Mastering Azure Automation: Deploying and Managing Infrastructure with Bicep and Azure Functions

Section 1: Setting the Foundation with Bicep for Modular Infrastructure as Code

In the world of modern cloud computing, managing infrastructure effectively is crucial to maintaining scalability, cost efficiency, and reliability. Microsoft Azure provides Bicep—a domain-specific language (DSL) for Infrastructure as Code (IaC)—as a powerful tool for defining and deploying Azure resources with precision. In this section, we’ll explore how to structure and set up a modular Bicep-based project, emphasizing the benefits of modularity and reusability in cloud resource management.

Why Bicep for IaC?

Bicep is an abstraction over Azure Resource Manager (ARM) templates, designed to make IaC simpler and more readable. It eliminates the verbosity of JSON-based ARM templates while retaining their power and flexibility. With Bicep, you can:

• Simplify Syntax: Write clean, readable templates with less boilerplate.
• Ensure Consistency: Use parameterization to standardize deployments across environments.
• Promote Modularity: Break large templates into smaller, reusable components for better maintainability.

info: Bicep simplifies Azure resource management by reducing complexity, improving readability, and enabling modular deployments. It is an essential tool for anyone looking to embrace modern Infrastructure as Code practices.

Project Overview

In this project, we’ll build a modular Bicep-based system to deploy an Azure environment consisting of:

• Virtual Network (VNet): Provides networking for other resources.
• Storage Account: Stores data and files securely in Azure.
• Virtual Machine (VM): Hosts applications or workloads.

We’ll adopt a modular approach, where each resource is defined in its own Bicep file, making it easier to reuse and manage components.

---

Designing a Modular Structure

A modular structure is critical when working with IaC, especially for projects that are expected to scale. Here’s how we structure the project:

AzureBicepProject/
├── main.bicep         # Main orchestration file
├── vnet.bicep         # Module for Virtual Network
├── storage.bicep      # Module for Storage Account
├── vm.bicep           # Module for Virtual Machine
├── parameters.json    # Optional: Parameter values for deployment
└── scripts/
    ├── deploy.bat     # Deployment script
    ├── validate.bat   # Validation script
    └── cleanup.bat    # Cleanup script

info: A modular approach enhances code reuse, simplifies debugging, and allows team members to work on separate modules independently, increasing development efficiency.

---

Step 1: The Main Orchestration File

The main.bicep file acts as the entry point for our project. It orchestrates the deployment by referencing each modular file as a module. This approach allows us to manage dependencies between resources easily.

main.bicep

@description('Location for all resources')
param location string = resourceGroup().location

@description('Administrator Username for VM')
param adminUsername string

@description('Administrator Password for VM')
@secure()
param adminPassword string

module vnet 'vnet.bicep' = {
  name: 'vnetModule'
  params: {
    location: location
  }
}

module storage 'storage.bicep' = {
  name: 'storageModule'
  params: {
    location: location
  }
}

module vm 'vm.bicep' = {
  name: 'vmModule'
  params: {
    location: location
    adminUsername: adminUsername
    adminPassword: adminPassword
    subnetId: vnet.outputs.subnetId
  }
}

output vnetId string = vnet.outputs.vnetId
output storageAccountId string = storage.outputs.storageAccountId
output vmId string = vm.outputs.vmId

info: The main.bicep file handles dependency management automatically by referencing module outputs, ensuring resources are deployed in the correct order.

Key Highlights:

• Parameterization: The location, adminUsername, and adminPassword parameters make the file reusable across different environments.
• Module References: Each resource type is defined in a separate file (vnet.bicep, storage.bicep, and vm.bicep), referenced as modules.
• Outputs: The vnetId, storageAccountId, and vmId outputs provide IDs for downstream workflows or logging.

info: Outputs from main.bicep provide critical information, such as resource IDs, that can be logged, passed to other scripts, or used in downstream workflows.

