Proxmox Virtual Environment (VE) is an open-source platform used to run and manage virtual infrastructure on physical servers. It lets you operate full virtual machines (VMs) and Linux containers (LXC) from one web interface.
Teams use Proxmox to consolidate hardware, keep workloads isolated, and use resources more efficiently. It includes built-in clustering, backups, firewall controls, and storage integrations such as Ceph, so it can scale from a single home server to multi-node enterprise environments.
In practice, people use it for self-hosting, lab testing, internal business apps, and production virtualization when they want flexibility without high license costs.
