Proxmox Virtual Environment for hosting providers?

[poetry]

Hello,
Just interested how much build in multi user support there is in proxmox-ve? Is it usable for multi user (each user is different customer/company that has access to their resources? - they can build or destroy their vms, have defined ip addressed/networks that they can use, hdds...). How would you expose the web management just directly via internet (sounds like a bad idea) or you need to build your own interface that communicates with proxmox-ve via api?
I see there are some hosting providers partners with proxmox how they actually do it? What is a good practice?

The best route is using the API. If you are using something like WHMCS there are modules to do all of this automatically. For example modulesgarden has a few to do exactly what you describe.
