OpenShift is a PaaS by Redhat. It offers a free plan to attract users.

https://github.com/githwxi/ATS-Postiats-frozen/tree/master/projects/SMALL/openshift-python-2016-07-20Basically, all that is needed is to make libatscc2py3 available on PYTHONPATH (so that various functions
called in the python3 code generated from ATS source can be properly located).
For OpenShift-nodejs and OpenShift-php, similar things can be done.
