This is great to see! This framework will allow defining functions that then can be run on many machines, gathering the output in fault-tolerant scale-out way.

This is great to see! This framework will allow defining functions that then can be run on many machines, gathering the output in fault-tolerant scale-out way. However, only AWS example is very limiting. I hope Azure and GCP gets added soon. Better docs on how infrastructure works underneath (Ray/Kubernetes?) would also be appreciated. I'd love to see an example that allows training ImageNet in just few minutes if cheap spot instances were available in cloud of your choice.
