Are there any ML-as-a-service platforms that offers something comparable to what Uber has here? And importantly, do you actually like using them?

That is, suppose I'm willing to do the following:

* Send said service a firehose of data

* Write code for feature selection, data cleanup, transformations, etc. -- i.e. the sort of code you'd expect to find in a data scientist's Jupyter notebook.

* Specify the type of ML model and parameters I'd like to experiment with.

Is there a service that handles data warehousing, serving up predictions via a REST API, deployment of new models, reporting model performance over time, and general scaling issues? I know it's possible to set up a large portion of this using AWS services, but ideally, it'd be nice to have something with a Heroku-like ease-of-use, but for ML.
