How to Create virtual machine scale set in Azure

In this article, I will explore how to create virtual machine scale set in Azure. A virtual machine scale set permits you to deploy and manage a set of identical, auto scaling VM. We can scale the number of virtual machines in the scale-set manually, or specific rules to auto-scale based on resource usages like memory demand, CPU, or network traffic. An Azure load balancer then distributes traffic to the VM instances in the scale set.

Create a Load Balancer

Azure load balancer disseminates incoming traffic among healthy VM instances.
Create a public Standard Load Balancer by using the Azure portal. The public IP address and name we create are automatically configured as the load balancer’s front end.

1- In the Azure search box, type load balancer and then pick Load balancer.

2- Select + Add

3- Create load balancer wizard, In the Basics tab,