---

Step 2: Modular Resource Definitions

Each resource is defined in its own file, keeping the project clean and modular. Let’s take a look at an example module:

Virtual Network Module (vnet.bicep)

@description('Location for the Virtual Network')
param location string

@description('Virtual Network Address Space')
param vnetAddressPrefix string = '10.0.0.0/16'

@description('Subnet Address Prefix')
param subnetAddressPrefix string = '10.0.0.0/24'

resource vnet 'Microsoft.Network/virtualNetworks@2022-05-01' = {
  name: 'myVNet'
  location: location
  properties: {
    addressSpace: {
      addressPrefixes: [
        vnetAddressPrefix
      ]
    }
    subnets: [
      {
        name: 'default'
        properties: {
          addressPrefix: subnetAddressPrefix
        }
      }
    ]
  }
}

output vnetId string = vnet.id
output subnetId string = vnet.properties.subnets[0].id

Why Modularize?

• Reusability: The vnet.bicep module can be reused in other projects or environments with different configurations.
• Ease of Maintenance: Changes to the Virtual Network logic only require edits in this module.

tip: The vnet.bicep module is reusable in other Azure projects by simply adjusting parameters like vnetAddressPrefix and subnetAddressPrefix.

---

Step 3: Automating Deployment

• Deployment is automated using a script (deploy.bat), which simplifies the execution process for the team or CI/CD pipelines.

scripts/deploy.bat

@echo off

set RESOURCE_GROUP=<YourResourceGroupName>
set DEPLOYMENT_NAME=MyDeployment
set ADMIN_USERNAME=<YourAdminUsername>
set ADMIN_PASSWORD=<YourAdminPassword>

az deployment group create ^
  --name %DEPLOYMENT_NAME% ^
  --resource-group %RESOURCE_GROUP% ^
  --template-file ../main.bicep ^
  --parameters adminUsername=%ADMIN_USERNAME% adminPassword=%ADMIN_PASSWORD%

Execution: Run the script in the terminal:

scripts\deploy.bat

info: Deployment scripts like deploy.bat streamline resource provisioning, making it accessible to both developers and CI/CD pipelines.

---

Benefits of Modularity

1. Scalability: Adding new resources (e.g., a database) requires creating a new module without altering the main file significantly.
2. Collaboration: Teams can work on individual modules without conflicts.
3. Testing: Individual modules can be validated separately, reducing errors during deployment.

---

tip: Always validate your Bicep templates using tools like az bicep build to catch syntax errors and ensure deployments succeed on the first attempt.

Next Steps

With the foundation laid, we’ll explore how to validate, deploy, and automate resource management in the next sections. Stay tuned as we dive into Azure Functions for automation and advanced deployment techniques.

---

Section 2

Step 1: Validating Bicep Templates

Validation ensures your Bicep templates are syntactically correct and compatible with Azure. Using the az bicep build command, you can compile your templates into ARM JSON format without deploying them. This is a quick way to identify errors before committing to a deployment.

Validation Script: validate.bat

Here’s the script to validate your templates:

@echo off

:: Define the main Bicep file
set TEMPLATE_FILE=../main.bicep

echo Validating Bicep template: %TEMPLATE_FILE%

:: Run Bicep build to validate the file
az bicep build --file %TEMPLATE_FILE%

if %ERRORLEVEL%==0 (
    echo Validation successful!
) else (
    echo Validation failed. Please check your Bicep template for errors.
    exit /b 1
)

info: Validation scripts like validate.bat save time by catching syntax errors early in the development process, preventing deployment failures.

---

Running the Validation Script

To validate your Bicep templates:

1. Open a command prompt or terminal.
2. Navigate to the scripts/ folder in your project.
3. Run the script:

scripts\validate.bat

Output:

• If the templates are valid, the script will display Validation successful!.
• Otherwise, it will provide details about the error(s), helping you quickly identify and fix issues.

tip: Always validate your Bicep templates after making changes to ensure consistency and accuracy.

---

Step 2: Deploying Bicep Templates

Once validated, you can deploy your infrastructure using the az deployment group create command. For ease of use, we’ve encapsulated this process in a deployment script.

