What do you search for to find managed hyperscaler providers.

I was talking to a buddy and i was trying to think of a recommendation and was kinda stumped.

Whats the right term to find managed "cloud" hyperconverged vps providers. That will setup ether a on site/colocation or otherwise custom, physical hardware setup. Basically deliver a working setup and maintain it. But what the hell do i even search for to find a company that does this? "private cloud" just returns a bunch virtual isolated things. Hybrid is kinda close but not really.

Any ideas, or is this something that dosen't exist?

Its no problem finding stuff like proxmox, virtuozzo or nutanix but is no one really offering install / manged services? ( i guess msps would)
