Rivaling the stiffest and competition in its category this solution suffers only from being young

Pros and Cons

  • "That the product is free and still has all the features you expect is a huge benefit."
  • "The setup is very easy."
  • "The product is still a little young so it is maturing, but new features are coming out all the time."

What is our primary use case?

We use this solution as our virtualization platform. It is a hypervisor that we use for our virtual needs to run servers.  

What is most valuable?

One of the things that I found most valuable is how easy Proxmox is to deploy. It can run on anything. Right now we are running it on some file servers that we have without any special configuration.  

I also like how it has got the same high-availability features as you get in a product like VMware. I get those benefits and I do not have to pay the $17,000 a year for the VMware license to enjoy them.  

Because Proxmox VE is open-source, the only expense we have is the support costs. You get an easy to use GUI that you can use to look to see who your virtual clients are and what hosts they are living on. You can also essentially vMotion — which is a VMware term but the feature in Proxmox does the same thing — to transfer a system.  

It is host-aware, so if the host Proxmox is living on crashes and there is another host in the cluster, it will automatically failover. That is just a great capability. It also can do the same thing if performance on the given host exceeds a certain threshold. You have the option to configure that as you want it with the product. It will automatically move to a different host to improve performance with the system and, in turn, improve the performance of the application running on it.  

What needs improvement?

Really every user interface could use a little bit of improvement. It is already very user-friendly at the present time but there are some ways that it can get even better.  

Another area that might have room for improvement is either building in or having third-party tools that could report on CPU and memory usage across your virtual platform. They have those tools for VMware and that helps you to point out resource bottlenecks so that you can right-size a VM. If a VM is soaking up too many resources, it is defeating the purpose of virtualization. Proximo is really missing those kinds of tools right now. You have to do that on your own. So that could definitely be an opportunity for improvement. It is not necessarily just room for Proxmox to grow, it is more of a possibility industry-wide for these products.  

For how long have I used the solution?

I have been using Poxmox VE (Virtual Environment) for the last 12 months.  

What do I think about the stability of the solution?

The stability of Proxmox is good. It runs well, and they are constantly looking to improve the product. By "they" I mean the core group at Proxmox themselves. But the key part of the updates is everything is well-tested and the goal is obviously to maintain stability while upgrading the functionality.  

What do I think about the scalability of the solution?

Proxmox is scalable. Let's say you wanted to add an additional host, or you wanted to add additional hosts just from memory or virtual CPUs, just for additional resources. You could just add a host. You do not need to buy a license to do it. That is better than just scalability, it is scalability without cost.  

With VMware, you have to buy a license or you need to use it free for 30 days, but eventually, you are going to have to procure another license. With this product, I can just take whatever server I have, install Proxmox on it, and that is it. I introduce it to the cluster during the install, and everything is up and running.  

So it is very, very easy to scale at will. I have not seen any limitations of the product itself that would prevent me from adding additional systems or or other resource into a cluster. By resources, I mean CPU, memory, drive space, or other performance enhancement.  

We do not even have to have anybody on staff who is here to maintain the system. It is just another part of the existing architecture that gets monitored by the systems that we already have in place. We have monitoring set up so that we can tell how the system is performing overall. We can generate reports within Proxmox to tell us how it is performing in a given cluster and how many hosts it has.  

We plan on keeping it as our virtual platform and we are pretty confident that it can scale with our needs. If our virtual needs increase, then that is exactly what we would do: scale it up. We can just run everything on it — anything not critical that is fine running on a VM. Right now, we are a very small company. There is plenty of room to grow and I do not expect Proxmox will be exhibiting pushback any time soon.  

How are customer service and technical support?

Customer support is the only cost for the product and it is about $3,000 maximum. It depends on the support plan you choose. There are two different plans. If you want a 24 by seven plan or next business day, that is the difference. The plans are a little different but it is all very clearly laid out on their website.  

Their support is pretty good. Even if you did not want to pay support, the thing that is great about the product is that it is open-source. There are a lot of knowledgeable users nowadays and the pool is growing all the time. A lot of times you can just Google whatever issue you are having and likely come up with the solution to the problem.  

Which solution did I use previously and why did I switch?

