@stefan-hanke There’s some classes in France, plus a book written in French. Not helpful for most of us. There currently isn’t any ‘fogproject blessed’ training.
As far as documentation goes for distributed setups, we have these two articles:
https://wiki.fogproject.org/wiki/index.php?title=Replication
https://wiki.fogproject.org/wiki/index.php?title=Location_Plugin
I’ve been wanting to create some more videos on distributed fog setup, tried to do it a few months ago but ran into some problem.
