When designing Microsoft Azure Infrastructure Solutions, especially when preparing to take the AZ-305 exam, one key area of focus should be on the automation of application deployment. Automating the application deployment process can reduce the risk of human error, streamline the workflow, and dramatically speed up the overall deployment process, all of which contributes to increased productivity and reduced costs.
Automation Tools in Azure
There are several methodologies and tools available in the Azure environment that can help you automate application deployment. These include Azure Resource Manager Templates (ARM templates), Azure DevOps, and Azure PowerShell.
Azure Resource Manager Templates
Azure Resource Manager Templates (ARM templates) are one of the most commonly adopted tools for automating resource deployment within Azure. ARM templates are JSON files that define the resources needed for your application. You can deploy these resources in a reliable and consistent manner, which ensures the compliance and standards of the necessary infrastructure across multiple environments such as Dev, QA, and Production.
Here is an example of using ARM template for deploying a Web App:
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {},
"resources": [
{
"type": "Microsoft.Web/sites",
"apiVersion": "2016-03-01",
"name": "myWebApp",
"location": "West Europe",
"properties": {
"serverFarmId": "/subscriptions/0b1f6471-1bf0-4dda-aec3-111122223333/resourceGroups/myResourceGroup/providers/Microsoft.Web/serverfarms/myAppServicePlan"
}
}
]
}
Azure DevOps
Azure DevOps is another popular tool for implementing automation in application deployment. Through integrated pipelines, you can build, test, and deploy your applications seamlessly, catering to both CI (Continuous Integration) and CD (Continuous Deployment) practices.
In contrast to ARM Templates, Azure DevOps provides a more intuitive graphical user interface and is less hard-coding-intensive, making it easier to adopt for teams less proficient in coding.
Below is an illustration of a Pipeline in Azure DevOps:
- Choose the Source Code Repository
- Define the Build Pipeline,
- Define the Release Pipeline.
Azure PowerShell
Azure PowerShell is a set of cmdlets that help you manage and deploy Azure resources directly from the PowerShell command line. Azure PowerShell is an excellent match for deployment scripting and automation on Windows platforms.
Below is an example of using Azure PowerShell for deploying a Web App:
# Login to Azure
Login-AzAccount
# Select subscription
Set-AzContext -SubscriptionId 'YourSubscriptionId'
# Create a resource group
New-AzResourceGroup -Name 'ResourceGroupName' -Location 'West Europe'
# Create an App Service plan
New-AzAppServicePlan -ResourceGroupName 'ResourceGroupName' -Name 'AppServicePlan' -Location 'West Europe' -Tier Free
# Create a web app
New-AzWebApp -ResourceGroupName 'ResourceGroupName' -Name 'WebAppName' -Location 'West Europe' -AppServicePlan 'AppServicePlan'
To Summarize
To summarize, automating application deployment in Microsoft Azure offers numerous benefits. While Azure Resource Manager Templates, Azure DevOps, and Azure PowerShell, all have their distinct advantages, your choice of tool should be based on your project requirements and on the skills and comfort level of your development team.
