I am surprised by this - h2o.ai seems to have many if not all of the features of this, and is open source.
"Specifically, there were no systems in place to build reliable, uniform, and reproducible pipelines for creating and managing training and prediction data at scale. Prior to Michelangelo, it was not possible to train models larger than what would fit on data scientists’ desktop machines, and there was neither a standard place to store the results of training experiments nor an easy way to compare one experiment to another."
Seems like h2o.ai fits a lot of that bill.
