As described in a previous post, at Braintree, we use Ansible as the user data in the launch configurations (LC) of our autoscaling groups (ASGs) to configure instances on boot via a bash script with a base64 encoded tarball of the playbook directory. While we find this is a very effective way to structure the configuration, testing new configuration can be time consuming as it requires a new LC to be created and attached to the ASG followed by cycling an instance in the ASG by terminating it so that a new one, with the new configuration, takes its place.
