To create an Azure App Service Web App, you have several options:
**Azure Portal Method:**
1. Navigate to the Azure Portal and select 'Create a resource'
2. Search for 'Web App' and click Create
3. Configure the basics: subscription, resource group, web app name, runtime stack, operating system, and region
4. Select an App Service Plan which determines the compute resources and pricing tier
5. Review and create the resource
**Azure CLI Method:**
Use the command: az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name myWebApp --runtime "DOTNET|6.0"
**Key Configuration Elements:**
- **App Service Plan:** Defines the compute resources (CPU, memory) and features available. Tiers range from Free to Premium.
- **Runtime Stack:** The programming language and version your application uses
- **Operating System:** Choose between Windows or Linux based on your requirements
- **Region:** Geographic location affecting latency and compliance
**Important Features:**
- Built-in auto-scaling and load balancing
- Continuous deployment integration with GitHub, Azure DevOps, and other repositories
- Custom domain and SSL certificate support
- Deployment slots for staging environments
- Application Insights integration for monitoring
**Deployment Options:**
- FTP/FTPS upload
- Git-based deployment
- ZIP deploy
- Docker container deployment
- Azure DevOps pipelines
After creation, you can access your web app via the default URL format: https://[webappname].azurewebsites.net. Configuration settings, connection strings, and application settings can be managed through the portal or programmatically through the Azure SDK.
Create an Azure App Service Web App - Complete Guide
Why is This Important?
Azure App Service Web Apps are a fundamental component of the AZ-204 exam, representing one of the most commonly used Platform-as-a-Service (PaaS) offerings in Azure. Understanding how to create and configure web apps is essential for any Azure developer, as it forms the foundation for deploying web applications, REST APIs, and mobile backends in the cloud.
What is Azure App Service Web App?
Azure App Service is a fully managed platform for building, deploying, and scaling web applications. A Web App is a specific resource type within App Service that hosts web applications written in various languages including .NET, Java, Node.js, Python, PHP, and Ruby. Key characteristics include:
• Managed Infrastructure - Microsoft handles OS patching, security updates, and scaling • Multiple Language Support - Supports various programming languages and frameworks • Built-in CI/CD - Integration with Azure DevOps, GitHub, and other repositories • Custom Domains and SSL - Easy configuration of custom domains with SSL certificates • Auto-scaling - Automatic scaling based on metrics or schedules
How It Works
Creating a Web App involves several key components:
1. App Service Plan: Defines the compute resources (CPU, memory, features) allocated to your app. Plans include Free, Shared, Basic, Standard, Premium, and Isolated tiers.
2. Resource Group: A logical container that holds related Azure resources.
3. Runtime Stack: The programming language and version your application uses.
4. Region: The geographic location where your app is hosted.
Methods to Create a Web App:
• Azure Portal - GUI-based creation through the web interface • Azure CLI - Using commands like az webapp create • Azure PowerShell - Using cmdlets like New-AzWebApp • ARM Templates - Infrastructure as Code using JSON templates • Bicep - Domain-specific language for ARM template deployment
Key Configuration Settings:
• Application Settings - Environment variables for your app • Connection Strings - Database and service connection information • Default Documents - Specify which files to serve as the homepage • Path Mappings - Virtual directories and applications • Always On - Keeps the app loaded even with no traffic (Standard tier and above)
Exam Tips: Answering Questions on Create an Azure App Service Web App
Tip 1: Know the App Service Plan Tiers Understand the differences between tiers. Free and Shared tiers share resources and have limitations. Basic, Standard, and Premium offer dedicated resources. Isolated tier provides network isolation.
Tip 2: Remember Deployment Slots Deployment slots are available in Standard tier and above. They allow staging deployments and slot swapping for zero-downtime deployments.
Tip 3: Understand Scaling Options Manual scaling is available in Basic and above. Auto-scaling based on metrics or schedules requires Standard tier or higher.
Tip 4: Know CLI Commands Be familiar with Azure CLI commands: • az webapp create - Creates a web app • az webapp config - Configures app settings • az webapp deployment - Manages deployments
Tip 5: Application Settings vs Connection Strings Application settings are environment variables. Connection strings are specifically for database connections and are typed (SQL Database, MySQL, etc.).
Tip 6: Always On Feature Questions may test knowledge that Always On prevents apps from being unloaded due to inactivity. This is crucial for WebJobs and apps that need to respond quickly.
Tip 7: Custom Domain Requirements Custom domains require at least Basic tier. SSL bindings have specific requirements based on the type (SNI SSL vs IP SSL).
Tip 8: Authentication Options Know that App Service provides built-in authentication (Easy Auth) supporting Azure AD, Facebook, Google, Microsoft Account, and Twitter.
Common Exam Scenarios:
• Choosing the appropriate App Service Plan tier based on requirements • Configuring deployment slots for staging environments • Setting up auto-scaling rules based on CPU or memory metrics • Configuring application settings and connection strings • Implementing continuous deployment from source control