Deployment Script: deploy.bat

@echo off

:: Define deployment parameters
set RESOURCE_GROUP=<YourResourceGroupName>
set DEPLOYMENT_NAME=MyDeployment
set ADMIN_USERNAME=<YourAdminUsername>
set ADMIN_PASSWORD=<YourAdminPassword>

echo Deploying resources to Azure...

:: Deploy the Bicep template
az deployment group create ^
  --name %DEPLOYMENT_NAME% ^
  --resource-group %RESOURCE_GROUP% ^
  --template-file ../main.bicep ^
  --parameters adminUsername=%ADMIN_USERNAME% adminPassword=%ADMIN_PASSWORD%

if %ERRORLEVEL%==0 (
    echo Deployment successful!
) else (
    echo Deployment failed. Please check the logs for more details.
    exit /b 1
)

info: Automating deployments with scripts ensures consistency across environments and reduces the risk of manual errors.

---

Running the Deployment Script

To deploy your templates:

1. Ensure the validate.bat script has confirmed your templates are error-free.
2. Open a command prompt or terminal.
3. Navigate to the scripts/ folder.
4. Run the deployment script:

scripts\deploy.bat

Output:

• If successful, the resources will be deployed to your specified Azure resource group.

tip: Keep sensitive information, such as administrator credentials, secure by storing them in environment variables or Azure Key Vault instead of hardcoding them in scripts.

---

Step 3: Verifying the Deployment

After the deployment is complete, it’s essential to verify that all resources are correctly provisioned and configured.

Verification Checklist

Azure Portal:

• Log in to the Azure Portal and navigate to the resource group you deployed to.
  • Check that the Virtual Network, Storage Account, and Virtual Machine are present.
• Azure CLI:
  • Use the CLI to list deployed resources:

az resource list --resource-group <YourResourceGroupName>

• • Confirm that each resource has the expected properties and status.

info: Verification ensures that your resources are deployed correctly and aligned with your project’s requirements.

---

Troubleshooting Common Deployment Issues

If your deployment fails:

1. Review the Error Logs:
   • The deploy.bat script provides logs detailing any errors. Check these logs for specific messages.
2. Validate Again:
   • Run the validate.bat script to ensure no changes caused errors in the template.
3. Check Azure Quotas:
   • Ensure your subscription has enough quota to deploy the requested resources.

az vm list-usage --location <YourLocation>

tip: Common issues include invalid parameters, insufficient permissions, or exceeding Azure quotas. Address these before retrying the deployment.

---

Conclusion

By validating your Bicep templates and automating the deployment process, you can confidently provision Azure resources while minimizing errors. In the next section, we’ll explore how to enhance this workflow by automating resource management and optimization with Azure Functions.

---

Section 3: Automating Infrastructure Management with Azure Functions

Automation is a cornerstone of modern DevOps practices, enabling scalability, efficiency, and reduced manual intervention. In this section, we’ll explore how to leverage Azure Functions to automate resource management tasks such as scaling, cost optimization, and tagging.

What Are Azure Functions?

Azure Functions is a serverless compute service that allows you to run event-driven code without managing infrastructure. These lightweight functions can respond to various triggers, such as HTTP requests, timers, or Azure resource events, making them ideal for automating cloud operations.

---

Use Case: Automating Resource Tagging

To demonstrate the power of Azure Functions, we’ll create a function that automatically tags Azure resources with metadata (e.g., Owner, Environment) whenever they are created. Proper tagging helps with resource organization, cost tracking, and compliance.

---

Step 1: Setting Up an Azure Function App

1. Create the Function App
2. Use the Azure CLI to create a Function App:

az functionapp create \
  --resource-group <YourResourceGroupName> \
  --consumption-plan-location <YourLocation> \
  --name <YourFunctionAppName> \
  --storage-account <YourStorageAccountName> \
  --runtime python

1. Ensure the storage account () already exists, as it’s required for the Function App.

2. Install the Azure Functions Core Tools

   • Install the Azure Functions Core Tools for local development:
   • Installation guide

---

Step 2: Writing the Azure Function

We’ll use a Python-based Azure Function triggered by an HTTP request. The function will read metadata from the request payload and apply tags to a specified resource.

