Migrating an existing DotnetCore WebAPI into Azure Serverless function

Ramakrishna Pathuri

We have been migrating with Serverless computing for some time now. Recently we decided to check if it made sense to convert an existing dotnetcore WebAPI into a set of azure serverless functions.

Existing Implementation:- The existing DotnetCore WebAPI tech stack was as under

Database First Entity Framework core with SQL Azure
The internal code was layered into BL, DL with C#
JWT token authentication
Visual Studio 2019

Our “New” implementations as our decisions were influenced by “how much rework” we will need to do.

It should be possible to migrate the APIs to Azure Function without lot of rework. For the tokens, you can either look at AAD or try to setup another API using Azure Function that can generate the tokens using managed identity assigned to function app.

If you have different projects for DL, Business and API then probably the reworks needs to be done only in the controller end. Though the implementation of JWT in Azure Function is a bit tricky but you can always use AAD as part of the App Service Plan.
