VPS Linux or Windows

For most uses, a Linux VPS is the most common choice: it's usually cheaper because there's no Windows licence to pay for, it uses fewer resources and almost all server tools, including many AI ones, are designed for Linux first. Windows makes sense when you need to run a program that only exists for Windows or when whoever is going to manage it can only get by with windows and a mouse.

The fear beginners have is that Linux is operated by typing commands into a black screen, and on a server that's pretty much the case. But today AI helps a lot with that: you ask it for the command, it explains it and you understand it before running it. Windows, on the other hand, gives you remote desktop and a familiar environment, at the cost of taking up more memory and of updates that sometimes restart the machine at the worst possible moment. It's not about which is better in the abstract, but about what's going to run on that machine.

I have machines with both systems and each has its reason, which isn't always technical. What's on each one, why and what problems each system has given me I explain in "Linux or Windows on my servers". If you have to choose right now, make a list of what you're going to install and check which system each thing runs on: the answer usually comes out on its own.
