# Summary

> This lesson covers building a C# ASP.NET Core app, containerizing it with Docker, and preparing for deployment to Azure Kubernetes Service.

In this lesson, you’ve successfully:

* Scaffolded and built a C# ASP.NET Core web application
* Wrote a Dockerfile to containerize the app
* Ran and tested the image locally on Docker

You’re now ready to take the next step: deploy your container image to Azure Kubernetes Service (AKS) for a production-grade, highly available environment.

  Before deploying to AKS, ensure you have the [Azure CLI](https://learn.microsoft.com/cli/azure/install-azure-cli) installed and are logged into your Azure subscription:

  ```bash theme={null}
  az login
  az account set --subscription "<your-subscription-id>"
  ```
</Callout>

## Environment Comparison

| Environment                    | Deployment Tool               | Use Case                     |
| ------------------------------ | ----------------------------- | ---------------------------- |
| Local Docker                   | `docker build` / `docker run` | Development and testing      |
| Azure Kubernetes Service (AKS) | `az aks` / `kubectl`          | Production-grade scalability |
