Hyper-V vs. Proxmox VE vs. Windows Server

Hyper-V makes a lot of sense in scenarios that will support several Windows Server-based OS virtual machines. The only limitation of those licensed VMs is the hardware that hosts the Hyper-V role. If you need to deploy many servers running Windows Server OS, it is worth the price. Hyper-V also does a great job of managing the server host's computational resources, including memory, CPU, network, and storage.

We used Proxmox to implement private cloud services, for clusters
of a small number of servers, from 3 to 11 with and without high
availability. Allways with ZFS file systems, and we used to install the
root pool in SSDs mirrored and use other pools with RAID 10 in groups of
four, for the virtual machines and containers, for the backups and snapshots, we used magnetic disks with RAID 10, in groups of four. Do
not use an even number of servers because does not facilitates the
implementation of High Availability, because the corosync service must
have an odd number of servers to detect a failed server for the quorum
system. We used a variety of servers, from clone PCs with AMD Ryzen with 6 cores and 12 threads with 64 GB of RAM no ECC, to high end servers with 64 cores and 128 threads per cpu and 2 cpus per server, with AMD EPYC Rome or Milan, 2 terabytes of RAM ECC.

Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.

• Easy to use GUI - very easy for someone with sufficient Windows experience - not necessarily a system administrator.
• Provisioning VMs with different OSes - we mostly rely on different flavors of Windows Server, but having a few *nix distributions was not that difficult.
• Managing virtual networks - we usually have 1 or 2 VLANs for our business purposes, but we are happy with the outcomes.

Incentivized

• BackUp System, provides extensive propiertes and verifications. An exclusive server for BackUp Administration (PBS)
• Hardware Customization. You can select several properties to adapt the hardware to your needs
• Easy administration. You will be able to manage the server with easily accessible tools such as the web console and usage statistics.
• Certificates Administration.

• Backup of workstations & itself - reliably, consistently, with Bare-Metal Restore and deduplication
• File management and Security on a per file/folder/user basis is simple and fully done through an easy GUI
• DNS, DHCP server functions are easy to configure using the built-in GUI

Incentivized

• We manage Hyper-V using both System Center Virtual Machine Manager (SCVMM) and the in-build Hyper-V administration tool, the former being the main product we use as the built-in tool is very light on functionality, unlike VMware ESXi.
• Management of storage is not great and quite a shift away from how VMware does it with ESXi; there is no separate panel/blade/window for LUNs/data stores, which means there is a lot of back and forth when trying to manage storage.
• A dedicated client with all functionality in one place would be awesome.
• Having the equivalent of ESXi's virtual console is something which is absolutely needed.

Incentivized

• The web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

• Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
• Prone to security and audit vulnerabilities.
• The operating system needs more CPU and memory resources compared to other options such as Linux.
• Understanding the licensing model can be abit confusing.
• Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
• Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.

Cheap and easy is the name of the game. It has great support, it doesn't require additional licenses, it works the same if it is a cluster or stand-alone, and all the servers can be centrally managed from a system center virtual machine manager server, even when located at remote sites.

Proxmox VE provides the most capable, yet stable virtualization platform in the market today. Licensing options are also competitive and cost-effective for support, and support is extremely fast and knowledgable of getting issues resolved as quickly and soundly as possible.

I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.

It is quite intuitive. Junior techs are able to provision and administrate Hyper-V virtual server infrastructure with little to no additional training. Documentation from Microsoft is easily avaliable and decently well written. Hyper-V is reliable and does what it is supposed to. Can be admin from an intuitive gui, or aoutmated with extensive powershell.

Incentivized

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.

In the past 2 years our Hyper-V servers have only had a handful of instances where the VM's on them were unreachable and the physical Hyper-V server had to be restarted. One time this was due to a RAM issue with the physical box and was resolved when we stopped using dynamic memory in Hyper-V. The other times were after updates were installed and the physical box was not restarted after the updates were installed.

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

Incentivized

some times server hungs and user sessions were busy to connect

Hyper-V itself works quickly and rarely gave performance issues but this can be more attributed to the physical server specifications that the actual Hyper-V software in my opinion as Hyper-V technically just utilizes config files such as xml, and a data drive file (VHD, VHDX, etc) to perform its' duties.

