Even now, Hyper-V still doesn't scale well.. good for 1-3 hosts but anymore it's not great.
What aspects are you seeing with it scaling? I don't use it, so have no experience with scaling issues or lack thereof. What happens to it at four and more hosts to be a problem?

The folks that are familiar with Hyper-V from its early days will look away and run straight to VMware without even checking out what other players are in the game because of the Brand Recognition. They are concerned about the learning curve (lack of familiarity) that would come with having to learn another hypervisor that is not as widely known (among their circles).
Even now, Hyper-V still doesn't scale well.. good for 1-3 hosts but anymore it's not great.
I'm asking just out of curiosity, as I'm currently about to build out a 3-node Hyper-V cluster (for VDI) here soon... What makes it not scale well?

It's the "no one ever got fired for buying IBM" crowd. Which is just a cover up phrase for "hoping to not do any analysis and I know my boss doesn't know the difference so I don't care."
We let our AS/400 team go a good while back and removed it. So yes they have..
Oh they do, even internally IBM fired an entire site partially based on their reliance on IBM gear and IBM's inability to deliver and support their own gear resulting in massive outages.

@DustinB3403 Remember that you're referring to Spiceworks, who seems to get a LOT of funding from VMWare. Why else would you have an entire community section dedicated to VMWare and none of the other major offerings, especially the free ones considering who they claim to serve.

I love ESXi Free. And I believe you can backup VMs now using Unitrends Free (albeit with the need to install agents on the VM). So for a single host with 2 VMs (as per the SW link), I'd use ESXi.
So there you go. I don't care about brands and my boss is never going to sack me, I just really love ESXi. Feel free to slate me here!

ESXi free is pointless. Why would you even consider it? You're crippling yourself for no reason.

Crippling myself in what way?

Nothing is really wrong with that. It's just that when you do move into areas that you need to license ESXi, the cost compared to Hyper-V and XenServer just doesn't work out.

It literally has no usable tools built in at the hypervisor. If you want to backup the VM's you're forced to use an agent on each VM.
Which is a huge pain in the ass. Plus all of the hardware restrictions built into the free version.

Well, no. You can back up files, not the VMs. ESXi has no backup API, so you can treat the VMs as physical machines and back them up using an agent inside of the VMs but you give up the ability to do a hypervisor backup which is what everyone means when they say that ESXi doesn't have backups. Unitrends doesn't get around this, just lets you use agent. Backup Exec and every other old school backup system doesn't get blocked by VMware, if they use an agent inside the VM, the VM can back up its own files as usual.
You list how you get around one ESXi limitation. But you only "mitigate why its bad" but never mention why it is good. You said that "so... you'd use ESXi" but only gave "less negative" but no positive reasons.
What are the reasons that makes it better, rather than just "less worse?"

Fewer options, in your specific case, is the biggest thing. With two VMs and zero desire to take hypervisor level backups (if that is true that you place zero value on that feature which most people consider almost essential) you lose pretty little with ESXi. But you do lose some things that might matter sometime down the road:
- Web interface
- Unified interface if you add another machine / single pane of glass
- Backups inside your platform instead of using another tool
- Agentless backups / platform images for rapid restores
- VM motion between machines in cases of hardware migration
- Storage motion in cases of moving storage if needed
- Update and patching tools (does ESXi Free have any? I'm not sure.)
- Zero license effort
- Zero license tracking
- Zero "now eligible for VMware audits" that we've seen to be horrific (did you read that EULA?)
- No limits on scale should you need to grow tomorrow
None of those are big except maybe the license ones, but they are all little risks that do exist that don't need to.

Can you restore a Unitrends backed up VM to a different host? If you can't then I can see that that would be a severe limitation.
The the reason I would choose ESXi is that I am familiar with it.
I wouldn't be crippling myself by choosing ESXi free because if I did want to use those things sometime down the road then I could simply switch to a different hypervisor that does offer those features. I wouldn't be tied to ESXi financially because I'm using the free version.

Yes, and you can fire Windows backups up right on the Unitrends device itself, too.
Of course it can go to a different host, wouldn't really be a backup otherwise. It can be restored to different hypervisors entirely or even to physical.

I have to admit i'm a ESXi person, but only because I can install ESXi and be installing VM's within 30mins. (Backups are an issue)
Hyper-V I have to configure a workstation to be allowed to manage the host (god help me if there's a domain involved lol)
Xen - I admit, I just don't know enough about it, but from my last test it was a nightmare getting install isos onto the server to install onto VM's. -

I can't even get the license squared away that quickly on a new VMware build!

But why build up a ESXi platform, if you simply wanted to change later if you needed more features?
Why limit what features you have today when you might need them tomorrow?

Xen - I admit, I just don't know enough about it, but from my last test it was a nightmare getting install isos onto the server to install onto VM's.I can get Hyper-V and Xen up in the same amount of time I can get ESXi setup. Each has a very simple installer.

Having done both, it is essentially identical to ESXi Free but without the licensing risks and complications. So... way easier.
XenServer you just pop in the ISO, same as ESXi Free, and it is ready in a few minutes. Easy peasy.
For ISOs, you don't load them at all. You just share out a folder from your desktop with them and that's how it does it. VMware makes you upload them before use, XS uploads them as used.

Time to install XenServer again me thinks
(any tips on using ISO's to install into VM's??) -
