Ensures a robust, user-friendly virtualization platform with seamless VM management, efficient resource allocation and a strong community for support

Improvements are needed for the API. Currently, there are several features inaccessible through the API, necessitating the use of either the WebUI or the command line interface. While the command line interface suffices, it's apparent that efforts are underway to enhance this aspect. In future releases, one potential feature enhancement could be improved remote screen access, allowing users to connect to the screen of another machine more seamlessly. Additionally, integrating with Terraform or providing better support for Terraform workflows might be beneficial, as there seems to be some lacking in that area. There's a minor inconvenience where you have to switch the license file from the open-source community license to an enterprise license.

Extremely easy to learn and use for beginners

Some features go well with other tools like VMware, where making something on the fly or making some changes on the fly in the area of memory or something is possible. On the fly, you cannot do anything on Scale Computing HC3, though it is a very rarely needed area. Being able to make some changes on the fly is very risky, but even then, you see customers saying since it is an area that is not possible with Scale Computing HC3, it is better to go with some other tools. My company convinces our customers that opting for another solution is not required since a tool that allows us to make some changes on the fly can be very risky, and it is also not something that fits in according to certain policies or good practices.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Many of my customers are moving away from VMware because of its acquisition by another company, which has resulted in skyrocketing prices, making it very expensive and viable only for larger enterprises."

"It works well and shows off the potential of virtual environments."

"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)."

"Proxmox VE, I found to be the easiest to use, quickest in terms of response, and has the best functionality."

"I have a program on my old machine with 380 events, but I need to create new events. This is much easier to do with VFXTHs, and I have the skills to do it. I also have two VPNs running on the old machine, which I can use to get started."

"The initial setup was really straightforward and easy."

"The solution has made it so that I can operate things without having to spend thousands and thousands of dollars."

"With Proxmox VE you get everything in one box, including the ZFS and Ceph storage and LXC container technology, and even the support subscription is really good."

More Proxmox VE pros

"The solution is quite stable; it's rock solid, there are no bugs or glitches, it doesn't crash or freeze, and it's quite reliable."

"The stability is very good; I have no complaints there, as there aren't bugs or glitches and it doesn't crash or freeze."

"Scale Computing HC3 is highly stable."

"I would advise others they should use this solution instead of traditional servers because it's safer, and better for the company."

"The most valuable feature of the solution is the nice GUI."

"The product's initial setup phase is too easy."

"The most valuable feature of Scale Computing HC3 is if one of the devices fails, you won't even notice, the service maintains operation. The customers don't have to waste two, or three days on delays. Additionally, you do not have to waste time with recovery software, it is a lot easier."

"I like that Scale Computing HCR is slimmed down and gives me the features I need and not features that I don't need."

More Scale Computing Platform pros

Cons

"The facility of deployment is an area that needs to improve. The support is an area in need of improvement."

"We had some challenges with management including volume and storage management. Setting it up properly and making it work, specifically shared storage between the virtual machines, is difficult."

"The so-called free support that the solution offers doesn't allow you to access the repositories."

"I would like to see an improvement in the virtualization itself. We use the physical servers for easier migrations, but the virtualization can be better."

"It's one of those things for me to move things on to the cloud. It's not so easy."

"One issue with Proxmox is that some processes are not automatic. For some processes, you have to do it manually by command line."

"It could have more security updates such as when a new threat is coming into market."

"I can't speak to any improvements. It is not lacking features."

More Proxmox VE cons

"The snapshot technology takes up 500 times more space compared to other solutions."

"I would like bigger clusters with more than eight nodes."

"The product could use a better control center."

"Scale HC3 improvements would involve literally fixing up the replication."

"There could be an easier way to see which servers are on each node"

"Scale Computing HC3 said in an announcement they were going to integrate with a backup service which would be good. If they could do this it would be beneficial."

"I've had so many issues with the sales team when I was looking to make some improvements, and improve the performance. They would create so many excuses to force me to buy new nodes all the time and not let me add more memory to each node."

"On the fly, you cannot do anything on Scale Computing HC3, though it is a very rarely needed area."

More Scale Computing Platform cons

Pricing and Cost Advice

"Zero - this is a free solution."

"Proxmox is free software, but if you prefer the support and a more rested repository then you can pay for it."

"There is no subscription required for Proxmox VE."

"Proxmox VE is free of cost."

"The price of the solution is priced low."

"Because I'm using Proxmox VE for personal use and it's an AGPL license project, I can use it at home for free."

"Since Proxmox is open-source, it's freely available."

"The way the licensing of Proxmox is structured, you can use it for free. It is an open-source solution, and you can use it for free, but if you do need support, then you have to pay for the support. So, you can use it in a way that you don't have to pay anything, which is a plus point for me. For people or users who have huge and more intense use cases, the advice or the recommendation is to always pay for support. In case something goes wrong, you can fall back on the team that will attend to your request. For me, at the moment, the cost is zero."

More Proxmox VE pricing and cost advice

"I pay for Scale Computing HC3 and it includes customer service for one year. We paid for an additional year for customer service but that includes the updates and everything for the software. Additionally, the licensing is for Windows, which is the same for everybody."

"I give the pricing a nine out of ten."

"The product is worth the money, but I would not say it's very cheap or very expensive."

"rate HC3's pricing a five out of ten since it is affordable."
