When to use VMWare over free hypervisors?

When is VMWare ever the recommended option for a new setup?? Is it ever?
I'm not considering it or anything, I'm just curious.
if free = free of charge. The only reason is: your are asking a supplier to keep care of your virtualization and they have no skilled people on other than esx. Better to change supplier if you can.
free of charge is way more then ok for virtualization and still requires other (paid or free) components to run backups/replica/HA.

@bnrstnr Never.
Wrong.
VMWare ESXi can be the correct fit when you need a specific function from that environment. The cost of the solution isn't expensive if your business requires those features.

example?
-
Now many times a business feels that they require a specific feature, but in reality don't understand it, and use the system incorrectly.
Thus they are paying for something without the benefit that was planned.

"I absolutely need vMotion to ensure my systems are up 100% of the time, I have a server infrastructure of 3 or more hosts."

VMware does have a specific set of features that may be a requirement for a lot of businesses. But many businesses simply mis-evaluate what they actually require.
So they buy when they shouldn't buy.
Sure they get support from VMware in those cases, but the money was incorrectly spent.

vMotion is live migration + HA? Don't know if it works with SAN or without. but for live migration at least vSAN is required for 100% uptime: share nothing live migration can't work. You can accomplish this other ways:
- KVM has ovirt+gluster
- hyper-v has native starwind
- starwind seems to be available outside windows
- Xen has HA Lizard - I think.
don't know about the setup time and labor, this could be the only discriminant. in Italy vMotion + vSAN is so expensive that I can pay for setup of other solutions and stay in budget.
Maintainance costs is probably another factor. But here others win hands down. RTO and RPO can't be discussed because this is HA.
Can you share some real cases of why you think you have to ditch others for VMWare? just curious. This has been my hypervisors week

Wat
What is being described here is the requirement of high availability and I've never seen it get brought up and then ML reply with "vmware is the right solution". It'll be interesting to see the replies to this thread

If you are talking about HA: 100% uptime , istantaneous RTO and RPO yes: usually you can to without.

The difference is that VMWare has a solution for 100% uptime with "VMware VMotion (which) enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity."
That is HA without the need for a vSAN or other Highly available storage. The hypervisor has this built in.
-
The question is only able to be answered with if the business requires specific functionality of Esxi, beyond what the free version of esxi offers.
If all the business needed was to run a virtual machine the business would be better suited with any other hypervisor.

... isn't vMotion then exactly the same as in Hyper-V 'Move' then? I can move VMs in Hyper-V from one host, to another, without shared storage, and with 0 downtime.
vMotion sounds just like the move option in Hyper-V. Nothing special. If HostA crashes, does vMotion move the VM to another host instantly without any downtime to service and no shared storage? - Now that would be different...

It does.
If the host crashes? So... I have 5 VMs... the host dies.... NOW! vMotion brings them up on host2 instantly, with the exact same in memory and app running etc... no boot?

There are other features as well, but that is the most common feature that many businesses say they need. Literally 0 downtime systems.
As if they are wall street stock exchange

Now that is a nice feature
didn't know that. Impressive with no shared storage. Even in windows cluster, if a node dies with a running VM, when it comes up on Node2... it boots from fresh and lost memory.So, what the price tag for vMotion?

You can research the pricing, I think it's in the $5000 range per year.

Everything I've read about vMotion (though never used it) makes it sounds like Host A would have to be up to do a live migration (hence the "Live Migration"), if host A crashed, the state would already have to be present on Host B to fail over to... no?
