Advanced Scaling Strategies

Autoscale Rules

# Create complex autoscale rule
az monitor autoscale create \
  --resource-group myResourceGroup \
  --resource myAppName \
  --resource-type "Microsoft.Web/serverfarms" \
  --min-count 2 \
  --max-count 20 \
  --count 5

# Add scale-out rule
az monitor autoscale rule create \
  --resource-group myResourceGroup \
  --autoscale-name myAppAutoscale \
  --condition "Percentage CPU > 80 avg 5m" \
  --scale out 2

# Add scale-in rule
az monitor autoscale rule create \
  --resource-group myResourceGroup \
  --autoscale-name myAppAutoscale \
  --condition "Percentage CPU < 30 avg 10m" \
  --scale in 1

Deployment Slots

# Create deployment slot
az webapp deployment slot create \
  --name myUniqueAppName \
  --resource-group myResourceGroup \
  --slot staging

# Swap slots
az webapp deployment slot swap \
  --name myUniqueAppName \
  --resource-group myResourceGroup \
  --slot staging

Performance Tuning

Application Performance Monitoring

const appInsights = require("applicationinsights");

appInsights.setup("<key>")
  .setAutoCollectPerformance(true)
  .start();

const client = appInsights.defaultClient;

// Track custom metrics
client.trackMetric({
  name: "CustomMetric",
  value: 42
});

// Track custom events
client.trackEvent({
  name: "CustomEvent",
  properties: {
    userId: "user123"
  }
});

Key Takeaways

• **Autoscale** rules enable intelligent scaling

• **Deployment slots** enable blue-green deployments

• **Application Insights** provides detailed diagnostics
