Running Erlang Webmachine on Heroku

this is great but one of the real advantages of Erlang is the ability to pass messages between processes on different nodes (or, in the heroku case dynos) without worrying about which node you're on, but it's impossible for different nodes to communicate on heroku as they won't open the EPMD ports (and won't allow an EPMD daemon to run). This means Erlang on Heroku is still going to be limited.

OK, I see how to run a simple web server, like Mochiweb on Heroku Cedar stack. But how do I connect to database? How do I write to log?

You can connect to any database you want to just like you would anywhere else.

You write to your logs by writing to stdout/stderr: http://devcenter.heroku.com/articles/logging#writing_to_your...

Can you elaborate about the DB part? You mean people using Cedar stack should use database hosted elsewhere? I.e. something like AWS RDS or MongoHQ?

My question was about using Heroku's shared Postgres database, like usual Rails apps using Bamboo stack.

This is good news. Now if they will just support Riak, I might be able to port nirvana to it. (Nirvana is the coffeescript/javascript distributed web platform I'm building for our startup. It runs across a riak cluster and distributes javascript in a concurrent manner over it.)

Nirvana is really "just" a webmachine App.

PS: My startup entered Startup Chile which is announcing results today: http://news.ycombinator.com/item?id=3361777
