Container Apps Scaling Patterns

HTTP-based Scaling

Best for APIs and web applications:

scale: {
  minReplicas: 1
  maxReplicas: 10
  rules: [
    {
      name: 'http-scaling'
      http: {
        metadata: {
          concurrentRequests: '100'
        }
      }
    }
  ]
}

Queue-based Scaling

Best for background workers:

scale: {
  minReplicas: 0
  maxReplicas: 30
  rules: [
    {
      name: 'queue-scaling'
      azureQueue: {
        queueName: 'orders'
        queueLength: 10
        auth: [
          {
            secretRef: 'storage-connection'
            triggerParameter: 'connection'
          }
        ]
      }
    }
  ]
}

Service Bus Scaling

scale: {
  minReplicas: 0
  maxReplicas: 20
  rules: [
    {
      name: 'servicebus-scaling'
      custom: {
        type: 'azure-servicebus'
        metadata: {
          queueName: 'myqueue'
          messageCount: '5'
        }
        auth: [
          {
            secretRef: 'servicebus-connection'
            triggerParameter: 'connection'
          }
        ]
      }
    }
  ]
}
