I think you are making it more complicated than needed. If you just want reliable service, just figure out who has the most reliable Internet and power and they can host the server. If you want to learn kubernets or docker swarm, you can try that but it will take a ton of upfront work.
Edit: Also get a UPS for the server.
This is an area where AI can be helpful. Tell the AI what Linux distro your on and what you want to do. Most of the time it will give you pretty good answer. If you don’t understand what it is telling you to do, ask it to explain the thing in detail. Most important thing though is to always verify what it tells you before you run stuff. Google search specific commands or use the “man” command to get documentation. The key thing is the AI can make you aware of CLI commands and tools more easily then trying to find what you need on your own.
