There are a few ways to open Jupyter notebooks in the cloud pretty easily:

https://aws.amazon.com/sagemaker/

https://cloud.google.com/datalab/

https://gryd.us/

https://kyso.io (disclaimer - I'm a founder)

Do you want it to be so easy that you jump into the notebook immediately upon logging in, the hard part is that javascript will run in your browser - but python or R need a kernel running somewhere?
