Jokes aside, I like IaaS as a middle ground. There are IaaS hosters who allow you to spin up VMs as you wish and connect them in a network as you wish. You get direct access to all those Linux boxes and to a layer 2 network, so you can do all the fun networking stuff like BGP, VRRP, IPSec/Wireguard, whatever. And you never have to worry about failing disks, server racks getting full, cable management, all that. 😅
I’m confident that we will always need people who do bare-bones or “low-level” stuff instead of just click some Cloud service. I *guess* that smaller companies don’t use Cloud services very often (because it’s way too expensive for them).
