Migrating an existing DotnetCore WebAPI into Azure Serverless function

Question

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.
