This guide provides a step by step, developer centric view of migrating legacy ASP.NET applications to Azure.
For a tool based approach using Azure Migrate: App Containerization tool, please see https://docs.microsoft.com/azure/migrate/tutorial-app-containerization-aspnet-kubernetes or https://docs.microsoft.com/azure/migrate/tutorial-app-containerization-aspnet-app-service, noting that (at the time of writing) the tooling doesn't support Apps that use Windows Authentication or have non IIS dependencies.
The application chosen for this guide is from the eShopModernizing repo. It's a DotNet Framework 4.7 Web Forms Application.
To iteratively work with the application, modernising it step by step to eventually run in a Windows 2022 container. Once containerised there will be guidance on running it in a number of Azure Container Compute services.
| Step # | Title | Description |
|---|---|---|
| 1 | Getting the app running locally | Using Visual Studio, we'll get the eShop app up and running |
| 2 | On a Virtual Machine | Getting the app running on an Azure VM. |
| 3 | SQL Database | Using SQL instead of the in-memory Database |
| 4 | App Service | Hosting the application in the App Service PaaS platform |
| 5 | Windows Containerisation | Focussing on creating a Windows Container |
| 6 | Windows Container Compute | Reviewing the options for running a Windows Container |
| 7 | Web App for Containers | Deploying the app to Web App for Containers |
| 8 | Kubernetes | Deploying the app to Kubernetes |
| 9 | Windows 2022 | Changing the base image, re-reviewing compute options |
