I am a big lover of R/Shiny and RStudio.
Now I am working on data app product with Shiny dashboard.
The only one problem is how to use Shiny in real-life production with users authorization, and etc. The codebase is on AWS instance with shiny-server installed.
Will be happy to make RShiny dashboards in production!
Shiny Server Pro, the commercial version of Shiny Server, supports many types of authentication, has a metrics dashboard, and works well in AWS. It costs money, but you can try it free for 45 days to see if it meets your needs.
You can also get a Standard plan on http://www.shinyapps.io/ that will let you authenticate your shiny app users, if using a cloud service rather than installing your own server is better for you.
