Explanation

To ensure the reliable performance of the applications running on the set of virtual machines, you need to use Azure Scale Sets. Azure Virtual Machine Scale Sets service helps create and manage a group of VMs behind a load balancer. The configuration of these machines must be the same, and they should run on the same base OS image. The VM scale sets can automatically increase or decrease VM instances depending on the scaling rules and resource demand. Scale sets provide high availability for your applications. You can use scale sets for large-scale services, like compute, big data, and containers. https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/overview
