Proxmox VE is a complete virtualization management solution for servers. It is a powerful open-source platform and supports two virtualization technologies - KVM (Kernel-based Virtual Machine) for virtual machines and LXC for containers. Proxmox VE has a central user interface that allows you to manage not only VMs and containers, but also storage resources, network configuration, and high availability for clusters. It is enterprise-ready and is valued for its scalability and maximum flexibility, enabling you to virtualize very demanding workloads. Proxmox VE makes it possible for you to easily install, manage, and monitor hyper-converged (HCI) data centers.

Proxmox VE Key Features

The Proxmox VE platform has many powerful features, including:

pen-source software, high-available clusters, command line, fencing, a web-based management interface, flexible storage options, REST API, live/online migration, storage replication stack, software defined storage, virtualized networking, backup and restore, two-factor authentication, role-based administration, and VM templates and clones.

Proxmox VE Benefits

Some of the biggest benefits of Proxmox VE are:

• Central management: To manage all tasks of your virtual data center, you can use the central, web-based management interface.
  
  
• Unique multi-master design: Proxmox VE allows you to carry out maintenance tasks cluster wide, from any node.
  
  
• Minimize downtime: With the integrated live/online migration feature, you can move running virtual machines from one Proxmox VE cluster node to another, without any downtime or noticeable effect from the end-user side.
  
  
• Granular access: Using Proxmox VE’s role-based permission management system helps you define granular access to all objects.
  
  
• Multiple authentication sources: Proxmox VE supports multiple authentication sources, including Linux PAM, an integrated Proxmox VE authentication server, LDAP, Microsoft Active Directory, and OpenID Connect.
  
  
• Several storage options: The Proxmox VE storage model is very flexible and the web interface allows you to add multiple storage types (LVM Group, iSCSI target, NFS Share, SMB/CIFS, Ceph RBD, Direct to iSCSI LUN, GlusterFS, CephFS).
  
  
• Collaboration with Ceph: Proxmox VE fully integrates Ceph, giving you the ability to run and manage Ceph storage directly from any of your cluster nodes.
  
  
• Scheduled backups: With Proxmox VE, backups can be scheduled so that they automatically run on specific days and times, for selectable nodes and guest systems.
  
  
• IT infrastructure protection: Proxmox VE has a built-in firewall that works to protect your IT infrastructure. The firewall is completely customizable, allowing complex configurations via the GUI or CLI.

Reviews From Real Users

Here is some feedback from some of our users who are currently using the solution:

A PeerSpot user who is a director at a tech services company says, “The most valuable features of Proxmox VE are the ease of containerization. Overall the solution is generic, feature-rich, and has compatibility.”

Another PeerSpot user who is a head of IT operations at a tech services company mentions that "In addition to the virtualization, the firewall and the routing functions that it provides are valuable."

Deepen D., director and CTO at TechnoInfotech, expresses that "The feature that I have found most valuable is that its storage container, LVM, and everything else work out of the box."
