Core Configuration Settings

Azure App Services offer a rich set of configuration options accessible through the Azure portal, Azure CLI, or PowerShell. Here are some of the most important settings:

Runtime Configuration Examples

Here are examples of how to configure common runtime settings:

Setting Environment Variables

Environment variables are crucial for managing application settings without hardcoding them. You can set them in the Azure portal under "Configuration" > "Application settings".

# Example using Azure CLI to set an environment variable
az webapp config appsettings set --resource-group MyResourceGroup --name MyWebApp --settings MY_API_KEY=your_secret_key ANOTHER_SETTING=value

Configuring .NET Core Application Settings

For .NET Core applications, App Service automatically maps application settings to your application's configuration provider.

// Accessing settings in C#
var connectionString = Environment.GetEnvironmentVariable("SQL_CONNECTION_STRING");

Configuring Node.js Application Settings

Node.js applications can access environment variables directly.

// Accessing settings in Node.js
const apiKey = process.env.MY_API_KEY;

Advanced Configuration Topics

Deployment Slots for Zero-Downtime Deployments

Deployment slots allow you to deploy your application to a staging environment before swapping it into production. This minimizes downtime and allows for thorough testing.

Networking and Security

Securing your App Service is paramount. Consider implementing VNet integration for hybrid connections and access restrictions to limit ingress traffic to trusted IP addresses or VNet subnets.

Performance Tuning

Monitor your application's performance using Application Insights and adjust your App Service Plan tier (scale up) or the number of instances (scale out) as needed. Enable "Always On" for non-serverless applications to keep them warm.
