How to deploy a project to a ready-made hosting?

Question

Node.js

I am making a portfolio, first I did it on React, then I decided to migrate it to NextJS.
Well, now I wondered, when I bring everything to mind and finish the project, then what should I do with it next.

As I understand it, not every project that is written in Nodejs cannot be uploaded to conditional hosting, like ukraine. In order to upload a project to hosting, the host itself must support nodejs? And is uploading nextjs different from cra to hosting?

And this is a very noob question. If I have two local servers (One is a project written in NextJS, and the second is api). How should they be deployed on two different domains?

Answer 1

Use a vps server, install some ubuntu on it, install
nginx ,
fasten 2 domains. for example, server.com and api.server.com,
put an ssl certificate (it can be free, for example, letsencrypt)
Through nginx, proxy by address to internal services running on different ports
