Session
In a landscape increasingly dependent on proprietary virtualization (high costs, limited transparency, low reversibility), this talk explains how Proxmox VE helps organizations regain control with a unified open-source platform (compute, storage, networking, backup), no hardware lock-in, and a strong REST API. It highlights key Proxmox VE 9 improvements (live migration, GPU sharing, SR-IOV, SAN support, easier migrations from proprietary stacks), resilience with Proxmox Backup Server, and closes with roadmap perspectives and practical feedback for a successful transition.