We did use a different solution prior to Proxmox VE, and that would be VMware. At this point, we have been able to migrate from VMware completely and we just use Proxmox.  

Before I got here, the company was strictly using VMware for this type of solution. I am not really sure if they looked at other solutions. When I got here I did not even know about Proxmox. I just assumed we were a VMware shop. But after I started, someone had discovered Proxmox and I started reading up on it. It was interesting enough that I started using it. As I did, I thought it felt very familiar. I kept testing and as far as I was concerned I could do everything in Proxmox VE that I was doing in VMware.  

The initial deployment of Proxmox did not really have all of the same features as VMware, but that was kind of the expected in a newer open-source product. They added the other features very quickly. How much the product is advancing is especially apparent with this latest release where it has got the same failover concerns as VMware does. They are called "high-availability" features.  

So now that you can get all the HA (high-availability) features that VMware has, there are not too many major differences between VMware and Proxmox. The only difference is you get it for no cost. It is easy to use, easy to manage, easy to scale, and there are probably going to be a whole lot more and better things coming down the pipe from them. It really has been a great effort on the part of the developers.  

How was the initial setup?

The question of whether it is easy to set up or not really is more like five questions. They are pretty easy questions.  

We have the source on a thumb drive. You launch the system install from the thumb drive and the first question it wants answered are "What is the time zone," "What is the host hostname," and "What is the IP address?" There are three of the questions. With those three questions, you just started the installation on the target server.  

If you want to get running, there are two more important questions. You answer these questions the installer does its job and installs everything you need on your end and you are done. The two questions are "What is your username?" and "What is your password?" You answer those questions and you are done with the installation. You can see it has a high-level of difficulty.  

From the time the setup starts, the total time it takes to deploy everything is about 20 minutes. You do not need an integrator, reseller, or consultant to help you out with the installation. You can set up everything yourself.  

What's my experience with pricing, setup cost, and licensing?

My advice on the pricing is that there is no pricing: it is free. The only thing you pay for is support and it is like $2,500 a year. The support is completely optional. But even the support is absolutely affordable for just about any company in the market. In any case, it is well below the cost of a VMware license.  

What other advice do I have?

My advice to people considering the product is that they have nothing to lose. Run it in a development lab, make sure they are comfortable with it, and make sure that the application that their company runs can support that hypervisor. It should. Then deploy Proxmox and start saving money.  

I have been encouraging former colleagues of mine that are VMware users to start using Proxmox. I suggest they throw it in their development lab and spin it up and start building systems just so they can see the absolute benefits of this product and really enjoy the fact that they can have it as a solution at no cost.  

Proxmox is constantly coming out with updates. If the company you are working for has the appetite to run updates frequently in a production environment you can enjoy frequent releases. They are always looking to add additional features to the product. That is kind of nice. They have a very agile approach to the development of the application itself.  

What people are concerned about is that it is open source. But hopefully, they will start to realize all you have got to do is use the product, they do not have to program anything. It has got the same features that VMware has, but it is not as restrictive as VMware because it is open-source and you can actually build on it if you want to.  

In VMware, the hypervisor, which is called VirtualCenter, needs to live on its own system. It can not coexist with everything else. Proxmox does not have that issue. Proxmox can have everything living on one system. You will want more than one piece of hardware in a given cluster so you can set it up separately if you want to, but the possibility is there to put it all on one box. I think it is a little bit better than VMware in that sense because you have that flexibility.  

On a scale from one to ten where one is the worst and ten is best, I would rate Proxmox VE as a seven-out-of-ten. Ironically, I would rate VMware lower than Proxmox because of the price.

An extremely stable and scalable open-source solution

Pros and Cons

  • "The solution is extremely scalable."
  • "A feature which should be added is the ability to encrypt the main installation."

What is our primary use case?

I have Proxmox VE, which is based on Debian Linux, installed at home. It's part of my virtualization now. It allows one to create  virtual machines in containers. We basically created a web interface. My test environment and pfSense are installed on the solution for building the data center. I am using version seven, which is the latest version that was recently released. I've been working with Proxmox since version two. 

