Proxmox VE is a very fast and powerful solution. It offers feature-rich virtualization, has open-standards compliance, and also includes redundancy and failover capabilities. What I like about Proxmox VE is that it lets you rack and stack two or more nodes and enables you to be up and running with a one-node failure tolerance in very little time. Proxmox VE’s integration with ZFS is also fantastic. It allows you to create pools to store your VM images and data on very easily and their great web UI makes it easy to check drive health, ZFS scrub status, and other things. I think the best part of the web UI is that everything is configurable from the web user interface without having to use the command line. It also has graphs and additional visualizations so you can evaluate the performance of everything. Beyond that, even though you can use Proxmox VE on a single server, the solution makes it easy to set up a high availability cluster on multiple hosts if needed.
Regarding Oracle VM VirtualBox, I would say its most valuable features are its virtualization, its compatibility with older OSes, and its testing of environments without causing interruptions or any harm to production. Besides making it possible to run multiple VMs on a laptop or desktop, its ease of deployment makes the solution appealing. Not only is it easy to set up, but the software is free. Moreover, it has a nice interface. However, I think Oracle VM VirtualBox could use some improvements on its reporting as well as on its network settings for VMs, which can sometimes be hard for the average user to find and understand.
Conclusion: While Oracle is a safe and excellent option when it comes to virtualizing an operating system, I would suggest Proxmox VE because it is newer, has a lot of powerful features, and is a very reliable and stable solution.

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.

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.
One of the best things about Proxmox VE is that it is open-source and very inexpensive. You get all of the same features as with the more well-known products. Proxmox VE is very easy to deploy - it can run on anything. It is extremely scalable, stable, and very user-friendly. Proxmox VE allows users to easily create virtual machines. It is based on Debian Linux, using KVM.
Proxmox is a young solution and there are still some bugs to work out. When you need technical support, there is a cost, and this can add up quickly. There are some things in Proxmox VE that need a command-line interface. We think it would be better if it were more a web-based interface.
The initial setup with the Hyper V is very simple. It is a Microsoft product so it works seamlessly with all Microsoft products, and does very well with other solutions as well. The Hyper V is a great end-to-end solution that has an amazing fail-over feature, which helps minimize downtime and maintain productivity.
Hyper V can have some stability issues; your stack can become bloated easily. The scalability of this solution really depends on the licensing you purchase. If you are looking to scale up or down you will need to purchase the data center license, which can get expensive.
If you are looking for a Hypervisor strictly from a cost of ownership point of view, Proxmox VE is the solution to choose. It has many of the same features as other products at a very competitive price.
We chose Hyper V, as we are deeply committed to the Microsoft ecosystem and we were also looking for some management solutions that Proxmox does not offer. We also found the fail-over feature very important to many of our clients’ needs.
