Hyper-V vs OpenVZ vs Proxmox VE comparison

Hyper-V is a hardware virtualization tool that allows users to create virtual computer environments with multiple operating systems on a single physical server. Each virtual machine has computer parts, such as memory, processor, storage, and networking, and acts like a standard computer - running its own operating system and software programs. Each component of the virtual machine can be configured to meet your specific requirements.

Hyper-V creates a cost-effective, stable, and productive server virtualization environment by running multiple operating systems, such as Windows, Linux, and more, in parallel on one machine or server. Each virtual machine runs in its own isolated space, which means you can run many virtual machines simultaneously but independently of each other. This helps prevent problems such as a crash affecting the other workloads and enables different users to separately access various systems.

Benefits of Hyper-V

• Simplify application testing: With Hyper-V you can easily add and remove operating systems from your virtual machines, enabling you to run and test your applications on each of them all from one single computer.
  
  
• Minimize resource usage and scalability: Virtual machines are easier to manage than physical hardware and less expensive. You can also maximize your server use by allocating its resources more efficiently than you can with physical hardware alone.

Hyper-V key features:.

• Replication and migration: Hyper-V can replicate virtual machines for backups onto different sites. Hyper-V also provides a migration tool for moving a virtual machine from one Hyper-V host to another without causing any downtime.
  
  
• Remote connection: Hyper-V’s remote connectivity tool allows administrators to remotely access a virtual machine.
  
  
• Security: Hyper-V keeps virtual machines secure from malware attacks, unauthorized access, and data breaching attempts.

 Reviews from Real Users

Hyper-V stands out among its competitors for a number of reasons. Several major ones are its flexibility, its replication capabilities, and the fact that its virtual machines utilize a small amount of resources..

Liam L., the owner of a tech services company, writes, “It is actually very low on resources. It doesn't use many resources. It is also very easy to tailor. You can change things like the amount of memory and storage on the fly. It is very stable and reliable. I like its replication feature, which is very good. It is also very easy to move the virtual machines across push servers without any difficulty. Its performance is also very good. Now with this pandemic, a lot of workers are working from home. A lot of workers have been using laptops as their desktop computers, and they would remote into a virtual PC. There is no difficulty, and they can't tell the difference between this and the real one. It is much easier to manage.”

Kevin E. an IT director at Homeland Technology Group, LLC, notes, “We've probably seen a 50 percent speed increase on our SQL server. Hyper-V has also significantly reduced our downtimes with faster boot-up and reboot. If we have to reboot a server, there is maybe two or three minutes of downtime. When we were on a bare-metal server, it could be five to ten minutes due to the total boot time.”

OpenVZ is a container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

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."
