WordPress on SlickStack VPS server in OVHcloud

So maybe I'm just stupid but what is the difference between the VPS servers from OVH homepage and their other website that is called OVHCloud ("public cloud"). Are these two different hosting services or is OVH moving to being a real cloud type of service like AWS and DigitalOcean etc.

I'd like to setup a SlickStack server for WordPress Nginx, which recommends KVM cloud servers. I have read that your NVMe hardware is extremely fast, but worried about ordering the wrong one. So please tell me the difference between your various "VPS" servers?

P.S. I am pretty experienced with web hosting but just FYI your navigation menu is very confusing so I'm guessing other users are confused too.
