Sanau seems like a new version of Sagemaker https://aws.amazon.com/sagemaker/ where you write code in Jupyter and it auto converts to endpoints.

I've used these solutions, but while Jupyter is amazing (my startup https://kyso.io started as a way to share notebooks) I'm not sure if deducing which cells to convert into an endpoint is the way to go - especially since you will need to also host model files and extra data?
