Hetzner
Very cheap, very plain small servers. European data centres.
Use it if
- Price is the deciding factor and you want a server that stays on
- You want your data in Europe
- You are following a guide that just needs any Ubuntu server
Skip it if
- You want a data centre near you and you are not in Europe or the US
- You want hand-holding, managed hosting or support that replies fast
- You need a GPU, which is a different product and budget
Hetzner rents small servers for less than almost anyone, and that is the whole pitch. The control panel is plain, the locations are mostly Germany, Finland and the US, and the reviews from people who run things there are boringly positive, which is what you want from a hosting company.
Where it fits
Everything on this site that needs a VPS works on any Linux server, so the choice comes down to price, location and how much help you want. If price wins and Europe is fine, this is the usual answer.
What you are buying
The same thing as anywhere: a slice of a big machine, an address, a login, Ubuntu (a free version of Linux). The Hermes guide runs on it unchanged.
Honest limitations
I have not run anything here; Vultr is what I used, and this is orientation. Two things people mention: new accounts sometimes get asked for identity verification, which is a nuisance on day one, and the support is email-and-wait rather than live. Neither matters much once the server is up.
Next step
Read what a VPS is if the phrase is new, then pick whichever of Hetzner or Vultr has a data centre nearer you. The guide is the same either way.
