 Azure Kubernetes Service (AKS) is a managed Kubernetes service that lets you quickly deploy and manage clusters. In this quickstart, you deploy an AKS cluster using the Azure portal. A multi-container application that includes a web front end and a Redis instance is run in the cluster. You then see how to monitor the health of the cluster and pods that run your application.

 > [!NOTE]
 > You can also configure the load balancer to be internal and not expose a public IP. To configure the load balancer as internal, add `service.beta.kubernetes.io/azure-load-balancer-internal: "true"` as an annotation to the *LoadBalancer* service. You can see an example yaml manifest as well as more details about an internal load balancer [here][internal-lb-yaml].
