Azure Developer Challenges and Proven Solutions
Below are five of the best challenges that Azure developers face and successful solutions to overcome them.
Navigating a Vast and Evolving Service Ecosystem
Challenge: The very large number of Azure services (more than 200) and their fast pace of evolution make it challenging for developers. It’s unclear which service is most suitable for a particular scenario, and documentation may fall behind the introduction of new features.
Solution:
- Master the core developer services first and then use the Azure Well-Architected Framework to learn about best practices.
- Take advantage of Azure’s deep learning paths on Microsoft Learn, which are designed to help you develop skills for a particular role and technology.
Real-Time Example: You’re a new developer and you need to create a web API. Rather than being overwhelmed with an ocean of possibilities, you concentrate on a handful of core services:
- Azure App Service: To host the web API.
- Azure Functions: To build serverless, event-driven elements.
- Azure Cosmos DB or Azure SQL Database: For storing data.
Code Example for the solution:
// C# code to connect to a core service like Azure Key Vault.
// This highlights a developer using a specific service, not getting overwhelmed by the entire ecosystem.
using Azure.Identity;
using Azure.Security.KeyVault.Secrets;
// The SecretClient can authenticate with Azure AD using DefaultAzureCredential
// This is a common and recommended practice.
var client = new SecretClient(new Uri(“https://my-vault-name.vault.azure.net/”), new DefaultAzureCredential());
KeyVaultSecret secret = await client.GetSecretAsync(“MySecretKey”);
Console.WriteLine($”The secret is: {secret.Value}”);

Managing Complex Identity and Access Management (IAM)
Challenge: Misconfigured IAM roles and permissions can cause security issues or prevent developers from accessing resources they require. The distinction between Azure AD users, groups, service principals, and managed identities is often a source of confusion.
Solution:
- Take on the least privilege principle.
- Leverage Azure Active Directory (Azure AD) and Managed Identities to manage authentication and authorization.
- Implement role-based access control (RBAC) to grant permissions at the appropriate scope (subscription, resource group, or single resource).
Real-Time Example: A coder must deploy an application to Azure App Service that will link to an Azure SQL Database. Rather than providing the coder with a username and password, you create a managed identity for the App Service.
That identity is then assigned a particular role (e.g., “SQL DB Contributor”) to the database. This method eliminates the storage of credentials in code or configuration files, greatly improving security.
Code Example for Solution:
// ARM template snippet to assign a managed identity to a web app.
// This declarative code demonstrates a secure, programmatic solution.
{
“type”: “Microsoft.Web/sites”,
“name”: “[parameters(‘webAppName’)]”,
“apiVersion”: “2022-03-01”,
“location”: “[resourceGroup().location]”,
“identity”: {
“type”: “SystemAssigned”
},
“properties”: {
// … other properties
}
},
{
“type”: “Microsoft.Authorization/roleAssignments”,
“apiVersion”: “2022-04-01-preview”,
“name”: “[guid(resourceId(‘Microsoft.Web/sites’, parameters(‘webAppName’)), ‘role-assignment-for-db’)]”,
“dependsOn”: [
“[resourceId(‘Microsoft.Web/sites’, parameters(‘webAppName’))]”,
“[resourceId(‘Microsoft.Sql/servers/databases’, parameters(‘sqlServerName’), parameters(‘sqlDatabaseName’))]”
],
“properties”: {
“roleDefinitionId”: “[concat(subscription().id, ‘/providers/Microsoft.Authorization/roleDefinitions/’, ’82a20120-d25d-4fdd-aa7c-17e997b6a132′)]”,
“principalId”: “[reference(resourceId(‘Microsoft.Web/sites’, parameters(‘webAppName’)), ‘2022-03-01’).identity.principalId]”,
“scope”: “[resourceId(‘Microsoft.Sql/servers/databases’, parameters(‘sqlServerName’), parameters(‘sqlDatabaseName’))]”
}
}

