The opinions of Gnome are not a match for mine.

KDE let’s me get really specific on the things I want to, and its well supported.

Just that simple for me!

Proxmox is a server OS based on Debian which is oriented on running virtual machines and Linux containers.

The physical server runs proxmox. The services can all be individual containers (LXC’s).

Adding to the number of servers (and migrating containers later) is a benefit of Proxmox, since you can buy another PC to be a server later, and easily expand as you go.

Proxmox.

Each service becomes an LXC. Docker containers can be migrated to LXC, or be contained within an LXC dedicated to docker.

Running out of processing power? Add another server, add to a cluster, and migrate services (LXC or VM) over.

Having run Fedora, Debian, Ubuntu, CentOS, RHEL, slack, even Oracle Linux - Proxmox is what I run for myself (and some clients).
