So I finally got my test plan accepted for a 1 month trial to the Oracle Public Cloud at https://cloud.oracle.com/ .
Some initial thoughts- this Java cloud seemed more suitable for web apps, than for data science ( but I have to spend much more time on this).
I really liked the help and documentation and tutorials, Oracle has invested a lot in it to make it friendly to enterprise users.
Hopefully the Oracle R Enterprise ORE guys can talk to the Oracle Cloud department and get some common use case projects going.
In the meantime, I did a roundup on all R -Java projects.
