What is this?

ARM Templates Overview is infrastructure as code for repeatable Azure environments.

Why should you care?

Click-ops drifts; IaC reviews and repeats.

See it live — copy this example

Use an Azure lab/free subscription. Prefer Azure CLI or Portal. Delete idle App Service plans, SQL DBs, and AKS clusters when practice is done.

# ARM Templates Overview
# bicep / terraform / arm — declare resources, then deploy
echo "IaC module notes: ARM Templates Overview"

What happened?

Prefer parameterized modules and separate dev/test/prod parameter files.
Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

Run the CLI/portal steps in a lab subscription.
Write the resource names you used.
Note estimated monthly cost for the SKU.
Repeat in a second region (conceptually).
Add the resource to a simple architecture diagram.

Remember

You can explain ARM Templates Overview simply. You practiced one Azure action. You know a cost or security risk.

What are pipeline templates and how are they used? Answer: Templates let you reuse pipeline steps across projects — great for standardization. Example: You can create a reusable file: 📄 .azure-pipelines/build-template.yml steps: - script: dotnet restore - script: dotnet build Then in your main pipeline: extends: template: .azure-pipelines/build-template.yml This keeps your YAML DRY (Don’t Repeat Yourself) and consistent.

Use versioned artifacts — keep your last working package and redeploy it. Example: If your new API build breaks production, you can quickly redeploy the previous successful release version from Azure DevOps → Releases → “Redeploy”. 8⃣ How do you deploy infrastructure using ARM templates or Bicep in Azure DevOps?

You can deploy Infrastructure as Code (IaC) directly from your pipeline using ARM or Bicep files. Follow: Example (YAML): task: AzureResourceManagerTemplateDeployment@3 inputs: deploymentScope: 'Resource Group' azureReso…

Assign proper RBAC roles (e.g., Contributor or Owner). Usage in pipeline: - task: AzureResourceManagerTemplateDeployment@3 inputs: azureResourceManagerConnection: 'MyServiceConnection' resourceGroupName: 'MyRG' location: 'East US' csmFile: 'infra/main.json' Example scenario: Your IaC pipeline uses the “ProdServiceConnection” to deploy Bicep templates to the production resource group, without developers ever seeing credentials. 4⃣ How can you automate environment creation and teardown?

You can automate creating and destroying environments (like dev, test, or staging) using pipeline logic and IaC tools. ✅ Example (Bicep – Create Environment): task: AzureCLI@2 inputs: azureSubscription: 'MyServiceConnect…
