The tutorial explains how to containerize an existing .NET Core app with Docker and deploy it to Azure Kubernetes Services (AKS). The process involves refactoring the application using cloud-native principles, abstracting infrastructure dependencies, and deploying it to AKS. The tutorial covers various aspects of cloud migration patterns, including lift and shift, refactor, re-architect, and rewrite. It also provides guidance on building a Docker file, creating an Azure Container Registry (ACR), and deploying the application to AKS. The process involves creating a PowerShell script to build the infrastructure, including an AKS cluster and ACR, and then deploying the application to AKS using a YAML file. The tutorial concludes with instructions on how to test the deployed application and remove the test deployment when finished.
