I usually cut down on domain/DNS cost by using a free dynamic DNS service called duckdns. It works super well, provides Let’s Encrypt support and sub-sub-domains. (for example your could have https://git.$username.duckdns.org)
I’ve found as a IT noob that Caddy 2 provides as much “batteries inside” and “boiler-plate free” to support me, because I have no Idea what I’m doing. So I just let caddy handle my encryption and reverse proxy to my actual server.
I’m an embedded software dev, who only discovers ethernet protocols on a surface level, because we hadn’t need it yet in previous projects, so I’m a bit lost on how to do cloud stuff. So having all these great tools for free for me to try out and connect from outside to my media servers and stuff is awesome!
It’s not. Like the commenter above said: It’s a fraction of the task at hand. Especially when you design the rest of the system to run only if necessary. Context Switches are what? like 50 CPU Cycles? Store Registers, Store TCB, Load other TCB and load other register states jump back to PC. Maybe some other OS Shenanigans, but that’s basically it.
Now Imagine complex calculations on a 25-Dimensional Matrix.
