggs in one basket is probably a very bad thing. For instance, CISA has put out many notices that they consider MSPs a massive security liability. Cloud services are also a weak point.
On prem has become commoditized though. I would bet on aws having stronger security overall than someone running a bunch of physical appliances in their own rack.
Aws doesn't make batch chemicals, they don't transport fuel or nuclear weapons, they don't control water plants or the electrical grid, etc.
Those things cannot expect to have internet access, and should not.
There are tons of billion dollar companies with multiple datacenters or presences in multiple datacenters because of this.
There is more physical hardware right now deployed by companies of all shapes and sizes than there ever has been in history.
CISA PPD-21 Critical Infrastructure Sectors:

* Food and Agriculture Sector
* Government Facilities Sector
* Healthcare and Public Health Sector
* Information Technology Sector
* Nuclear Reactors, Materials, and Waste Sector
* Transportation Systems Sector
* Water and Wastewater Systems Sector
These things need to operate without Internet, full stop. Most of these companies have been around for decades or even centuries. They're not interested in a lot of web/SaaS and can barely even spell SaaS. They're also probably likely to outlive the next few dozen frameworks or language fashions.
