As you all might be aware VMware is hiking prices again. (Surprise to no one)
Right now Hyper-V seems to be the most popular choice and Proxmox appears to be the runner up. Hyper-V is probably the best for Windows shops but my concern is that it will just become Azure tied at some point. I could be wrong but somehow I don't trust Microsoft to not screw everyone over. They already deprecated WSUS which is a pretty popular tool for Windows environments.
Proxmox seems to be a great alternative that many people are jumping on. It is still missing some bigger features but things like the data center manager are in the pipeline. However, I think many people (especially VMware admins) are fundamentally misunderstanding it.
Proxmox is not that unique and is built on Foss. You could probably put together a Proxmox like system without completely being over your head. It is just KVM libvirt/qemu and corosync along with some other stuff like ZFS.
What Proxmox does provide is convenience and reliability. It takes time to make a system and you are responsible when things go wrong. Doing the DIY method is a good exercise but not something you want to run in prod unless you have the proper staff and skillset.
And there is where the problem lies. There are companies are coming from a Windows/point in click background who don't have staff that understand Linux. Proxmox is just Debian under the hood so it is vulnerable to all the same issues. You can install updates with the GUI but if you don't understand how Linux packaging works you may end up with a situation where you blow off your own foot. Same goes for networking and filesystems. To effectively maintain a Proxmox environment you need expertise. Proxmox makes it very easy to switch to cowboy mode and break the system. It is very flexible but you must be very wary of making changes to the hypervisor as that's the foundation for everything else.
I personally wish Proxmox would serious consider a immutable architecture. TrueNAS already does this and it would be nice to have a solid update system. They would do a stand alone OS image or they could use something based on OStree. Maybe even build in a update manager that can update each node and check the health.
Just my thoughts
I suppose thats the difference between Windows admins and Linux admins. Windows admins are used to click their way though things with fancy gui's and wizards :)
I've been using Proxmox professionally for years now, and not once did i have s problem i could not fix myself. But i'm used to solve problems myself by "digging in deep". Ofcourse it helps that i've been using Linux (mostly Debian) since 1996. There are plenty of guides around to teach how Debian works. Windows admin's who make the switch just need to take the time to read them, watch the video's, do the research.
The only skills we where born with are the basic survival skills. Everything else is learned along the way. So was using Windows, and so is using Linux.
But thats just my opinion :)
The problem isn't necessarily the GUI. The problem is there are a lot of admins who don't understand what is happening under the hood. I've talking to people of all ages who have no understanding of how basic things like networking work. I've also talked to to people of all ages that have a deep understanding of the system.
The biggest takeaway is that to be a good admin you need to understand the details. Don't be afraid to dig in. Either dig in, move to management or both
Exactly! :)
I manage macOS, Linux AND Windows. In the end, they're all the same. Its software that needs management.
And how many of the environments you have left behind became an unmanageable mess when the company couldn't hire someone with your skillset? One of the downsides to this sort of DIY infrastructure is that it creates a major dependency on a specific skillset. That isn't always bad, but it does create a risk which business continuity planning must take into account. This is why things like OpenShift or even VMWare tend to exist (and be expensive). If your wunderkind admin leaves for greener pastures, your infrastructure isn't at risk if you cannot hire another one. The major, paid for, options tend to have support you can reach out to and you are more likely to find admins who can maintain them. It sucks, because it means that the big products stay big, because they are big. But, the reality of a business is that continuity in the face of staff turnover is worth the licensing costs.
This line, from the OP's post, is kind of telling as to why many businesses choose not to run Proxmox in production:
Sure, none of those technologies are magic; but, when one of them decides to fuck off for the day, if your admin isn't really knowledgeable about all of them and how they interact, the business is looking at serious downtime. Hell, my current employer is facing this right now with a Graylog infrastructure. Someone set it up, and it worked quite well, a lot of years ago. That person left the company and no one else had the knowledge, skills or time to maintain it. Now that my team (Security) is actually asking questions about the logs its supposed to provide, we realize that the neglect is causing problems and no one knows what to do with it. Our solution? Ya, we're moving all of that logging into Splunk. And boy howdy is that going to cost a lot. But, it means that we actually have the logs we need, when we need them (Security tends to be pissy about that sort of thing). And we're not reliant on always having someone with Graylog knowledge. Sure, we always need someone with Splunk knowledge. But, that's a much easier ask. Splunk admins are much more common and probably cheaper. We're also a large enough customer that we have a dedicated rep from Splunk whom we can email with a "halp, it fell over and we can't get it up" and have Splunk engineers on the line in short order. That alone is worth the cost.
It's not that I don't think that Proxmox or Open Source Software (OSS) has a place in an enterprise environment. One of my current projects is all about Linux on the desktop (IT is so not getting the test laptop back. It's mine now, this is what I'm going to use for work.). But, using OSS often carries special risks which the business needs to take into account. And when faced with those risks, the RoI may just not be there for using OSS. Because, when the numbers get run, having software which can be maintained by those Windows admins who are "used to click their way though things" might just be cheaper in the long run.
So ya, I agree with the OP. Proxmox is a cool option. And for some businesses, it will make financial sense to take on the risks of running a special snowflake infrastructure for VMs. But, for a lot of businesses, the risks of being very reliant on that one person who "not once [had a] problem i could not fix myself", just isn't going to be worth taking.
Proxmox earns most of its money by giving proffessional support.
If this is your concern, then you can buy support directly from Proxmox, just like you could from VMWare. So if i ever where to leave the company, and there's noone with my skillset (which i think is terrible management, having your company depend on the skills of one person). My boss can sleep just as calmly as before, knowing we pay Proxmox for support.
Unlike VMWare, paying for support from Proxmox will likely get you answers. Hell, they fix problems for unsubscribed users in a pretty timely manner.
I fought with VMware for years to get bugs fixed or even acknowledged, it eventually drove me out of the space because they were pretty much the only solution for inhouse virtualization and they did. not. give. a. fuck. about SMB.
I'd take a community/supported hypervisor long before a VMware ever again. I've never felt frustrated trying to get something FOSS fixed like I have with companies like VMware and Microsoft.
That hasn't been a thing for a decade. Any time you run into an issue or need to do something on mass you fire up PowerShell
I know plenty of Windows admins who still dont use Powershell as much as they could/should. Which i think is odd, since Powershell is so much better, but i suppose its not easy to change old ways :)
God damn Linux admins are pretentious.
Thankfully i don't consider myself a Linux admin. So i take no offense.
