While deploying a VM in Azure. If I choose a region ex. "Central India" which is having support of Availability zone, but I am not choosing that option while deploying. Then what will be the default zone in which the VM get deployed?
I think it will be zone 1, please correct me if I am wrong.
I tried to reproduce the same in my environment got results like below:
I deployed virtual machine and I choose region as Central India by default it's support of Availability zone as zone 1 without selecting an option of zone like below:
To confirm in portal, once vm deployed it supported as zone 1 like below:

I'm deploying a global networking solution and using Terraform as my IaC solution. I have ExpressRoutes, VPN Gateways, Vnet-to-Vnet connections etc.
I've deployed a VPN Gateway in Azure North Central US and now when I come to deploy and IP address for it I can't. By default I use Zone-Redundant availability zones. Ie. Zone 1, 2 and 3. When I try to deploy an IP using Terraform, I can't use any of the available options - no zone string list, no single zone, not the No-Zone or None parameter. All I get is an error from the MS API saying the available zones for the region are ''. It's literally empty.
If I deploy it manually then get the IP properties of the address it shows the zones as an empty array. Are MS experiencing issues right now? I find it incomprehensible that the North Central US zone which is the regional pair of South Central US (which has 3 availability zones) has...no zones. I'm confused. Could someone share their experiences please, and advise whether this is a temporary issue. I scoured the internet and found nothing. I'm normally working in the European Azure regions so this is the first time I've used this particular one.
Currently, there are no availability zones present for North Central US in Azure but as per the document here, availability zones will be coming soon for North Central US. As of now, these are the Azure Regions with Availability zones.
I am using Azure Powershell cmdlets to reserve the current IP of my running Windows VM instance. To test it, I created a new VM, ran it up, then ran New-AzureReservedIP with the -ServiceName tack so it knows reserve teh current IP. It worked a charm! I shut down the machine and it reallocaed the same IP address on startup.
Now if I do the exact same thing on an actual production Windows VM I get the below error. Could it be that this machine has been running for about 3 years and is not supported for some reason? Syntax is correct as my initial test and in the same location etc..
BadRequest : Cannot reserve the ip of deployment xxxxxxxx
Has anyone else had this problem?
If this cloud service is 3 years old it is quite possible that you are using an affinity-group VNET to host the VM. It is not possible to reserve an IP address from such a VNET. The following is documented:
Reserved IPs are only supported in regional VNets. It is not supported for VNets that are associated with affinity groups. For more information about associating a VNet with a region or an affinity group, see [About Regional VNets and Affinity Groups][2].
I need to create two DS virtual machines within the same cloud service. In the existing portal this is very easy, however in the preview portal there appears to be no options to set the cloud service when creating a VM.
The problem is that the existing portal cannot create DS virtual machines, or virtual machines with premium storage. Whilst the preview portal can create DS virtual machines, but cannot create virtual machines within a cloud service.
I have tried to create virtual machines in the existing portal as a D series VM, and then upgrade with the preview portal to a DS VM but this option is not available.
I am hoping I am missing something obvious.
A central feature of a cloud service is a shared DNS name which provides a VIP and a load balancer. In the preview portal this capability is exposed through a shared DNS name. Give your second VM the same DNS name as your first VM.
I want to add traffic manager to my azure virtual machine.I created total 4 virtual machine .2 in east us region and 2 in north Europe region.but when i want to add the both 2nd machine in the availability set respectively i didn't find the other machine which i want to add.
so help me to configure this
Availability Sets and Traffic Manager are not related subjects in Azure. When you create your two virtual machines in each Region make sure to add them to the same Cloud Service. This will enable load balancing and enforce availability set behaviour across the two VMs.
Repeat this in the second Region.
Then use Traffic Manager to route traffic using a Failover strategy (if appropriate) to the public interfaces of the Cloud Services.
While this is about using Web Roles you might find this blog series useful: http://blog.kloud.com.au/2014/11/03/deploy-an-ultra-high-availablity-mvc-web-app-on-microsoft-azure-part-1/
Availability sets are not the same as the traffic manager.
Availability sets are per region (that's why you only see 2 machines)
Add a traffic manager through the portal and select the VM's in both regions.

I have update the deployment by uploading new package in the azure management portal. But by using this Ip address of cloud service is change. How It could? As I havn't deleted old deployment I had just choose the option "Update Production Deployment" in azure management portal . Anyone have any solution please?
Did you change the size (not number of instances) of any virtual machine since the previous deployment? That would be a reason for the virtual IP to change.
