How to use Azure proximity placement groups #Azure #SAP #Latency

When moving to Azure or building new infrastructure workloads latency is important and where do I find the numbers of how do I configure it for the best and what is the difference between Azure Availability groups or Azure Availability zones or do I need Azure Site Recovery. Well as a Consultant IT depends.

Availability Sets

Availability Sets takes the virtual machine and configures multiple copies of it.  Each copy is isolated within a separate physical server, compute rack, storage units and network switches within a single datacentre within an Azure Region.

When you create your virtual machine you can specify the Availability Set, you can’t change it or move it in or out of an Availability Set after creation.  If you wanted to make changes you would need to start again and recreate the virtual machine.  Availability Sets only apply to virtual machines, they can’t be used for any other type of resource within Azure. So Local Datacenter redundancy.

Availability Zone

The next level of availability for your virtual machines within Azure is Availability Zones.  With Availability Zones utilized your acceptable downtime a month moves to less than 5 minutes as you’ve got a 99.99% SLA.With Availability Zones you are starting to use zone aware services. Your workload will be spread out across the different zones that make up an Azure region.  An Azure region is made up of multiple datacenters and each zone is made up of one or more datacenters.  Each datacenter is equipped with independent power, cooling and networking.

You Can imaging when using this there could be some extra latency between the VM’s it all depends on the zone where you are deploying this but that can be tested .

In many Azure regions, the number of datacenters has grown. Azure datacenter latency could be tested here. https://www.azurespeed.com/Azure/Latency

In the next setup I use a Azure VM both in west europe and we test the latency in the same region between vm’s. The tool I use is Latte

On the Server sender we placed the remote receiver IP

Here on the receiver we use the local vm IP and after the test the latency is shown. this is a common setup. If we want to improve this or to make sure that these numbers are not getting worse we need to change the setup.

516 Latency(usec)

When running SAP latency is important, Azure has an option that is called Proximity placement groups. An Azure proximity placement group is a logical construct. When a proximity placement group is defined, it’s bound to an Azure region and an Azure resource group.

A single Azure resource group can have multiple proximity placement groups assigned to it. But a proximity placement group can be assigned to only one Azure resource group.

Proximity placement groups offer co-location in the same data center. However, because proximity placement groups represent an additional deployment constraint, allocation failures can occur (for example, you may not be able to place your Azure Virtual Machines in the same proximity placement group.)

When you ask for the first virtual machine in the proximity placement group, the data center is automatically selected. In some cases, a second request for a different virtual machine SKU may fail since it does not exist in the data center already selected. In this case, an OverconstrainedAllocationRequest error will be returned. To troubleshoot, please check to see which virtual machines are available in the chosen region or zone using the Azure portal or APIs. If all of the desired SKUs are available, try changing the order in which you deploy them.

In the case of elastic deployments, which scale out, having a proximity placement group constraint on your deployment may result in a failure to satisfy the request.

Graphic for proximity placement groups

If you want to use availability zones together with placement groups, you need to make sure that the VMs in the placement group are also all in the same availability zone.

In this sample we gona make an Azure proximity placement group and place Two VM’s in it As an sample I also use a Azure Virtual desktop machine

How to create an Azure proximity placement group, In the azure portal type proxi and the Azure proximity placement group are there.

Select Create , add resource group and pick a name that fits your name convention

Add some tags and that is all or do this in powershell

$resourceGroup = "rg-proxim-demo-weu-01"
$location = "West Europe"
$ppgName = "ppg-avd-sap-01"
New-AzResourceGroup -Name $resourceGroup -Location $location
$ppg = New-AzProximityPlacementGroup `
   -Location $location `
   -Name $ppgName `
   -ResourceGroupName $resourceGroup `
   -ProximityPlacementGroupType Standard

Adding a VM to the new created Azure proximity placement group is selecting the configuration of the VM and add it to the VM. In my case I have an availability set added to my VM. So I must upgrade the entire Availability set to add the Azure proximity placement group

Now that we added the Azure proximity placement group to the VM we need to run the same test again.

Both machines are already in the same availability set that is now added with the Azure proximity placement group

testing from outside the avail from a B2 vm to a D2v3 sku

running this on a d4ds_4 as this is in the av set I need to choose what is in the limit of this set so bound to the VM sku

as you can see it really depends vm sku type what kind of latency you will get but basically it is lower when you are using Azure proximity placement groups

Interesting to see in the PowerShell commands from the Azure proximity placement groups there is also an ultra section, this is currently in preview but can give you even better results but keep in mind you can’t fix it with just one setting check your chain and fix that instead of fixing just one link.

-ProximityPlacementGroupType

Specifies the type of the proximity placement group. Possible values are: Standard or Ultra

$resourceGroup = “rg-proxim-demo-weu-02”
$location = “West Europe”
$ppgName = “ppg-avd-sapultra-02”
New-AzResourceGroup -Name $resourceGroup -Location $location
$ppg = New-AzProximityPlacementGroup -Location $location
-Name $ppgName -ResourceGroupName $resourceGroup
-ProximityPlacementGroupType Ultra

New-AzProximityPlacementGroup: The subscription is not registered for private preview of Ultra Proximity Placement Groups.

Think I need to do some research for this to add my subscription to this preview. Hope it was helpfull thanks for visiting my blog.

Effective March 31, 2021, the Azure portal will no longer support Internet Explorer 11. Start using the new Microsoft Edge for speed, security and privacy

Well on every server or Windows device there is the Internet explorer and prepairing some server workloads you may need some browser and may need to connect to Azure. using an old browser is always an bad idea.

When setting up a new server what ever version it is I always remove the IE icon and install Msedge this works fine and gives me a more secure feeling.

Microsoft Edge

Opening the Azure portal with IE you will see a warning about non supported browser.

Microsoft Edge

With the option to download the Edge directly

Microsoft Edge

The portal still opens in IE but using some functions are not working sample as anything that will use HTML5

Microsoft Edge

Official Download links for Microsoft Edge Stable Enterprise

I’m not 100% sure it’s final but anyone who wishes/wants can test it.

Microsoft Edge Stable Enterprise

X64.msi
http://go.microsoft.com/fwlink/?LinkID=2093437

X86.msi
http://go.microsoft.com/fwlink/?LinkID=2093505

MicrosoftEdgePolicyTemplates.cab
http://go.microsoft.com/fwlink/?LinkID=2099616

MicrosoftEdgeIntunePolicyTemplate.cab
http://go.microsoft.com/fwlink/?LinkID=2099617

macOS.pkg
http://go.microsoft.com/fwlink/?LinkID=2093438

Blocker Toolkit to disable automatic delivery of Microsoft Edge
https://docs.microsoft.com/en-us/deployedge/microsoft-edge-blocker-toolkit

So when you want to auto mate this the following lines could be used to install quickly Microsoft Edge

#Create temp folder
New-Item -Path ‘C:\temp’ -ItemType Directory -Force | Out-Null

#Install Edge
Invoke-WebRequest  -Uri "
http://go.microsoft.com/fwlink/?LinkID=2093437" -OutFile ‘c:\temp\MicrosoftEdgeEnterpriseX64.msi’
Invoke-Expression -Command ‘C:\temp\MicrosoftEdgeEnterpriseX64.msi /quiet /norestart’

This will install Microsoft Edge and you can set this in a powershell script and in the GPO that way all new servers will get Microsoft Edge.