The solution can be used to virtualize environments, as well as for containers, similar to that of VMware, Hyper-V, Nutanix and OpenStack. Proxmox takes a different approach. It provides one single user interface to configure the virtual machines, the containers, the management and everything else. It's based on Debian Linux, using KVM. The web interface replaces the need to deal with the command line. It allows a person to create virtual machines and is very user-friendly. It's an amazing product. 

What needs improvement?

A feature which should be added is the ability to encrypt the main installation. The address cannot be encrypted when installing the solution as an operating system. However, because it's a Debian based project, one can always install Debian Linux, encrypt it and then install Proxmox on top of that.

While my experience with the solution is still very new, there are many features that need to be added for the backup part, not the one involving virtualization. While we are talking about a complete solution, it would be amazing if this issue concerning the backup part were to be addressed. 

For how long have I used the solution?

I have been using Proxmox VE for five years.

What do I think about the stability of the solution?

The solution is really stable. 

What do I think about the scalability of the solution?

The solution is extremely scalable. 

How are customer service and technical support?

I never tried the Proxmox tech support. As it is an open source project, they have a good community online. So, I did not find any trouble googling the issues I faced and finding solutions for them.

How was the initial setup?

The installation takes 30 minutes. It's not that hard, as it is on a GUI. There's an interface to it involving one's country, the email address, password and IP address that one wishes to use. That's it. It will handle everything else.

What's my experience with pricing, setup cost, and licensing?

Because I'm using Proxmox VE for personal use and it's an AGPL license project, I can use it at home for free. Enterprise support can be provided, although I have never tried this and always took advantage of the community subscription. Once I installed the solution, I replaced the enterprise repository to the community one. I don't get all the goodness of Proxmox VE, but that is okay.

What other advice do I have?

I utilize the solution solely for personal use, for my home net. I have a home server in which VMware is installed. I had to reinstall this on a monthly basis, which was a nightmare. One day I came across the solution, installed it into the server and it's been working like a charm ever since. 

They recently also released a backup solution, which is now in its second release. I think they also recently released version two. This backup solution can work with Proxmox to backup the Proxmox VMs. In terms of Proxmox, it really is an amazing product. I can't think of anything critical to say about it, to be honest. One can scale it and it allows for high visibility virtual machines can be replicated. One can do many things with the solution which would  be a nightmare to do in data centers. Proxmox VE makes it much easier to do.

When it comes to the solution, there is much integration involved. It's like it's own ecosystem, as Proxmox was making virtualization platforms and mail gateways before. Now, Proxmox offers its own backup solution. In the past, I would have had to use Veeam to backup the Proxmox virtual machines. Also, the restore wasn't so seamless. But, Proxmox offers its own backup solution for doing agentless backups and restores. It allows for five restores and even instant VM recovery, same as Veeam. It's just amazing. 

We are talking about the native ability to encrypt the storage. Lets say, for example, that I want to install Proxmox on the server, but I want the server to be encrypted. This means that, should I dispose of the hard disk, nobody would be able to decrypt my data.

My advice to others is to dive in straight away. Don't hesitate.

I rate Proxmox VE as a ten out of ten.

Easy to use and supports multi-monitors on multiple VMs in KVM

Pros and Cons

  • "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 Windows drivers could be easier (unlike manually installing Ballon, QEMU and optionally SPICE, VIRTio, etc.)"

What is our primary use case?

We are now running it in full HA production vs XCP-NG and VMWware 6.7u3p We have multiple VMs on 6 hosts for Proxmox, 5 hosts on XCP-NG, and 12 Hosts for VMware.

Proxmox Config: 6X 2697V2 128GB ram each / 24TB SSD for CEPH (HP S700 PRO). XCP-NG Config: 5X2690V3 128GB each/12TB SSD (Samsung 860 Pro).

VMware Config: HP BLADE 12X2690V3 256GB each/2 SAN with 24X1TB SSD (S700 PRO) and total usable 1PB with multiple DAS for storage.

Comparing the CEPH to vSAN is about the same (wasn't running it in production but the performance was greater with a cheap drive on Proxmox, performance with SAS drives is the same).

XO-SAN was a way to mix a whole mismatch of drive and still get good performance but I would doubt the reliability.

How has it helped my organization?

The performance and compatibility are really pushing some users like community organizations to not buy software licenses anymore (why buy a $1000 license for an old appliance when we can get the same functionality for free on another software and still get good performance). Reliability is still advertised for our clients.

