create multiple Azure VMs in single powershell script parallely - powershell

I am able to create Azure VM using powershell.
I have to create 4 VM's parallel.
Does any feature in powershell to do create multiple VMs parallel ? Something like background jobs or call the same function for all different VMs using threads kind of ?

Have you considered VM Scale Sets? They automatically deploy VMs in parallel in a highly available configuration and make managing those VMs much easier (overview doc here: https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-overview). You can of course deploy a scale set or a bunch of VMs from powershell (doc for deploying a scale set via powershell here: https://learn.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-create-vmss), but the Powershell commandlets require you to specify lots of related properties (e.g. virtual network, subnet, load balancer configs, etc.). The Azure CLI 2.0 (which you can use on both Windows and Linux!) gives lots of good defaults. For instance, in Azure CLI 2.0 you can do this single command to create all of your VMs in parallel:
az vmss create --resource-group vmss-test-1 --name MyScaleSet --image UbuntuLTS --authentication-type password --admin-username azureuser --admin-password P#ssw0rd! --instance-count 4
(taken from the documentation here: https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-create#create-from-azure-cli)
Hope this helps! :)

No, there is no built-in Azure powershell cmdlets or features enabling you to do so. You can create your own routine for that. I'm using PS jobs for that.
You need to use Save-AzureRmContext and Import-AzureRmContext to authenticate powershell inside jobs or use any form of automated login.

Thanks all, I have solved my issue using PS workflow parallel and sequence features. Achieved it.

Configure azure VM using terraform and ansible using azure cli and without ssh keys in azure pipelines

I'm using Azure Pipelines with terraform to create a dynamic infrastructure (unknown number of VMs, NIC..) in Azure.
I also tried to use Ansible in a separate stage to configure my VM, but I can't because the work is complicated because I had to create ssh keys and use them by Ansible, so I want to configure my Azure VM without using SSHAkey and use Azure CLI instead, I know that Ansible is agentless and use SSH to communicate with VM but I hope there is a module which allows us to configure VM using Azure CLI?
Alternatively, if anyone already has an existing project like this one and is well organised & less work, I would be grateful.

Automate CosmosDB emulator setup

I would like to create scripts to prepare dev CosmosDB emulator with all the databases, containers and index policies. Is there a way to do this?
I saw there is some PowerShell commandlets, but those are just for administrative tasks only. Cosmos Db CLI doesn't seem to have any of needed capabilities as well.
There is great PowerShell module CosmosDB which can help in many ways automating emulator. The only struggle and challenge for me would be to have some kind of automatic transition from Terraform scripts (container names, db setup, indexes and etc) to PowerShell.

How do I perform this command in azure powershell on my hdinsight cluster?

I have managed to use this command on my hdinsight when I connect via ssh using azure cli, however I want to create an azure powershell scrip that will run the following command but I can't figure out how. I have tried searching for it online but can't find anything.
sudo -HE /usr/bin/anaconda/bin/conda install pandas
In this documentation see a section titled "Apply a script action to a running cluster from Azure PowerShell". You will need to take your script and put it in blob storage and then have the cluster execute that script ok each node using an HDInsight script action. The nice thing about script actions is that when they do cluster maintenance patching the underlying servers and need to take down a node and bring up a new node (or if you scale the cluster) then it will run the script action on any new nodes.

How to run a group of PowerShell scripts in Azure

I have a group of interdependent .ps1 scripts I want to run in Azure (trying to set up continuous deployment with git, Pester unit tests, etc., as outlined in this blog). How can I run these scripts in azure without needing to manage a server on which those scripts can run? E.g., can I put them in a storage account and execute them there, or do something similar?
Using an Azure automation account/runbook seems to be limited to a single script per runbook (granted, you can use modules, which is insufficient in my case).
Note that I need to use PowerShell version 5+ (I noticed Azure web apps and functions only have 4.x.)
Thanks in advance!
You were on the right track with Azure Functions. However, given that you need v5+ of PowerShell, you may want to look at Azure Container Instances (ACI) instead. It's a little different approach (via containers), but should not impose any limitations and will free you from having to manage a virtual machine.
Note: At this time ACI is in preview. Documentation is available here.
There is a PowerShell container image available on Docker Hub that you could start with. To execute multiple scripts in the container, you can override CMD in the docker file.

Can Start-Process be used in Azure Automation?

When I try to start a process using Start-Process on Azure Automation, it doesn't run and remains Idle. Is it possible to run processes on Azure Automation?
There are 2 ways to run Azure Automation jobs - in Azure workers and in Hybrid workers on your premises. I suppose you are trying to run a job on a Hybrid worker, so you should be able to start a process on the machine. There are some security restrictions on the processes with GUI, so you will not be able to see GUI for your process, but for the process per-se - it will be created, I just tried it myself:
start-process
To get more information on running jobs in Azure, please refer to https://azure.microsoft.com/en-us/documentation/articles/automation-starting-a-runbook/
Detailed article about running jobs on Hybrid Workers is here: https://azure.microsoft.com/en-us/documentation/articles/automation-hybrid-runbook-worker/
