What is the Upside to VMware to the SMB?

Speaking of, did you calculate the effective cost of your Scale licensing ie price from Scale - effective cost of Dell hardware etc?
I have not, that would be an interesting study to do. It's a little difficult as it wouldn't be licensing, but support. But if you lump the two together for a general comparison it would be meaningful.

We do a lot of voice stuff and whilst our termination gear is not virtualised, most of our customers who do choose to virtualise their endpoints are using VMware. They don't have problems once we tell VMware to reserve resources for that VM. The customers that do have problems are those who virtualise onto EC2, but thats a totally different issue.
Issues on EC2? We do a lot of telephony on Rackspace, which is Xen with OpenStack, and haven't had issues for years, not even before they were open stack. I'm very surprised that EC2 isn't as good or better.
VMware definitely can handle audio processing now. This was ~2003 when they were lagging behind. I know that by 2006 they still weren't handling it well. But that's when we stopped looking at them for several years. We moved to them, I want to guess, around 2009 and by that time telephony was fine. They had advanced a lot in the interim.

Indeed. When I first looked at Nutanix I was shocked at the pricing, that was until I subtracted hardware & labor (install and migration). We didn't end up proceeding with Nutanix due to concerns over their closed review policies and lack of guarantees on performance.
Scale pricing would be extra interesting seeing that you would also exclude hypervisor pricing as well as (I think it uses KVM internally?)

Yeah, Nutanix burned a lot of bridges permanently with that stuff. Once you know that they are faking their reviews and data there is no way you want to do business with them. Just way too much to go wrong. I've even had a little pressure put on from them to back off on disclosing that to people and I've never done business with them (nor would I.)

That's correct, it is KVM.

There are some inherent issues with EC2 but they rarely cause issues with SMB customers. The real issue with EC2 is the elasticity it offers customers. There have been numerous times customers have had a cloud consultant downsize their pbx instance to save a few dollars, only for it to cause issues later on. At least with on-premises virtualisation resources don't change that often.

A "cloud consultant"? Where does that person come from?
The elasticity of EC2 is supposed to be in spinning up other VMs, not constantly resizing existing ones.

The cloud naturally <grin>. In essence its usually a potential MSP doing an audit and offering to save the customer $x.

Agreed, but Amazon's online advisor tool, makes it too easy for people without proper understanding to perform actions. That being said the ability to terminate a VM, reattach the ESB to a new instance and spin up is quiet useful. If only Amazon would allow you to annotate an instance with "requires min 2 cores, 2gb ram"

So not an EC2 issue, a company doing foolish things and/or hiring someone who doesn't know what they are doing to do foolish things. They might do the same thing on local resources too.
I thought that this was some kind of automated, Amazon provided tool that I did not know about

I have all that power to be foolish with local resources, too. And I use it often. We tune memory very tightly, for example, just because we can.

Just Trusted Advisor and the wrong people using it

The "wrong people" being the key issue. Any top command will cause the same issues to happen even on physical hardware.

@scottalanmiller Just thought of another upside. I think ESXi manages swapping better. Every vm has a preallocated swap file at the hypervisor level equal to its assigned memory. Meaning if you overcommit memory, and you run out of host memory you will begin to swap at the hypervisor level . The virtual machine doesn't know a swap file is being used and just the memory access suddenly got slow (ie true memory virtualisation). The swap file always exists ensuring that storage is more or less guaranteed.
With Xen memory overcommit seems to be a bit of an after thought, with only allowing balloning (via DMR) within the virtual machine and forcing it to use its own swap (if provisioned) within the virtual machine on the virtual disk. This is not only slower but also make the machine misreport its memory usage to tools like munin.
I think this was one of the reasons why Amazon disable balloning in EC2. It exposes too much information to the virtualised machine.

Absolutely, VMware remains the general technology leader. No question there. Everyone plays catchup with few exceptions, one being PV and PVH in Xen that no one else can touch, and MirageOS, but the real question would be, in the SMB how many people are swapping on their VMs, and how important is hiding details if they do?
In the enterprise on massive scales, yes, there can be some huge advantages here. But this seems like a niche case in the SMB. The cost of VMware Essentials alone would be more than the total memory budget of an SMB. Use the money to buy enough hardware to avoid swapping and suddenly the performance advantage goes from nominally in VMware's court to dramatically in everyone elses', right? A normal SMB only has around 64GB - 128GB total server memory across all systems. $500 from not needing an up front VMware license would be enough to double that and still save money, and I don't see many SMBs running out of memory and swapping anyway.
-
It has been half of a year and I am circling back around. No question that VMware has some unique advantages, but also it seems pretty clear that very few of these typically make sense in the SMB market (things like improved swap handling don't pay off when the additional licensing cost could have purchased more memory to avoid swapping, for example.) So only very specific deployments benefit from most of those things.
Now that XenServer 7 is out and Hyper-V 2016 is nearly out, how is VMware holding up in the SMB space? Are there new advancements to put VMware back onto the map, or have they fallen farther behind?
-
@scottalanmiller I kind of look at it slightly a different way... In Aus, the essentials license costs $1,025, for 3 hosts and 3 years of support. Which to me is fairly cheap, esp given that you get phone support.
Therefore, one could rephrase the question as, should I pay $100 per year per host for the market leader. However, its not as simple as that....
If SMBs want VM based backups, then most likely will look at something like Veeam, which is ridiculously expensive. in comparison the the hyper-visor license. $3600 for 3 hosts.
So I think the real question how much will my entire infrastructure licensing costs be, between Xen and VMware platforms.

market leaders are normally a bad thing... Cisco, Lenovo... that's where you pay too much and don't get good service. VMware is actually exceptionally good for a market leader, but it isn't market leading that makes them good. They manage to remain good in spite of it.

But that is available for free with XenServer. So I think remains an ancillary concern. Yes, Veeam is very, very expensive, no doubt there. But I think that that just adds to the concerns about the VMware ecosystem, that the things that you want or need are all extra. You are always paying a premium to get what is free and included in the other products.

Sounds like $4,600 compared to $0.
Support is a factor, but very few SMBs use VMware support, I don't think, and even fewer use the Essentials Plus license that gets them that. Most go for Essentials which does not come with support.
If, for some reason, you need support AND need to pay for it up front, VMware Essentials Plus is not too horrible - but leaves you with a lot of limitations. How unlikely would it be for someone that feels that support is that valuable to also not have qualified people staffed that wouldn't need support and/or would find having more than three nodes under a single pane of glass valuable?
I think that there is serious merit there, but that it hits an extreme niche. If you need support for your hypervisor, something else is almost always wrong. And if you can be limited to just three hosts, while still needing support and big time features, I would guess that you are in the massive minority.

Ah, just realized, you said Essentials in Australia. It is similar cost in the US but comes with zero support. So you get nothing that XenServer doesn't come with for free. Less, actually, since there is good free community support with XenServer to a level that Vmware doesn't really have. Both have some, of course.
People often mention support with Essentials but at least in the US, it's a myth. Only Essentials Plus has support.