What is most valuable?

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). Containers are awesome fo saving a lot of resources (like 100-200mb for an isolated service vs a whole VM (can't run full HA though). It also works on older hardware (unlike VMware) so community clients are able to afford that unlike a new $10000 entry-level server with the config.

It's as stable as VMware or XCP-NG if you have a licence (much cheaper than VMware but XCP-Ng is totally free if you don't need functionality like clustering, XO-SAN, VCenter, etc.)

What needs improvement?

I think the team is already doing 150% on improvements (started from 4.6 and now on the 6.2-6 version and every 3-4 weeks we are given new functions to compete with all hypervisors competitors). Releases are much faster than VMware or XCP-NG but be aware unless you have a paid support licence, then you're a non-production client (updates are tested on you so don't expect 100% uptime without giving it some love).

The Windows drivers could be easier (unlike manually installing Ballon, QEMU and optionally SPICE, VIRTio, etc.)

I would like to get new containers and/or new stuff that, unlike the leader VMware, is so new that it would now lead the market.

For how long have I used the solution?

2.5 years VS XCP-NG and VMware

What do I think about the scalability of the solution?

i think for all SMBs, this is perfect.

How are customer service and technical support?

I have some clients going for the support option (mostly community) but even if the community support advertises no estimated response time, all issues have been resolved on the same day (can't be certified though as they aren't posting if they're actually helping on this plan).

Which solution did I use previously and why did I switch?

We previously used VMware and XCP-NG.

How was the initial setup?

The setup is literraly 10 mins. If you have VLANs or anything it's so easier than VMware.

What about the implementation team?

I have implemented for our team, in fact, we have searched a lot for community organisms and found that like three years ago.  We were testing this solution for 6 months and compared it to our **TO GO SOLUTION (VMWare 6.7).  We have also tested XCP-NG in that same process.

What was our ROI?

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

What's my experience with pricing, setup cost, and licensing?

It is so affordable if you're good with Linux.

Which other solutions did I evaluate?

We also evaluated XCP-NG.

What other advice do I have?

Best free and stable solution on the market for me.

Which deployment model are you using for this solution?

Out-of-the-box, is easy to learn compared to other vendors, and is easy to deploy

Pros and Cons

  • "The feature that I have found most valuable is that its storage container, LVM, and everything else work out of the box."
  • "It could have more security updates such as when a new threat is coming into market."

What is our primary use case?

We use the open-source version of Proxmox for automation and other uses, including LXC containers. We use it for my enterprise applications and to offer our hosted cloud-services.

How has it helped my organization?

Proxmox with Ceph Storage as HCI has given really peace of mind to Management & IT for regular hardware maintenance, with near to zero downtime or no downtime for most of VM & LXC container keeping in mind service running round-the-clock for customer.

What is most valuable?

The feature that I have found most valuable is that its storage ZFS & Ceph, container based on LXC and everything else works out of the box. Additionally, it is a really stable, reliable, and scalable solution.

They have a good road map already in place, so I don't think there are any immediate challenges.

What needs improvement?

I don't have any real challenges about improvement here. (As most IT required features are included and they do have roadmap). Plus API & Command tool is lot helpful.

I personally keep exploring other players and backup/Restore/DR software.

And believe more advance features of backup/restore & DR Data Sync for Ceph  on GUI fronted would be added benefits for users coming from other platform.

On Security/Firewall/Software-Defined-Switch with more advance feature on webGUI would be also more helpful too.

For how long have I used the solution?

I have been using Proxmox VE for more than six years.

What do I think about the stability of the solution?

Proxmox VE is an enterprise solution, it is used daily. Its regular maintenance is normal, the way you would maintain any normal infrastructure. There is nothing special or complex with it. We have a team of five people who maintain it, but there aren't any complex challenges.

What do I think about the scalability of the solution?

My company is very small but I have more than 10,000 users accessing on ProxmoxVE Cluster. We provide the solution to other customers.

How are customer service and technical support?

The thing about this solution is that is so stable I hardly need any technical support.

Which solution did I use previously and why did I switch?

We used Raw Linux Virt-manger for per Server management for VM & LXC before, without any central management.

How was the initial setup?

