You are creating a weird one-or-other scenario here.
For example, many people lease baremetal hardware, and use that. And that isn't "cloud". Nor is it on prem. Others still buy hardware, but still rack it at a colo... buying upstream egress and so forth.
Then there are things such as CDNs, so even if you host the primary site on prem, you might use a CDN for larger images or videos, which predates any use of the word "cloud".
My point is, it isn't as binary as one or the other.
The front-ends of the sites therein (e.g. https://www.playshadowvane.com/) are all on Vercel, with the backend/APIs running on exactchange on the on-prem Pi.
