>From the Amazon web service stanpoint, it woud be idea to have a completely standaalone package which deploys itself, or the use of a parameter which is documented here ... http://docs.amazonwebservices.com/elasticbeanstalk/latest/ug/index.html?using-features.managing.db.htmlwhich can be used to connect to a persistent source, like a remote Postgres DB or the Amazon RDS server. Being able to pass a paramater directly to the instance could be useful from the AWS stand point.
Will give it a try anyway. Thanks.
