Good sites to buy / rent minecraft servers?

I want to build a minecraft server with my friends and I know that they cost something. Where can you buy / rent servers securely and cheaply?

Minecraft servers don't always cost something. On aternos.org you can host a server with 2000 mb ram for free, you can take over all settings yourself, etc.

or you host one yourself, which also takes a lot of time and effort

https://mc-host24.de/ for example, Minecraft Game Server from 3 euro per month and Linux Root Server from 3.35 euro per month