Incentivized

Proxmox VE's interfacing is always fast to load, both the Web interface and the command-line tool interfaces. Reporting is practically real time almost all the time, and you can see everything in mere seconds, easily able to identify if something is wrong or it everything is in tip-top shape as always desired

Incentivized

need to improve the performance more

I gave it a middle of the road rating - as far as getting direct help from Microsoft this never seems to happen. (Good luck getting ahold of them.) Getting help from online support forums is pretty much where I get all my help from. Hyper-V is used quite widely and anything you could need help with is out there and easily searched for on your favorite search engine.

Incentivized

They are fast, understanding, very intelligent, know their product very well, fast, responsive, and concise. Need I say more?

Incentivized

Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.

We had in person training from a third party and while it was very in depth it was at a beginner's level and by the time we received the training we had advanced past this level so it was monotonous and redundant at that point. It was good training though and would have provided a solid foundation for learning the rest of Hyper-V had I had it from the beginning.

Incentivized

it was my senior who trained Windows Server features and i was satisfied

The training was easy to read and find. There were good examples in the training and it is plentiful if you use third party resources also. It is not perfect as sometimes you may have a specific question and have to spend time learning or in the rare case you get an error you might have to research that error code which could have multiple causes.

Incentivized

it was recorded session and useful

initial configuration of hyper-v is intuitive to anyone familiar with windows and roles for basic items like single server deployments, storage and basic networking. the majority of the problems were with implementing advanced features like high availability and more complex networking. There is a lot of documentation on how to do it but it is not seamless, even to experienced virtualization professionals.

Incentivized

It worked, was easy and super fast to deploy, and provided everything we needed in a matter of minutes

Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.

VMware is the pioneer of virtualization but when you compare it with Hyper-V, VMware lacks the flexibility of hardware customization and configuration options Hyper-V has also GPU virtualization still not adequate for both platforms. VMware has better graphical interface and control options for virtual machines. Another advantage VMware has is it does not need a dedicated os GUI base installation only needs small resources and can easily install on any host.

Proxmox VE is cheaper than VMware, especially upscaling an HA architecture. Compared with other free or less expensive solutions, Proxmox VE is high compatible with more types of hardware solutions and more VM types. From my point of view, Proxmox VE has no competitor at the same price level, it offers the most complete and production-ready HA solution.

Incentivized

They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.

need to reduce a lot

Nothing is perfect but Hyper-V does a great job of showing the necessary data to users to ensure that there is enough resources to perform essential functions. You can also select what fields show on the management console which is helpful for a quick glance. There are notifications that can be set up and if things go unnoticed and a Hyper-V server runs out of a resource it will safely and quickly shut down the VM's it needs to in order to ensure no Hardware failure or unnecessary data loss.

Incentivized

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.

yes i completely agree multi deployment

i like the professional service but need to improve

• Massively positive impact on expenses in my company by reducing our storage needs drastically. We were able to reallocate the budget to upgrading our primary Hyper-V server with pure enterprise SSD's as we reduced the storage needs by over 50% and by this we increased performance by over 400%.
• We have deployed more than 8 servers with EXTREMELY minimal cost using Hyper-V and not requiring another hardware server to host it. We have leveraged our hardware resources in our 2 servers so well that we were able to add many new services, not in place prior, as we did not have the servers to host them. Now with Hyper-V, we deployed many more servers in VM's, purchased OS's & CAL's, but did not need any hardware, which is the greatest expense of all.
• With Hyper-V, our ROI was reduced from 36-40 months on our primary server, down to only 13 months by reducing costs of storage and adding so many more servers, by calculating the "would-be" cost of those servers that was avoided by creating them in Hyper-V.

• Due to the open source nature of Proxmox, we have no licensing costs while training our employees
• We've migrated 100% of our clients to Proxmox and have found improved uptime, and flexibility.
• In the 10 years of using Proxmox, we've yet to lose any data or not be notified of backup issues.

• Ability to keep all files in one place and give access to users makes file management easy to control.
• VPN Access to off-site users is a plus.
• Secure access to on-site SQL data from our accounting and estimating data is a plus.
