🎯 App Service Deployment

Introduction

Azure App Service is a fully managed platform for building and hosting web apps, mobile backends, and RESTful APIs.

Key Learning Outcomes

By the end of this lesson, you'll understand:

• Creating App Service plans and web apps

• Deploying applications (Git, ZIP, Docker)

• Configuring scaling and performance

• Managing custom domains and SSL

• Monitoring and logging

• Environment variables and configuration

Creating App Service

# Create App Service plan
az appservice plan create \
  --name myAppServicePlan \
  --resource-group myResourceGroup \
  --sku B1 \
  --is-linux

# Create web app
az webapp create \
  --resource-group myResourceGroup \
  --plan myAppServicePlan \
  --name myUniqueAppName \
  --runtime "node|18-lts"

Deploying Applications

Deploy from Git

# Configure git deployment
az webapp deployment source config-zip \
  --resource-group myResourceGroup \
  --name myUniqueAppName \
  --src myapp.zip

Deploy from Docker

# Create web app with Docker
az webapp create \
  --resource-group myResourceGroup \
  --plan myAppServicePlan \
  --name myUniqueAppName \
  --deployment-container-image-name myregistry.azurecr.io/myapp:latest

Configuration

Node.js Express App:

const express = require('express');
const app = express();

const PORT = process.env.PORT || 3000;

app.get('/', (req, res) => {
  res.send('Hello from Azure App Service!');
});

app.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`);
});

Scaling

# Set up autoscale
az monitor autoscale create \
  --resource-group myResourceGroup \
  --resource myUniqueAppName \
  --resource-type "Microsoft.Web/sites" \
  --min-count 1 \
  --max-count 10 \
  --count 2

Custom Domain and SSL

# Add custom domain
az webapp config hostname add \
  --resource-group myResourceGroup \
  --webapp-name myUniqueAppName \
  --hostname mycompany.com

Key Takeaways

• **App Service** is a managed platform for web apps

• **Automatic scaling** handles variable load

• **Multiple deployment options** (Git, Docker, ZIP)

• **Custom domains** and SSL are built-in

• **Monitoring** provides performance insights