Overlooking Cost Optimization and Management
Challenge: Developers can unintentionally spin up costly resources or run services unnecessarily, causing unplanned and sometimes substantial expenses. Insufficient knowledge of pricing tiers and billing can lead to cost overruns.
Solution:
- Embed FinOps (Financial Operations) practices in the development cycle.
- To allocate budgets, manage spending, and receive advice, use Azure Advisor and Azure Cost Management.
- Use the Azure Pricing Calculator to estimate costs in advance of provisioning resources.
Real-Time Scenario: A developer is experimenting with an application deployed on a high-end, costly Azure Virtual Machine (VM). Lacking a cost-saving strategy, they may keep the VM activated overnight, running up avoidable expenses.
An easy fix is to apply an Azure Policy or a Scheduled Shutdown rule on the VM to automatically de-allocate the same during off-work hours, avoiding substantial amounts of money.
Code Example:
# PowerShell script to create a scheduled shutdown for a VM.
# This automates cost savings by turning off development VMs.
$resourceGroupName = “MyDevResourceGroup”
$vmName = “MyExpensiveDevVM”
# Create an automation account for the scheduled shutdown
New-AzAutomationAccount -Name “ShutdownAutomation” -ResourceGroupName $resourceGroupName -Location “WestUS”
# Create a schedule that triggers at 7 PM PST every weekday
$schedule = New-AzAutomationSchedule -AutomationAccountName “ShutdownAutomation” -Name “DailyShutdown” -StartTime “19:00” -TimeZone “Pacific Standard Time” -Frequency “Daily” -WeekDays “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”
# Create the shutdown runbook
New-AzAutomationRunbook -AutomationAccountName “ShutdownAutomation” -Name “ShutdownVM” -Location “WestUS” -Type “PowerShell”
# … add runbook content to safely shut down the VM …
# Link the runbook to the schedule
Register-AzAutomationScheduledRunbook -AutomationAccountName “ShutdownAutomation” -RunbookName “ShutdownVM” -ScheduleName $schedule.Name
Challenges with CI/CD and Automation
Challenge: Implementing a solid Continuous Integration/Continuous Deployment (CI/CD) pipeline in Azure DevOps or GitHub Actions is complicated. Build agent, variable, and pipeline permission problems frequently result in failed builds and deployments.
Solution:
- Begin with a simple, well-documented pipeline and build from there. For version control and consistency, use YAML files and pipeline templates as the source of truth.
- Utilize environment variables and Azure Key Vault to store secrets so that credentials are not hard-coded.
Real-Time Example: A team is having issues performing manual deployments of their web application, which is painstakingly slow and prone to errors. They implement Azure Pipelines in order to automate their process.
- CI: A build pipeline is invoked on each code commit into GitHub. It does out unit testing and builds the code.
- CD: After the build is successful, a release pipeline deploys the code automatically to a staging environment, and with an extra manual approval step, to production. This is an automated process, eliminating the risk of human error and the time taken for deployment.
Code Example (YAML Azure Pipelines):
# A simple CI/CD YAML pipeline for a .NET Core app
trigger:
– main
pool:
vmImage: ‘ubuntu-latest’
variables:
buildConfiguration: ‘Release’
stages:
– stage: Build
displayName: ‘Build project’
jobs:
– job: BuildJob
steps:
– script: dotnet build –configuration $(buildConfiguration)
displayName: ‘dotnet build’
– task: DotNetCoreCLI@2
displayName: ‘dotnet publish’
inputs:
command: ‘publish’
publishWebProjects: true
arguments: ‘–configuration $(buildConfiguration) –output $(Build.ArtifactStagingDirectory)’
zipAfterPublish: true
– task: PublishBuildArtifacts@1
displayName: ‘Publish Artifacts’
inputs:
pathtoPublish: ‘$(Build.ArtifactStagingDirectory)’
artifactName: ‘drop’
– stage: Deploy
displayName: ‘Deploy to Azure App Service’
jobs:
– job: DeployJob
steps:
– task: AzureWebApp@1
displayName: ‘Deploy Azure App Service’
inputs:
azureSubscription: ‘Azure-Subscription-Name’
appType: ‘webAppLinux’
appName: ‘MyWebApp-Prod’
package: ‘$(Pipeline.Workspace)/drop/*.zip’

Securing Applications and Infrastructure
Challenge: When it comes to development, functionality and speed are usually more important than security. This translates to hard-coded secrets, network rule misconfigurations, and poor data protection as possible vulnerabilities in the cloud.
Solution:
- Adopt a “shift-left” security approach, incorporating security habits right from the beginning of the development cycle.
- Azure Key Vault is a safe way to store secrets, certificates, and API keys.
- Make use of Azure’s built-in security capabilities and implement network security best practices.
Real-Time Example: A developer is creating a web application that must call an external API. Rather than hard-coding the API key into the app’s configuration file, they encrypt it in an Azure Key Vault.
The Azure App Service that hosts the app is then authorized to read this secret from the vault via a managed identity. This keeps the secret hidden in source code and enables effortless rotation without redeployment of the application.
Code Example:
# Python code to retrieve a secret from Azure Key Vault
# This shows how a secure connection is made using a managed identity.
import os
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
# The URL of your Key Vault
key_vault_url = os.environ[“KEY_VAULT_URL”]
# Use DefaultAzureCredential to authenticate
# This automatically finds credentials from the environment (e.g., Managed Identity)
credential = DefaultAzureCredential()
secret_client = SecretClient(vault_url=key_vault_url, credential=credential)
# Retrieve the secret
try:
api_key_secret = secret_client.get_secret(“External-API-Key”)
api_key = api_key_secret.value
print(“Successfully retrieved API key from Key Vault.”)
except Exception as ex:
print(f”Error retrieving secret: {ex}”)
api_key = None
Troubleshooting and Monitoring
Challenge: In the event that an Azure application fails, it is hard to identify the underlying cause. Errors are elusive, and developers might not have an idea of which tools are required in order to obtain the necessary logs and metrics.
Solution:
- Actively deploy monitoring and logging right up front.
- Leverage Azure Monitor and Application Insights to gather metrics, logs, and traces.
- Configure alerts for issues of major errors and performance.
Real-Time Example: There is an API endpoint that occasionally returns a 500 error, but not every time. Rather than attempt to recreate the error manually, the developer takes advantage of Application Insights to:
- See a live stream of all the requests and their status codes.
- Look at the logs for the particular failed request to view the complete stack trace and error message.
- Create an alert to notify the team through email or a Teams channel whenever a 500 error count is above a threshold.
Code Example: (JSON)
/*
Conceptual JSON from an Azure Monitor Log Analytics query.
This demonstrates how a developer can query logs to find errors.
*/
{
“query”: “
traces
| where customDimensions.prop__{‘request/name’} contains ‘api/myfunction’
| where severityLevel == ‘Error’
| project timestamp, customDimensions.prop___{‘request/id’}, customDimensions.prop___{‘request/name’}, message, exception
| order by timestamp desc
“,
“results”: [
{
“timestamp”: “2023-10-26T14:30:15Z”,
“request_id”: “abc-123”,
“request_name”: “api/myfunction”,
“message”: “Function execution failed.”,
“exception”: “System.NullReferenceException: Object reference not set to an instance of an object.”
}
]
}
