Proxmox VE Basic Subscription provides Enterprise Repository access and professional Proxmox technical support for production environments that require stable, tested software updates and direct assistance when issues arise. The Basic tier includes the full Proxmox VE feature set, including virtual machines, containers, clustering, high availability, live migration, backup, storage, and software-defined networking. Unlike the Community Subscription, Basic includes Proxmox enterprise ticket support through the customer portal, with up to 3 support tickets per year and a guaranteed response time of 1 business day during Proxmox business days in Austria. The subscription is licensed per physical CPU socket, not per core, making it suitable for businesses, production virtualization, datacenter infrastructure, and organizations migrating from VMware that require both Enterprise Repository access and direct technical support from Proxmox.
