Solution
Have a look at Heroku pre-boot it's a labs feature but sounds like exactly what you need.
Problem
We're currently running a Ruby on Rails project (RefineryCMS) on Heroku with two dynos. Every time we update the site we experience downtime for about 1 to 2 minutes. Management are not happy about this. What we'd really like is some sort of (transparent) Blue-Green Deployment: http://martinfowler.com/bliki/BlueGreenDeployment.html Is this possible to achieve on Heroku or another cloud platform as a service? We're also using Unicorn, but happy to change if necessary.
