Hi Navan,
This looks more about how to deploy from .NET to AWS not related to the revit api at all. The same process can be done to other hosting services, Azure, Heroku for example.
I don't think of the Revit SDK as a Cloud API to be honest. It can talk to cloud api's and web services, similar to what the BIM 360 glue plugin does from Revit. But not as a service hosted somewhere. Can you elaborate more on what your plan is, maybe it can clarify more my thoughts and suggest something.
Thanks for joining Answer day!
Cheers,
