In the end – for having a stable systembackbone and Servers – a way is to rent a Server in the Cloud – I’ve chosen a dedicated Server at Hetzners for production Server
This gives a perfect setup for running VM in a enviorment that doesn’t require a lot of space/hardware to run the HyperVisor fra Proxmox, even in the free versiion, make its possible to run your own server with VM and Contaniers (both not full Power of Promox VE) – for quickly create and maintenace on Virtual Machine and Containers. And Also are really good functions along with Proxmox Backup Server
