Proxmox Datacenter Manager is a centralized open-source management solution for distributed infrastructures. With its unified web interface you can easily monitor and control multiple Proxmox remotes, see health and performance at a glance, and coordinate key operations across clusters and data centers.
I found this software on this link it seems like, Proxmox want to follow VMware to manage all VM / Host in one device
Proxmox also mention that Customers with active Enterprise Support for their Proxmox remotes also gain access to Proxmox Datacenter Manager updates and support.
2025 so many new technology need to be explorer. IT keep growing seems too fast for me to catch it up.
