Learn how terraform providers enable azure resource management, including provider blocks, provider requirements, and provider configuration, with init, plan, apply, and destroy, plus the .terraform.lock.hcl for version locking.

Learn to define provider requirements in Terraform with required_providers and configure the azurerm provider. Explore the features block for Azure deployments.

Create a resource group using azurerm_resource_group, run terraform init, validate, plan, and apply with -auto-approve; then destroy with -auto-approve and clean up state files.

Explore Terraform multiple providers, creating region-specific configurations with East US and West US providers, using aliases to assign resources per region and control behavior.

Configure multiple azurerm providers with aliases, including provider2-westus, to deploy two resource groups in East US and West US, using provider meta-arguments, and run init, validate, plan, and apply.

Explore how the dependency lock file protects upgrades from 1.44.0 to 2.64.0 for the azure provider, and create myrg1 and a random_string with the random provider.

Learn to create an Azure storage account resource in Terraform using azurerm with provider 1.44.0, dynamic naming from random_string, and cross-resource references to resource group and location.

Use a Terraform dependency lock file (.terraform.lock.hcl) to pin providers, then init, plan, apply, and upgrade while preserving 1.44 versions and avoiding automatic upgrades.

Explore Terraform resource syntax, including resource type and local name, and learn how arguments, attributes, and meta arguments shape resource behavior in Azure deployments.

Learn to create an azure subnet, public IP, and network interface with Terraform, linking subnet id and public IP id to the network interface within a virtual network.

Explore the four Terraform resource behaviors—create, destroy, update in place, and destroy-and-recreate—illustrated with Azure cloud constraints. Learn how these behaviors affect the terraform state and the apply process.

Demonstrate a create resource workflow in Terraform: init, validate, plan, and apply to provision a resource group, virtual network, subnet, public IP, and network interface.

Explore how Terraform state tracks real world Azure resources and their configuration bindings. Learn when the state file is created, what it stores, and why remote backends matter.

Explore Terraform resource behavior, focusing on update in place and destroy-recreate workflows demonstrated on a virtual network with environment dev tag changes.

Implement Terraform settings and provider blocks for Azure in the first real-world demo. Configure Terraform CLI version, required providers versions, and backend, while defining the Azure RM and random providers.

Define and use terraform local values to name expressions once, reference them across resources, and centrally manage common_tags and a resource_name_prefix for many resources.

Use the Terraform random provider to generate a unique random_string for Azure resource naming and create a resource group with a prefix-based name.

Create a web tier subnet and a matching network security group, define inbound and outbound rules (inline or via separate NSG rule resources), and associate the NSG to the subnet.

Learn to create azurerm_network_security_rule inbound rules for a web subnet NSG using Terraform for_each with a ports map, handling port 80, 443, and 22, and manage creation order with depends_on.

Define vnet output values in Terraform to print the virtual network name and ID, plus subnet and NSG outputs, across root and child modules, with remote state data sources.

Define and override Terraform input variables with terraform.tfvars to set environment, resource_group_name, resource_group_location, and vnet and subnet values for your Terraform deployment.

Execute Terraform on Azure to build a four-tier VNet with app, web, db, and bastion subnets, create and verify NSGs and rules, then destroy resources with auto-approve.

Provision an Azure Linux virtual machine with Terraform, creating public IP, network interface, and security group, and bootstrap an Apache web server in a four-tier network.

Generate rsa 4096 ssh keys for an azure linux vm, secure private key with proper permissions, and configure a static standard public IP in Terraform for the VM.

Create a Linux VM network interface with azurerm_network_interface, configure ip_configuration with a subnet reference and dynamic private IP, link to a public IP, and consider a network security group.

Review the vm nic network security group setup by associating a network security group with the virtual machine nic, mirroring the subnet nsg pattern used earlier.

Create an Azure Linux virtual machine resource with Terraform, configuring name, location, and network interfaces. Pass the ssh key via file function and custom_data for the sample app.
