Thanks a lot for the input and reply! A lot of good material, tips and resources! 

We're already using the Shiny Notebooks hosting, but we're wondering if it was possible to migrate to the new Databricks Apps? Seems like a better fit, and we also saw that it also supports Shiny, but that might be only the Python implementation of Shiny? Do you recommend to stay with Notebook hosting for now?

For the model hosting we're already crate and adding the renv when logging to mlflow, but not the Pyfunc wrapping. We'll give that a try. Do you have some code examples for the second part "Add Additional Artifacts"? That would be really helpfull!

BR,
Anton
