# Summary

> This lesson covers leveraging Azure Kubernetes Service for scalable and resilient container orchestration, including deployment, scaling, and management of applications.

## Summary

In this lesson, you learned how to leverage Azure Kubernetes Service (AKS) for scalable, resilient container orchestration. Below is a structured recap of the main topics:

| Topic                               | Description                                                                            | Reference                                                                                    |
| ----------------------------------- | -------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| Kubernetes Overview                 | Core concepts of Kubernetes and why it’s the leading container orchestration platform. | [What is Kubernetes?](https://kubernetes.io/docs/concepts/overview/what-is-kubernetes/)      |
| Deploying an AKS Cluster            | Step-by-step process to provision an AKS cluster via the Azure Portal.                 | [Create an AKS cluster](https://learn.microsoft.com/azure/aks/kubernetes-walkthrough-portal) |
| Deploying Applications to AKS       | Packaging Docker images and deploying workloads with `kubectl apply`.                  | [Deploy to AKS](https://learn.microsoft.com/azure/aks/tutorial-kubernetes-deploy-cluster)    |
| Scaling Applications and Node Pools |                                                                                        |                                                                                              |

* Scale replicas with `kubectl scale`
* Adjust node pool size for capacity planning | [Scale AKS workloads](https://learn.microsoft.com/azure/aks/cluster-scale)               |
  \| Container Image Management              | Pushing images to Azure Container Registry (ACR) and granting pull permissions to AKS.     | [ACR integration](https://learn.microsoft.com/azure/container-registry/container-registry-auth-aks) |
  \| Application Upgrades and Rollbacks      | Implementing rolling updates and rollback strategies using `kubectl rollout`.              | [Rollouts in Kubernetes](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/#rolling-back-a-deployment) |
  \| Azure Kubernetes Fleet                  | Overview of multi-cluster management using Azure Fleet Manager.                            | [Azure Kubernetes Fleet](https://learn.microsoft.com/azure/fleet-manager/overview)       |

### Key Takeaways

* AKS reduces operational overhead by automating cluster management.
* You can seamlessly scale both pods and nodes to meet demand.
* Integrating with ACR ensures secure, private image pulls.
* Rolling updates and rollbacks keep your applications available during changes.
* Azure Kubernetes Fleet simplifies large-scale, multi-cluster governance.