Function Code: auto_tag.py

import logging
import os
from azure.identity import DefaultAzureCredential
from azure.mgmt.resource import ResourceManagementClient
from azure.functions import HttpRequest, HttpResponse

def main(req: HttpRequest) -> HttpResponse:
    logging.info('Processing resource tagging request.')

    # Parse request payload
    try:
        req_body = req.get_json()
        resource_id = req_body.get('resource_id')
        tags = req_body.get('tags', {})
    except ValueError:
        return HttpResponse("Invalid request payload", status_code=400)

    # Authenticate with Azure
    credential = DefaultAzureCredential()
    client = ResourceManagementClient(credential, os.getenv('AZURE_SUBSCRIPTION_ID'))

    # Apply tags to the resource
    try:
        resource = client.resources.get_by_id(resource_id, api_version="2021-04-01")
        resource.tags.update(tags)
        client.resources.begin_create_or_update_by_id(resource.id, "2021-04-01", resource)
        return HttpResponse(f"Tags applied to resource: {resource_id}", status_code=200)
    except Exception as e:
        logging.error(f"Error tagging resource: {str(e)}")
        return HttpResponse(f"Error tagging resource: {str(e)}", status_code=500)

tip: This function uses the Azure SDK to authenticate and interact with resources. Ensure the Function App has the necessary permissions to modify resources in your subscription.

---

Step 3: Deploying the Function

1. Publish the Function to Azure Use the Azure CLI to deploy the function:

func azure functionapp publish <YourFunctionAppName>

1. Test the Function
   • Send a POST request to the function endpoint:

curl -X POST <FunctionAppURL>/api/auto_tag \
     -H "Content-Type: application/json" \
     -d '{
          "resource_id": "/subscriptions/<YourSubscriptionID>/resourceGroups/<YourResourceGroupName>/providers/Microsoft.Compute/virtualMachines/<YourVMName>",
          "tags": {
            "Environment": "Development",
            "Owner": "Admin"
          }
        }'

tip: Replace with your function's URL, available in the Azure Portal after deployment.

---

Step 4: Automating Trigger Events

While the above example uses an HTTP trigger, you can automate tagging further by using an Event Grid trigger. This setup listens for Microsoft.Resources.ResourceWriteSuccess events and applies tags automatically.

Steps to Configure an Event Grid Trigger

1. Create an Event Grid Subscription:

az eventgrid event-subscription create \
  --resource-id "/subscriptions/<YourSubscriptionID>/resourceGroups/<YourResourceGroupName>" \
  --name AutoTagSubscription \
  --endpoint <FunctionAppURL>/api/auto_tag

1. Update the Function to Handle Event Data: Modify the function to parse Event Grid payloads and extract resource_id:

def main(event: HttpRequest) -> HttpResponse:
    try:
        event_data = event.get_json()
        resource_id = event_data.get('data', {}).get('resourceId')
        tags = {"Environment": "Development", "Owner": "Admin"}
        # Rest of the tagging logic...
    except ValueError:
        return HttpResponse("Invalid event payload", status_code=400)

info: Event Grid triggers allow you to automate resource management tasks in real-time, eliminating the need for manual intervention.

---

Step 5: Monitoring and Logging

Use Azure Monitor to track function executions and log any errors or performance metrics:

Enable Application Insights during Function App creation for detailed monitoring. Review logs in the Azure Portal under the “Monitor” tab for your Function App.

tip: Logging and monitoring help identify issues quickly and improve the reliability of your automation workflows.

---

Conclusion

With Azure Functions, you can automate repetitive tasks, such as tagging resources, scaling VMs, or cleaning up unused resources. The flexibility of triggers—HTTP, timers, or events—makes Azure Functions a powerful addition to any DevOps toolkit. In the next section, we’ll expand this automation with Infrastructure as Code, combining Azure Functions with Bicep templates.

---

Section 4: Integrating Automation with Infrastructure as Code

In the previous sections, we deployed resources using Bicep templates and introduced Azure Functions for automation. In this section, we’ll bring these two elements together, showcasing how to integrate Azure Functions into your Bicep workflows. This approach ensures your infrastructure not only deploys seamlessly but also includes built-in automation for real-time management.

