How to get a SSH server for a web domain?

So I have recently purchased a web domain that is called hilltoplax.pro which is not running yet so you can't access it so the reason I want an SSH server is so I can have the website's server to add in HTML and code so the site can have some content. The sites that my friend and I have worked on have an SSH server to add pages to the site, so I am wondering how I can use this for my own website. I would appreciate any help from anyone, so thanks! By the way my site is using Amazon Web Services.
