ROI is just reusing old VMWare hardware for 99% of my clients.

In terms of return on investment, Proxmox has provided me with an invaluable learning experience. It's the first hypervisor I've utilized on a server where I manage a cluster of Proxmox instances. This setup has allowed me to gain insights into the intricacies of virtualization and server management while keeping the hassle and stress to a minimum. The learning opportunity has been exceptional, and I've found it to be an enjoyable process.

ROI is hard to calculate. It’s a free solution and, as we do everything in-house, we have to measure the time we need to actually dominate the solution, however, it's really very little time.

Outstanding, worth every single cent spent on it!

I'm definitely getting a return on my investment. I'm buying used servers, and I'm charging like I was charging for new servers, and I'm making a good profit on them. I'm repurposing servers, and I'm making a lot of money from repurposed servers using Proxmox, and they're running.

On a scale from one to five, I would rate my ROI at three.

I've seen a very good ROI.

License & Support-subscription & running maintenance cost is bear minimum compare to other closed source solutions. We were able to use our other existing commodity server part of this cluster.

I'm sure there was or is an ROI, but I don't really get to see that end of the operation.

The time it took for us to see the ROI was very short.

I have absolutely seen an ROI. I am not able to measure the actual value in terms of returns, but because I've invested nothing, apart from the cost of the server or the hypervisor upon which the Proxmox is installed, the value that we've got from it has been huge.

It's hard to quantity but using Proxmox has significantly boosted our server capabilities and service offering increasing our revenue.
