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) More details: https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/overview

Let explain with Azure perspective.....Suppose we put two VMs into Availability Set, then Azure will set up VMs to two different racks so that if the network, power, etc. failed, then only one rack will be affected. Below diagram shamelessly copied from internet and hope this helps you to understand how VMs are put under multiple Fault Domains through Availability Set so that if one node down, other node can still give service.

Explanation: Virtual machine scale sets are Azure compute resource that you can use to deploy and manage a set of identical VMs. With all the VMs configured the same, scale sets are designed to support true autoscale, and no pre-provisioning of VMs is required. So it’s easier to build large-scale services that target big compute, big data, and containerized workloads.

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! Ben Martin
