Creating the required infrastructure with Terraform

Our goal was to build a scalable LAMP stack, so we will define a VM scale set using the apache-webserver image we created and a single VM with the mysql-dbserver image. A VM scale set is an autoscaling group of VMs that will scale out and scale back horizontally based on traffic, similar to how we did with containers on Kubernetes.

We will create the following resources:

• A new resource group called lamp-rg
• A virtual network within the resource group called lampvnet
• A subnet within lampvnet called lampsub
• Within the subnet, we create a Network Interface Card (NIC) for the database called db-nic that contains the following:
  • A network security group called db-nsg
  • A VM called db that uses the custom mysql-dbserver image
• We then create a VM scale set that includes the following:
  • A network profile called webnp
  • A backend address pool
  • A load balancer called web-lb
  • A public IP address attached to web-lb
  • An HTTP probe that...