---

Use Case: Automated Cleanup of Unused Resources

Cloud environments often accumulate unused resources, leading to increased costs. Let’s create an automated cleanup solution that identifies and deletes unattached disks using Azure Functions. We’ll integrate this function directly into our Bicep deployment.

---

Step 1: Adding Azure Functions to Your Bicep Templates

We’ll extend the main.bicep file to include the deployment of an Azure Function App, ensuring the function is deployed and configured along with the other resources.

Update main.bicep

module functionApp 'function-app.bicep' = {
  name: 'functionAppModule'
  params: {
    location: location
    functionAppName: 'resourceCleanupFunction'
    storageAccountName: storageAccount.name
  }
}

output functionAppUrl string = functionApp.outputs.functionAppUrl

Create function-app.bicep

@description('Location of the Function App')
param location string

@description('Name of the Function App')
param functionAppName string

@description('Name of the Storage Account')
param storageAccountName string

resource storageAccount 'Microsoft.Storage/storageAccounts@2022-09-01' existing = {
  name: storageAccountName
}

resource appServicePlan 'Microsoft.Web/serverfarms@2022-03-01' = {
  name: '${functionAppName}-plan'
  location: location
  sku: {
    name: 'Y1'
    tier: 'Dynamic'
  }
  kind: 'functionapp'
}

resource functionApp 'Microsoft.Web/sites@2022-03-01' = {
  name: functionAppName
  location: location
  kind: 'functionapp'
  properties: {
    serverFarmId: appServicePlan.id
    siteConfig: {
      appSettings: [
        {
          name: 'AzureWebJobsStorage'
          value: storageAccount.properties.primaryEndpoints.blob
        }
        {
          name: 'WEBSITE_RUN_FROM_PACKAGE'
          value: '1'
        }
      ]
    }
  }
}

output functionAppUrl string = 'https://${functionApp.name}.azurewebsites.net'

---

Step 2: Writing the Cleanup Function

The Azure Function identifies unattached disks and deletes them, saving costs.

cleanup_disks.py

import logging
import os
from azure.identity import DefaultAzureCredential
from azure.mgmt.compute import ComputeManagementClient

def main(mytimer: func.TimerRequest) -> None:
    logging.info("Starting cleanup of unattached disks...")

    credential = DefaultAzureCredential()
    subscription_id = os.getenv('AZURE_SUBSCRIPTION_ID')
    compute_client = ComputeManagementClient(credential, subscription_id)

    for disk in compute_client.disks.list():
        if disk.managed_by is None:
            logging.info(f"Deleting unattached disk: {disk.name}")
            compute_client.disks.begin_delete(disk.resource_group, disk.name)

---

Step 3: Deploying the Updated Infrastructure

Deploy your updated main.bicep file, which now includes the Function App:

scripts\deploy.bat

---

Step 4: Automating Function Execution

To automate the execution of the cleanup function, we’ll set up a timer trigger.

Add Timer Trigger in function.json

{
  "bindings": [
    {
      "name": "mytimer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 0 1 * * *"
    }
  ]
}

info: The schedule property follows the CRON format. In this case, the function runs at 1:00 AM UTC daily.

---

Step 5: Monitoring and Validating

Monitor Execution

• View logs in the Azure Portal under Monitor > Logs for your Function App.
• Verify that unattached disks are deleted successfully.

Test the Function You can manually trigger the function to test its logic:

curl -X POST <FunctionAppUrl>/api/cleanup_disks

---

Benefits of Integration

By integrating Azure Functions with Bicep templates, you achieve:

1. Seamless Deployment: The function is deployed and configured alongside your infrastructure.
2. Automated Management: Functions provide continuous, real-time management of resources.
3. Cost Optimization: Automating tasks like cleaning up unused resources reduces unnecessary cloud costs.

tip: This integration ensures your infrastructure is self-sustaining and optimized from the moment it is deployed.

---
