Terraform Lab: Azure Load Balancer with Availability Set

Lab scenario

We are tasked with provisioning an Azure Load Balancer for the HTTP and HTTPS requests with an availability set as the backend pool. We are also tasked to output subnet IDs and the load balancer's frontend IP. Lastly we will keep the tfstate file in a separate storage account remotely.

Objectives

In this lab, we will:

• Task 1: Provision the required lab environment.
• Task 2: Provision the load balancer.
• Task 3: Output subnet IDs and load balancer's frontend IP.
• Task 4: Configure the tfstate file remote storage.

Instructions

Task 1: Provision the required lab environment

In this task, we will create:

• a resource group named rg1,
• a virtual network named vnet1,
• two subnets named frontend_subnet and backend_subnet,
• a storage account,
• two virtual machines named vm0 and vm1 in an availability set named as1.

Task 2: Provision the load balancer

In this task, we will create the load balancer with the name lb1. In order to create the load balancer, we will need to create:

• a frontend public IP,
• a backend pool (our availability set),
• a health probe for HTTP,
• a load balancing rule for HTTP,
• a health probe for HTTPS,
• a load balancing rule for HTTPS.

Task 3: Output subnet IDs and load balancer's frontend IP

For this task, we will create an outputs.tf file with the content subnet IDs and load balancer's frontend IP.

Task 4: Configure the tfstate file remote storage

For this task, we will use an already created resource group and an existing storage account with a container named terraform.
