I'll post the example source code here tomorrow after the talk (still tweaking it).

OK thanks! How about persisting files (which actually isn't possible on Heroku but we would like to persist files on disk for simplicity so are debating about just using AWS)?

We provide an in-memory writable filesystem (e.g. you want to do file transformations) but it's not persistent across all instances. We're looking into Filestore integration for a mountable NFS product, though as mentioned in another comment about that, reading is easy but writing is hard.
