Pros
"The GUI interface makes the management of KVM easier than ever before.""If you prefer command-line, there are all kinds of command-line options.""I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective.""Good screen and keyboard sharing feature.""Very cost-effective.""It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox.""This solution is open source and easy to configure.""KVM is stable."

"Ease of use, HA, internal 100gbps Virtio network, built-in backup (don't pay $1200 Veeam licence), support for multi-monitors on multiple VMs in KVM, no need to RDP in the VMs to do your stuff (Win, Linux and Mac with SPICE and using 6 screens here (11520*2160).""The setup is very easy.""The most valuable feature is the ease of deployment.""The initial setup is straightforward.""The solution is open source and free to use.""It fits in well with our organization.

Cons
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines.""Lacks high availability across clusters as well as support for Apache CloudStack.""Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view.""Its resource usage can be improved.""There are some issues with the graphics and some software that is very complex.""Business continuity features need to be added.""Monitoring and resolution could be improved.""In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs."

More KVM Cons →

"It could have more security updates such as when a new threat is coming into market.""It's one of those things for me to move things on to the cloud. It's not so easy. I am always on the laptop and have to monitor that because if you want to make strides; you need to stay online.""The only disadvantage of Proxmox VE is that it is a young solution so it does have some bugs.""The only issue I have with Proxmox VE is updating it. You have to manually update it or you have to have a way to update it automatically.""The product is still a little young so it is maturing, but new features are coming out all the time.""There are some things that need to be done using the command-line interface, and these should be moved into the web-based interface.""One issue with Proxmox is that some processes are not automatic. For some processes, you have to do it manually by command line.""The availability of the solution could be a bit better."

Pricing and Cost Advice
  • "It is free for everyone."
  • "The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
  • "We had some problems with the licensing."
  • More KVM Pricing and Cost Advice →

  • "Zero - this is a free solution."
  • "The only thing you pay for is support and it is between $2,500 and $3,000 a year. It depends on the support plan you choose. Support is optional."
  • "I am not aware of the licensing cost, but there is a cost for support."
  • "It's an open-source solution that can be used free of cost."
  • "Because I'm using Proxmox VE for personal use and it's an AGPL license project, I can use it at home for free."
  • "Proxmox is free."

    In a marketing services-related company security is paramount.


    Therefore, you probably will rely on services, especially during maintenance of your network and need support for that.


    When it comes to security and support KVM would be the better option. With in-house engineers, both Proxmox VE and KVM could be chosen. But qualified engineers are hard to come by nowadays, depending on where you live.


    As a side note, I maintain mainly Xenserver, VMware and KVM. When it comes to performance per watt Xenserver would be the king, especially on larger setups. 


    Since your setup is of medium size and if you decided not to go for the aforementioned setups, KVM would be the lesser of the worse.


    Your question depends a lot on the hardware/cloud system you have in mind. More details would make my recommendations more precise.


    Kind regards,

    KVM is a kernel base hypervisor while Proxmox VE is open-source. Technically, Proxmox VE fulfills the smallest business users than KVM.

    And if we go for the quality and support KVM is better. 


    But Proxmox VE has also more features according to business growth.
