HyperV Nested Virtualization Announced for Container Support
-
Microsoft's Blog has announced the upcoming HyperV Nested Virtualization in order to support containers for Windows in the near future.
-
That's pretty interesting that there working on containers for nested hyper-v.
I'm curious where a case could be made to use Hyper-v nested inside of Hyper-V for a production scenario. The article it's self says to not use it for production. Although that might just be because it's a very early release.
Hrm...
-
@DustinB3403 Think about being able to run your own Hyper-V instance with all your VMs and infrastructure set up the way you like it on Azure or something like that... Suddenly your whole infrastructure becomes portable.
-
I don't use Azure (XenServer is my preference), the one Hyper-V server was completely setup ass backwards by our MSP, and is in production, so yeah, lets not go down that road.
Portable, how so? Because you can simply export the primary VM, which includes all other VM's configured on it?
Or am I missing your point?
-
@DustinB3403 I would think more portable as in live migration... You don't have any generators at your main site and the power company needs to take you down for 24 hours. You could then Migrate your Nested Hyper-V infrastructure to Azure for a day and not have to scramble to find generators and such, and you don't even have to scramble to bring things back up because they never go down.
That would be the way I see it. As I said, I may be completely out of my mind, but that is what I envision with containers.
We'll ignore the completely badly configured Hyper-V setup that you have now.
-
Well I guess that makes sense. But if you have an Azure solution, why would you also host the solution on site?
Why not just leave it on Azure. I'm going out on a limb and thinking Microsoft has a much more robust and reliable data center then most businesses.
-
@DustinB3403 Cost of hosting the entire infrastructure on Azure 24x7? Chances are if you are big enough need to host Azure for a day, you probably already can afford to host your entire infrastructure there anyway.. .

Yes, instead of moving VM by VM from one place to another, you can move your datacenter from one place to another.

In the example, Azure is the DR site. Lots of companies want the speed (network latency) and cost of an on premises solution but cannot afford a DR facility. Azure is that DR facility. This is actually a major talking point of Azure sales. They work hard to make this a viable option for their offerings.

Indeed they do, our recent outages aside, but it isn't cheap and if your issues are primarily network based or you have need for fast networks or you just don't need that robustness you can offset it this way.
-
Is the cost of being able to use Azures service something that can be "enabled" with an email? I would assume it to be a monthly reoccurring cost.
And does the price get reduced if you aren't actively using it, but have the option to use it on a whim?

Like all IaaS cloud, you pay by them minute or hour for capacity. So when not used, you don't pay.

That's the definition of cloud
-
Azure, Amazon AWS, Rackspace, Softlayer, Digital Ocean, Vultr, etc. are all the same. Capacity is by minute or hour (you can choose larger blocks with AWS for discounts) and so you literally pay only for what you use. The idea of cloud is that you can elastically grow or contract as your load changes so that you are paying for only what you need rather than for your maximum needs all of the time.
-
Ah well at least it's cost-viable, rather than being a flat rate minimum per month plus usage.
Sorry it's still early, not thinking very clearly.

Very cost-viable. The issues are that you need to get that infrastructure up there in the case of an outage and that could be a bit of a problem since you presumably are offline and your entire infrastructure might be pretty big.
-
So one has to ask, if you have a site wide unplanned outage but do have access to Azure, how do you get your Hyper-V data to them so you can at least get to a functional state?
Just play out the different "DR scenarios" and options. As I'm already thinking of 6 different questions.
- How do you get your hyper-v infrastructure to Azure in the event of an unplanned outage?
- Do they have some solution to keep a "ready-to-go" state of your hyper-v network/

Generally you would keep it synced there all of the time.

You can copy to cold storage there.
-
So question 3 how do "you" work if you have an unplanned outage, even if Azure is running your VM Fleet?
This is obviously a rhetorical question, and doesn't need an answer.
