I have roughed out a prototype/ proof of concept parameterised Rmarkdown report, and would like to be building (I think) a shiny app to allow non-technical users to access and run it at request.
I am aware of RConnect and shinyapps.io to provide built in authentication layers, however, I do not believe I will be able to obtain a license for those without a proof of concept for R, Rmarkdown and shiny first.
What are the frameworks/approaches that businesses use to 'roll their own' authentications? We use AWS extensively here, concurrency and processing load of this service will be low, but it will be required to be deployed to multiple users, ideally via a webpage with a user name password combination, though that's just a best guess approach, not a functional requirement.
