First of all, you have to compare in your head what you really want and what you expect from it. How many users will you have, what hardware will you use, etc. For example, if you will process an enormous amount of videos, no VPS server will be enough for you. Many providers do not give root access to VPS, which is also a problem if you need to set something up quickly. You have to wait and rely on strangers all the time. If you have your own big project, buy your own refurbished server with warranty and use server housing like I do.

This will save you a lot of worries in the future, the server performance will be incomparable with a VPS, and as an additional bonus, you can add disks as needed.

Good luck with your choice :)
