What are virtual machine scale sets in Azure

A virtual machine scale set allows you to deploy and manage a set of auto-scaling virtual machines. You can scale the number of VMs in the scale set manually, or define rules to autoscale based on resource usage like CPU, memory demand, or network traffic. An Azure load balancer then distributes traffic to the VM instances in the scale set. In this quickstart, you create a virtual machine scale set in the Azure portal.

 

I hope this helps!

Hi,

The number of VMs automatically increase/decrease based on critera. All VMs are load balanced. Can scale upto 1000 VMs.

 

When you have demand that should fulfill folling criteria:

1. Auto-scaling of VMs

2. High Availablity

3. Need multiple VMs of Same Type (like 10 Windows instances of VM)
