I want to try running my node. Tell me can I use low-power free servers from Amazon? Or they are too weak for such purposes.
I would not advise you to use the free VPS from Amazon. Firstly, it is very weak, and secondly, after a couple of months of free use, you will start receiving bills ... it's easier and better to rent the VPS from another provider for more adequate money.
That's true. Contabo is a perfect choice.
