The rubber plugin enables relatively complex multi-instance deployments of RubyOnRails applications to Amazon's Elastic Compute Cloud (EC2). Like capistrano, rubber is role based, so you can define a set of configuration files for a role and then assign that role to as many concrete instances as needed. One can also assign multiple roles to a single instance. This lets one start out with a single ec2 instance (belonging to all roles), and add new instances into the mix as needed to scale specific facets of your deployment, e.g. adding in instances that serve only as an 'app' role to handle increased app server load.

Simple Rails deployment and configuration management. 15 minute deploys of Rails 2, 3, or 4 apps.

Manage multiple Heroku instances/apps for a single Rails app using Rake

Tomo is a feature-rich deployment tool that contains everything you need to deploy a basic Rails app out of the box. It has an opinionated, production-tested set of defaults, but is easily extensible via a well-documented plugin system. Unlike other Ruby-based deployment tools, tomo’s friendly command-line interface and task system do not rely on Rake.