Everything has a learning curve, steps to watch, understand and explore. But with Proxmox there are hardly any challenges. I don't think the deployment took more than an hour.

What about the implementation team?

Its was inhouse.

What was our 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.


What's my experience with pricing, setup cost, and licensing?

Recently, I have been a Proxmox reseller. I wanted to promote it in India because there is no reseller here. We are trying to promote Proxmox here because being open source it's not popular worldwide, although we have been using it in production for the last more than five or six years. We have been exploring Proxmox for small applications for more than seven, eight years.

Which other solutions did I evaluate?

Tried Xen, but was not comfortable.

What other advice do I have?

With Proxmox VE you get everything in one box, including the ZFS & Ceph storage & LXC container technology. 

Even the support subscription is really good.

It's a wonderful open-source solution. It's out-of-the-box and it is easy to learn compared to other vendors. It is easy to deploy and maintain and you hardly have any trouble or challenges from the software. 

It provides peace of mind for management.

On a scale from one to ten, I would rate Proxmox VE a nine.

Performance and impact are great because of the clusters

Pros and Cons

  • "It has a good performance and you can cluster it."
  • "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."

What is our primary use case?

We sell Proxmox VE solutions to our customers. The workload to help our customers may be the biggest use case to be on the cloud. We use a bunch of statuses, and different ways to deliver databases, and SQL Servers. So, that's the natural way we use the platform on the cloud.

How has it helped my organization?

It has a good performance and you can cluster it.

What is most valuable?

It's more about the clusters. The clusters are pretty much good and have a high performance and impact.

What needs improvement?

For now, we're planning to migrate to another solution because there seems to be a lot of backups that we have set up. We have reviewed Proxmox VE but we want to focus more on our customers. In fact, we have already finished our first deployment and we will receive more features that will go to the cloud.

For how long have I used the solution?

I have been using Proxmox VE for the past five years.

What do I think about the stability of the solution?

You don't have to be very observant. We have maybe three times the hard one, but it seems as if this is an open-source solution that is supported by the community, and it's okay.

If you feel you have the skills to do it, you can go hands-on by yourself to do these deliveries, and it's going to be very useful for the solution. You need to have the training and the right skills.

What do I think about the scalability of the solution?

For now, we are pretty much working on that, but I think someday, we will make it solve another class from our class which is very good because we have an installation. If you start from the beginning, it's the third one, maybe you have the profile, so you will deploy it in maybe four days.

How are customer service and technical support?

So it's what you have to like to go there, but it can work because if you have some problems, you have that resource to go and I found things they will need. They will keep you updated and will help you a lot. So if you ask me, their service is good. The community forum is very technical, and they're quick to respond when they are messaged.

How was the initial setup?

The setup is very easy, but the problem is when you have to customize the solution they're talking about more episodes. You have to be more hands-on to have a very good draft, it will be more helpful to have a very good delivery.

What's my experience with pricing, setup cost, and licensing?

For the price, performance is going to be the first takeaway we can offer to our customers.

What other advice do I have?

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. Though we intend to go with a third party to look for another solution, we hope they will fix that in the next release.

The work panel is very good for intake. It's very easy to use and you can scale from other areas which is not a very technical way, so you can use them, including the panel. They can manage their integrated solutions, and that's very good because it's the thing that you want to scale. If the customer wants to operate a downgrade and do something with Proxmox VE, that is what will take you there. You can integrate Proxmox VE with other solutions. Proxmox VE is one thing if you want to start with cloud deployment.

Great two-factor authentication with a good interface and backup

Pros and Cons

  • "The backup service, which was released recently, and that we are already using, is wonderful."
  • "We have only command lines for a management application to remove sites. The solution needs a proper GUI."

What is our primary use case?

We use the solution to host virtual machines, such as: SQL Server Database, Active directory domain services, web services, general cloud applications, and some virtual machines or containers for development and testing purpose. Specially the preference for containers is due to the easly development when the only basic operational system is required istead of fully hardware virtualization (kvm).

We heavly use replication resource to assign some garantine to critical virtual machines wich could run eventually on other sites or hosts, in case of broken internet links, hardware issues or even hacker attacks (many thanks to ZFS working with PVE-ZSync feature that allow planning a standback period of retention snapshots, quickly failover and fallback of virtual machine storage)

How has it helped my organization?

