The Promotion tool is designed to make it easy and quick to deploy an application into production. Originally built for use with OpenBSD, it can be used on an *nix system by adjusting a few paths (in config.rb). To deploy or install an application you just need to copy a few files into place, right? Well, the folders need to be there first of course, oh and the permissions need to be set, and I guess we need the right users set up before file ownerships can be set correctly, which means we need groups before that ... ok, so there is more to it than copying a few files. There are also system-wide settings that may need to be modified to support an application, such as environment variables in /etc/profile, /etc/sudoers, startup scripts in /etc/rc.conf.local, and /var/cron/tabs/* cron jobs. Promotion does not modify these sensitive files, but it does say how to change them. Promotion handles all of this based on an XML deployment descriptor for each application, allowing rapid, reliable redeployment with a single line command (promote). It also manages database schema migration with the evolve/devolve commands.

YamlDb is a database-independent format for dumping and restoring data. It complements the the database-independent schema format found in db/schema.rb. The data is saved into db/data.yml. This can be used as a replacement for mysqldump or pg_dump, but only for the databases typically used by Rails apps. Users, permissions, schemas, triggers, and other advanced database features are not supported - by design. Any database that has an ActiveRecord adapter should work
