Azure Virtual Machine Scale Sets are tightly integrated with Azure Load Balancer, Azure Autoscaling, Azure Monitor, and custom images. They support both Windows and Linux virtual machines.
A virtual machine scale set is a way to run many identical virtual machines automatically without managing each one. It grows when demand rises and shrinks when demand falls.
Steps
You create a template of how one virtual machine should look.
The scale set uses that template to create many copies.
A load balancer sends traffic to all machines.
When traffic increases, more machines are added.
When traffic drops, extra machines are removed.

A Virtual Machine Scale Set (VMSS) is a group of identical, load-balanced Virtual Machines (VMs) that automatically scale based on demand.
I will use this guide to walks through the step-by-step process to create a VMSS using the Azure Portal.
Step 1: Sign in to the Azure Portal
Open your browser and go to Azure Portal.
Enter your Microsoft Azure credentials and Sign In.

Step 2: Create a Virtual Machine

Open Azure Portal, search virtual machine and hit enter

Click on +Create and choose virtual machine.
Create new Resource Group: Here I name mine scalesetVM-RG
Provide basic details, virtual machine name, Region, Availability option, Operating system:
Follow the screenshot to get exact details.

After virtual machine have been installed, let increase the login time-out from 4 minutes to 30 minutes so that we cannot be kick out why working.

Drag the to the end until it reach 30. Click on save.
We’re done with virtual machine creation.

Step 2: Create Azure Compute Gallery
In Azure portal, search bar, type Azure compute gallery hit enter
Follow the basic steps shown in the screenshot.

Click +Create

Under Project details, provide the Resource Group name, drop-down and select scalesetVM-RG
Provide instance name, select region, you can follow the screenshot step-by-step guide.
Click next
On the sharing Tab, select the first option Role Base Access, Control (RBAC)

Click #Review+Create#

Step 1.

Step 2. Provide basic details

Step 3. Click Review+Create

Step 1.

Now that we have created Azure Compute Gallery, navigate to virtual machine, click on the virtual machine name. Follow the screenshot below.

Step 2. Click on capture drop-down and click image

Provide basic details as shown in the screenshot.

Step 3.

Click Review+Create

Observe the VM will automatically stop/shutdown to begin creating the image
I captured the image of my virtual machine to deploy my virtual machine scale set (VMSS)

Let’s go ahead and create Virtual Machine scaleset
In Azure portal in the search bar, type virtual machine and hit enter
Click on the virtual machine name and expand it.

Step 1. Click +Create icon

Select Virtual machine scaleset
Under project details, drop-down and select Resource Group and choose scalesetVM-RG.
Give your scaleset a name: Azurevmscaleset
Under Orchestration mode: leave on flexible by default. I Follow the screenshot to complete the task. Click on Review+Create
