I just wanted to say that I really like the IBM Watson Studio platform. The user interface is excellent and there is plenty of knowledge based content available for user, which is helpful in when attempting to learn and implement new techniques and, or features. I can't speak from a performance standpoint, as I'm new to cloud based development, but IBM Watson Studio and DB2 Cloud are my prefered solutions compared to Azure and Cosmos DB. This is mainly based on on the user interface quality, availability of knowledge based content, and DB2 Cloud being an overall better product than Cosmos DB.
The only improvement that I would like to see in the future, is the addition of Jupyter Lab, which is already noted as being in future development plans.
Great work and thank you for the trail!