It is high availability resources, replication and live-migration (on cluster envirioment). We don't have significant problems with hardware issue or maintenance schedule, because with ZFS, Cephs or other shared storage incorporated in Proxmox technology, it´s possible to migrate virtual machines to other hosts with almost zero downtime.

What is most valuable?

1) The two-factor authentication: for security reasons!

2) PVE-Zsync: wich allows replication outside clusters, with snapshot retention for quickly failover and failback (by incremental syncs)

3) Large documentation and "How-To" on the wiki page;

4) Many usefull integration: APIs, Active Directory;

5) ACLS, Groups e User Managment: Allows to set and customize permissions.

6) Proxmox Backup Server: Assertive Incrememtal Backup Solution for realible local backups or remote with encryption support! That's perfect.

7) Built on Debian based Kernel, very stable distro

What needs improvement?

1) PVE-Zsync GUI implementation - This is a very important tool, it could delivery the more advantage in comparision to Xen Orchestra and Microsoft Virtual Machine Replica Service.

2) Central Cluster Administration: The possibility to manage many clusters sites in "one only page" instead of oppening many browsers tabs! IT Cloud companies as us, usually need to access diferent clusters sites, I think it's good idea to centralize the administration GUI for companies that own two or more cluster sites!

3) In connection with my suggestion number 2, the possibility to create a "farm cluster". In few words, the possibility to move virtual machines (live or not) among diferents clusters sites separated by WAN links. Actually, PVE Cluster is realible on local links, due to multicast or udp rings, but in some scenarios when a entire cluster site needs to be put offline (eg, for maintenance or internet issues), a virtua machine migration to other cluster that belongs to the same "farm" but in other region will increase the "value" of Proxmox simular to Microsoft Azure Site Recovery ou Amazon. That will make my evaluation increase from 8 to 9 or even 10!

For how long have I used the solution?

Since 2014

How are customer service and technical support?

The technical support is the very complete. I don't  have a subscription, because the support that we need for our applications and solution are available on the Proxmox Wiki However, for big companies we recomend the Proxmox subscription for getting a first class support and best pratices.

Which solution did I use previously and why did I switch?

Microsoft Hyper-V on situation thats requires Outside Migration (see my comment 3 on the question: what areas could the product or service be improved)

How was the initial setup?

The solution is very easy to set up and implement. It's not complex. We can put a single host or even a Cluster only line in less than one hour! 

What about the implementation team?

Not yet!

What's my experience with pricing, setup cost, and licensing?

Proxmox delivery more cost X Benefits in comparision to VMWare and Citrix Xen. It could be improved in future for more benefits in comparison to XCP-NG and  Microsoft Hyper-V

Which other solutions did I evaluate?

Citrix Xen-Server and XCP-NG

Which deployment model are you using for this solution?

On-premises

Open source, easy to install, and works well with Linux

Pros and Cons

  • "The solution is open source and free to use."
  • "The availability of the solution could be a bit better."

What is our primary use case?

I primarily use Proxmox for training in university. I use its virtual environment.

What is most valuable?

The availability of the platform is okay.

If we compare Proxmox with VMware, VMware provides an environment with a client. And Proxmox provides us an environment with a web client. Most important things for me. And Proxmox uses a middle person with an improviser.

Some items that we use within this solution are not available in other virtual environments.

The solution works well with Linux based systems.

There's a SPICE protocol that's very useful in managing aspects of Proxmox.

The product is pretty easy to install.

The solution is open source and free to use.

What needs improvement?

The availability of the solution could be a bit better.

For how long have I used the solution?

I've used the solution for about three years or so.

What do I think about the stability of the solution?

Sometimes I see the stability can cause little problems. I've noticed that, when I use, I merge two, three, or four virtual machines, and when I merge all of these machines at the same time, we have some running slowly. Even if I use the virtual environment I see things running slowly sometimes.

What do I think about the scalability of the solution?

The scalability is okay. If a company wants to scale it, they can.

How are customer service and technical support?

I've rarely contacted technical support. I have a pretty good competence with Proxmox at this point in time.

Which solution did I use previously and why did I switch?

