I'm looking to deploy my rails app but havn't decided yet on the setup.
mongrel_cluster+pound looks like the most simple solution but is it enough
(as in will it scale if the server gets a lot of visitors? or is
(pound?)+apache2+mongrel or anything else better?
It is recommended that you let a regular web server handle the static
file content. Mongrel can serve the static file content, but it is
supposed to make a more robust system.
Personnaly, I have Apache2 + mod_balance talking to Mongrel backends.
This is rock solid and have had no problems. Of course, I don't have
huge loads on the servers.
