When to use VMWare over free hypervisors?

vMotion appears to copy the state of a VM from host A to host B, while keeping the VM "live", if host A crashed while running 5 VMs, as stated above, how could it fail over to host B instantaneously in the same exact state?
Agree. I think Dustin missed my point. vMotion offers little more than the standard move feature in the free hyper-v.
-
There are other features as well, but vMotion and memory state moves are big items that ESXi has, which might make it the correct solution for a business.
Don't get hung up on the 1 item I've mentioned as the only thing ESXi has.

If comparing free VMWare and Hyper-V, then definitely Hyper-V... because free VMWare is almost useless compared, as it's lacking so many useful features and benefits that Hyper-V has for free.
If comparing Hyper-V Free and paid VMWare, then you get a lot more with VMWare than free Hyper-V.
If comparing Datacenter Hyper-V with System Center vs VMWare paid, then you really need to do some serious evaluating. Do you already have Datacenter? Do you already have SC?
I'm assuming not, you said new install, so lets assume no VMWare of any type, no Hyper-V of any type, no System Center, no Windows or licensing of any type... In that case, you can't be big enough at that point to really need more than the free Hyper-V.
But it depends on a lot of things, obviously. If it's all from scratch, perhaps just Hyper-V Server 2016 and a bunch of Linux VMs will do the trick. You don't really need to pay for VMWare until you have hardware that requires it, or need features that are more cost effected or more beneficial than from HYper-V Free or Hyper-V Datacenter and/or System Center. It takes a lot of work evaluating the business and what's the best fit.

From the whitepaper, there needs to be shared storage for this... which makes sense.
"First, the entire state of a virtual machine is encapsulated by a set
of files stored on shared storage such as Fibre Channel or iSCSI
Storage Area Network (SAN) or Network Attached Storage (NAS).
VMware’s clustered Virtual Machine File System (VMFS) allows
multiple installations of ESX Server to access the same virtual
machine files concurrently." -

But that one thing is nothing more than what Hyper-V free has, so it was a poor thing to have mentioned as something that sets VMWare above others...

"I absolutely need vMotion to ensure my systems are up 100% of the time, I have a server infrastructure of 3 or more hosts."
I interpreted this as something somebody might say to justify using VMware, though it may be the incorrect decision... Maybe that's not what @DustinB3403 meant by it at all

VMWare is awesome.
You really cannot beat VMWare. It is the best thing out there.But the cost to obtain it is high because until you grow bigger than a few hosts using vSAN or internal storage, there is no point to paying for it.
The SMB almost never needs it.

It was an ad-hib attempt as to what a business evaluation of their needs are. Where literally the business cannot have downtime for even a few seconds.
VMware has this kind of capability, it just cost money to get it.
And 99.999% of businesses don't require these kinds of features.

But hyper-v can also do this...
Its more design than buying VMWare. -

Its more design than buying VMWare.Hyper-V can't do it without 3rd party software and solutions. The difference with ESXi is you'd have a single point of contact for everything (ESXi). If you wanted these kinds of features in Hyper-V you'd be looking at StarWinds and they'd be your point of contact, assuming you were using the software and not their appliance.
If it was the appliance, they'd be the only people to reach out too.
-
You also have to ensure, when using VMware, that your license includes things like vMotion and the HA failover stuff.
Hyper-V has host Replicas. I'm not sure what it's called in KVM and Xen / XenServer.
But all of the other Hypervisors include all the bells and whistles without any need for a license.
-
Which 3rd party solutions adds complexity, and can lead the the blame game.
There is value in ESXi, but it's not something easily justified for a lot of businesses.

No. You could use hyper-v on its own and match the availability of VMWare site-for-site, with good design. For example, I could use haproxy with multiple IIS servers, VMs, all sitting on multiple hosts, connection to a SQL Server using failover cluster services for the database (no shared storage needed) with multiple lines in etc...
Different design - yes. Less availability than that one same site running VMWare - no.

And your dependency chain is way longer in this setup. The complexity goes through the roof as well. Which while it may be doable, doesn't mean its practical.
At that point you might as well just license ESXi and tell your systems to pool (across multiple sites). Project done.

That makes sense why it's typically not a recommended solution as a lot of us are SMB. I have very little exposure to VMware. Definitely not enough to understand it's strengths and weaknesses. Valuable information.

Why way longer? Two VMs for HAProxy in failover, one on nodeA, one on nodeB, 2 x IIS sitting behing them, one on nodeA, one on nodeB, sql server clustered, one nodeA, one nodeB... not difficult. Just as much reliability as having multiple servers with VMWare at 5k a pop. With VMWare, i'd still need two SQL servers for cluster. I'd still need two IIS, and i'd still likely want haproxy to make sure the traffic will failover between the IIS too...

@Jimmy9008 I'm done with the topic. Please investigate ESXi and how it manages the individual hosts and enabled HA there in.

^ where did I argue? I was asking an actual question... from the quick search I did it was 5k or so per server, maybe not exact... didn't realise I had to provide a detailed quote for a reply on ML!
Chill and have a beer fella - its Friday.

This is the product right?
£4712 with VAT... not far out of the 5k I said no?
So where are you saying I'm wrong here?