We also use VMware or sometimes Citrix as well. We use a variety of virtual environments and compare them. I use them as learning devices for my students.

If you look at the overall market, VMware is the best in terms of offering and popularity, however, I personally prefer Proxmox and will continue to use it and advocate for it.

How was the initial setup?

The installation is very easy. It's straightforward. It's not complex. This is due to the fact that it's an environment that depends on Linux with the version of the kernel in Linux.

When we install it the environment is so easy, we just have to put the image of the system and we choose the mode of installation. It's quite simple.

When we are in the environment, we just need to create an instance of a VM.

What's my experience with pricing, setup cost, and licensing?

I use the open-source version of the solution. We build on a general public license. We don't pay for using the service. For us, as an open-source version, it's free. I'm not sure if there are other versions that cost more and what the pricing is. I've never looked into it.

What other advice do I have?

I'm just an end-user of the solution. I don't have a business relationship with Proxmox. I use the product in my classroom as a learning aid.

I'd recommend the solution. It's been an invaluable learning resource for myself and my students. It works well and shows off the potential of virtual environments. I use it often for my classes and with my students as a teaching device.

On a scale from one to ten, I would rate this product at an eight. I would only give VMware a higher rating. It's definitely at the top of my list in terms of technology in this area.

Switched from Citrix XEN and EMC VMWare: No downtime when node needs service but web interface could be simplified

What is our primary use case?

It is implemented in several Private Cloud Data Centers, from 5 to 16 nodes, from 256 GB RAM to 1 TB RAM, all using Supermicro Systems, running SQL servers, Application Servers ( SAP, Prothevs and some tailored Apps developed in house ) VDI and Files Repositories . all smooth and trouble free .

How has it helped my organization?

With live migration, there is no downtime when any node needs service or upgrades. Plus, when I need more memory, I just allocate it; more disk space? same. It is possible to administer almost anything remotely, now it takes months till a customer needs a weekend visit to service something, before Proxmox, it used to happens once a month!

What is most valuable?

Live migration :

Is simplifies the daily work, and reduces the downtime to nearly 0 .

Clonning and Snapshots :

Verry useful for development testing and backup .

Histogram about i/o, memory, CPU and network usage :

Helps to find the issue when some VM are running in some kind of bottleneck .

What needs improvement?

Mostly simplify web interface, simple things like the use of right mouse button to change VM attributes, make it more intuitive, but it is just cosmetic improvements, the core functions are all there.

Version 6.x improved the support for Containers to the PRO level .

For how long have I used the solution?

re than 10 years, since version 1.6 all the way to version 6.2 

What do I think about the stability of the solution?

Never had any issue with stability, even in the very earliest stages of development...

What do I think about the scalability of the solution?

Not for now, the 16 nodes per cluster limit have been removed in the 5.x release !

How are customer service and technical support?

Customer Service: OK, in fact the little we've used it, the site documentation was really good.Technical Support: Same as above.

Which solution did I use previously and why did I switch?

Yes, Citrix XEN Server and EMC VMWare Server. I left Citrix for security, there are too many "black box" in the binaries that cannot be audited. In the VMWare case, for licenses politics, it uses a "per socket" schema that punishes high density servers with 2 or 4 sockets .

Is is the tool of choice used in the entire Facebook infra-structure, so it must be "at least" good enough .

How was the initial setup?

The first test was a little complex, in the time of the 1.4 version, but since the 2.0 version it is extremely simple, takes less then an hour to deploy a node and connect it to an existing cluster.

The 6.x release made things even easier, most maintenance tasks are now in the web interface

What about the implementation team?

I am an IT consultant, and I do everything myself (with my team, we are 4 people!)

What was our ROI?

Outstanding, worth every single cent spent on it!

What's my experience with pricing, setup cost, and licensing?

The deployment itself cost nothing, it is Opensource software! The monthly subscription costs 17 euros per node, and it covers anything we needed so far...There are more options, but it is more then our customers needed until now .

Which other solutions did I evaluate?

Several, From Red Hat to Ubuntu, and everything I can find with a Google search, I spent 6 months with these research and tests!

The Facebook contract came well after this tests .

What other advice do I have?

Do it! The simplicity will surprise you!

Which deployment model are you using for this solution?

Private Cloud
