An introduction to Azure Dedicated Hosts | Azure Friday

Due to corporate compliance and
regulatory requirements, some organizations must run their
virtual machines on isolated servers. This can be a roadblock
when trying to move these workloads to a public cloud. Ziv
is here to show us how Azure dedicated host can clear the way
today on Azure Friday. Hey everyone, Donovan Brown here
with another episode of Azure Friday. I’m here with Ziv and
he’s going to teach us all about Azure dedicated host so
first simple question. What is an Azure dedicated host so it’s
a new service. We just announce it public preview Azure
dedicated host is a new service from the Azure computing, where
we offer customers physical servers isolated for their
workloads. So normally if I ever say spin up a particular VM it
might be on a server physical machine that’s Also, running a
VM for you, correct and now today. We’re saying I don’t want
anyone else. Running VM S on this machine, except myself and
that’s what this is offering correct in fact. This is a
blocker for some of the customers with talk to so we
introduced this knew service Azure dedicated host where
basically the VMS are the same VM so the same management. API
tools monitoring agents. You have everything just keep
running you get the flexibility to control which VM. Goes to a host site playing
Tetris, so once I have a dedicated host. Can I can I run
more than one VM on that host or is it always one VM per host?
When I set it up this way. You know the point is to run
multiple VMS on a dedicated host. In fact, we offer you to
run small and large VMS as long as they are from the same
family, on the same host so you can run your database on 32V.
CPU’s kind of DVM and next to it smaller. VMS for the application
itself gotcha gotcha, but now, what I do know for a guarantee
is only my VMS are the ones running their correct that so
the first reason the first benefit for Azure dedicated host
is the compliance by shared nature of isolation. Again, this is not a bare metal
offer this is still platform managed by Azure. So you get the
security. The patches the management. The networking stack
all like elsewhere in Azure. The second aspect is the control.
Becaus, you can place and stack specific. VMS you control
exactly which VMS running on the host. Another aspect of the
control is the benefit of controlling the Azure initiated
maintenance so be cause. You own the entire host. You can specify
that everything Azure? Does it could even be a tiny blip of
like a second pause. You want to control it, you will get a
maintenance window of up to 35 days in which you can say apply
this maintenance on that host apply it on that host I can do
this. But I don’t have to do this. I could just say please
take care of everything. Don’t wanna know because those
changes shouldn’t impact me anyway, correct we’ve seen customers running. Workloads
were even 2 seconds is considered downtime interesting
so perfect and 3rd benefit of using Azure dedicated host is
the Azure Hybrid benefits, so this is bring your own license. Of windows and sequel to Azure
using Azure dedicated host where you benefit the
unlimited virtualization where we bill. You just for the
physical cores that you actually consume on the host
awesome, so How do I set it up then? So you need to start by
Provisioning, a host group and the host group could be in a
single availability zone or spread across the region and
then within a host group. You create host now each host has
its own full domain. So it’s like virtual machines within an
availability set a full domain is mapped to Iraq and also
applies to the underlying storage infrastructure. In other
words, 2 VMS running to host in 2. Full domains will be served
from 2 different storage steps. It’s not a colocation
constrained or anything like that. And a host has Askew
so this. Q defines the type of VMS. The family
initially we started with a DV3 and EV3 and the
generation so type. One is the generation. We
currently offer and in the future. We will be offering
newer larger different vendors probably running
supporting the same VM S. Ready for demo I would like
to see all right, so we’ll start with the portal.
Although you can do everything using CLI
PowerShell or just on templates and we will start
by creating a host group. And a host group is just
another resource does this live inside of a resource
group or above. A Resource Group. This leaves inside the
Resource Group. In fact, I will call it Azure Friday
Resource Group My Resource Group. Great. And whoops sorry. Validation error no it’s kind of
misleading alright, so let’s call it demo host group. Gotcha so we name, The Resource
Group. But we didn’t give them credentials are that
information. Then we’ll go to us E 2 and let’s say we will pick
one of the availability zones available and by eating
indicating full domain count. I’m actually telling Azure I
don’t really want to control full domains within my group, I
can set it into 2 or 3 and now we should be good.>>And then what I would do is
assign the VMs to that…>>hold on. We just created a
group now. I need to create a host and the host is
another Top entity? Which. We will just go and pick
the group. We just created Azure Friday
Resource Group and give the host name Azure
Friday host one. OK and we will. Created in the same. Region. In our case, it’s yeast us too. OK. We will pick a family I
mentioned that we support either. DS V3 or SB3. Where
do I get a description of? What those 2 things need. I
don’t know which one I’m supposed to go in our
pricing page. You’ll see exactly which vendor CPU
generation? How many CPUs and how much memory you have
on those hosts. I will place it in my host group
and I am done now when I go. Next step is let’s go and try
and create try to create a virtual machine in that host so
will pick an open 2. Then we’ll go to the same
resource group. And the host has the
ability to run both Windows and Linux
Correct. I don’t have to pick one or specifically
as your Friday VM. Everything is still being
created in the background that’s OK. US E 2. And you see the default actually
is a D2 S V3, it’s from the same family that’s OK. Oh, because I picked a
availabilities on one for the group. I need to pick the same
availability zone for the VM. Sorry forgot that no problem, so
that was only one I guess. Gotcha and then the advance
should be able to pick up the host for me, so you see I have
one group in that zone and I have one host and basically that
will take my VM and place it in my host gotcha and then all
those that I want associated I would simply come here and set
this up. But just because I’ve set up a host or host group
doesn’t mean the next. VMI provision has to be in there, I
can just click. This link and it has to be a normal. In fact, if
you have the flexibility, then you can actually take a running VM. And really redeploy it to
dedicated how is summer moving it from area to area there is
down time you actually take it and play sure sure sure just
curious now. You said this downtime? What’s the down time
you have any estimates so well. If you do it. Manually then it’s
kind of up to you. But you need to start the VM stop the
allocate the VM and then move it to your dedicated host catcher
so take the time plan for it and it should just work again using
CLI or portal or or. On complete great you are saying
that you have you talked several times about the different
options that we have? Is there a blog post or something that we
can go to learn so we just announced August 1st. In fact,
Azure dedicated host appears now as a product under compute. Yup, right there right there, so
this could be your starting point, an if you are fan of
using arm templates. We already published getting started sample
perfect for using dedicated host this. In fact, is pretty smart
template because what it does is. You provide the number of zones.
The number of full domains in the number of hosts and this
template will actually evenly spread hosts within the full
domains and zone that you ask for so it’s a good template
because you can learn a lot about using some are magic so
for example, you see this is the resource group and the name of
the resource group is automatically generated and the
zone use conditional statements. Provided number of zones or not,
it’s pretty cool simply awesome. I appreciate this well. Thanks
for showing us that did this is very cool stuff. We’re learning,
all about Azure dedicated host here on Azure Friday.
